Abstract:
Video data streams can be encoded and decoded using inter or intra prediction. The blocks of a frame can be processed based on depth, from the lowest level sub-blocks to the highest level large blocks, and divided into groups of blocks that are inter predicted, blocks having sub-blocks that are inter predicted and sub-blocks that are intra predicted, and blocks that are intra predicted. The inter predicted blocks are encoded or decoded first, followed by the inter predicted sub-blocks, the intra predicted sub-blocks, and the intra predicted blocks. Data from the inter predicted blocks and sub-blocks may be used to improve the prediction performance of intra predicted blocks and sub-blocks.

Claim (Index 1):
An apparatus for decoding a video stream, comprising:\n a decoder configured to perform a method comprising: determining prediction modes for blocks of a frame of the video stream, wherein at least some of the blocks are partitioned into levels of sub-blocks for prediction, each sub-block with a respective prediction mode; and decoding, in a scan order, the blocks of the frame at a level of the sub-blocks for a block by:\n decoding, using inter prediction, first sub-blocks, each first sub-block predicted using inter prediction or formed of lower-level sub-blocks each predicted using inter prediction, while skipping at least one of:\n a second sub-block comprising at least one lower-level sub-block predicted using inter prediction and at least one lower-level sub-block predicted using intra prediction; or \n a third sub-block predicted using intra prediction or formed of lower-level sub-blocks each predicted using intra prediction, wherein: \n \n the decoded first sub-blocks form a first group of inter predicted decoded blocks; \n decoding, using inter prediction, the at least one lower-level sub-block of the second sub-block predicted using inter prediction after decoding the first sub-blocks, to form a second group of inter predicted decoded blocks; \n decoding, using intra prediction, the at least one lower-level sub-block predicted using intra prediction of the second sub-block, after decoding the first sub-blocks; and \n decoding, using intra prediction, the third sub-block after decoding the first sub-blocks.
