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.

摘要： A system and method of modifying error resiliency features by conveying temporal level 0 picture indices, such as tl0_pic_idx, within an SEI message instead of optionally including them in the NAL unit header is provided. In addition, a mechanism is provided for enabling repetition of any SEI messages in Real-Time Transport Protocol (RTP) packets. Enabling such repetition of any SEI messages facilitates detection of lost temporal level 0 pictures on the basis of any received packet.

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 video coding and decoding method, wherein a picture is first divided into sub-pictures corresponding to one or more subjectively important picture regions and to a background region sub-picture, which remains after the other sub-pictures are removed from the picture. The sub-pictures are formed to conform to predetermined allowable groups of video coding macroblocks (MBs). The allowable groups of MBs can be, for example, of rectangular shape. The picture is then divided into slices so that each sub-picture is encoded independent of other sub-pictures except for the background region sub-picture, which may be coded using another sub-pictures. The slices of the background sub-picture are formed in a scan-order with skipping over MBs that belong to another sub-picture. The background sub-picture is only decoded if all the positions and sizes of all other sub-pictures can be reconstructed on decoding the picture.
摘要翻译：一种视频编码和解码方法，其中首先将图像划分为与一个或多个主观重要的图像区域对应的子图像和在从图像中移除其它子图像之后保持的背景区域子图像。子图像形成为符合预定的允许的视频编码宏块（MB）组。 MB的允许组可以是例如矩形。然后将图像分成片，使得每个子图像独立于除了背景区域子图像之外的其他子图像，其可以使用另一个子图像进行编码。背景子图像的切片以扫描顺序形成，跳过属于另一子图像的MB。只有在对图像进行解码时可以重构所有其他子图像的所有位置和大小时，才解码背景子图像。
