TRANSMISSION AND RECEPTION OF ENCODED VIDEO PICTURES

摘要

An advanced video compression coding system which employs variable block size transforms to improve the compression efficiency for transmission of video pictures. A picture block 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 and on the basis of block size. A block-size code is skipped when the scanning pattern intersects a block which has already been scanned earlier. The series of block-size codes is then run-length and Huffman-coded before being transmitted.
