A method and apparatus are provided for performing overlap transform and deblocking of a decompressed video signal. The video image is sub-divided into a plurality of non-overlaping macroblocks, each of which comprises a plurality of smaller sub- blocks. Each macroblocks comprises two luminance partitions and one chrominance partition. Each partition is buffered and further buffering is provided for sub-blocks of each partition. Overlap transform and deblocking are performed by buffering sub-blocks from current partitions and sub-blocks from partitions from adjacent macroblocks. Overlap transform is performed in the current macroblock for buffered sub-blocks and deblocking is performed for blocks in the adjacent macroblocks. |
