INTERACTIVE VIDEO PRODUCTION SYSTEM AND METHOD Abstract of the Disclosure The present invention relates to an interactive video production system. The system is comprised of an analog video storage unit which stores a composite video signal having red, blue and green video components and having an associated video information content and provides as a video output signal the composite analog color video signal at a real time video frame rate. A decoder is connected to the storage unit for receiving the composite analog color video signal and for decoding the signal into the red, blue and green analog video components. The decoder is capable of providing decoded red, blue and green analog video components as separate red, blue and green analog video output signals at the real time video frame rate. A real time video processor is connected to the decoder for receiving the red, blue and green video output signals. The processor includes a digitizer which digitizes the red, blue and green video output signals and digitally processes those signals in a 4:3 aspect ratio configuration of active pixels. A real time interactive unit is connected to the processor for enabling real time interactive controllable digital processing of the associated video information content of the digitalized red, blue and green signals on an active pixel-by-pixel basis by the processor. The processor further includes a unit for providing corresponding red, blue and green analog video output signals from the digitally processed red, blue and green video output signals. An encoder is connected to the processor for receiving the corresponding red, blue and green analog video output signals and for providing a composite interactively processed analog color video signal.
