[0007] Additional objects, features and advantages of the various aspects of the present invention will become apparent from the following description of its preferred embodiments, which description should be taken in conjunction with the accompanying drawings .
BRIEF DESCRIPTION OF THE DRAWINGS [0008] FIG. 1 illustrates a block diagram of a system including an apparatus for providing concurrent viewing of Internet information to remote communication session participants, utilizing aspects of the present invention. [0009] FIG. 2 illustrates a flow diagram of a method for providing concurrent viewing of Internet information to remote communication session participants, utilizing aspects of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [00010] Fig. 1 illustrates a block diagram of a system 10 including a server computer 30 providing concurrent viewing of Internet information, such as Internet website information, retrieved from remote server computers, such as remote server computers 41, 42 and 43, to remote communication session participants utilizing remote client computers, such as remote client computers 21, 22 and 23, via the Internet 50 during a communication session, such as an Internet relay chat (IRC) session or a conference call using Voice Over Internet protocol (VoIP) .
[00011] The server computer 30 sponsors or coordinates the communication session between the remote communication participants. It is programmed to provide controlled access to the communication session. Access is typically controlled through an user identification code procedure and/or a communication session identification code. The server computer 30 is also programmed to designate one of the participants as the leader of the session. Initially, the first participant to join the communication session will be designated the leader. Leadership may subsequently be passed to another participant through a hand-off procedure, or a first-in, first-out protocol as the then current leader logs off the communication session.
[00012] The computer server 30 is further programmed for receiving Internet requests, such as Internet addresses or Universal Resource Locators (URLs) and hypertext link requests, from the remote client computers through the Internet 50, retrieving Internet information, such as Internet website information, corresponding to the Internet requests from remote server computers through the Internet 50, and directing the retrieved Internet information through the Internet 50 to the remote client computers so as to provide concurrent viewing of the retrieved Internet information to the remote communication participants. Only Internet information corresponding to Internet requests from the leader are retrieved in order to avoid contention. [00013] Fig. 2 illustrates a flow diagram of a method for providing concurrent viewing of Internet information to remote communication session participants. In 201, a communication session is initiated by a first participant specifying the URL of the server computer 30 on his remote client computer, logging on to the system with his user identification code and password after making a connection, and specifying a prespecified or user defined communication session indicator. In 202, subsequent participants join the communication session by also specifying the URL of the server computer 30 on their remote client computers, logging on to the system with their user identification codes and passwords after making connection, and specifying the same communication session indicator as the first participant. By verifying user identification codes, passwords and communication session indicators, the server computer 30 provides controlled access to the communication session for the remote communication session participants. [00014] In 203, the server computer 30 designates a leader among the remote communication session participants. Since the first participant is initially designated as the leader, 203 precedes 202 the first time a leader is designated by the server computer 30. Subsequently, however, leadership may be passed between participants using a hand-off procedure wherein the then current leader passes leadership to another participant. Alternatively, leadership may be passed on to another participant selected by the server computer 30, if the then current leader logs off without handing off his leadership and before the communication session is over, as indicated by all participants having logged off. In this case, the server computer 30 designates the new leader using a first-in, first-out protocol wherein the earliest participant still logged on to the communication session is selected by the server computer 30. [00015] In 204, the server computer 30 receives URL and hypertext link requests from remote communication session participants. In 205, the server computer 30 retrieves Internet website information corresponding to the URL and hypertext link requests of the leader. In 206, the server computer 30 directs the retrieved Internet website information to all remote communication session participants so as to provide concurrent viewing of the Internet website information to the remote communication session participants. [00016] In one example of the method, a first participant logs on to the system and specifies a prespecified communication session indicator such as "shopping for computers." Subsequent participants also interested in that subject, log on and specify the same communication session indicator. The first participant leads the session by requesting URL and hypertext links to the server computer 30. The server computer 30 retrieves Internet website information corresponding to the URL and hypertext link requests, and directs the retrieved information to the remote communication session participants so as to provide concurrent viewing of the information to the remote participants. The participants can then discuss the information by voicing their opinions on the computer models or other computer information being concurrently displayed on their screens via a chat room format .
[00017] In another example of the method, a first participant logs on to the system and specifies a user defined communication session indicator by providing a communication session identification code that is only known to a select group. Other members of the select group, may then log on and gain entrance to the communication session by providing the proper communication session identification code to the server computer 30. The first participant leads the session by requesting URL and hypertext links to the server computer 30. The server computer 30 retrieves Internet website information corresponding to the URL and hypertext link requests, and directs the retrieved information to the remote communication session participants so as to provide concurrent viewing of the information to the remote participants. The participants can then discuss the information being concurrently displayed on their screens via either a preselected chat room format or conference call via VoIP.
[00018] Although the various aspects of the present invention have been described with respect to a preferred embodiment, it will be understood that the invention is entitled to full protection within the full scope of the appended claims.
