Abstract

In the picture-in-picture (PIP) of a color TV set Color burst pulse for extracting the color burst of the video signal that matches the main picture. It is generated in response to the synchronization pulses along the plane received by the receiver sector of the TV receiver. Color bursts are applied to receive the carrier signal. Sub-color for recursive modulation of the base band color component corresponding to the thumbnail picture. Synchronization pulses along the plane Related to It is then furthered to the PIP sector to locate the appropriate smaller images relative to the main image. Even if the center is aligned along the plane, for the proper positioning of the color burst pulse, a bursgate pulse delay control signal is generated. It responds to the relationship between the position of the horizontal synchronization pulses in relation to the plane synchronization and pulses of the video signal. Corresponding to the main picture, the color pulse delay signal will be generated useful by the micro-base processor TV control unit. Which will accept both synchronization pulses along the corresponding plane relative to the And video for on screen and is intended to be used to control the respective tuning.
