TRANSMISSION AND RECEPTION OF ENCODED VIDEO PICTURES

摘要

An advanced video coding system is disclosed, which employs variable-size transforms to improve the compression efficiency. The segmentation map is transmitted as a one-dimensional series of block-size codes by scanning the segmentation map in accordance with a predetermined scanning pattern on the basis of the smallest block size. A block-size code is skipped when the scanning pattern intersects a block which has already been scanned earlier (most blocks are larger than the grid). The series of block-size codes is then run-length and Huffman-coded.
