Abstract
A video apparatus comprises a correction circuit for delaying a luminance stream in a digital stream. The correction circuit has a demultiplexer, a line buffer and a multiplexer to achieve this. This construction enables compensation of the luminance 2H-delay of conventional VHS and S-VHS signals. A process is disclosed for improving the picture quality of conventional VHS and S-VHS signals and for recording the corrected or quality-improved signals.
