Circuit for synchronizing an on-screen-display (OSD) on a picture screen.

摘要

During OSD on a picture screen (3) flicker and jitter arise within in the reproduced characters due to incorrect reference signal H and V. It is an object of the invention to modify the circuit in such a way that said flicker and jitter within the reproduced picture are reduced. Horizontal sync. pulse H and vertical sync. pulse V for the OSD processor (1) are derived from a super sandcastle pulse (SSC). Especially for a television receiver having OSD. <IMAGE>
