Abstract:
1. A video decoding device that performs decoding processing on blocks of a compressed video, the decoding processing including motion compensation processing, the video decoding device comprising: a memory that stores reference pictures; a compensation unit (i) that includes an input buffer for storing one or more of the reference pictures, the input buffer having a capacity that sufficiently stores reference pictures corresponding to two blocks, and (ii) that sequentially performs the motion compensation processing block by block with reference to the reference pictures stored in the input buffer; and a reference picture transfer unit that sequentially transfers reference pictures corresponding to two adjacent blocks from the memory to the input buffer included in the compensation unit such that (i) reference pictures corresponding to a first block from among the two adjacent blocks are transferred during a first two consecutive predetermined time periods and (ii) reference pictures corresponding to a second block from among the two adjacent blocks are transferred during a second two consecutive predetermined time periods, wherein the first two consecutive predetermined time periods and the second two consecutive predetermined time periods overlap each other by one predetermined time period.
