APPARATUS FOR CORRECTING DISTORTED SYNC IN A COMPOSITE VIDEO SIGNAL

A television receiver includes a "one-chip" television signal processing IC (200) which has a terminal for receiving a composite video signal including both image and synchronization pulse components. A composite video signal (105) 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 (100) of the "one-chip" IC (200) can reliably separate the synchronization pulses from the composite video signal after it has been non-linearly processed, a sync correction circuit (111), including an auxiliary sync separator (113), 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 (200).
