ABSTRACT:
Non-orthogonality of the blanking region information caused by the 25 Hz offset in a digital PAL-encoded color television signal is corrected by a dynamic offset circuit. To this end, a plurality of waveforms describing the envelopes of the blanking, sync and burst are stored, and during video signal processing are sequentially addressed at a 25 Hz rate. The resulting assembled output blanking information is orthogonal to the television scanning frequency.
