Method and circuit for video signal correction

摘要

A video apparatus comprises a correction circuit (28) for delaying a luminance stream in a digital stream. The correction circuit has a demultiplexer (6), a line buffer (8) and a multiplexer (10) to achieve this. This construction allows to compensate for the luminance 2H-delay of conventional VHS and S-VHS signals. A process is proposed for improving the picture quality of conventional VHS and S-VHS signals. A video recorder recording the corrected or quality-improved signal is also proposed.
