A system for generating an aesthetically pleasing abstract display on the screen of a color television receiver in timed relation to an audio signal derived from music or the like employs a filter network to divide the audio signal into a plurality of separate frequency bands. 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.

Color video display for audio signals

A text editing system is provided in which a central station communicates a video signal, timing signals, and control signal to a remote station by way of a single communication pathway for subsequent display on a cathode ray tube at the remote station and wherein keyboard information may be communicated from the remote station to the central station across the same communication pathway. The video signal from the central station includes conventional horizontal and vertical synchronization pulses which are encoded prior to transmission to the remote station and decoded at the remote station. In addition, the video signal is inhibited during both the horizontal and vertical synchronization pulses so that during the horizontal synchronization pulse, keyboard information from the remote station may be communicated to the central station across the communication pathway while during the vertical synchronization period control signals may be communicated from the central station to the remote station via the communication pathway.
