ABSTRACT:
A decoding method and a decoder of a D-VHS codec system for recording/reproducing a high-definition picture and a high-fidelity sound is disclosed. In the playback of the digital data which is recorded in the format of the track, a decoding method and a decoder of the D-VHS codec system correct the random error or the burst error by the forward error correction addition information and reproduce both a high-definition picture and a high-fidelity sound. Consequently, an enormous quantity of computation which cannot be processed by programs, is performed in real time by an optimal data flow operation process method and the compressed or processed digital data is processed at a high speed. Also, a hardware configuration of the codec which conventionally includes two or three pieces of circuit board implements one custom-made semiconductor chip and cuts a unit cost of the manufacturing of the D-VHS codec.
