Audio-visual information signal reproducing apparatus that mutes output audio upon input audio signal interruption

Image Number 18 for United States Patent #5400305.

An audio visual information signal reproducing apparatus reproduces an audio visual information signal from a recording medium, the audio visual information signal being recorded on the recording medium and composed of a video signal and a digitized audio signal being time-division multiplexed in such a way that the frame interval of the video signal does not accord with the frame interval of the digitized audio signal. The apparatus sets an audio output mute flag of a control code contained in the digitized audio signal of the audio visual information signal being reproduced and shifts to a next operation mode when a normal play mode is interrupted.
