Abstract
A television receiver includes a 'one-chip' television signal processing IC which has a terminal for receiving a composite video signal including both image and synchronization pulse components. A composite video signal which has been non-linearly processed by a so-called 'black-stretch' circuit is coupled to the composite video signal input terminal of the 'one-chip' IC. In order that a sync separator of the 'one-chip' IC can reliably separate the synchronization pulses from the composite video signal after it has been non-linearly processed, a sync correction circuit, including an auxiliary sync separator, is used to modify the synchronization pulses of the composite video signal after it is non-linearly processed and before it is coupled to the 'one-chip' television IC.
