Digital audio data reproduction apparatus

摘要

A digital audio data playback apparatus such as a digital audio disc player is configured such that a PCM encoder and associated circuits within the apparatus can be used both for playback of recording discs having only digital audio data recorded thereon and also for processing a digital audio signal output from a video disc player during playback of a video recording disc having digital audio data recorded thereon, superimposed upon frequency-modulated recorded audio and video data. This eliminates the need to provide a PCM encoder circuit within such a video recording disc player.
