Abstract
A signal recording apparatus for recording a TV signal in which an audio signal such as a MUSE signal and a video signal are multiplexed in a time sharing manner in units of a given period of time, is arranged to code these video and audio signals alike, to dispersively allocate a discretely separated audio signal within the video signal, to provide symbols other than the symbols of the audio and video signals within each synchronizing block for the purpose of permitting the use of other video signal recording apparatuses. The arrangement permits simplification and high-quality of the apparatus for recording the signals of this kind and thus contributes to the popularization of the apparatus.
