Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] A method for multiplexing video input and component input interfaces in a television receiver. The video signal includes one video signal and two left and right audio signals, and the component signal includes one luminance signal and two color difference signals. At present, the Both the input terminals of video signal and component signal use RCA type interface, so it is completely possible to combine the input terminals of the two signals and share one terminal to achieve the purpose of reducing a group of terminals.

[0015] The method comprises the steps of:

[0016] 1.1) Each of the three signals of the video signal is provided with an input terminal, and each of the three signals of the component signal shares an input terminal of the video signal; among them, the video signal in the video signal is shared with the luminance signal in the component signal...

Abstract

A method for multiplexing video input and component input interfaces in a television receiver, the video signal includes one video signal and two left and right audio signals, the component signal includes one luminance signal and two color difference signals; the same group of RCA signal terminals is used , through the signal channel switching circuit, the common use of video signal and component signal input terminals is realized. On the premise of ensuring the number of signal channels, the number of signal input terminals is greatly reduced, and the structural requirements of the flat panel TV are met.

Description

technical field [0001] The invention relates to the field of television input interfaces, in particular to a method for multiplexing video input and component input interfaces in a television receiver. Background technique [0002] With the continuous updating of display technology, household TVs are constantly developing towards thinner and flatter trends. A new generation of flat panel TV represented by LCD TV has replaced the traditional CRT TV and has become the mainstream of TV development. While emphasizing the beautiful appearance, various consumer video and audio playback devices represented by set-top boxes, DVDs, and media players have entered ordinary homes and are becoming indispensable "peripherals" for home TVs. The user's demand for the number of TV source interfaces continues to increase, and a single AV (video) or YPBPR (component) source interface is difficult to meet the needs of current users, and it is necessary to add multiple sources of multiple forma...
