  • System for recording and/or transmitting binary information at a high data rate via known means for recording and/or transmitting video information, and for decoding the digital data
    Patent number: 5019914
    Abstract: A method and an apparatus encode and decode binary signals representative of digital information onto or from a high frequency carrier wave. The carrier wave replaces the chrominance signal of a composite video signal. Encoding and decoding of the binary signals are by phase modulation and demodulation of the carrier wave. The method and apparatus allow simultaneous transmission of both the binary signals and the monochrome portion of the composite video signal. The apparatus can be configured to serve as an interface between a mini-computer and a composite video recorder, so that the composite video recorder can be used as a mass storage peripheral.
