  • Method of simultaneously recording dynamic digital data, an analog audio signal and a video signal
    Patent number: 5327231
    Abstract: A method of simultaneously recording a signal indicative of dynamic digital data, and signals comprising the analog voice and video picture data of a television signal is disclosed. The dynamic digital data is encoded into a signal at audio frequencies between a lower threshold frequency and an upper threshold frequency. The analog audio signal is filtered to remove frequencies between the lower threshold frequency and the upper threshold frequency. The encoded digital data signal and the filtered analog audio signal are combined into a single analog audio signal. The combined audio signal and the video signal are video recorded into a television signal.
