Abstract
The present invention relates to an apparatus and method for processing a picture-in-picture video signal for PIP display of a compressed sub-picture displayed within a main picture on advanced TV receivers. More particularly, the present invention relates to the apparatus and method for processing a PIP video signal of advanced TV systems which use real video data lines, as opposed to artifically generated lines of video data, as the interleaving line to interleave the present field being compressed, when vertically compressing a sub-picture video signal. Accordingly, the present invention provides a hardware of simple constitution and a PIP display with advanced resolution.
