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 improving both coding efficiency and decoding accuracy in scalable video coding involving discardable lower layer adaptations, where applications can omit transmission of unused data for inter-layer prediction for all layers below an operation point of receivers. Indicator flags are utilized to avoid transmitting syntax elements that must be set to fixed values. In addition, padding algorithms or additional encoding constraints are applied to the encoding process.

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 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： In a start code based bistream structure for use in video coding, a picture header is used simultaneously with the parameter set in the start code. The picture header is present before the slice header in the same picture. As such, it is possible to allow the presence of at least one sequence parameter set or picture parameter set before the slice header. In a NAL unit parameter set bitstream structure, the picture head NAL unit is present before the slice NAL unit. In either structure, the picture header information must remain unchanged during the decoding of the entire picture, but should change more frequently between pictures as compared to the information in the picture parameter set.

摘要： The exemplary embodiments of this invention provide in one aspect thereof an ability to signal multiple decoding times for each sample in a file format level in order to allow, for example, different decoding times for each sample (or sample subset) between decoding an entire stream and decoding a subset of the stream. An alternate decoding time box is specified to allow for the signaling of multiple decoding times for each sample. Such a box can contain a compact version of a table that allows indexing from an alternate decoding time to a sample number, where an alternate decoding time is a decoding time to be used with a sample when only a subset of an elementary stream stored in a track is to be decoded. Furthermore, each entry in the table provides the number of consecutive samples with the same time delta, and the delta between those consecutive samples. By adding the deltas a complete time-to-sample map can be constructed.
