Television signal transmitting system and processing apparatus.

摘要

Picture images which have an aspect ratio of 4:3 or larger are transmitted as main signals (M1 to M180) in a central main panel of the picture frame of a conventional system. A processing operating using the correlation of vertically adjacent scanning line signals is applied with respect to signals based on a wide television system for transmitting helper or reinforcement signals (S1 to S60) for improving the picture quality of the main signal and providing these signals in upper and lower panels. Cross talk caused between the main signals and the helper signals located in the upper and lower panels next to the main panel cause degradation of the picture quality. The present invention prevents cross talk from being caused, or makes its influence on the picture quality inconspicuous. The transmission system locates a signal (S30, S31) having a large correlation with the helper signal between the main panel, and the upper and lower panel or locates a signal (S1, S60) at the locations next to the main panel so that any picture degradation generated by cross talk is hidden by the over-scans of the display apparatus.
