TH18507A - Television equipment with picture-in-picture - Google Patents

Abstract

A color television set contains a picture-in-picture builder. And interchangeable vertex circuits for providing the first vertex characteristic to the signal color component displayed when the main image shown is from the rectifier source. And for imparting the second vertex characteristic to the color component when the main image displayed is the image from the source, it helps by providing a reduction that results in the peaking error of the color signal when there is Picture show Overlap images from different sources

Claims (2)

1. Color TV receiver consists of Picture-in-picture generator that contains big picture builder, tiny picture generator And a combined switch that is connected to a generator for outputting the brightness and blended colors to be displayed for a small image area created by the thumbnail generator which is inserted within the image area to Created by a big visualizer An input switch with a first and second state for outputting the first and second image input to the entry point respectively of the big and small image generator And there is a second state for exchanging the image signal supplied to the replaceable filter circuit generator, which is connected between the switch color output point and the color signal input point of the display generator, that is, the color signal output circuit. Replaceable filters have a first-class operation for supplying the filter indicator. First to the mixed color signal when the first signal is supplied to the big image generator. And there is a second mode for supplying a second-order filtering characteristic to another mixed signal. 2. Color TV receiver, as described in claim 1, the receiver consists of an adjuster, an IF extender and a detector unit for delivering the first video signal to the input switch. Filtering characteristics First, it shows the slope response within the color bar. Filtering characteristics The second order shows a single, static response within a symbolic color scheme.
