Abstract:
Tile copying may include decoding a current frame from an encoded video bitstream by decoding, from the encoded video bitstream, tile information for a current tile of the current frame. Decoding the tile information for the current tile of the current frame includes decoding a reference tile offset, and the tile information for the current tile omits encoded tile content information corresponding to the current tile. From the encoded video bitstream, encoded tile content information corresponding to the reference tile is identified based on the reference tile offset, a decoded tile corresponding to the current tile is generated by decoding the encoded tile content information corresponding to the reference tile as the current tile, and the decoded tile is output or stored.
