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： Embodiments for high efficiency low complexity interpolation filters for High Efficiency Video Coding are disclosed herein, specifically novel techniques for a video compression system. In order to estimate and compensate sub-pel displacements, the image signal on these sub-pel positions is generated by an interpolation process. In HEVC, sub-pel pixel interpolation is performed using filters. Generally, the filter may have 8 taps to determine the sub-pel pixel values for sub-pel pixel positions, such as half-pel and quarter-pel positions. The taps of an interpolation filter weight the integer pixels with coefficient values to generate the sub-pel signals. Different coefficients may produce different compression performance in signal distortion and noise.

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 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.

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.
