A DIGITAL INFORMATION LIBRARY
AND DELIVERY SYSTEM
The present invention relates generally to a digital information transmission, receiving,
and playback system. Specifically, the present invention pertains to a computer network based
digital information library providing interactive client computer access.
M
Recent technological advances in the compression of digital data and the expansion of
storage capacities of computer systems together with the increased bandwidth of computer
network infrastructures have created new possibilities for personalized access to and usage of
large amounts of digital information. One form of this type of digital information is audio
information delivered across a computer network as digitized information.
In the field of interactive digital information transmission, receiving, and playback
systems, several patents are known to the present applicants. U.S. Patent No. 5,132,992, issued
July 21, 1992 to Yurt et al. (Yurt),_ describes a system of distributing video and/or audio
information employing digital signal processing to achieve high rates of data compression. The
Yurt patent describes a transmission system including a conversion means for placing the items
from a source material library into a predetermined format as formatted data. Audio data is
compressed by an audio compressor by application of an adaptive differential pulse code
modulation (ADPCM) process to the audio data. Stored items are accessed in the compressed data
library through the use of a unique address code assigned to each item during storage encoding.
The unique address code is used for requesting and accessing information and items throughout
the Yurt transmission and receiving process. The Yurt transmission system includes means by
which a user enters a customer identifier (ID) code by which the system accesses the users
account, and indicates to the system that the user is a subscriber of the system. If a subscriber is
in good standing, the Yurt system delivers selected titles using the described techniques.
One significant problem with the audio transmission and receiving system described in
Yurt is the lack of an effective means for ensuring the security of the digital information library
and of the items downloaded to a user from the digital information library. Although Yurt
describes the use of a unique identi?cation code assigned to items in the library and a customer ID
code assigned to particular users, no authentication protocols or encryption techniques are
described to prevent the unauthorized creation of clone libraries or the unauthorized download or
copying of library items. Secondly, Yurt and related prior art does not describe an authentication
or encryption means providing secure transactions between a server based digital information

library supporting a client computer system having an interface to a mobile playback device.
Thirdly, the prior art does not describe a mechanism for selecting a digital information passage to
be previewed. Prior art systems also do not describe a system whereby only part of a program
gets downloaded from a client computer system to a mobile playback device depending on how
much storage space is available in the mobile playback device. Prior art systems also do not
describe a mechanism for specifying multiple programs to be downloaded from a digital
information library into a mobile playback device. Prior art systems also do not detail the
processes required in the authoring system to generate content for the digital information library.
Finally, prior art systems do not describe an accounting system whereby library content providers
can perform real-time queries on usage information related to the access of library items.

The preferred embodiment of the present invention is a computer network based digital
information library system employing authentication, targeting, and encryption protocols for the
secure transfer of digital information library programs to a client computer system and a mobile
digital information playback device removably connectable to the client computer system. In the
following detailed description, numerous specific details are set forth in order to provide a
thorough understanding of the present invention. However, it will be apparent to one of ordinary
skill in the art that these specific details need not be used to practice the present invention. In other
instances, well known structures, interfaces, and processes have not been shown in detail in order
not to unnecessarily obscure the present invention.
Figure 1 illustrates a typical data processing system upon which one embodiment of the
present invention is implemented. It will be apparent to those of ordinary skill in the art, however
that other alternative systems of various system architectures may also be used. The data
processing system illustrated in Figure 1 includes a bus or other internal communication means
101 for communicating information, and a processor 102 coupled to the bus 101 for processing
infonnation. The system further comprises a random access memory (RAM) or other volatile
storage device 104 (referred to as main memory), coupled to bus 101 for storing information and
instructions to be executed by processor 102. Main memory 104 also may be used for storing
temporary variables or other intermediate information during execution of instructions by
processor 102. The system also comprises a read only memory (ROM) and/or static storage
device 106 coupled to bus 101 for storing static information and instructions for processor 102,
and a mass storage device 107 such as a magnetic disk drive or optical disk drive. Mass storage
device 107 is coupled to bus 101 and is typically used with a computer readable mass storage
medium 108, such as a magnetic or optical disk, for storage of information and instructions. The
system may further be coupled to a display device 121, such as a cathode ray tube (CRT) or a
liquid crystal display (LCD) coupled to bus 101 through bus 103 for displaying information to a
computer user. An alphanumeric input device 122, including alphanumeric and other keys, may
also be coupled to bus 101 through bus 103 for communicating information and command
selections to processor 102. An additional user input device is cursor control 123, such as a
mouse, a trackball, stylus, or cursor direction keys coupled to bus 101 through bus 103 for
communicating direction information and command selections to processor 102, and for
controlling cursor movement on display device 121. Another device which may optionally be
coupled to bus 101 through bus 103 is a hard copy device 124 which may be used for printing
instructions, data, or other information on a medium such as paper, film, or similar types of
media. In the preferred embodiment, a communication device 125 is coupled to bus 101 through
?CA 02265549 l999-03- 10
WO 98/11487 PCT/US97/16184
6
bus 103 for use in accessing other nodes of a network computer system or other computer
peripherals. This communication device 125 may include any of a number of commercially
available networking peripheral devices such as those used for coupling to an Ethernet, token ring,
Internet, or wide area network. It may also include any number of commercially available
peripheral devices designed to communicate with remote computer peripherals such as scanners,
terminals, specialized printers, or audio input/output devices. Communication device 125 may
also include an RS232 or other conventional serial port, a conventional parallel port, a small
computer system interface (SCSI) port or other data communication means. Communications
device 125 may use a wireless means of data transfer devices such as the infrared IRDA protocol,
spread-spectrum, or wireless LAN. In addition, communication device 125 is used in the
preferred embodiment to couple the mobile playback device 212 to the client computer system 214
as described in more detail below. One other device used in the preferred embodiment is sound
circuitry 130 either with attached speakers or headphones 132, or with analog audio outputs
suitable for input into audio reproduction equipment such as external amplifiers and speakers,
cassette adapters, etc. Sound circuitry 130 is well known in the art for playing audio files.
Alternatively, sound circuitry may be a radio transmitter which transmits audio data on a
prede?ned frequency for reception and playback by a radio receiver. Other wireless methods are
possible.
Note that any or all of the components of the system illustrated in Figure 1 and associated
hardware may be used in various embodiments of the present invention; however, it will be
appreciated by those of ordinary skill in the art that any configuration of the system may be used
for various purposes according to the particular implementation. In one embodiment of the
present invention, the data processing system illustrated in Figure 1 is an IBM® compatible
personal computer (PC), an Apple MacIntosh® personal computer, or a SUN® SPARC
Workstation. Processor 102 may be one of the 80X86 compatible microprocessors such as the
80486 or PENTIUM® brand microprocessors manufactured by INTEL® Corporation of Santa
Clara, California.
The software implementing the present invention can be stored in main memory 104, mass
storage device 107, or other storage medium accessible to processor 102. It will be apparent to
those of ordinary skill in the art that the methods and processes described herein can be
implemented as software stored in main memory 104 or read only memory 106 and executed by
processor 102. This software may also be resident on an article of manufacture comprising a
computer usable mass storage medium 108 having computer readable program code embodied
therein and being readable by the mass storage device 107 and for causing the processor 102 to
perform digital information library transactions and protocols in accordance with the teachings
herein.

Digit? Informatign Library System
Figure 2 illustrates the computer network architecture used in the preferred embodiment of
the present invention. In general, the network architecture of the present invention includes a
library site 250 coupled to a client site 210 via a conventional distribution network infrastructure
240. This conventional distribution network infrastructure 240 can be implemented as a standard
telephone connection provided between the library site 250 and client site 210 through an Internet
provider to enable data communication on the Internet over a conventional telephone network.
This use of the Internet as a distribution network is well known to those of ordinary skill in the
art. In an alternative embodiment having cable modem capability, communication over a
conventional cable network is possible in lieu of communication over the telephone network. The
cable network is typically much faster (i.e. provides a much greater bandwidth) than the standard
telephone network; however, cable modems are typically more expensive than standard POTS
(plain old telephone system) modems. In another alternative embodiment having conventional
Integrated Services Digital Network (ISDN) capability, the distribution network 240 is accessed
using an ISDN modem. Again, the ISDN network is typically faster than the POTS network;
however, access to an ISDN network is generally more expensive. Cable modems and ISDN
implementations are alternative communications media to the POTS implementation.
In addition, it will be apparent to those of ordinary skill in the art that other forms of
networking may equivalently be supported by the present invention. For example, a wireless
transmission means such as infrared or radio links may also provide the distribution network 240
described in the present application. As an alternative to the Internet, a proprietary network/bulletin
board such as AMERICA-ON-LINE (AOL), or COMPUSERVE may be used.
Each of the servers at library site 250 and the client computer system 214 at client site 210
can be implemented as a computer system such as the one described above in connection with
Figure 1. It will be apparent to one of ordinary skill in the art that the library server 260, authoring
system 280, and authorization server 270 can be remotely located yet networked together as a
distributed system using the techniques described above. In addition, the present invention allows
for multiple library servers, authoring systems and authorization servers. Conversely, the servers
may be implemented as separate functions of a single machine. These alternative embodiments are
illustrated in Figures 4â8 and are described in more detail below.
The mobile playback device 212 is a minimally con?gured, lowâcost, standalone mobile
unit for receiving and storing digital information ?les or programs as downloaded by library
server 260 and client computer system 214 and for playing back the digital information ?les or
programs for a user of the mobile playback device 212. The mobile playback device 212 is
temporarily removably coupled to the client computer system 214 while the download takes place.
?CA 02265549 l999-03- 10

Once downloaded, the mobile playback device 212 may be detached from the client computer
system 214 and used as a standalone digital information playback device. A co-pending U.S.
Patent Application titled, "Interactive Audio Transmission, Receiving and Playback System",
assigned Serial No. 08/490,537, and assigned to the Audible Words Corporation of Montclair, NJ
describes the details of mobile playback device 212.
In its basic form, the preferred embodiment of the present invention is a digital information
library system providing selection of digital information programming on demand over a computer
network. In an alternative embodiment, the digital information programming is selected via the
computer network but delivered using mass storage media 241. This alternative embodiment is
described in more detail below.
The digital information library is an indexed collection of digital information programming,
drawing content from digital information sources such as books, daily news and entertainment
feeds, conferences and educational sources, other computer systems, the host on the World Wide
Web (WWW) of the Internet, and customized audio or visual image programming. Other sources
of the digital information content include, but are not limited to, conference or seminar
proceedings, lecture or speech materials, language lessons, readings, comedy, customized spoken
digests and related, "need-to-know" business information, computer software, local sound studio
material, text to speech conversion of machine readable ?les, pre-recorded material from magnetic
tape, CD-ROM, digital audio tape, or analog cassette tape. This digital information content is input
as raw digital information content to authoring system 280 shown in Figure 2. In an alternative
embodiment, a raw digital information digitizer 307 is included for receiving raw input and
converting the input to a digital form which can be manipulated as a digital information file.
In an alternative embodiment, the digital information comprises digitized image or graphics
data used to produce visual images on a display screen or projection screen. These images may be
included in the digital information retained and maintained by the library server 260.
Authoring §y§tem
Authoring system 280 is used to edit, index, compress, scramble, segment, and catalog
digital information content into digital information programs in digital information ?les, which are
stored on mass storage media 241 or on library server 260 as scrambled and compressed digital
information ?les 262. The digital information programs are initially categorized according to
traditional criteria (e. g. genre, modern ?ction, mystery, adventure, romance, non-fiction, classics,
selfâhelp, science fiction, westerns, etc.). Categories associated with specific authors or
publishers are also provided. Both unabridged and abridged titles are provided. In some
circumstances, it may be necessary to digitize digital information content from an undigitized
form. The raw information digitizer 307 is provided for this purpose. Authoring system 280 also
?CA 02265549 l999-03- 10
wo 93/1 1437 PCT/US97/16184

partitions digital information content into segments, which can be identi?ed, searched, and
skipped over if desired. All of these functions are performed by authoring system 280.
Figure 3 illustrates the authoring system 280 of the preferred embodiment. Authoring
system 280 receives digital information content from a variety of conventional sources as raw
digitized data. This digital information data is fed to three components of the authoring system 280
of the preferred embodiment. The digital information compressor 314 receives the raw digital data
and compresses the digitized data. There are a variety of conventional techniques in existence for
compressing digital data. These techniques can be optimized depending upon the type of digital
data being processed. Thus, the present invention provides several compression methods and a
means for the authoring system operator 305 to select between these methods based upon the
category of digital information content 310 being input to the digital information compressor 314.
Alternatively, the selection of compression method may be performed automatically by
interpretation of the digital information content 310 itself. A compressed digital information file is
output by digital information compressor 314 to scrambler 318.
The raw digital information content 310 is also fed to template header generator 312. Each
digital information ?le maintained by the library server 260 includes other descriptive information
used to identify the file's content and to provide information used to process the digital
information within the ?le. Each digital infomiation file includes a template header, a descrambling
map, selected preview clips, and the digital information programming itself. In the preferred
embodiment, the template header comprises a number of attributes corresponding to the digital
information in the file. For example, the digital information may be audio information generated
from the content of a book or other published work. In this example, the audio file template header
contains attributes including: 1) the title of a book, volume, or medium from which the digital
information content originated, 2) the legal copyright associated with the digital information
content, 3) audible tit1e(s) of the content, 4) a table of contents of the content, and 5) playback
settings for appropriately playing or rendering the digital information. The table of contents
contains content navigation information including but not limited to: the number of chapters, the
length of the program, and information indicative of the relevant content sections. The table of
contents is generated with input from authoring system operator 305 or automatically by analysis
of digital information content 310. The descrambling map 322 is used to interpret the digital
information after the digital information has been scrambled by scrambler 318 as described below.
The preview clips 324 comprise short preâ generated portions of digital information content used to
give a consumer a sense of the content of a particular digital information file. In the preferred
embodiment, these previews are generated as conventional formatted files which can be directly
played by sound generation circuitry 130 or rendered by other means. A digital information file
can have several preview clips associated with it. The preview clips 324 are not compressed or
?CA 02265549 l999-03- 10
W0 98/1 1487 PCT/US97/16184
10
scrambled in the preferred embodiment. The template header 312 remains with the digital
information ?le as it is transferred to the network 240 or mass storage media 241. The other
descriptive information related to a digital information file is typically stored with digital
information ?le, but is not required to be so stored.
Referring again to Figure 3, template header generator 312 generates the template header
given information from a particular portion of digital information content 310. Input from
Authoring System Operator 305 and Digital Information Compressor 314 may be solicited during
the header generation process. The template header is provided to library server 260. Other
portions of the digital information file header are provided by scrambler 318 and preview
generator 323. These portions of the digital information file header are assembled into the header
for a particular digital information file by library server 260. The remainder of the digital
information ?le is ?lled with compressed, scrambled, and segmented digital information content.
After digital information compressor 314 has compressed the raw digital information using
a selected compression method suitable for the category of digital information, the scrambler 318
scrambles the digital information. The digital information is scrambled to prevent an unauthorized
consumer from using the digital information. In the preferred embodiment, scrambler 318 uses a
conventional encryption method to render the data unusable. A correspondin g descrambling map
322 is generated to provide a means for descrambling the scrambled digital information file. A
scrambling map 316 is used by scrambler 318 to scramble the digital information file. The
scrambler 318 can encrypt the entire digital information ?le or selected critical subsets of the digital
information ?le. The level of scrambling can be selected depending upon the capabilities of the
authoring system 280, the mobile playback device 212 and/or the anticipated software player 226
on client computer system 214. In an alternative embodiment, a proprietary digital information
format is used in lieu of scrambler 318.
The scrambled digital information content is output by scrambler 318 to segmentation logic
326. Segmentation logic 326 partitions the digital information content into blocks for efficient
storage in and transfer to a mobile playback device 212 or software player 226 and for efficient
navigation during playback. Transport integrity data is generated and appended to the segmented
digital information. In an alternate embodiment, portions of the segmentation process may take
place before or after digital information compressor 314 and scrambler 318. Segmentation
information may also be used in the header generation process by template header generator 312.
The compressed, scrambled, and segmented digital information blocks are provided to the library
server 260 by authoring system 280. Library server 260 assembles the segmented digital
information blocks, the descrambling map 322, the preview clip(s) 324, and the template header
312 for a particular item of digital information content into a digital information program ?le or
files, which are stored in a digital information program ?le storage area 262. Other raw digital

information content is converted into digital information files using the authoring system 280 in a
similar manner.
Librgy Sewer
Referring again to Figure 2, the library server 260 is responsible for maintaining the digital
information program ?les 262 created by the authoring system 280. In addition, the library server
260 receives requests for access to the digital information program ?les 262 from client computer
systems 214 over network 240 and manages purchase and delivery of the selected digital
information ?les and/or delivery of selected preview clips 324. The library server 260 includes
library management software 261 for performing these library server functions and a library key
263 used for the authentication protocol described below. Library management software 261
includes processing logic for receiving and responding to client computer system 214 requests for
access and/or purchase of a digital information program file 262. Upon receiving such a client
request, library server 260 uses authorization server 270 to authenticate the request with client
information 272 generated and maintained by library server 260 or authorization server 270. The
client information 272 includes client identi?ers which are used to target content for playback on
individual mobile playback devices 212 or software players 226. Client information 272 may also
contain client personal information, user content preferences, client billing history, player usage
history, and player group lists. In an alternative embodiment, portions of client information 272
may instead be stored in server 260. Using the authorization protocol described in more detail
below, the library server 260 determines if the client request can be serviced. If approved, the
library server 260 accesses the digital information program ?le(s) or preview clip(s) requested by
the client computer system 214, delivers the selected preview clip(s) or builds encrypted, targeted,
and digitally signed digital information ?les using the authentication protocol described in more
detail below, and transfers the encrypted and compressed digital information file(s) to the
requesting client computer system 214 via network 240. Distributable mass storage media 241
may also be used as a delivery medium for the transfer of information to client system 214. The
client computer system 214 may then independently download the selected digital information ?les
(or a subset thereof) into the mobile playback device 212 for subsequent playback. The library
server 260 also collects usage statistics on the access history of the digital information files 262
and stores this usage data into usage statistic storage area 264. The library server 260 also stores
operating code segments (firmware) for the client browser 219, software player 226, and for
mobile playback device 212. This operating code can be downloaded to the client computer system
214 in the same manner as digital information ?les are transferred. Player con?guration data for
playback device 212 and software player 226 is stored on the library server 260 and can be
customized or updated in the same manner as digital information ?les and firmware are
?CA 02265549 l999-03- 10
W0 98/1 1487 PCT/U S97/ 16184
12
uansferred. Configuration data includes, but is not limited to, audio prompts, user interface
options, group ID information, and infonnation playback parameters. Player con?guration data is
transferred to client computer system 214, software player 226, or mobile playback device 212 as
required according to client information 272.
The library server 260 interfaces with a client application program or client browser 219
executing on client computer system 214. The client browser 219 is used to make requests of
library server 260 for various types of service including, but not limited to, searching the digital
information files 262 for a desired program, previewing a selected preview clip associated with a
digital information ?le 262, purchasing a selected program, requesting operating code segments or
player configuration data, and downloading the purchased program or other material to the
requesting client computer system 214.
The library server 260 interface with the authorization server 270 and client computer
system 214 uses the unique authentication protocol and encryption protocol of the preferred
embodiment of the present invention. The preferred embodiment of these protocols is described in
the sections below.
Client Computer System
Referring again to Figure 2, the client computer system 214 represents a consumer or end
user computer system, typically a personal computer, such as the sample system illustrated in
Figure 1, with which a consumer may browse, preview, select, purchase, and take delivery of
digital information content from digital information library server 260 across distribution network
240. Client computer system 214 comprises client browser software 219, a mobile device
interface 221, storage for encrypted and compressed digital information files 220 downloaded
from the network 240, software player 226, and segment download data 222 derived from digital
information files 220 for defining the storage segments in mobile playback device 212 and for
assisting in the downloading of digital information files 220 from client computer system 214 to
mobile playback device 212. Client computer system 214 also includes a server public key 215
used for authenticating digital information and software ?les received from server 260. Client
browser software 219 provides the control logic with which the client or consumer accesses and
purchases titles from the digital information library 262 of library server 260. Client browser
software 219 also provides control logic which requests and downloads configuration information
or operating code from server 260. The client browser software 219 can be con?gured to perform
these operations without direct human intervention. The mobile device interface 221 is a software
interface used to control the transfer of control information, operating code, and digital
information files from client computer system 214 to mobile playback device 212. Encrypted and
compressed digital information ?les 220 are received by client computer system 214 from library
?CA 02265549 l999-03- 10
W0 98/1 1487 PCT/U S97/ 16184
13
server 260 over network 240. In an alternate embodiment, distributable mass storage media 241
is used instead of network 240 to transfer information to client computer system 214. The
software player 226 is a software module used to emulate the operation of mobile playback device
212 and for playing digital information files through the sound circuitry 130 and audio output
device 132 of client computer system 214. Operating code and configuration information for the
software player 226 can be downloaded or updated from the server 260 in the same manner as the
mobile playback device 212 can be downloaded or updated. The software player 226 functionality
is the equivalent of the functionality and operation of the mobile playback device 212. Thus, the
use of the term "player" throughout this document generally applies to both the mobile playback
device 212 and software player 226. Software players 226 are assigned unique player IDs and can
be assigned group IDs that function similarly to IDs assigned to mobile playback devices 212.
Mobile Playback Device
The mobile playback device 212 converts a digital information file into sound or
displayable imagery which is played through audio output means or displayed on a display device.
In the preferred embodiment, the mobile playback device 212 is a minimal capability, low-cost
device primarily dedicated to playing audio files or displaying visual images or text on a display
device. The mobile playback device 212 is minimally configured to retain its light-weight, low
cost, and readily mobile features. The preferred embodiment does not therefore include the use of
a portable personal computer or laptop computer as the mobile playback device 212; because, such
general purpose computing devices typically do not meet the light-weight and low cost constraints
of the preferred mobile playback device 212. Such general purpose computing devices typically
have unnecessary functionality, more complicated interfaces, and may suffer cost and performance
penalties in comparison to the special purpose mobile playback device 212. In the preferred
embodiment, the mobile playback device 212 includes a processor, memory, and an interface to
client computer system 214 over which compressed digital information ?les 216 are received. As
described in more detail below, mobile playback device 212 also includes a player ID 223, group
IDs 225, and server public key 215 used for authenticating digital information and software ?les
received from server 260 via client computer system 214. The user controls the mobile playback
device 212 using buttons and knobs provided on the device. These controls are used to navigate
through digital information files 216, adjust con?guration data and playback parameters, or
perform other functions as directed by ?rmware stored in playback device 212. When coupled to
the player, client computer system 214 or other electronic devices can solicit user input from these
controls. In an alternative embodiment, a set of additional user controls is provided on a remote
control unit that is coupled to the player via a wired or wireless connection. Digital information
output may be provided via a headphone jack, on board speaker, or wireless transmitter to a
?CA 02265549 l999-03- 10
W0 98/1 1487 PCT/US97/16184
14
separate wireless receiver with speakers or headphones. Audio level can be adjusted with a
volume knob. A wireless transmitter may contain an adjustment knob to adjust the transmission
frequency or other transmission parameters. Visual information output is provided via LCD
display, LED display, or outputs to a standard visual display device. The mobile playback device
212 contains a limited quantity of non-volatile memory, RAM, and ROM. Digital information
content, configuration data, and operating code are stored in the memory space of the mobile
playback device 212. Con?guration data includes but is not limited to: public and private IDs,
content playback parameters, and user interface parameters. The use of non-volatile memory
allows portions of the digital information content, con?guration data, and firmware to be updated
via download. Both digital information content and firmware (operating software) is stored in this
memory device. Portions of the firmware and con?guration information are stored permanently in
a read only memory (ROM). An internal memory allocation method is used to track the content of
mobile playback device 212 memory. This allocation method, in conjunction with segment
navigation data 218, also provides the means for locating desired digital information, program,
con?guration data, or header data resident in the mobile playback device 212 memory. The mobile
playback device 212 includes an interface to the client computer system 214 through which the
mobile playback device 212 receives compressed digital information files 216, software updates,
and con?guration changes from client computer system 214.
Downloading Digital Information Content, Software Updates, or Con?guration Infonnation From
the Libra_ry Server to the Client Computer System
The client browser software 219 of client computer system 214 operates in cooperation
with library management software 261 of library server 260 and the firmware resident on the
mobile playback device 212 to provide a means by which a consumer may browse, preview,
select, purchase, and take delivery of selected digital information content from digital information
library server 260 across distribution network 240. The digital information content is typically
downloaded to the client computer system 214 at the time of purchase, but it is possible to
download digital information content either, 1) sometime after the purchase, or 2) multiple times
after an initial purchase. The client browser 219 can be configured to download content to client
computer system 214 without user intervention. In addition, portions of the client computer
system 214 software itself or mobile playback device 212 resident software/firrnware may be
downloaded or updated from library server 260. The mobile playback device 212 resident
software/firmware is downloaded through client computer system 214. If library server 260 has
an updated or more recent copy of client computer system 214 software or mobile playback device
212 software/firmware, the library server copy is downloaded to replace the outdated version of
the corresponding client computer system 214 software or mobile playback device software 212.
?CA 02265549 l999-03- 10
W0 98/1 1487 PCT/US97/ 16184
15
The software is encrypted, scrambled, and digitally signed in a manner similar to the scrambling
and delivery of the digital information ?les. Changes to the ID list, audio prompts, and other
configuration data for playback device 212 can be downloaded in a manner similar to the
downloading of software updates from library server 260.
The preferred embodiment utilizes three authentication processes to protect the transfer of
information from server 260 to client system 214 and playback device 212. First, a point-toâpoint
authentication protocol is performed whereby the library server 260 must verify that the requesting
client computer system 214 is an authorized client and the client computer system 214 must verify
that the library server 260 is an authorized provider. Secondly, a targeting protocol is performed
whereby the library server 260 utilizes a set of identifiers (i.e. player IDs) for mobile playback
devices 212 authorized to receive the selected download data from library server 260. The mobile
playback device identi?ers are provided by client computer system 214 or are referenced from user
profiles stored on library server 260. In the targeting process, library server 260 formats and
downloads data that can only be read by mobile devices 212 with these identifiers. Thirdly, a
library server digital signature is appended to the downloaded data for use by the mobile playback
device 212 to verify that the downloaded data was originated by an authorized library server.
These three authentication processes of the present invention are described in detail in the
following sections.
PointâtoâPoint Authentication Protocol
The library server 260, client computer system 214, and mobile playback devices 212 each
have a unique veri?cation sequence which is used to verify the authenticity of another system. In
communications between library server 260 and client system 214, both systems alternately act to
(1) request verification of the other system and (2) provide an authenticating response to a
veri?cation request. Communication between mobile devices 212 and client computer system 214
use a similar authentication protocol, as well as realâtime communication between mobile devices
212 and library server 260 via client system 214. This veri?cation sequence comprises a pre-
defined set of bit streams or data structures which are sent by the requesting system (ie. the
system requesting veri?cation) to the receiving system being authenticated (i.e. the respondent) in
a point-to-point transmission. The receiving system must respond to the veri?cation sequence in a
pre-defmed manner by sending particular response bit streams or data structures to the requesting
system. If the appropriate response data from the respondent is received by the requesting system,
the system being verified is considered an authorized system. Conversely, the system being
verified is considered unauthorized if the appropriate response data is not received by the
requesting system prior to a pre-de?ned time-out period. Both systems begin communication by
acting as requesters and respondents in separate veri?cation cycles. Upon completion of these
?CA 02265549 l999-03- 10
W0 98/1 1487 PCT/U S97/ 16184
16
point-toâpoint authentication cycles, further client/server processing only continues if both systems
deem each other to be authorized systems.
In an alternate embodiment, point-to-point authentication is used in a subset of the
communications among library server 260, client computer system 214, and mobile playback
devices 212. In another embodiment, point-to-point authentication is not used and system security
rests on the use of targeting and/or digital signature authentication.
Targeting Protocol
The targeting protocol of the present invention is a means and method for limiting the
playback of digital information content, the adjustment of player configuration data, and the
download of player operating code to a specified player 212/226 or a specified set of mobile
playback devices 212. Each player 212/226 contains a unique player ID 223. The player ID 223
comprises a public player ID and a private player ID. The public player ID is a unique identifier
and serves as a serial number for player identi?cation. The private player ID is used to target data
for individual mobile playback devices 212. Private player IDs are never sent through any
communications link or network path, except during installation. In the preferred embodiment,
private player IDs should be suf?cientlygdiverse, but need not be unique.
Mobile playback devices 212 may be logically grouped together using a Group ID. Digital
information content, software, or configuration data changes may be targeted to a group of mobile
playback devices 212 defined by a group ID. Each player 212/226 includes memory space for
storage of one or more group IDs 225 of which the particular player 212/226 is a member. Each
group ID includes a public portion and a private portion, each of which is equivalent to the public
and private player IDs, respectively. Each group is identified by a uniquely valued public ID that is
not shared with other player or group IDs. Digital information content, software, or con?guration
data can be targeted to a particular group ID in the same way as it would be targeted for a specific
player ID. Mobile playback devices 212 in the same group share the same Group ID. A particular
Group ID is pre-defined as the global group to which all mobile playback devices 212 are a
member. Mobile playback devices 212 may be members of more than one group. A particular
player 212/226 is added to a new group by appending the new group ID to the set of group IDs
225 maintained in the particular player 212/226. The new group ID is appended after the server
260 provides a public group ID and a group key to the player 212/226 via client computer system
214. The player 212/226 generates a private group ID from the combination of the group key and
the mobile playback device's 212 private player ID. As with the private player ID, the private
group ID is never sent through any communications link or network path, except during
installation. In an alternative embodiment, players receive the group private ID directly or by
combining the group key with the players public ID or other known numeric value. In another
?CA 02265549 l999-03- 10
wo 93/1 1437 PCT/US97/16184
17
alternative embodiment, the private group ID is not used in the targeting process and is not
transferred to the player. The group assignment process may be restricted to using real-time
communications between server 260 and the player via client system 214, or it may take place
sometime after group assignments have been downloaded to client system 214. Having described
the player IDs and group IDs de?ned in the present invention, the use of these IDs in the targeting
protocol is described next.
Library server 260 includes a player ID table 266 as shown in Figure 2. Player ID table
266 includes a storage area for private IDs and public IDs. The private IDs are pre-loaded into
player table 266 when a new mobile playback device is installed into the system or when a new
group is established. In another embodiment, ID table 266 is a mathematical function which
converts group or player public IDs. Public player and group IDs are sent by a client computer
system 214 to the server 260 when the client computer system 214 desires to target a particular
player 212/226 or set of mobile playback devices 212 to a particular specified digital information,
software content, or configuration data selection. Digital information selection is made from the
files 262 stored on library server 260. Software or configuration data selection is made from ?les
stored on server 260 or from data generated upon request by server 260. Software content and
configuration data is prepared and scrambled in a manner similar to the authoring process for
digital information content. Once an association is made by client computer system 214 between a
set of targeted public IDs and the associated data to be transferred from server 260, library server
260 creates a targeted header for the selected files. The library management software 261 consults
the public ID to private H) table 266 to locate the corresponding targeted private ID(s). The
targeted header comprises a combination of the descrambling map 322 from the selected files with
the private player IDs corresponding to the targeted mobile playback devices 212. The
descrarnblin g map 322 is thereby encrypted using the secret IDs of the targeted mobile playback
device(s) 212. This targeted header is linked with the corresponding digital information or
software content of the selected file in a network transport ready data block. A digital signature is
applied to the data block as described below in connection with the data signature protocol.
Transport integrity data (such as the use of checksums or cyclic redundancy check) is applied to
the data block and the data block is sent to the client computer system 214 via network 240.
Because the data block can only be unscrambled using the corresponding descrambling block 322
in its header and because the descrambling block 322 was combined (i.e. encrypted) with a private
ID known only by the targeted mobile playback device(s) 212, only the targeted mobile playback
device(s) 212 will be able to unscramble and read the data block. The selected digital information,
software content, and configuration data is thereby targeted to a particular set of mobile playback
devices 212.
For small groups of mobile playback devices 212, each targeted header of a digital
?CA 02265549 l999-03- 10
W0 98/11487 PCTlUS97/ 16184
V 18
information file may contain a plurality of descrarnblin g maps, each associated with a different
player 212/226. In this manner, multiple mobile playback devices 212 can read a single file 220
stored on the client computer system 214.
A person of ordinary skill in the art will note that alternative methods of targeting exist. In
an alternative embodiment, library server 260 uses the targeted recipient's private player 212/226
identifier or the targeted group's private group identifier to generate scrambling map 316.
Descrambling map 322 is not stored with the file as it is already known by the recipient player or
group. This method targets content to a single player 212/226 or group and achieves the identical
result of preventing unauthorized playback of content.
In another alternative embodiment, library server 260 does not scramble the digital
information content or uses a known key to scramble the digital information content. In this
embodiment, descrambling map 322 is unnecessary and is not stored with the file. Either the
public or private player 212/226 identi?er can be stored in the header for targeting identification
purposes. Upon receipt of data from library server 260, the player 212/226 checks if its player
212/226identif1er or group identi?er is included in the header. This method assumes unmodi?ed
mobile playback devices 212 and achieves the identical result of preventing unauthorized playback
of content.
In another alternative embodiment, the player IDs for the targeted mobile playback devices
212 are sent to the library server 260 by the client computer system 214 when the user registers
with the library server 260 to obtain the user's client ID. In this alternative embodiment, these
player IDs are stored on the library server 260 in a user profile. In this embodiment, the library
server 260 manages the player IDs for the targeted mobile playback devices 212.
Digital Signature Protocol
The third authentication protocol used in the present invention is the digital signature
protocol. For selected data blocks generated by library server 260 and downloaded to a client
computer system 214, library server 260 uses its private library key 263 to apply a digital
signature to the data block. The digital signature comprises a known bit suing or data pattern
which is combined with the data in data blocks that are downloaded from library server 260 to
client computer system 214. The library server 260 may perform this operation on all the data
blocks or a selected subset of the data blocks. After a data block is downloaded to a player
212/226 through a client computer system 214, the player 212/226 can retrieve the digital
signature applied by the library server 260 using a public server key known to the player 212/226.
The player 212/226 can thereby verify that the data block originated with an authorized library
server 260. The public server key is also known to client computer system 214, which can
perform the identical operation to verify that the data block originated with an authorized library

sewer 260. In this embodiment, library server 260 performs signatures on the content. A person
of ordinary skill in the art would realize that the signatures may also be performed on the digital
information by authoring system 280. The signatures may also be performed in a multiple step
process shared by authoring system 280 and library server 260.
In an alternate embodiment, digital signatures are applied to downloaded material by a
trusted client computer system 214. In another alternate embodiment, digital signatures are not
applied to downloaded material and system security rests on the use of targeting and/or pointâto-
point authentication.
Downloading Digital Information Content, Software Updates, or Con?guration Information From
me Client Computer System to the Mobile Playback Device
In a first step, the client computer system 214 and the mobile device use the point-toâpoint
authentication protocol described above to verify that an authorized mobile playback device 212 is
communicating with an authorized client computer system 214. If this is the case, the mobile
playback device 212 transmits its memory map to the client computer system 214 via the mobile
device interface 221. A table of contents defining the available digital information files 220 and
player configuration profiles resident in client computer system 214 is displayed along with the
mobile playback device 212 memory map for a user of client computer system 214. The user
selects which files 220 of client computer system 214 should replace portions or segments of
speci?ed mobile playback device 212 memory as defined by the mobile playback device 212
memory map. Altemately, client browser 219 can be configured to automatically perform this
selection process. In either case, the user is prevented from selecting digital information content
larger than the available memory of playback device 212. In addition, control software and/or
configuration data for playback device 212 may be automatically updated by client computer 214.
The speci?ed digital information files 220, associated headers, operating code, or con?guration
data are thereafter downloaded into mobile playback device 212 memory. The mobile playback
device 212 uses checksums to verify the integrity of the download. The mobile playback device
212 uses the server public key 215, the header, and the digital signature to authenticate the
download as described above. The header descrambling map is used by targeted mobile playback
devices 212 to unscramble the downloaded data. In other embodiments, mobile playback device
212 may unscramble the downloaded data and/or decompress the downloaded data before
authenticating the signature. Each segment of the digital information content may be
independently authenticated and validated using any of the techniques described above. Digital
information prompts on the mobile playback device 212 guide the user to the desired portion of the
?CA 02265549 l999-03- 10
W0 93/1 1437 PCTIUS97/16184
20
downloaded digital information content as speci?ed by the table of contents residing in the header
of the downloaded data. The user may preview selected portions of the digital information content
by selecting a preview option. The preview option plays a predetermined portion of a selected
digital information program. Upon selection of a particular digital information program, the
selected digital information program is played for the user after the mobile playback device 212
converts the digital information content into sound or displayable imagery which is played through
an audio output means or displayed on a display device.
The software player 226 of client computer system 214 may also receive digital
information content in approximately the same form as the digital information content downloaded
to the mobile playback device 212; however, the digital information content for the software player
226 does not need to be downloaded to the software player 226. The software player 226 has
direct access to the digital information content; because, it shares memory and/or disk storage
space with the client computer system 214. Therefore, there are no downloading or memory map
concerns. In the same manner as the mobile playback device 212, the software player 226
performs digital signature verification, verification of checksums, and receiving targeted
information. In an alternative embodiment, software player 226 may use a communication
protocol similar to that of mobile playback device 212 when receiving digital information content,
configuration information, and dynamically downloaded software.
Figure 4 illustrates an alternative embodiment of the present invention. As shown in Figure
4, authoring system 280 can support a plurality of library servers 260. Each library server can be
con?gured to support a speci?c type of digital information content. In the same manner described
above, the client computer systems 214 access network 240 and obtain digital information content
from any of the library servers 260 after performing the authentication process described above.
Authorization server 270 is provided for this purpose. The configuration illustrated in Figure 4
provides a more distributed architecture thereby dispersing the load across several server
platforms. A site with many client computer systems 214 may have its own library server 260 to
reduce demand on network 240. This architecture scales well as the number of client computer
systems 214 grows and the content provided by the library server 260 grows.
Figure 5 illustrates another embodiment of the present invention except the library server
461 has been implemented as a plurality of separate processes or tasks 460 running concurrently
on a single library server platform 461. Each library server process 460 services requests for
access to its corresponding portion of the digital information content. This content is created using
authoring system 280 in the manner described above. The authorization server 270 is used to
validate the links between the client computer systems 214 and the library server processes 460.
The con?guration illustrated in Figure 5 is advantageous in that the convenience of a single server
is maintained while the scalability of multiple libraries is also supported.
?CA 02265549 l999-03- 10
W0 98/1 1487 PCT/US97/16184
21
This concept can also be used for the authoring and authorization servers 280 and 270,
respectively. As shown in Figure 6, the authoring system 280 and the authorization server 270 is
implemented on a single platform 685 as authoring process 680 and authorization process 670.
These processes perform the same functions as described above, except the implementation
provides the convenience of a single server and the scalability of multiple processes for the
authoring and authorization tasks.
Figure 7 illustrates yet another alternative embodiment wherein the client computer systems
214 include a local library 710. The local library 710 provides a local storage area and library
access control functionality which provides access to a subset of the archived digital information
from library server 260. In the manner described above, the user of a client computer system 214
identifies the titles or items of digital information in library server 260 that the user wishes to
access. In the preferred embodiment, these content selections are transferred to a client storage
area 220 (as shown in Figure 2) for subsequent downloading to mobile playback device 212. The
embodiment shown in Figure 7 expands upon the client storage area 220 and creates a local library
710. The local library 710 is used for storage of selected content; but also for searching, sorting,
categorizing, and abstracting the locally stored content. The local library 710 allows a client
computer system 214 to maintain a small subset of the full library which may be used to create
custom collections of content in a variety of user selected con?gurations. Client systems 214 may
be permitted to access the contents of local libraries 710 on other client systems 214. In a related
alternate embodiment, library server processes 460 may also reside on selected client systems 214.
This embodiment allows client systems 214 to browse and purchase content that is scrambled,
targeted, and delivered from library server process 460 executing on a locally positioned client
system 214. By maintaining the library locally, a portion of the network access and transfer
overhead is eliminated.
Figure 8 illustrates another alternative embodiment of the present invention wherein the
client computer system 214 is eliminated and the mobile playback device 212 is connected directly
to the network 240 through network interface 810. In the preferred embodiment, the mobile
playback device 212 is a minimal capability device primarily dedicated to playing audio files or
displaying visual images or text on a display device. The mobile playbackdevice 212 is minimally
configured to retain its light-weight, low cost, and readily mobile features. The preferred
embodiment does not therefore include the use of a portable personal computer or laptop
computer; because, such devices typically do not meet the light-weight and low cost constraints of
the preferred mobile playback device 212. However, the minimal mobile playback device 212 may
be augmented to add network interface 810 which comprises a conventional hardware connector,
hardware buffers and controllers, and firmware support for a particular conventional network
protocol. For example. the mobile playback device 212 may be augmented with an integrated
?CA 02265549 l999-03- 10
W0 98/ 11487 PCT/US97l16184
22
modem that includes a telephone jack with which the playback device may be connected to a
telephone network. It will be apparent to those of ordinary skill in the art that network interface
810 may be implemented in a low cost and lightâweight device such as mobile playback device
212. Because the client system browser 219 would not be available in the alternative embodiment
shown in Figure 8, a simpli?ed user interface may be provided in firmware or other non-volatile
memory of mobile playback device 212 with which the user may select items of digital information
for download and playback from library server 260. As described above, the authentication
process to validate the link between the mobile playback device 212 and the library server 260
must also be performed prior to user access to the library server 260 content. Alternatively, a client
system 814 coupled to network 240 may be provided to support client browser 219 and thereby
enable selection of items of digital information for download and playback from library server 260
directly to any of the mobile playback devices 212. Client systems 814 may support local storage
of digital information, software, and configuration data in a form similar to storage space 220 or
local library 710. In addition, a more simplified implementation of network interface 810 may be
designed to communicate via network 240 to client system 814 instead of library server 260.
In another alternative embodiment of the present invention, digital information
programming selections are made using the client computer system 214 and library server 260 as
described above; however, the selections are delivered on mass storage medium 241. Mass
storage medium 241 represents any of a variety of conventional mass storage technologies
including CD-ROM, PCMCIA cards, DVDs, ?oppy disks, removable hard drives, digital
magnetic tape, optical cards, ?ash memory or other optical, magnetic, electronic, or
semiconductor memory devices. Upon selection by a user of a client computer system 214,
selected programming is targeted and scrambled as described above and transferred to a selected
mass storage medium 241 and mailed, hand-delivered, or held for pickup by the user. Once the
user takes physical possession of the selected mass storage media 241, the selected programming
may be read from the mass storage medium 241 by the client browser 219 and thereafter
transferred to the mobile playback device 212 as described above. Figure 9 illustrates another
embodiment of the system that does not include the use of client computer 214 to transfer data to
mobile playback device 212. Kiosk 910 consists of a computer system such as the one described
above in Figure 1. Kiosk 910 is a publicly accessible unit that can perform browse, content
purchase, and download functions in a manner equivalent to a client computer system 214. The
kiosk 910 is special because it contains its own library server for fast local access and download
of content. Kiosk 910 contains a mobile device interface 221, a special version of client browser
219, and local library server process 460. Kiosk library server process 460 has local storage of
scrambled and compressed digital information files 262. These compressed information ?les 262
originate from remote authoring system 280 and may be delivered via physical transport of mass
?CA 02265549 l999-03- 10
W0 98/11487 PCT/U S97/ 16184
23
storage media 241 or via distribution network 240. A customer operates client browser 219 to
browse, select, and purchase digital information ?les that are delivered to the customer's mobile
playback device 212. Authentication, targeting, and download processes are performed within the
kiosk by library server process 460 that is connected to remote authorization server 270 over
network 240. In a related embodiment, ?gure 7 shows a client system 214 with local library 710
that can be converted into a kiosk with functionality similar to kiosk 910. In this system, a special
version of client browser 219 provides the same user functionality as the previous kiosk
embodiment.
An alternate embodiment of the system uses a common communication network to connect
all system components. In Figure 10, network 240 is directly coupled to client system 214 and
814, network interface(s) 810, library server(s) 260, authorization server 270, and authoring
system(s) 280. One of ordinary skill in the art will realize that network 240 can also be segmented
into a number of independent networks or communication links without changing the functionality
of the system.
Thus, a method and apparatus for implementing a computer network based digital
information library system employing authentication and encryption protocols for the secure
transfer of digital information library programs, software, and configuration data to a client
computer system and a mobile digital information playback device removably connectable to the
client computer system is disclosed. Although the present invention has been described with
respect to speci?c examples and subsystems, it will be apparent to those of ordinary skill in the art
that the invention is not limited to these specific examples or subsystems but extends to other
embodiments as well. The present invention includes all of these other embodiments as specified
in the claims that follow.
