摘要： A video coder may utilize large macroblocks having more than 16x16 pixels. Syntax for the large macroblocks may define whether a bitstream includes large macroblocks, such as superblocks having 64x64 pixels or bigblocks having 32x32 pixels. The syntax may be included in a slice header or a sequence parameter set. The large macroblocks may also be encoded according to a large macroblock syntax. The bitstream may further include syntax data that indicates a level value based on whether the bitstream includes any of the large macroblocks, for example, as a smallest-sized luminance prediction block. A decoder may use the level value to determine whether the decoder is capable of decoding the bitstream.

摘要： This disclosure relates to techniques for reducing a cost of coding prediction information in video coding. Video blocks in a generalized P/B (GPB) frame are encoded using up to two motion vectors calculated from reference pictures in two separate reference picture lists that are identical. When one of the reference picture lists is preferred over the other reference picture list, the preferred reference picture list may be used for unidirectional prediction, by default. When a GPB frame is enabled such that the first and second reference picture lists are identical, either of the first and second reference picture lists may be used for unidirectional prediction. The techniques include coding one or more syntax elements indicating that a video block is coded using one of the unidirectional prediction mode with respect to a reference picture in a reference picture list and the bidirectional prediction mode using less than two bits.
