Abstract: In a service providing system, a live-distribution service for live-distributing contents supplied according to a reservation, and a chat service for providing the use of a chat space corresponding to the reservation for the live distribution are provided. When a personal computer and another personal computer use the live-distribution service and the chat service, they need to be authenticated by a streaming server and a communication server. For authentication, both the streaming server and the communication server use a shared password registered in a reservation data base when the live distribution is reserved.

Abstract: In a service providing system, a live-distribution service for live-distributing contents supplied according to a reservation, and a chat service for providing the use of a chat space corresponding to the reservation for live distribution are provided. After the live distribution finishes, a communication server sends the whole or a part of the contents of chatting performed in the chat space corresponding to the reservation for the live distribution, to a personal computer. With this, even if the user of the personal computer, who supplies the contents, could not participate in a chat with a user of another personal computer while capturing the contents, for example, the user of the personal computer can check the contents of the chat later.

Abstract: A content distribution method where a user PC reserves a distribution channel at the live casting server in order to distribute content to the client PCs and requests the live casting server to post program presentation information on the content to be distributed on the distribution channel on the program presentation display screen of the top page screen, and the live casting server executes billing processing in response to the request, sends the top page screen having the program presentation display screen including the program presentation information, to the client PCs, which thereby allows the client users to see the program presentation information on the program presentation display screen of the top page screen first and increases the chances of selecting the program, resulting in distributing the content to much more client users.

Abstract: A content distribution system, content distribution control apparatus, content distribution control method, content distribution control program and content distribution control program storage medium realizes the distribution of content to much more clients.

Abstract: A server for providing to a user terminal an additional service on a web page during setting a predetermined service including a determining unit configured to determine whether a request for provision of the additional service is received from the user terminal; a receiving unit configured to receive presentation information for introducing the predetermined service from the user terminal when the determining unit determines the request for provision of the additional service is received; a creating unit configured to create the web page including the presentation information; a posting unit configured to post the web page; and a fee charging unit configured to charge a fee for the additional service.

Abstract: In content distribution, even if a reservation for a distribution channel and a distribution time slot is not performed before a predetermined time is reached, in response to a real-time distribution reservation request from a user PC, a predetermined time period including a current time at which the request is received is reserved in a channel which is unoccupied at the current time. A reservation setting information file concerning the reservation is also transmitted to the user PC, and reservation data is sent to a server-use reservation management center. Thus, the content received from the user PC is immediately distributed to clients via a streaming server according to the reservation setting information file.

Abstract: A user PC sends an extension request for extending a time slot to a server-use reservation management center while distributing content to client PCs via a streaming server in a distribution channel and in the time slot. The server-use reservation management center sends a new reservation setting information file in which an extended time is set in response to the extension request to the user PC, and also sends extension information to the streaming server. Accordingly, the user PC is allowed to continue to send the content to the streaming server based on the new reservation setting information file, and the streaming server is allowed to continue to distribute the content. Thus, even when it is desired that the time slot be extended while the distribution is being performed, the content can be continuously distributed without suspending the distribution or making a new reservation.

Abstract: In content distribution, even if a reservation for a distribution channel and a distribution time slot is not performed before a predetermined time is reached, in response to a real-time distribution reservation request from a user PC, a predetermined time period including a current time at which the request is received is reserved in a channel which is unoccupied at the current time. A reservation setting information file concerning the reservation is also transmitted to the user PC, and reservation data is sent to a server-use reservation management center. Thus, the content received from the user PC is immediately distributed to clients via a streaming server according to the reservation setting information file.
