摘要： Video coding using tiling may include encoding a current frame by identifying a tile-width for encoding a current tile of the current frame, the tile-width indicating a cardinality of horizontally adjacent blocks in the current tile, identifying a tile-height for encoding the current tile of the current frame, the tile-height indicating a cardinality of vertically adjacent block in the current tile, and generating an encoded tile by encoding the current tile, such that a row of the current tile includes tile-width horizontally adjacent blocks from the plurality of blocks, and a column of the current tile includes tile-height vertically adjacent blocks from the plurality of blocks. Encoding the current frame may include outputting the encoded tile, wherein outputting the encoded tile includes including an encoded-tile size in an output bitstream, the encoded-tile size indicating a cardinality of bytes for including the encoded tile in the output bitstream.

摘要： Decoding a video sequence may include generating decoded video data by decoding encoded video data from an encoded bitstream, wherein decoding the encoded video data includes identifying candidate reference motion vectors used to decode previously decoded blocks, identifying reconstructed pixel values from a block spatially adjacent to a current block in the current frame, for each candidate reference motion vector, determining a respective score based on a difference between the reconstructed pixel values and pixel values obtained using the candidate reference motion vector, identifying a candidate reference motion vector having the minimal score from the candidate reference motion vectors as the reference motion vector, decoding a motion vector from the encoded bitstream using the reference motion vector, and decoding the current block from the encoded bitstream using the motion vector.
