ABSTRACT:
A video signal compression system provides compressed video data in groups of frames and divides the compressed video data between high and low priority channels according to a predetermined hierarchy of compressed video codeword types. The fraction of data to be applied to the respective channels is not determined by the ratio of the data handling capacity of the two channels, but rather on a frame by frame basis in accordance with the actual channel capacity remaining for the respective group of frames.
