摘要： A system and method for replacing existing media streams of a streaming session with alternative media streams, without tearing down the RTSP session and providing only a minimal delay. In various embodiments of the present invention, the client indicates to the server that it wishes to replace a media stream that it is currently consuming with another stream by sending a switch command to the streaming server, with the switch command indicating the old media stream and the new media stream. A feature is also provided for enabling the receiver to mute and unmute a single media stream. A client may query the server to find out whether fast channel switching is supported by the server.

摘要： An extension to a file delivery protocol which permits the signaling of cache control information to a receiving device. Various embodiments of the present invention permit a server or other sending device to signal instructions regarding cache control to a receiving device using the file delivery protocol. This signaling may include information such as whether the receiving device should cache a file, how long the file should be cached for, and/or a cache priority assignment for the file. Various embodiments of the present invention may be particularly useful in the transmission of rich media content, where some content may be sent over RTP while other information is transmitted via the file delivery protocol.

摘要： For the notification of a receiving device about a forthcoming transmission session, an identifier of one of various possible types of identifiers in a transmission session is mapped to a transmission session identifier field. This field is used for notifying the receiving device. Further, a repetition value is added to the transmission session identifier field, which indicates whether the forthcoming transmission session is new or not. Further, the receiving device may release context data stored for a particular transmission session identifier, if an acquisition of data in transmission sessions identified by the transmission session identifier can be terminated.
