Abstract

Apparatus for encoding/decoding a HDTV signal for e.g., terrestrial transmission includes a compression circuit responsive to high definition video source signals for providing ierarchically layered codewords CW representing compressed video data and associated codewords T, defining the types of data represented by the codewords CW. A priority selection circuit, responsive to the codewords CW and T, parses the codewords CW into high and low priority codeword sequences wherein the high and low priority codeword sequences correspond to compressed video data of relatively greater and lesser importance to image reproduction respectively. A transport processor, responsive to the high and low priority codeword sequences, forms high and low priority transport blocks of high and low priority codewords respectively. Each transport block includes a header, codewords CW and error detection check bits. The respective transport blocks are applied to an forward error check circuit for applying additional error check data. Thereafter the high and low priority data are applied to a modem wherein they quadrature amplitude modulate respective carriers for transmission.
