摘要： In an embodiment, an application server determines a priority associated with a given multicast message for transmission to at least one access terminal, configures the given multicast message to indicate the priority of the given multicast message and forwards the configured multicast message to an access network for transmission to the at least one access terminal a number of times based at least in part on the indicated priority. Alternatively, the application server can indicate, in the configured multicast message, the number of times to transmit the given multicast message. The priority, or number of times to transmit the given multicast message, can be conveyed to the access network by a flag inserted into the configured multicast message by the application server. The access network determines the number of times to transmit the given multicast message to the at least one access terminal based on the flag.

摘要： マルチビットレートストリームを使用するビデオ会議のサブスクリプションを提供することができる。 ビデオ会議のサーバは、ビデオ会議の各クライアントからビデオストリームを受信することができ、各クライアントからサブスクリプション要求を受信することができる。 サブスクリプション要求は、特定の他のクライアントからのビデオストリームを、所与の解像度および／またはフレームレートで見るという要求を含むことができる。 ビデオ会議サーバは、サブスクライブしているクライアントに所望のビデオストリームを送信するために、受信したビデオストリームをサブスクリプション要求と突き合わせることができる。 サーバはまた、参加者からのビデオストリームの異なるバージョン（例えば、異なる解像度）を要求することができ、かつ／または、サブスクリプション要求によりよく応じるために、ビデオストリームを変更することもできる。

摘要： The present invention provides an IP broadcasting system that can receive IP broadcasting videos over an IP multicast network. In the IP broadcasting system, a multicast group management apparatus for IP broadcasting that holds multicast group identifiers is connected via an IP multicast network over which IP broadcasting services are provided. When a user issues a request to switch an IP broadcasting channel from an IP broadcasting terminal, a query message including the requested IP broadcasting channel identifier is transmitted to a management apparatus. The IP broadcasting terminal receives a response message indicating the correspondence between the IP broadcasting channel identifier and a multicast group identifier, and transmits a video reception request message to a multicast group by using the received multicast group identifier.

摘要： A point-to-multipoint communication system that is well operative for transmitting megabytes of information in the form of a signal burst. Each slave unit temporarily stores a signal and measures the amount of the signal information before transmitting the signal. A master unit requests that slave units report the measured amounts of information, and they give reports to the master unit. On the basis of the reports from the slave units, the master unit determines an allowable amount of information for each slave unit and permits the slave units to transmit the stored signals according to the request from the master unit. The interval between the reports from the slave units to the master unit can be varied.

摘要： PROBLEM TO BE SOLVED: To provide a communication system capable of excellently communicating information signals. SOLUTION: A point-to-multipoint communication system includes: a determination means for determining the allowable amount of signals permitted to be transmitted to a slave unit for each kind of information relating to the signals on the basis of the amount of accumulated signals declared from the slave unit; a transmission wait time determination means for determining a transmission wait time so as to give a transmission permission to transmit, from among the signals, signals of a type whose allowable delay time is short, within a fixed time; and a transmission instruction means for periodically instructing the slave unit to transmit the signals based on the allowable amount determined by the determination means on the basis of the transmission wait time determined by the transmission wait time determination means for the signals of the type whose allowable delay time is short, and instructing the slave unit to transmit the signals based on the allowable amount determined by the determination means with the remaining transmission capacity after instructing the transmission of information signals of the type whose allowable delay time is short, for signals of a type whose allowable delay time is longer relatively to the signals of the type whose allowable delay time is short.
