发明名称 RECORDING AND REPRODUCING DEVICE OF VIDEO SIGNAL
摘要 PURPOSE:To obtain a distinct reproduced monitoring sound, by compensating the reproduced FM signal which is dropped out by the disturbance of the recording signal in the stage of after-recording by the output of a delay circuit. CONSTITUTION:A delay circuit 18 which delays a reproduced FM audio signal by the time duration of the recording section of a PCM audio signal and a changeover switch 20 which selects the reproduced FM audio signal and the output of the delay circuit 18 are provided. Said circuit and switch are so constituted that the switch 20 can be changed over to the output side of the circuit 18 in the recording section of the PCM audio signal in the stage of recording the fresh PCM audio signal in the recording part of the PCM audio signal while reproducing the video signal and the FM audio signal, whereby the reproduced monitoring sound which is beforehand corrected with the delay output is obtained.
