Abstract: PURPOSE:To easily discriminate the both track of a sound and an image by muting a video signal output according to the existence of a flag or a code, which is added to a sound signal, and muting a sound output in the other case. CONSTITUTION:A CPU 12 has function to discriminate the presence and absence of the flag or control code to be added to the sound signal and the presence and absence of an ID signal to be added to a video signal. When the flag or control code is detected in the CPU 12, since the track is the sound track, the mute of the video signal is loaded in a mute circuit 14 by a command from the CPU 12. On the other hand, when the ID signal is inputted to the CPU 12, the track is the image track and the mute of the sound signal is loaded in the circuit 14 by the command from the CPU 12. When the input of the ID signal is not executed in field recording, since the flag or control code is not detected by the CPU 12, the mute of the sound signal is loaded in the circuit 14.
