    摘要: In one embodiment, a method includes receives a prediction unit (PU) for a coding unit (CU) of video content. The PU is partitionable into a plurality of PU partition types. The method determines a PU partition type for the PU and a residual tree structure based on the PU partition type for partitioning of the CU into transform units (TUs). The residual tree includes a binary partition of a node into two. A TU partition for the PU partition type is determined based on the residual tree structure and a desired level of partitioning in the residual tree structure. The method then uses the TU partition in a transform operation.

    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 process performs a search on a base reference frame in a video signal to determine a first motion vector for each of the possible partitions of a current macroblock. The first motion vector for a partition provides the most optimal match for the partition in the base reference frame. An optimal partition for the current macroblock, which gives a minimum motion estimation cost among all the possible partitions in the base reference frame, is determined. The process performs the search on the optimal partition over a non-base reference frame in the video signal to determine a second motion vector that provides the most optimal match for the corresponding partition in the non-base reference frame. A simplified search is performed on each partition other than the optimal partition over the non-base reference frame to determine the second motion vector for the corresponding partition.
