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.
