摘要： In one embodiment, a method receives a unit of video content. The unit of video content is coded in a bi-prediction mode. A motion vector predictor candidate set is determined for a first motion vector for the unit. The method then determines a first motion vector predictor from the motion vector prediction candidate set for the first motion vector and calculates a second motion vector predictor for a second motion vector for the unit of video content. The second motion vector predictor is calculated based on the first motion vector or the first motion vector predictor.

摘要： A method for processing a block of transform coefficients during inter coding includes receiving, during inter coding, 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. 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 a first diagonal scan coding pattern to generate a bit sequence corresponding to the N×M block. The processing 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 diagonal scan coding pattern.

摘要： A method and system of transform-based encoding, decoding, and bitstream generation of digital video content is disclosed. 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 and system comprises scanning frequency coefficients from each of the block's two dimensional array of frequency coefficients in a manner that is vertically biased, producing a one dimensional array of frequency coefficients. The method and system also provide for scanning/assigning frequency coefficients from a one dimensional array of frequency coefficients, producing a two dimensional array of frequency coefficients.
