摘要： Systems and methods for enforcing playback of a specific portion of the content in an open non-certified media player/renderer are provided. In accordance with such systems and methods, a key is extracted from a content portion for which playback is to be forced. The extracted key allows a client the ability to gain access to additional/remaining content. Moreover, the existence of forced content, the mechanism(s) utilized for forcing playback, as well as a particular position in the timeline associated with the forced playback are signaled to the client on/through which the open non-certified media player/renderer is implemented.

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修复媒体分组，比其预期的解码时间晚，从而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。可以利用用于子序列解码的“循环”保留“，通过在子序列开始时冻结解码的帧，并将作为先前FEC块的一部分的主序列的编码图像解码为主预测的完整性可以再次建立链路，或者也可以使用来自增强层解码的循环。

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.
