## Background
CROSS-REFERENCE TO RELATED APPLICATION
This is a continuation application of pending U.S. patent application Ser. No. 09/820,530, filed Mar. 29, 2001, which claims priority to Japanese Application No. 2000-351911, filed Nov. 17, 2000. The disclosures of these documents, including the specifications, drawings and claims, are incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method and apparatus for joining an electronic conference, and particularly to a method and apparatus for joining an electronic conference by using a simple procedure from a video game machine.
2. Description of the Related Art
Video game machines with an Internet connection function can receive various services via servers of ISPs (Internet Service Providers). With these new services, for example, game software is distributed to video game machines and users can play battle games via a network. On the other hand, other new services can be provided by combining services relating to games with services such as electronic mail and conferences (hereafter referred to as “chats”) which are conventionally provided on the Internet.
In a battle game, users playing the game via a network may be opponents or allies. If users who have become acquainted through a game have means for communication, they can exchange information on games to increase enjoyment such of games. Further, if not only one-on-one battle games but also games that can be joined by many players are available, information exchanged based on chats are effective.
A problem with conventional video game machines, however, is that they have the Internet connecting function but no application program for electronic mail or chats, thus requiring a separate general-purpose computer in order to send electronic mail or have chats.
Further, the conventional video game machines require various procedures with an ISP, which are cumbersome both to a chat chairman and to guests. Moreover, if new guests are invited while a chat opening process is in progress, complicated procedures are required, thus making it difficult to increase chat guests.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Embodiments of the present invention will be described below in detail with reference to the drawings.
FIG. 1 shows an example of a system configuration for providing electronic conference opening according to the present invention. The Internet 101 has a server of an ISP, video game machine 103a and 103b, and general-purpose components 104a and 104b connected thereto.
The ISP servers 102 comprises multiple servers including an authentication server 111 for managing accounts to authenticate users, a content server 112 for providing services for allowing users to listen to and view content such as sounds or videos, a message server 113 for providing environments for chats or messengers, a mail server 114 for providing electronic mail services, a profile server 115 for managing users' profiles, and game servers 116a and 116b for providing game environments, all of these servers are connected to the ISP server via a LAN 117.
With this configuration, a user accesses the authentication server 111 from the video game machine 103a or 103b or the general-purpose computer 104a or 104b via the Internet 101, to have the user authenticated. The servers 102 transmit a menu screen to the authenticated user. The user selects one of services displayed on the menu screen to connect the video game machine 103a or 103b or the general-purpose computer 104a or 104b to one of the groups of servers depending on the service, so that the user can receive the service.
FIG. 2 shows an example of electronic conference opening of the present invention. A user who desires to open a chat creates a message 201 for opening a chat, on the video game machine 103a. When this message is sent, a chat opening request signal 202 is transmitted to the message server 113. The latter transmits a setup signal 203 for opening the desired chat room to a database in the group of servers and returns a chat opening response signal 204 to the user. The opening of a chat refers to an operation performed by the message server 113 to set a specified area in the database and grant accesses only to particular users, that is, chat guests.
Upon receiving the chat opening response signal 204, the user can enter (join) the chat room by transmitting an enter room signal 205 to the database. The entry to a chat room refers to an operation of having the user's access checked by the message server 113 to access a predetermined area of the database.
Further, a message 206 for invitation to the chat which is transmitted to the chat guests is displayed based on the created message 201, and an invitation signal 207 is transmitted to all the guests. The video game machine 103b of an expected guest receiving the invitation signal 207 displays a screen 210 prompting the guest to enter the chat room, and the expected guest can join the chat by transmitting a enter room signal 208 to the database. At this time, an invitation answer signal 209 indicating that the guest accepts the chairman's invitation is transmitted from the expected guest to the chairman. The invitation to a chat refers to an operation of granting a guest access to an opened chat room and prompting the guest to join the chat.
After a chat has been opened, the invitation signal 207 can also be transmitted to new chat guests. The video game machine 103c, not shown in FIG. 1, of an expected guest receiving the invitation signal 207 displays the screen 210 prompting the guest to enter the chat room, and the expected guest can join the chat by transmitting the enter room signal 208 to the database. At this time, the invitation answer signal 209 indicating that the guest accepts the chairman's invitation is transmitted from the expected guest to the chairman.
FIG. 3 shows an example of a message for opening a chat in the electronic conference opening of the present invention. This corresponds to the chat opening message 201 shown in FIG. 2 and is created and transmitted to the message server 113 by the chairman. The contents of the chat opening message 201 request the message server 113 to open the chat room and to transmit the invitation message to the expected guests.
The chat opening message 201 has a category 301 indicative of a type of message, and a message title 302 and a text box 303 that are required to transmit the invitation message to the expected guests. The message 201 also has input columns for a chat name 304 and a chat password 305 which are required to request the message server 113 to open the chat room.
FIG. 4 shows an example of a chat opening data signal format in the electronic conference opening of the present invention. This corresponds to the invitation message 206 shown in FIG. 2 and is created by the video game machine 103a based on the chat opening message 201 created by the chairman. The setup information input to create the chat opening message 201 has been stored and is used to create the invitation message 206. The invitation message 206 differs from the chat opening message 201 shown in FIG. 3 in that the chat name 304 input through the chat opening message 201 is displayed as a room name 401 in the invitation message 206. The chat password 305 will be described later.
The invitation message 206 can be invoked while the chat opening process is in progress. The user can invoke and edit the invitation message 206 by performing an operation required to invoke the message or selecting guests from an address book while the chat opening process is in progress. Then, after the chat has been opened, the invitation signal 207 can be transmitted to other guests.
FIG. 5 shows an example of an invitation data signal format in the electronic conference opening of the present invention. This data signal format corresponds to the invitation signal 207 shown in FIG. 2 and is created by the video game machine 103a based on the invitation message 206. The video game machine 103a sets a user name 501 and a user ID 502 of the chairman which have already been registered. An “invitation” command 511 is generated by obtaining a chat name 512 and a chat password 513 from the contents of the chat opening message 201 and obtaining a chat ID 514 from the contents of the chat opening response signal 204.
The chat password 513 is set by obtaining it from the chat password 305 in the chat opening message 201 but is not displayed in the invitation message 206 shown in FIG. 4. The chat ID 514 is also not displayed. Upon receiving the invitation message 207, the video game machines 103b and 103c display the screen 210 prompting the guests to enter the chat room and create the Enter Room signal 208. The screen 210 prompting the guests to enter the chat room also does not display the chat password 513 or the chat ID 514. That is, the chat password 513 and the chat ID 514 are recognized by the video game machines 103a to 103c during the exchange of the signals but are not communicated to the guests through the screen. When cumbersome procedures required to set a chat are thus omitted, users can open and join a chat by means of a simple procedure from a video game machine.
FIG. 6 shows an example of a data signal format for entering a chat room in the electronic conference opening of the present invention. This data signal format corresponds to the enter room signals 205 and 208 shown in FIG. 2. Here, the enter room signal 208 will be explained. When the guest selects “Enter Room” in the screen 210 prompting the guests to enter the chat room, the video game machines 103b and 103c create and transmit the enter room signal 208 to the database of the group of message servers 113. The video game machine 103b sets a user name 601, a user ID 602, and a user password 603 of the chairman which have already been registered. An “Enter Room” command 611 is generated by obtaining the chat name 512, the chat password 513, and the chat ID 514 from the contents of the invitation signal 207.
According to this embodiment, even while the chat opening process is in progress , the video game machine 103a can invoke the invitation message 206 so that the invitation signal 207 can be transmitted based on this message, thereby eliminating the need for cumbersome procedures for inviting guests. Further, the guests can join chats without any cumbersome procedure because the video game machines 103b and 103c generate the enter room signal 208 from the contents of the invitation signal and transmit this signal.
FIG. 7 shows an example of a video game machine having the electronic conference opening ability of the present invention mounted therein. The video game machine 103 has a CPU 711 for controlling the entire machine, a ROM 712 storing game programs and a program for the electronic conference opening of the present invention, a RAM 713 as a temporary storage area, and an Application Specific IC (ASIC) 714 for processing images, which are connected together via a bus 715.
A CD-ROM drive 716 for loading the game programs and the program for the electronic conference opening of the present invention, from the CD-ROM storing these programs, a serial interface 717 connected to the game controller 701, a video interface 718 connected to a TV monitor 702, and a communications interface 719 for connection to the Internet 101 are also connected to the bus 715.
Of course, the present invention is achieved by causing the video game machine or general-purpose computer to read and execute program code of software from the storage medium storing these program codes, the software implementing the electronic conference opening of the present invention. The storage medium for supplying the program code may include, for example, a floppy disk, a hard disk, a photo-electromagnetic disk, an optical disk, a CD-ROM, a CD-R, a magnetic tape, a non-volatile memory card, and a ROM.
The electronic conference opening of the present invention is applicable not only to standalone general-purpose computers but also to a client server system including a group of computers
