ABSTRACT:
Apparatus is provided for the control of a video tape or cassette recorder by a microcomputer. The apparatus is interfaced to the video recorder for the input and output of various control signals via the remote control connector of the video recorder. The apparatus also includes interconnections to a microcomputer, a monitor and the audio and video signals of the video recorder. The apparatus under the control of the microcomputer controls operation of the video recorder and selectively supplies either video recorder video or microcomputer video to the monitor and independently supplies one of the two audio channels of the video recorder or no audio to the monitor. The apparatus under keyboard inputs from the microcomputer controls transport functions of the video recorder including rewind, fast forward, various play speeds, stop and pause. The apparatus also controls random access and presentation of addressable frame segments and locations of a video tape or cassette and maintains an accurate frame count throughout various transport functions with respect to an accurately defined starting point.
