    摘要: In one embodiment, a method receives a current picture of video content. The method then determines a set of reference pictures for the current picture and a temporal distance from the current picture for each of the set of reference pictures. A combined list of reference pictures in the set of reference pictures is determined where an order of pictures in the combined list is based on the temporal distance for each of the set of reference pictures to the current picture. The method then uses the combined list to perform temporal prediction for the current picture.

    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.
