ABSTRACT:
Apparatus for decoding an HDTV signal conveyed as high and low priority data in high and low priority channels respectively, wherein said high and low priority data originated from blocks of hierarchically encoded compressed video data, with data of greater importance for image reproduction from each block allocated to the high priority channel and the remaining data from each block allocated to the low priority channel, includes circuitry for identifying and segmenting high and low priority data for corresponding blocks and recombining the high and low priority data into an hierarchically encoded compressed video data stream.
