Method and device for the processing of a composite colour video signal with an optimized memory capacity

摘要

The signal processing method involves using half of the frame images (A1,B1) of the PALplus signal, which are transmitted in letter box format. These are stored temporarily, for subsequent reconstruction at a multiple of the transmission frequency. Each half frame image is stored in different memory locations (M1,M2), so that the successive image lines are not stored in the sequential address locations.
