Abstract

The luminance signal (Y) generally has a greater bandwidth and therefore a shorter transit time than the chrominance signal. To compensate this difference in transit time, a retardation stage must be provided in the path of the chrominance signal (Y). For a luminance signal of high bandwidth, this is a relatively complex and costly component. The aim is to simplify this harmonization of the transit times of luminance signal and chrominance signal. To equalize the transit times, instead of the luminance signal being retarded, the chrominance signals are read at higher speed from memories (M2, M3) during a time interval which is not visible in the picture. The present invention is particularly suitable for image storage devices for HDTV sets with high picture frequency and/or line frequency.
