摘要： A system and method for signaling and indicating track relationship information in media files provides a mechanism for signaling the information of layered track groups and the information of multiple description coding (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： A real-time program transmission system and method may receive a signal from a content source, and generate two different data streams. One stream may be of a higher quality than the other. The two streams may then be inserted into time slice frames, such that a single frame carries two portions of data: one corresponding to a first time segment in the program, and a second corresponding to a different time segment in the program. A receiving mobile terminal may buffer the received data, and may use the lower quality data as a backup in the event of a transmission error in the higher quality data.
摘要翻译：实时程序传输系统和方法可以从内容源接收信号，并生成两个不同的数据流。一条流可能具有比其他流更高的质量。然后可以将两个流插入到时间片帧中，使得单个帧携带两个数据部分：一个对应于节目中的第一时间段，另一个对应于节目中的不同时间段。接收移动终端可以缓冲接收的数据，并且可以在较高质量数据中发生传输错误的情况下使用较低质量数据作为备份。

摘要： Accelerated video decoding makes use of FEC-repaired media packets that become available through FEC decoding later than their intended decoding time, so to re-establish the integrity of the prediction chain between predicted pictures. The decoder state may be stored at the time of reception of an erroneous packet or at the time of identification of a lost packet, and decoding continued. After FEC repair, the last known state of the decoder is restored after the lost/damaged packet(s) is (are) resurrected through FEC, and accelerated decoding accordingly is used. Cycles “reserved” for decoding of a sub-sequence may be utilized. By freezing the decoded frame at the begin of a sub-sequence and decoding coded pictures of the main sequence that are part of the previous FEC block the integrity of the main prediction chain may be established again. Alternatively, cycles from enhancement layer decoding may be used.
摘要翻译：加速视频解码利用FEC解码后的FEC修复媒体包比其预期的解码时间晚，因此重新建立预测图像之间的预测链的完整性。解码器状态可以在接收到错误的分组时或在识别丢失的分组时被存储，并且继续解码。在FEC修复之后，在通过FEC复原丢失/损坏的分组之后恢复解码器的最后一个已知状态，并且相应地使用加速解码。可以使用用于子序列解码的“保留”周期。通过在子序列开始时冻结解码的帧并对作为先前FEC块的一部分的主序列的编码图像进行解码，可以再次建立主预测链的完整性。或者，可以使用来自增强层解码的循环。

摘要： Provided are apparatuses and methods for reducing channel switching time in a network environment. The user of a mobile terminal may receive a data stream containing numerous television programs or services. Each of the programs or services may have a Packet Identification (PID) and/or IP address. The invention reduces channel switching time by predicting channel changing behavior. Various procedures are presented in which data is received and cached. The cached data may then be used to reduce the channel switching time during synchronizing and decoding of the new channel.
