The digital video content comprises a stream of pictures, slices, or macroblocks which can each be intra, predicted or bi-predicted pictures. The pictures, slices, or macroblocks comprise blocks of pixels. The method comprises scanning frequency coefficients from each of the block's two dimensional array of frequency coefficients in a manner that is vertically biased.

摘要： In one embodiment, a spatial merge mode for a block of video content may be used in merging motion parameters. Spatial merge parameters are considered and do not require utilization of bits or flags or indexing to signal at the encoder or 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.

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： A method for processing a block of transform coefficients during intra coding includes receiving an N×M block of transform coefficients, wherein N is a row width of the block and M is a column height of the block. A first scan coding pattern is determined from a set of scan coding patterns comprising a diagonal scan coding pattern, a horizontal scan coding pattern, and a vertical scan coding pattern. The method further includes partitioning the N×M block into a plurality of sub-blocks each comprising a plurality of the transform coefficients; and processing the plurality of sub-blocks, one at a time, in a coding order along the first scan coding pattern to generate a bit sequence. The processing further comprises, for the sub-blocks containing at least one non-zero transform coefficient, coding at least the non-zero transform coefficients in a transform coefficient sequence along a second scan coding pattern.

摘要： A method and apparatus for processing an input image are disclosed. For example, the method receives a block of pixels from the input image, and selects a coding mode for the block of pixels based on at least one coding mode of at least one neighbor block of the block of pixels. The method determines whether the coding mode will result in all zero coefficients for the block of pixels, and selects the coding mode for the block of pixels if the coding mode will result in all zero coefficients for the block of pixels.
