Abstract: An apparatus for recording and reproducing a caption signal on and from an audio track of a video tape, used in a video tape recorder. The apparatus includes a microprocessor, a character buffer, a recording code converter, a linear audio recording/reproducing circuit, a mode selector, a reproducing code converter, a Hi-Fi audio recording/reproducing circuit, an audio output controller, a video signal processor, and an on-screen-display circuit, whereby the caption character signal is recorded and reproduced by the audio head on and from the audio track of the video tape.

Abstract: The present invention is a video signal controller which can operate in one of two modes; play back mode and recording mode. Each camera has its own assigned display monitor and address code sequence. During operation of the video controller, each video signal is combined with its corresponding address signal that identifies from which camera the video signal is originally generated. The video signal and each address signal are then recorded via VTR onto a video tape. When the video signal controller is in play back mode, it extracts the synchronization signal and address signals from signals outputted by the VTR. The address signal and synchronization signals are used to locate and identify proper monitor to display its corresponding segment of signals from the VTR. Each monitor then plays back only those signals generated from its corresponding camera.
