摘要： To reduce noise or the like generated at a boundary of tiles introduced in a video coding method. In a motion vector detection unit, a first tile video signal and a second tile video signal included in one picture are supplied to a first detection unit and a second detection unit, and a reference image is supplied from a frame memory to the first detection unit and the second detection unit. The first detection unit performs processing, by inter prediction, on the video signal positioned on or in the vicinity of a tile boundary between a first tile and another tile among many video signals included in the first tile. In this processing, the first detection unit generates a motion vector so as to preferentially refer to the reference image included in another tile different from the first tile among the reference images read out from the frame memory.

摘要： For a decoding apparatus based on H.265/HEVC with single-core or single-threaded hardware not parallelized, which executes decoding a plurality of tiles and filtering around a tile boundary, the disclosed invention is intended to reduce the frequency of access to decoded data around the boundaries between tiles stored in a frame memory for filtering such data or reduce the circuit size of a buffer that retains decoded data around the boundaries between tiles. The image decoding apparatus disclosed herein executes decoding and filtering in raster scan order across a screen independently of the sizes and positional relations of tiles. At a tile boundary, decoding proceeds to a right adjacent tile on the same row, rather than decoding coding blocks on one row down in the same tile, and filtering is also executed using decoded data of row-wise adjacent coding blocks.
