ABSTRACT:
In order to easily conduct channel switching and inter-channel mixing at the time of editorial operation without connecting an external device for channel switching or inter-channel mixing, the lap top type video recording and reproducing device includes two built-in audio two channel type video tape recorders, a built-in editorial means for editing between the two video tape recorders, and two audio monitors in one body. The device further includes, a signal selecting circuit for selecting either of a first state where the two channel audio signals reproduced by the video tape recorder are outputted from the same channels, a second state where the reproduced two channel audio signals are outputted from the opposite channels after channel switching, and a third state where the reproduced two channel audio signals are mixed to output the same signals from the both channels, and an input switching circuit for supplying output signals from the signal selecting circuit to the video tape recorder in place of two channel audio input signals inputted from the outside.
