    摘要: Methods and apparatus for parsing friendly and error resilient merge flag coding in video coding are provided. In some methods, in contrast to merging candidate list size dependent coding of the merge flag in the prior art, a merge flag is always encoded in the encoded bit stream for each inter-predicted prediction unit (PU) that is not encoded using skip mode. In some methods, in contrast to the prior art that allowed the merging candidate list to be empty, one or more zero motion vector merging candidates formatted according to the prediction type of the slice containing a PU are added to the merging candidate list if needed to ensure that the list is not empty and/or to ensure that the list contains a maximum number of merging candidates.

    摘要: A method of intra-coding blocks of pixels in a digital video sequence is provided that includes selecting a block transform of a plurality of block transforms according to a spatial prediction mode used in generating a block of pixel residual values from a block of pixels, wherein the block transform is based on a single directional transform matrix predetermined for the spatial prediction mode and is a same size as the block of pixel values, applying the block transform to the block of pixel residual values to generate transform coefficients of the residual pixel values, and entropy coding the generated transform coefficients.

    摘要: This invention is a method of encoding intra frames when encoding a motion picture. A set of intra frame prediction modes includes a low-complexity subset. A probability table relates the prediction mode of adjacent sub-blocks to the prediction mode of the current sub-block. For each combination of adjacent sub-blocks, the probability table includes a list of prediction modes in order of expected occurrence. The probability table is adjusted so that each list for prediction modes within the low-complexity subset include initial prediction modes of the low-complexity subset. Individual sub-blocks of intra frames are predictively coded in a low-complexity encoding the using the low-complexity subset or in a high-complexity encoding using any prediction mode. This permits a low-complexity decoder responsive to only the low-complexity subset.

    摘要: To improve the shape coding of image sequences having differently coded VOPs with bidirectionally interpolated VOPs, the VOPs separated by a smaller time interval from the instantaneous bidirectionally interpolated VOP are used as the reference values for shape coding. This measure improves coding efficiency.
