ABSTRACT:
An interactive video display system is disclosed for communicating with local viewers. The system includes a receiver for receiving a modulated signal carrying related audio and video information. A video and audio control is operatively connected to the receiver for receiving the modulated signal and separating the signal into a video signal and an audio signal. A video display monitor is connected to the control for receiving the video signal and displaying the video information carried by the video signal. A radio transmitter is connected to the control for receiving the audio signal and transmitting a radio frequency signal at a select frequency so that the audio information related to the video information can be received by viewers proximate the video display system. An interactive control is operatively associated with the video and audio control for generating instructions to be displayed, the video and audio control combining the received instructions with the received video information prior to transferring the video signal to the video display monitor.
