Embodiment Construction

[0019] The present invention will be exemplified according to the best embodiment of the present invention, but it should not be considered that the present invention is limited to them in any form. For example, a television receiver will be illustrated, but the present invention can also be applied to other types of video processing systems with display devices, such as televisions, DBS signal receivers, and VCRs. Closed captioning will be illustrated, but the present invention can also be applied to other XDS data. The PiP is illustrated, but the present invention is also applicable to PoP and picture be side picture.

[0020] 1. Receiver with AP

[0021] A television receiver having a display 108 driven by a signal received from a multiplexer 107 is illustrated in FIG. 1. The multiplexer receives the main picture signal 105 from the tuner (the tuner in turn receives the signal from a signal source such as an antenna or a cable system), and either receives auxiliary signals from...

Abstract

A television set having the option of displaying main and one or more auxiliary pictures, ratings control capability which includes means for an authorized person to limit the display of programs having ratings beyond a selected level, closed captioning capability which includes means for a viewer to choose to display closed captioning along with a picture, and a single stripper for slicing data from the vertical blanking information (VBI) portion of one or more broadcasts wherein the single stripper processes ratings control information for both main picture and auxiliary picture when the ratings control option has been invoked by cycling between main and auxiliary; and the auxiliary picture capability is disabled when the closed captioning option has been invoked.

Description

Technical field [0001] The present invention relates to a video signal processing system, which has optional "V_chip" ("image chip") level control (RC), optional display of auxiliary information such as closed caption (CC) display, and simultaneous display of the main picture (or Image) and one or more auxiliary images (or images). Background technique [0002] A video signal processing device that processes and generates a signal suitable for coupling to a display so as to generate a display having a main image and an auxiliary image (ie, a multi-image display) according to the viewer's selection is well known. The term "video signal processing equipment" or "video signal processing system" as used herein is used to include various types of video signal processing equipment, including, but not limited to, television signal processing equipment that may or may not include a display. Examples of these devices include televisions, television receivers, direct broadcast satellite (D...
