摘要： A system and method for providing faster tuning into a chosen program in a time- sliced multicast and/or broadcast transmission environment. Multimedia data of the same source material but of different transmission and presentation characteristics are coded and compressed. According to various embodiments, simulcast streams of a program are time-sliced, placed maximally apart from each other in terms of transmission time, and sent over the channel.

摘要： A system and method for signaling and indicating track relationship information in media files. The present invention provides a mechanism for signaling 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, to select an independently decodable track for a certain media type, the information 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 found via the track relation box. In multicast applications with scalable or MDC streams, the tracks in a layered or MDC group are found via the track relation box and selected among all the layered or MDC groups.
摘要翻译：用于在媒体文件中发信号通知和跟踪关系信息的系统和方法。本发明提供了一种用于对分层轨道组的信息和MDC轨道组的信息进行信令的机制，以及用于以有效的方式发送跟踪关系信息的机制。在本地播放或单播流应用中，为了选择特定媒体类型的独立解码的音轨，首先通过音轨关系框找到备用音轨组的信息，并从媒体类型的备用音轨组中选择一个曲目。如果需要流切换，则通过轨道关系框找到切换轨道组信息。在具有可扩展或MDC流的多播应用中，分层或MDC组中的轨道通过轨道关系框找到并在所有分层或MDC组中选择。

摘要： Systems and methods for storing notification messages in an ISO base media file are provided, where different transport cases when notification messages are to be stored are addressed. The systems and methods enable the linking of notification message parts delivered over RTP with other parts of a notification message carried over file delivery over unidirectional transport (FLUTE) or some other protocol. Various implementations of the systems and methods can be generic and allow objects delivered out-of-band to be referenced from media and hint tracks. Additionally the lifecycle of notification objects can be reproduced in the file without timers required in the parsing of the file.
摘要翻译：提供了用于将通知消息存储在ISO基本媒体文件中的系统和方法，其中解决了存储通知消息时的不同传输情况。该系统和方法使得能够将通过RTP传递的通知消息部分与通过单向传输（FLUTE）或某种其他协议的文件传递携带的通知消息的其他部分链接起来。系统和方法的各种实现可以是通用的并且允许从带外传送的对象从媒体和提示轨道被引用。另外，通知对象的生命周期可以在文件中再现，而不需要解析文件中的定时器。

摘要： Systems and methods of signaling changes and updates associated with the default notification channels in a non-time sliced way are provided. A default notification channel event is signaled to a terminal. The signaling includes a reference to the relevant default notification channel, a timestamp, and/or a version number/counter. A comparison is made between a stored timestamp and/or version number/counter with the timestamp and/or version number/counter indicated in the signaling. A more recent timestamp and/or version number/counter prompts the terminal to tune in to the default notification channel to process the default notification channel event. The signaling can be performed using Program Specific Information/Service Information (PSI/SI), which is non-time-sliced and is received by all terminals. Additionally, the PSI/SI signaling is effectuated by creating descriptors in existing notification/network information tables and/or by creating a dedicated notification signaling table.

摘要： Various embodiments provide for the splitting of a notification message to a user, where the notification message enables at least one of interactivity and delivery of information associated with a media broadcast service. A first component of the notification message carries media content and is transmitted utilizing a file delivery protocol, such as FLUTE, HTTP, and OMA-PUSH. A second component of the notification message carries any synchronization information associated with the interactivity and the delivery of the information associated with the media broadcast service. The second component of the notification message can be transported in an RTP payload via RTP to allow for accurate synchronization of the notification message with a media stream of the media broadcast service containing the media content.

摘要： A system and method for specifying requirements for the consumption of an MBMS 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： An accurate indication of a re-synchronization point/time in streamed media content is provided to allow playout of the streamed media content from or at a desired point/time when a client or receiver switches from multimedia broadcast multicast service (MBMS) to packet switch stream (PSS) service. Various parameters, e.g., synchronization source (SSRC) and real-time protocol (RTP) timestamp, of a last received media RTP packet is signaled to a receiver. Alternatively, the SSRC and sequence number of the last received media RTP packet is signaled to the receiver, or the SSRC, the RTP timestamp, and the sequence number of the last received media RTP packet is signaled to the receiver. Also, a UTC clock time can be calculated based upon the last received real-time control protocol (RTCP) sender report (SR) and the timestamp of the last received media RTP packet in order to effectuate proper synchronization between MBMS and PSS servers.
摘要翻译：提供流传输媒体内容中的重新同步点/时间的准确指示以允许当客户端或接收器从多媒体广播多播服务（MBMS）切换到分组交换时在期望的点/时间播出流媒体内容流（PSS）服务。将最后接收的媒体RTP分组的各种参数（例如，同步源（SSRC）和实时协议（RTP）时间戳）信号发送给接收器。或者，将最后接收到的媒体RTP分组的SSRC和序列号发送给接收器，或者将SSRC，RTP时间戳以及最后接收到的媒体RTP分组的序列号发送给接收器。而且，可以基于最后接收到的实时控制协议（RTCP）发送者报告（SR）和最后接收的媒体RTP分组的时间戳来计算UTC时钟时间，以便实现MBMS和PSS服务器之间的适当同步。

摘要： A system and method for ensuring transition at the application layer when distribution of media is changed from broadcast/multicast bearers to unicast bearers and vice versa. A mapping is defined between the timeline of a Packet- Switched. Streaming Service (PSS) session and the Multimedia Broadcast Multicast Service (MBMS) session timeline. This mapping is used to enable the correct positioning of the s.tream in a PSS session by a PSS server after a handover has occurred. Broadcast multicast service center. (BM-SC) signals can support various options for media playback after a MBMS-PSS handover in a PSS session description protocol (SDP) file or in the MBMS user service description (USD). In response, the client can signal its choice in the RTSP request that is sent when switching to the PSS session.
