    摘要： Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular method includes accessing a video picture that includes multiple pictures combined into a single picture, accessing information indicating how the multiple pictures in the accessed video picture are combined, decoding the video picture to provide a decoded representation of at least one of the multiple pictures, and providing the accessed information and the decoded video picture as output. Some other implementations format or process the information that indicates how multiple pictures included in a single video picture are combined into the single video picture, and format or process an encoded representation of the combined multiple pictures.

    摘要： Various implementations are described. Several implementations relate to video and depth coding. One method includes selecting a component of video information for a picture. A motion vector is determined for the selected video information or for depth information for the picture. The selected video information is coded based on the determined motion vector. The depth information is coded based on the determined motion vector. An indicator is generated that the selected video information and the depth information are coded based on the determined motion vector. One or more data structures are generated that collectively include the coded video information, the coded depth information, and the generated indicator.

    摘要： An encoder, a decoder, corresponding encoding and decoding methods, video signal structure, and storage media are provided for scalable video encoding and decoding. A scalable video encoder includes an encoder (100) for encoding a picture to form a base layer bitstream and an enhancement layer bitstream. The base layer bitstream and the enhancement layer bitstream are formed by partitioning the picture into a plurality of image blocks, grouping the plurality of image blocks into one or more slice groups in the base layer bitstream and into two or more slice groups in the enhancement layer bitstream, encoding all of the one or more slice groups in the base layer bitstream and less than all of the two or more slice groups in the enhancement layer such that at least one slice group from among the two or more slice groups is intentionally un-encoded in the enhancement layer bitstream, encoding a syntax element in a header to indicate the at least one intentionally un-encoded slice group in the enhancement layer.

    摘要： There are provided methods and apparatus at an encoder and decoder for supporting single loop decoding of multi-view coded video. An apparatus includes an encoder for encoding multi-view video content to enable single loop decoding of the multi-view video content when the multi-view video content is encoded using inter-view prediction. Similarly, a method is also described for encoding multi-view video content to support single loop decoding of the multi-view video content when the multi-view video content is encoded using inter-view prediction. Corresponding decoder apparatus and method are also described.

    摘要： There are provided methods and apparatus supporting a multi-pass video structure for slice data. An apparatus includes an encoder for encoding at least one syntax data element related to at least two partitions of at least a portion of a picture. The at least one syntax element is encoded within a multi-pass syntax structure. The at least one syntax element belongs to a given class of data. The encoder encodes the at least one syntax data element with respect to all partitions of at least the portion of the picture prior to encoding a next class of data, wherein later coded data classes, including the next class, have at least one of an explicit coding and an implicit coding of at least one of a casual dependency and a non-casual dependency with respect to earlier coded data classes coded earlier than the next class.
