Automatic colour control system for colour TV receiver - adjust image luminance, contrast and chrominance by monitor in transmission station

摘要

The automatic colour television control system uses a transmission monitor for the image luminance, contrast and chrominance setting. The set parameters are coded and transmitted with the video and audio components to the receivers, whose colour is thereby automatically adjusted. The receiver has a microprocessor to convert the received parameter codes into optimum signals for adjusting the image in a continuous process.
