摘要： A method and system for compressed domain video mixing for spatially combining incoming video streams into an outgoing video stream. Using H.264 as an example, each incoming stream is divided into a plurality of slices, each having a plurality of header fields including a first_mb_in_slice header field. Based on the picture format in the outgoing stream, first_mb_in_slice for each incoming stream is modified such that the modified first_mb_in_slice header field is indicative of location in the spatial representation of the outgoing stream at which the slice of the incoming stream is placed. H.264's slice group mechanism is used to map the spatial positions of the second and following macroblocks of the slices to the appropriate locations. If the incoming streams are previously mixed by upstream mixers, a decomposer can be used to separate these mixed streams into component streams before combining them with other incoming streams.
摘要翻译：一种用于压缩域视频混合的方法和系统，用于将输入视频流空间合并成输出视频流。使用H.264作为示例，每个传入流被划分为多个片，每个片具有包括first_mb_in_slice标题字段的多个标题字段。基于输出流中的图像格式，修改每个输入流的first_mb_in_slice，使得修改的first_mb_in_slice报头字段指示输入流的切片在其上放置的输出流的空间表示中的位置。 H.264的片组机制用于将切片的第二个和后续宏块的空间位置映射到适当的位置。如果输入流预先由上游混频器混合，则可以使用分解器将这些混合流分组成分量流，然后将它们与其他输入流组合。

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： The invention relates to a method for assembling FEC frames for a sequence of groups of coded media packets. In order to reduce a buffer delay at a decoding end (15), it is proposed that the FEC frame is aligned with the groups of media packets. To this end, a number of next subsequent groups is determined, which fit completely into a FEC frame. All coded media packets associated to this determined group or groups, if any, are selected for the FEC frame (step 202,402). Then, the selected coded media packets are encoded to obtain at least one FEC packet for the FEC frame (step 206,406). For fixed FEC frame structures, moreover the introduction of padding packets as additional media packets, if required, is proposed.

摘要： A system and method for enabling the removal of decoded pictures from a decoded picture buffer as soon as the decoded pictures are no longer needed for prediction reference and future output. An indication is introduced into the bifstreara as to whether a picture may be used for mter-layer prediction reference, as well as a decoded picture buffer management method which uses the indication. The present invention includes a process for marking a picture as being used for inter-layer reference or unused for inter-layer reference, a storage process of decoded pictures into the decoded picture buffer, a marking process of reference pictures, and output and removal processes of decoded pictures from the decoded picture buffer.
