Coding system for digital audio disc record

摘要: Digital audio data to be recorded in a pseudo-video format on disc record is applied an error check encoder that encodes each line of with code. The preset initial state corresponding recording track number prior encoding line. changed periodically during whereby information conveyed by the form code without requiring additional bits lines. Upon playback disc, encoded decoder expected number. decoding, errors recovered are corrected and recovered. numbers compared provide correction signal tracking may line-by-line basis within field need for data.
