摘要： In one embodiment, a method includes determining motion parameters for a temporally-located block to a current block of video content. The temporally-located block is located in a different picture from the current block. The temporally-located block is identified in a merge mode candidate list. The merge mode candidate list includes candidate blocks in which motion parameters are candidates to be used for the current block. The method then signals information to a decoder to indicate which motion parameters from a candidate block on the merge mode candidate list to use in decoding the current block. If a temporally-located block is identified, the method uses motion parameters for the temporally-located block in decoding the current block of video content.

摘要： In one embodiment, a spatial merge mode or a temporal merge mode for a block of video content may be used in merging motion parameters. Both spatial and temporal merge parameters are considered concurrently and do not require utilization of bits or flags or indexing to signal a decoder. If the spatial merge mode is determined, the method merges the block of video content with a spatially-located block, where merging shares motion parameters between the spatially-located block and the block of video content. If the temporal merge mode is determined, the method merges the block of video content with a temporally-located block, where merging shares motion parameters between the temporally-located block and the block of video content.

摘要： In one embodiment, a method determines a scaled motion vector for a first block. A motion vector for a second block is determined where the motion vector is on a non-uniform motion vector grid. The method then maps the motion vector for the second block to a higher accuracy uniform motion vector grid that is of a higher accuracy than the non-uniform motion vector grid and scales the motion vector for the second block on the higher accuracy motion vector grid. The scaled motion vector is mapped on the higher accuracy motion vector grid to the non-uniform motion vector grid. The scaled motion vector on the non-uniform motion vector grid is associated with the first block for a temporal prediction process.

摘要： Devices and methods that allow for applying a wavefront scan to rectangular transform blocks are described herein. Such devices and methods may allow greater efficiencies for entropy coding by enabling parallel processing of transform coefficients. In some embodiments, a method for coding a digital video sequence having a plurality of pictures includes dividing at least one of the plurality of pictures into blocks, performing a rectangular transform on at least one of said blocks to produce one or more transform coefficients, performing quantization on the one or more transform coefficients, and encoding the one or more transform coefficients, one at a time, along a coding scan order, to generate a compressed bitstream. The coding scan order may include a forward wavefront scan order or a reverse wavefront scan order and the quantization may result in producing quantized transform coefficients.

摘要： A method determines a plurality of interpolation filters for use in interpolating sub-pel values for a temporal prediction process of video content. The plurality of interpolation filters are designed based on sub-pel offsets for two reference blocks. The method determines a first sub-pel offset for a first reference block for the unit of video content and determines a second sub-pel offset for a second reference block for a unit of video content. A set of interpolation filters is determined to interpolate a set of sub-pel pixel values for use in the temporal prediction process for the unit of video content. The set of interpolation filters is designed for the first sub-pel offset and the second sub-pel offset and is used to interpolate a first sub-pel pixel value for the first reference block and a second sub-pel value for the second reference block.
