Abstract
Audio signals and digital commands are encoded into a standard raster format television signal recorded on a casette for play by a home video cassette unit. The audio signals are encoded in the displayable video as modulated carrier pulses separated by return to median intervals with the audio waveforms being tapered near discontinuities. The digital commands are recorded as binary level pulses, one such pulse occupying substantially an entire video line to permit accurate decoding.
