Abstract: An audio to video translator in which an RF oscillator having a frequency within the commercial television broadcast band is coupled to the antenna terminals of a commercial home television receiver and tuned to the selected channel with no other antenna terminal input. The RF oscillator is modulated with vertical and horizontal sync pulses together with the outputs of a color oscillator which in turn is modulated by incoming audio such as from a standard stereo receiver tape deck or record player. Blanking and unblanking pulses from the output of a video generator also modulate the RF oscillator, the video generator being frequency modulated by outputs from the sync pulse generators and the audio channels.
