Description

METHOD OF SALES AND ADVERTISEMENT USING VOICE AND IMAGE OF FAMOUS PERSONS, AND SYSTEM THEREOF

TECHNICAL FIELD

The present invention relates to a method and system for advertising and selling a commodity, and more particularly to a method and system for advertising and selling a commodity using a celebrity' s voice and image through the internet .

BACKGROUND ART Before introducing an electronic commercial transaction, persons touch or look at a commodity in a market to purchase the commodity. However, after introducing the electronic commercial transaction, persons photograph a corresponding commodity by a camera to obtain an image thereof . They scan the image by a scanne . They load the scanned image at a suitable location of a web page screen using a graphic tool and add a suitable description to the loaded image. They provide a corresponding web page for the commodity to a web browser of a user computer whichuses an electronic commercial transaction through the internet by using a web server. In the prior art, a required technique is not to reduce a transmission speed of a server by compressing and transmitting most of the data to display the image, that is, a static image. A graphic image file form which a web protocol supports includes a Graphics Interchange Format (GIF) having a file extension "gif" and a Joint Photographic Experts Group (JPEG) having a file extension "jpg". However, definitions of the GIF and JPEG images are low. When increasing pixels in order to compensate for the low definitions, the image definitions become lower or the images are broken. When increasing the amount of data in order to improve equality of the image, a greater load is applied to a server which reduces a transmission speed. Unlike the JPEG which compresses a static image, a Moving Picture Experts Group (MPEG) compresses moving picture video data which continuously changes according to time and transmits information through a code expression. However, in the MPEG, since much data are required to transmit information, the transmission speed is low. The conventional commodity advertising and selling method displays a commodity image and a text explaining a commodity in an electronic commercial transaction on a web browser of a client computer. Thus, a commodity advertising and selling method on the internet capable of overcoming the conventional commodity advertising and selling method and attracting purchasers is required.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, this invention will be described in detail with reference to the drawings .

FIG.1 is aview for showing a configuration of an apparatus for loading a celebrity's image and voice according to an embodiment of the present invention.

The image and voice loading apparatus includes a client computer 1, an internet 2, a server computer 3, audio and video ZIP programs (AVZIPs) 4a and 4b, an image database 5, and a voice database 6. The client computer 1 and server computer 3 are connected to the internet 2. Each of AVZIPs 4a and 4b serves as a compressor. AVZIPs 4a and 4b are connected to each other in the server computer 3. The image database 5 is connected toAVZIP4a throughaLANline, andavoice database 6 is connected to AVZIP 4b through a LAN line.

The client computer 1 receives a user's selection with respect to a voice and an image of a celebrity. The client computer 1 transmits the user' s selection to the server computer

3 through the internet 2. When a decompression program file together with image and/or voice files compressed by the server computer 3 are transmitted and loaded to the client computer

1, the compressed image and/or voice file is automatically removed according to the decompression program file by a Real audio player or a Windows media player included in a web browser of the client computer 1 so that the user can look at or listen to the image and/or voice. The real audio player or window media player is included in a web browser of the client computer 1.

Since the internet 2 is now used all over the world, that description is omitted.

The server computer 3 receives a user's selection with respect to an image and/or voice of a special celebrity, for example, a character image. The server computer 3 controls the image or voice database 5 or 6 to transmit an image and/or voice corresponding to a selected character image to the server computer 3. When the server computer 3 receives compressed image and/or voice files transmitted from the database 5 or 6 and compressed in the AVZIP 4a or 4b, the server computer 3 inserts an automatic compression program file into the compressed image and/or voice files and transmits them to the client computer 1 through the internet 2. Thus, when the compressed files are loaded on the client computer 1, users can look at an image and/or voice without using a separate compression program.

A real image or an animation image (hereinafter, the real image or animation image is called an "image") which is not compressed is stored in the image database 5. When the image database 5 receives a command from the server computer 3 to transmit the selected image to the server computer 3, the image database 5 transmits a corresponding image to the AVZIP 4a.

The AVZIP 4a is a compressor including an AVZIP program for performing an audio and video compression technique which an inventor of the present invention has developed. A compression rate of the AVZIP program is two through three times that of another compression program. The AVZIP program will be described later. When a corresponding image from the image database 5 is transmitted to the AVZIP 4a, the AVZIP 4a compresses the image in an optimal state to make and transmit a compressed file to the server computer 3.

A celebrity' s voice which is not compressed is stored in the voice database 6. When the voice database 6 receives a command to transmit a selected voice from the server computer 3, the voice database 6 transmits a corresponding voice to the AVZIP 4b.

TheAVZIP 4b includes a compressorhaving anAVZIPprogram. When a corresponding voice from the voice database 6 is transmitted to the AVZIP 4b, the AVZIP 4b compresses the voice in an optimal state to make and transmit a compressed file to the server computer 3.

The reason to separately form image and voice databases is to reduce time to a minimum while responding to a client computer when users select a celebrity's image or character i age .

When the server computer 3 receives compressed image and/orvoice files fromthe AVZIPs 4a and 4b, the server computer 3 inserts and transmits an automatic decompression program into the compressed image and/or voice files to the client computer 1. The compressed image and/or voice file is automatically removed according to the decompression program file by a real audio player or a window media player included in a web browser of the client computer 1 so that the user can look at or listen to the image and/or voice together with background music. The real audio player or window media player is included in a web browser of the client computer 1.

FIG.2 is aview for showing a configuration of an apparatus for loading a celebrity' s image and voice having an image chat function according to an embodiment of the present invention.

According to the apparatus, a preferred customer in the shopping site is selected andhas an image chat with a celebrity. That is, the preferred customer is selected based on a coe ficient of utilization of the shopping site and purchase money amount and has the image chat with an invited celebrity who the preferred customer is favorably disposed toward the celebrity during a customer service situation. A conventional image chat has disadvantages that an image is not continuously outputted and image equality is not clear . The present invention improves image equality using an AVZIP compression technique by means of the system shown in FIG. 1.

Hereinafter, a difference between the apparatus of FIG. 1 and the apparatus of FIG. 2 will be explained.

The client computer 1 and an AVZIP 4c are connected to the internet 2. Server computers 3a and 3b are connected to each other in the AVZIP 4c. A voice database 7 is connected to the server computer 3a. An image database 8 is connected to the server computer 3b. An AVZIP 4d is connected to the image database 8. A celebrity computer 9 is connected to an AVZIP 4d.

The celebrity computer 9 receives an image and/or voice . The AVZIP 4d is installed on an LAN line . The AVZIP 4d compresses and stores the image and/or voice received by the celebrity computer 9 once in the image database 8. Then the AVZIP 4c compresses and transmits a program compressed by the AVZIP 4d once again to the client computer 1 so that a user can have a chat with a celebrity with natural image quality and a clear voice.

A conventional image chat is mainlyperformedvia an image and a character. Capacities of the image and a voice are big, and a compression technique is defective in the conventional image chat. However, according to an AVZIP of the present invention, an image and voice chat is performed simultaneously using the image and voice having a good compression rate.

Since large capacities of files are divided and transmitted into small units, the transmission speed is high.

When the transmission is completed, the divided small units are again recovered to one file so that the user can look at and listen to the image and voice. Since the image and voice should be transmitted at real time, they can be quickly transmitted by compressing the AVZIP twice.

FIG. 3 is a view for showing flows of data which are used in an embodiment of the present invention.

A database 10 is connected to voice and image databases 7 and 8 and supports one MS-SQL to the voice and image databases 7 and 8. The database is stored to divide an image and a voice When calls of users are generated, an AVZIP compresses and transmits each file stored in the database 10 to a server. The server converts and transmits the file from the AVZIP into a format which a user can use.

FIG. 4 shows a service screen for displaying on monitors of users according to an embodiment of the present invention.

When auser clicks a celebrity' character, amovingpicture screen is displayed. When the user clicks a celebrity' name under the character, a voice is ouputted. When the user clicks a photograph of a commodity, the moving picture screen is outputted together with a voice. A loading time of the moving picture screen is a little longer than that of the voice. When a moving picture is displayed, simultaneously background music is outputted.

A detailed image view button serves to show an enlarged photograph of a commodity. A shopping basket button is located by the detailed image view button. Auser determines to purchase a commodity by pushing a shopping basket button.

FIG.5 shows a screen that a window media player executes when a user clicks a celebrity's character on a service screen shown in FIG. 4. FIG. 5 shows a screen in which a singer UHM

Jung-hwa' s moving picture describes a commodity. As the singer

UHM Jung-hwa' s moving picture moves, the singer UHM jung-hwa' s voice is outputted together with background music. After a user listens to the description, the user intends to purchase bypushing a shoppingbasket button. As auserpushes the shopping basket button, the screen automatically moves to a shopping basket page of the site to help a user' s purchase. Whena purchase is determined in that manner, a purchasing rate with respect to the singer UHM Jung-hwa increases.

When a moving picture of each celebrity describes the commodity, an estimate and a level with respect to a purchasing rate are displayed at the upper left and right ends of the moving picture. Visitors are users who look at a celebrity's moving picture, and purchasers are users who actually purchase commodities among the visitors. A purchasing rate is a value obtained by dividing visitors and purchasers into a hundred parts. The level indicates that a purchasing rate with respect to a celebrity character loaded on the home page is the sixth level . By displaying levels of each celebrity character, users who like the celebrity are induced by a competitive spirit to support a purchase rate .

FIG. 6 is a view for showing a screen having a total order with respect to a purchasing rate of each celebrity character when a user clicks a total order view button. When a user wants to know an order of a purchase rate with respect to the total celebrity characters, the user pushes a total order button on a screen shown in FIG. 4 or FIG. 5.

FIG.7 is a flow chart for illustrating amethod for loading a celebrity's image and voice according an embodiment of the present invention.

In step SI, a user starts a client computer 1. In step S2, the user accesses a site of a server computer 3 using a client computer 1 through the internet 2. The client computer 1 checks whether the access operation is completed (step S3) .

When the access operation is not completed in step S3, the routine returns to step S2. When the access operation is completed in step S3, the client computer 1 requests image and/or voice databases 5 and/or 6 to synchronize (step S4) . In step S5, the image database 5 produces and transmits a copy of a database of an image to a first AVZIP 4a. The first AVZIP 4a compresses the copy of a database of an image (step S6) . The first AVZIP 4a checks whether the compression operation is completed in step S7. When the compression operation is not completed in step S7, the routine returns to step S6. When the compression operation is completed, the routine goes to step Sll.

On the other hand, in step S8, the voice database 6 produces and transmits a copy of a database of a voice to a second AVZIP 4b. The second AVZIP 4b compresses the copy of a database of a voice (step S9) . The second AVZIP 4b checks whether the compression operation is completed in step S10. When the compression operation is not completed in step S10, the routine returns to step S9. When the compression operation is completed, the routine goes to step Sll

In step Sll, the first AVZIP 4a and the second AVZIP 4b transmit the compressed copies of databases of an image and a voice to the server computer 3, respectively. In step S12, the client computer 1 checks whether the transmitting operations are completed. When the transmitting operations are not completed, the routine returns to step Sll. When the transmitting operations are completed in step S12, the server computer 3 inserts an automatic decompression program into the compressed copies of databases of an image and a voice, divides the compressed copies of databases of an image and a voice, and prepares transmissions of the compressed copies of databases of an image and a voice (step S13) . In step S15, the server computer 3 transmits the prepared copies to the client computer 1 through the internet 2.

FIG.8 is a flowchart for illustrating a method forpurchasing a commodity on an internet according to an embodiment of the present invention.

In step S21, a user starts a client computer 1. The user looks at commodity information and a moving picture of a celebrity related thereto (step S22) , and determines whether to purchase a commodity corresponding to the commodity information (step S23) . When it is determined in step S23 that the user does not purchase the commodity, the routine returns to step S22 and the user selects a moving picture and a voice of a celebrity with respect to a next commodity. When it is determined in step S23 that the user purchases the commodity, the user compares and searches similar kinds of commodities with one another and selects and puts a desired commodity in the shopping basket (step S24) . In step S25, the user inputs an identification and a password for authorization as a member. In step S26, the user inputs detailed information of a place at which the commodity will be delivered. In step S27, the user determines a payment method. When the user wants to pay using a credit card, the user inputs the number of the credit card. The server computer 3 finally asks whether the user wants to purchase the commodity (step S28) . When the user pushes a purchase cancellation button in step S28, the routine returns to step S24. When the user pushes a purchase button, the purchasing operation is completed and the overall operation finishes .

In the flow chart in FIG. 8, step S23 can be omitted. In such a case, after step S22 , step S24 is performed to compare and search similar kinds of commodities with one another.

FIG. 9 is a flow chart for displaying a purchasing rate and a purchase level by characters of a celebrity.

In step S31, a user starts the client computer. The user accesses a home page using a client computer l(step S32) and selects a purchasing commodity from the home page (step S33) .

The user selects UHM Jung-hwa character and listens to a description of a commodity (step S34) and determines whether to purchase a commodity (step S35) .

In step S36, the server 3 asks the user whether the user want to purchase the commodity. When the user does not want to purchase the commodity, the routine returns to step S33.

When it is judged in step S36 that the userwants topurchase the commodity, the user clicks a shopping basket (step 37S) . Accordingly, a database of the character is ope (step S38) , and a commodity purchasing count with respect to the character increases by 1 (step S39) . The number of visitors is counted up(ste S40) . The number of purchasers is counted up (step S41) . A purchasing rate is calculated (step S42) . A purchasing level is controlled (step S43) . A database of the character is closed (step S44) . New information is displayed on a monitor as shown in FIG. 5 (step S45) . The overall operation finishes (step S46) .

An effective purchasing determination is provided to a user who is not sufficiently satisfied with a commodity description of a conventional electronic commercial transaction or a user who is bored with a similar conventional electronic commercial similar method.

A user can look at a description of a celebrity character and can improve the comprehensive aspects for a commodity. A user takes an interest in the electronically commercial transaction and continues to stay in the home page. Usefulness and novelty remain in a user' s memory so that the user continues to search the home page. It has an effect upon an embodiment of a site which is the core of an electronically commercial transaction.

As many users access the home page, purchases of the commodities increase and sales revenue increases.

Hereinafter, an AVZIP which is an image and voice compression program according to an embodiment of the present invention will be described.

SUMMARY OF AVZIP DIGITAL IMAGE COMPRESSION TECHNIQUE

As the 21st century multimedia period has arrived, digitalization of information is suddenly required. Accordingly, a necessary information compression technique has been developed for an application field thereof. The development of the information compression technique has resulted in events whichwere impossible in the following fields to now be possible. In an information communication field, a multimedia communication is available. The multimedia communication such as an image is available at a cheap fee such as a telephone. Also, in an information storage field, multimedia information such as an image can be recorded in a cheap storage medium. An occupying amount necessary to record the multimedia information can be reduced.

As mentioned above, when using information compression, the multimedia information can be transmitted using a cheap medium which had not been thought until now. That is, in order to transmit the multimedia information, a new media infrastructure should be improved to meet a development of the information compression technique. Accordingly, the development of the information compression technique has accelerated international standardization and provided an environment which can mutually use the multimedia information in a wide field including communications, broadcasting, household electric appliances, and computers. Mutual use of the multimedia information is called "interoperability".

Table 1

INTERNATIONAL STANDARD OF MULTIMEDIA CODING

DCT: Discrete Cosine Transform

MC: Motion Compensation

Peoples are propelling studied development of coding a multimedia such an MPEG and persons in a network field are aiming at an open system to place the focus on the interoperability. A Joint Photographic Coding Experts

Group (JPEG) and an MPEG are lower level organizations of an international organization for standardization (ISO) . Anumber such as ISO xxxxx is added in a formal recommendation. Also,

H.261, H.221, G.721, G.722, and G.728 are recommendation numbers determined by International Telecommunication

Union-Telecommunication Standardization Sector (ITU-T) . The

ISO and ITU-T are advancing a standardization related to a multimedia element technique. Table 1 indicates an international standard for multimedia coding. The above mentioned international standardized compression method has been applied to a peace preservation and guard field. However, since an image compressionrate has an influence on a competitive power of a commodity, development of a compressionmethod having high efficiency is required. It is not necessary to use a standardized compression method in order to secure stored image information.

DIGITAL AVZIP IMAGE COMPRESSION METHOD

As mentioned above, an image compression technique is a very important technique in the multimedia times . The image compression technique is more important in the peace preservation and guard field connected directly with the competitive power of a commodity than any other fields.

Generally, an analog moving picture signal of a camera is converted into digital information. The digital information is stored in a frame memory. The frame memory is a memory which stores one screen. The stored digital information is decomposed in a pixel unit. A pixel is a basic unit of image information which forms a screen. For example, one pixel is indicated as 352 width pixels x 240 length pixels . Each pixel has a luminance and a color difference, and the luminance and the color difference compress the image information by the following four methods .

(1) Aduplication of a color sensitivity spectrum is deleted. That is, 24 bit information for a pixel is converted into YCbCr 12 bit to compress information.

(2) Since image values between adjacent pixels are almost similar, an information is compressed by a spatial correlation in a screen.

(3) The information of a previous screen is remembered. The information is compressedbya time correlation in a screen by obtaining a difference between the previous screen and a current screen.

(4) When a coding operation is performed by the two methods, the information is compressed by using different generation probabilities of codes. The four compression methods are used together with one another. Such a method is called a hybrid coding. An AVZIP uses the hybrid coding.

The greatest advantage of anAVZIP is that theAVZIP receives an image at long range at real time and actively grasps and deals with a situation.

Since the AVZIP can store an image having high quality for a longer time by processing many frames at the real time by a high compression rate, the cost is reduced and it can be compatible with a wavelet based technique.

The technique is used on the assumption that a conventional

MPEG decoder is used.

Hereinafter, a principle of an AVZIP according to the present invention will be described.-

An initial image is divided into one-third at a time using a wavelet operation method. Only low pass band surface is processed by an MPEG decoder and only part being in motion is processed using a motion compensation such as an MPEG. When a wavelet is used, parts being in motion in the divided screens are all identical with one another. Accordingly, the difference is between the wavelet operation method and the conventional

MPEG motion compensation, such that the wavelet operation method can detect parts being in motion in different high pass band surfaces based on a motion of a low pass band surface .

A motion of a low pass band surface is coded by using a DCT, and a different high pass band surface is coded by a zero-tree coding by using relationships between bands. When using 3 divisions instead of 4 divisions, a main wavelet converting time in an MPEG using a wavelet in the 3 divisions can be reduced one-fourth more than that in the 4 divisions and a processing time of a motion compensation therein can be reduced.

An AVZIP technique according to the present invention will now be described referring to FIG. 10a through FIG. 12. In the conventional MPEG technique, a total screen is pressed by an MPEG technique. However, in the AVZIP technique according to the present invention, only low pass band surface is MPEG-processed by using a wavelet technique. According to the AVZIP technique, a time for searching motion in the low pass band surface using 3 divisionwavelet is reducedone-fourth more than the conventional MPEG (Since motion in a low pass band surface is identical with that in a high pass band surface, it is not necessary to search a motion in the low pass band surface) . Since thehighpassbandsurface is codedbya zero-tree codingmethodbyusing relations betweenhighpass band surfaces, the number of coded bits can be reduced.

After a motion in the low pass band surface is searched, only part being in motion is discrete cosine transformed (as in the conventional MPEG) and a bit is produced by using a Huffman coding. A data stream is formed by coding and combining all low and high pass band surfaces.

The restoration is oppositely performed, i.e., afterthe low pass band surface is Huffman coded, zero-tree coded, reversely discrete cosine transformed, reverse motion compensated, and added to parts being in motion. Then a reverse wavelet operation with respect to the low pass band surface is performed to restore the original image.

According to the present invention, after an image is divided into 3 by a wavelet, one division surface is processed by an MPEG and the remaining surfaces are zero-tree coded. When compared with the conventional MPEG technique, the technique according to the present invention is the first . Since the image is divided into 3 instead of 4, a wavelet operating time is reduced one-fourth. Also, as shown in FIGs. 10a through 10c, since one pixel in one surface becomes to be identical with two pixel, motions in three surfaces become twice as shown in FIG. 11. INDUSTRIAL APPLICABILITY

An AVZIP technique of the present invention provides a possibility of a security system by using a wavelet . When considering utility of the wavelet, the AVZIP technique is expected to be compatible with the wavelet. Since the AVZIP technique forms a screen of high quality and increases a compression rate, it can store an image of high quality for a longer time. Since parts which are low-pass-filtered by a wavelet are used in an MPEG, noise of the image is removed. Also, the present invention is easily compatible with the conventional VCR system. Accordingly, as a conventional system changes, additional cost is low. FIGs. 13a through 13c show compared results between a file compressed by the AVZIP technique and a file compressed by a JPEG.

Since the conventional compression technique is performed by software encoding in a system, it is limited to a real time compression frameper seconddue to a limitationof aperformance of a CPU. An ASIC which embodies a compression algorithm using an AVZIP has been developed. The ASIC supports a camera having sixteen channels and can process thirty frames per second in 720x480 resolution. The AVZIP can widely be used in a DVR, a video edit and capture system, a remote CCTV system, a digital camera, and a digital camcorder.

Also, the systems according to the present invention efficiently accelerate a purchase decision by a user who many think a description of a commodity of a conventional electronic commercial transaction is insufficient and a purchase decision of a user who is bored with a similar electronic commercial transaction.

A user can look at a description of a celebrity character, thereby improving the comprehensive aspects of a commodity.
