<P>PROBLEM TO BE SOLVED: To provide the video signal processing apparatus which allows blanking main and auxiliary images in a multi-image display, e.g., a PIP or POP display. <P>SOLUTION: In the video signal processing apparatus, the blanking is part of a V-chip feature and the blanking occurs in response to auxiliary information such as XDS data, which is included in a video signal to indicate a content of television programming. Main image blanking occurs only during effective video intervals, to prevent degradation of a sync information. In a system that generates the main image from various types of video signals, e.g., composite video and S-video signal, that require separate signal processing paths, main image blanking capability is provided in one signal path only, e.g., a composite video signal path. The blanking capability is activated, the associated signal path is selected, and main image blanking is performed regardless of types of signal that generates main images. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
