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(1010, 1040). The selected video information is coded based on the determined motion vector (1015). The depth information is coded based on the determined motion vector (1035). An indicator is generated that the selected video information and the depth information are coded based on the determined motion vector (1030, 1050). One or more data structures are generated that collectively include the coded video information, the coded depth information, and the generated indicator (1065, 1070).

摘要： Various implementations are described. Several implementations relate to depth coding. According to a general aspect, prediction mode information is accessed for reconstructing a target block of data from a picture. The prediction mode information indicates that the target block of data was predicted using a target-block prediction mode that was determined based on a neighbor-block prediction mode of a neighbor block. The neighbor block is a spatial neighbor of the target block in the picture. The neighbor-block prediction mode of the neighbor block is determined. The target-block prediction mode of the target block is determined based on the neighbor-block prediction mode. The target block is reconstructed by predicting the target block using the determined target-block prediction mode.

摘要： Various implementations are described. Several implementations relate to determining, providing, or using a depth value representative of an entire coding partition. According to a general aspect, a first portion of an image is encoded using a first-portion motion vector that is associated with the first portion and is not associated with other portions of the image. The first portion has a first size. A first-portion depth value is determined that provides depth information for the entire first portion and not for other portions. A second portion of an image is encoded using a second-portion motion vector that is associated with the second portion and is not associated with other portions of the image. The second portion has a second size that is different from the first size. A second-portion depth value is determined that provides depth information for the entire second portion and not for other portions.

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.
