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.

摘要： A system and method for specifying requirements for the consumption of an MB MS user service. This system and method is forward-compatible and allows for legacy terminals to detect if a new feature, introduced in later releases, is required for the consumption of the service. If a required feature is not supported, then the terminal will not attempt to join the session. The service announcement or service discovery carries information about the requirements for the MBMS user service. Any requirement that is not understood by the terminal indicates to the terminal that it cannot correctly receive and decode the service.

摘要： A system and method for signaling and indicating track relationship infor mation in media files. The present invention provides a mechanism for signal ing the information of layered track groups and the information of MDC track groups, as well as a mechanism for signaling track relationship information in an efficient way. In local playback or unicast streaming applications, t o select an independently decodable track for a certain media type, the info rmation of alternate track groups is first found via the track relation box, and one track is selected from an alternate track group for the media type. If stream switching is desired, the switching track group information is fo und via the track relation box. In multicast applications with scalable or M DC streams, the tracks in a layered or MDC group are found via the track rel ation box and selected among all the layered or MDC groups.

摘要： Systems and methods applicable, for instance, in data delivery. For example a service operator server and/or other computer might act to determine which of point-to-point repair mode and point-to-multipoint repair mode should be employed in the case where one or more receivers do not correctly receive dispatched data. As another example, the service operator server and/or other computer might calculate one or more estimates, request one or more values from one or more repair servers, and/or provide to one or more repair servers one or more directives regarding repair mode to be employed.
