ABSTRACT:
High definition television coder/decoder a high definition coder or decoder includes a number of parallel sub-decoders or coders. The image to be coded or decoded is divided into a number of stripes, a given stripe being coded or decoded by a single sub-coder or sub-decoder. Every N.sup.th stripe is coded or decoded by the same sub-coder/sub-decoder, where N is the number of sub-coders or sub-decoders. The number of sub-coders is independent of the number of sub-decoders whereby a reduction in the number of sub-coders with increasing bit-rate capacity does not necessitate a change in decoder.
