These signals are provided to the inputs of three modulators along with video pattern signals developed by a digital/analog mapping network connected to the outputs of various stages of an oscillator driven counter chain. The same counter chain produces the horizontal and vertical synchronization signals for the receiver so that the display is generated in timed relation to the raster scan of the television receiver. The three modulators receive certain of the audio signals and certain of the analog signals and their outputs are provided to the three chrominance inputs of the receiver either directly or via an RF transmitter which allows connection to the antenna of the TV set. | |
