Video decoding device, video decoding method, video decoding program, and video decoding integrated circuit |
摘要 |
With use of a simplified program or calculating device for motion compensation, a video decoding device decodes video data compressed by motion detection operations on macroblock units, as in the MPEG-4AVC standard. The video decoding device splits compressed data blocks of the prescribed size, 16×16 pixels for instance, to generate sub-blocks, which are smaller than the blocks and on which the video decoding device is able to execute motion compensation operations. The video decoding device duplicates a motion vector assigned to a given block to generate as many motion vectors as there are sub-blocks in the given block, and executes motion compensation on each sub-block using the corresponding duplicate motion vector. Data resulting from the motion compensation operation on each sub-block is combined to obtain a target block corresponding to the given block. |
