ABSTRACT:
A memory-based television receiver includes an apparatus for generating a composite sync signal CSS for timing the memory reading operation and the deflection circuits of the receiver. The horizontal sync components of the internally-generated composite sync signal are locked to the system clock. The vertical sync components of the internally-generated composite sync signal are, on the other hand, locked to the vertical sync components of the incoming video signal.
