ABSTRACT:
A picture in picture video signal processing circuit does not need an extra synchronization generator because sub picture video signals are synchronized with the main picture video signals by storing decoded sub picture video signals in a memory then reading the decoded sub picture video signals out in response to synchronization signals of the main picture video signal. Further, the memory can be of a lower capacity owing to the fact that the synchronization signals of the sub picture video signal are not stored.
