ABSTRACT:
Television signal processing apparatus act on a received standard-bandwidth television signal to produce a high-definition-like video image relatively free of artifacts. A motion-adaptive line doubler operates in combination with a non-linear enhancer. In a practical implementation, the combination further includes a digital decoder. When the output of the decoder is applied to the line doubler, an interface provides a transition from the time base of the decoder to the time base of the line doubler. The non-linear enhancer includes bandwidth expanding enhancement for horizontal and/or vertical picture transitions.
