Video signal defect compensation system

摘要

A video signal defect compensation system is adapted to display an image on a video monitor without interruption. A video signal defect compensation device is adapted to reproduce a video signal, for a restricted time interval, from a memory medium on which a desired video program is recorded, and a video signal generator is adapted to continuously generate a predetermined video signal. Through a switching circuit, a video signal is selectively supplied from the video signal reproducing device or video signal generator to the video monitor. The switching circuit is controlled by a means for detecting whether or not the video signal reproducing device produces an output, and supplies a video signal to the video monitor while the video signal defect compensation device delivers the video signal, and supplies a video signal from the video signal generator to the video monitor while the video signal from the video signal reproducing device is interrupted.
