Abstract

PURPOSE:To simplify the circuit constitution of VTR by enabling the constitution to provide sound multiplex signal reception in recording mode and sound multiplex signal transmission in reproduction mode. CONSTITUTION:This circuit is provided with a circuit that FM-demodulates and modulates a sub-channel signal. Further, a matrix and signal switching circuit are provided which are so formed that while a signal which can be supplied to a sound recording circuit side is outputted by receiving a main-channel signal and sub-channel signal in recording mode, signals in the same states with the main- channel signal and sub-channel signal can be outputted. In addition, the titled circuit is also provided with a control-signal detecting and generating circuit that can detect a control signal in recording mode and generate the control signal in reproduction, a method of mixing the control signal with signals obtained by modulating the main-channel signal and sub-channel signal in reproduction, and another method of switching the above-mentioned circuit and method in response to the switching operation between the recording and reproduction modes.
