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： In various embodiments, a significance map of a matrix of video data coefficients is encoded or decoded using context-based adaptive binary arithmetic coding (CABAC). The significance map scanned line-by-line along a scanning pattern. Each line may be a vertical, horizontal, or diagonal section of the scanning pattern. Context models for each element processed in a particular line are chosen based on values of neighboring elements that are not in the line. Avoiding reliance on neighbors that are in the same line facilitates parallel processing.
