Coding method and coder of a D-VHS codec system using forward Reed Solomon error correction

摘要

A coding method and a coder of a D-VHS codec system for recording/reproducing a high-definition picture and a high-fidelity sound is disclosed. In the recording of digital data which is compressed or processed, the coding method and the coder of the D-VHS codec system record digital data with forward error correction addition information in the format of a track for a forward error correction. 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.
