摘要： In a multimedia streaming network where a client has a receiver buffer to store packets received from a server to compensate for difference between data transmission amount by server and data usage amount by client, server should be able to adapt the data transmission rate based on the status of the receiver buffer. For rate adaptation purposes, server reconstructs a list of packets in the receiver buffer based on information provided by client. Information signaled to server is indicative of the next unit to be decoded and the sequence number of the packet to which the next unit to be decoded belongs, or the next packet to be decoded in client, the DON number of the next NAL unit or the sequence number of the packet carrying the next NAL unit to be decoded and the DON indicative of the decoding order of that next NAL unit.

摘要： A system and method for implementing improved decoded picture buffer (DPB) management for scalable video coding and multiview video coding. To address the issue of mismatches in reference picture markings, all prior unnecessary reference pictures can be marked as unused after the decoding of an open decoding refresh (ODR), open layer refresh (OLR), or open view refresh (OVR) picture or, when scalable video coding (SVC) is at issue, an indication can be made in the stream that previous and current reference picture markings are identical. To address the occurrence of potential overflows in the decoded picture buffer, ODR, OLR, or OVR pictures may not be encoded if a switch can cause an overflow m the decoded picture buffer; all prior pictures may be removed from the decoded picture buffer; or prior pictures may removed from the DPB based on certain control indications. Solutions are also provided to address the issue of mismatches in bi-dependent leading pictures.
摘要翻译：一种用于实现用于可缩放视频编码和多视图视频编码的改进的解码图像缓冲器（DPB）管理的系统和方法。为了解决参考图像标记中的不匹配问题，在解码开放解码刷新（ODR），开放层刷新（OLR）或打开视图刷新（OVR）图像之后，可以将所有先前不必要的参考图片标记为未使用，当可伸缩视频编码（SVC）出现问题时，可以在流中进行指示，即先前和当前的参考图片标记是相同的。为了解决解码图像缓冲器中潜在的溢出的发生，如果开关可能导致解码的图像缓冲器溢出，则ODR，OLR或OVR图像可能不被编码; 可以从解码图像缓冲器中去除所有先前的图像; 或者可以基于某些控制指示从DPB去除现有图像。还提供了解决方案来解决双重依赖的主要图片中的不匹配问题。

摘要： A system and method for implementing low complexity multi-view video coding. According to various embodiments, single-loop decoding is applied to multi-view video coding. For N coded views, where only M of the N views are to be displayed, only those M views are required to be fully decoded and stored to a decoded picture buffer (DPB) when needed. Pictures of other views are only partially decoded or simply parsed and do not have to be stored into the DPB. Various embodiments also provide for an encoder that encodes multi-view video bitstreams in accordance with the single-loop decoding concept, as well as a decoder that utilizes single-loop decoding to decode and output on a subset of the encoded views from a multi-view bitstream.

摘要： A device, an encoding method, and a decoding method enable a separate marking of base representations and enhanced representations of key access units to save memory or to allow a better scalable video coding optimization. The encoding method of a sequence of original pictures to a sequence of access units includes, after encoding of one of the access units, storing a first decoded picture of the first encoded picture and a second decoded picture of the second encoded picture for inter prediction for encoding of others of the access units; and identifying the first decoded picture and the second decoded picture to be no longer used for inter prediction. The decoding method includes decoding the first access unit, where a first decoded picture is decoded from the first picture and a second decoded picture is decoded from the second picture; marking the first and second decoded pictures as used for inter prediction; decoding the second access unit; and marking one of the first and second decoded pictures as no longer used for inter prediction.
