摘要
A microprocessor based decoder module for televisionvideo signals which have been encoded by suppressing sync pulsesand/or inverting picture video. The decoder module generatessync restoration gates and/or video inversion gates developedfrom timing signals present in the VBI of the encoded videosignal. The VBI timing signals may be either sync pulses whichare not suppressed during the VBI, or special timing signalsinserted at the video encoder. The microprocessor, in thedecoder module, may contain externally selectable programsegments where each segment will allow decoding of a differentvariety of video encoding.
