A new video signal processor for high-end professional LaserVision CD video players

摘要

An integrated circuit (IC) is described that is designed to process the signal from the photodiode in a LaserVision or compact disk (CD) video player directly into a CVBS signal suitable for a color TV receiver. The bipolar IC requires about 45 mA from a 5 V supply and incorporates the following features: modulation transfer function (MTF) compensation, de-emphasis, dropout compensation, noise reduction, separation of signals for timing control, picture insertion, a data slicer, and a NTSC/PAL system selector.
