Multisource output television

Abstract

The invention discloses a multi-source output television, comprising a main processing chip and an intermediate frequency amplifying chip, and provided with a first SCART interface and a second SCART interface, the first SCART interface is used for receiving a video signal output by the intermediate frequency amplifying chip and / or an audio signal output by the main processing chip, and is able to invariably output certain program source signal, e.g. cable television signal; the second SCART interface is used for receiving the video and / or audio signals output by the main processing chip, and is able to output diverse program source signals in accordance with diversity of the output sources, e.g. the cable television signal or AV signal. Therefore, the inventive television can realize simultaneous output for the diverse program sources and, in addition, diverse selectability of the programs.

Description

technical field [0001] The invention relates to a multimedia device, in particular to a multi-source output television. Background technique [0002] With the rapid development of multimedia technology, TV has become the main electronic product for home entertainment. Appareils Radiorecepteurs et Téléviseurs), etc. Among them, the SCART interface is a special audio and video interface developed by the French company Peritel, and it is also an interconnection interface for satellite TV receivers, TV sets, video recorders and other audio and video equipment that is mandatory in Europe. Through the SCART interface, consumers can freely connect different audio and video signal transmission equipment. [0003] Current TVs are mainly classified into cathode ray tube (Cathode Ray Tube, CRT) TVs, LCD TVs, plasma TVs, etc., which are generally configured with one or two SCART interfaces. [0004] figure 1 It is the circuit diagram of the TV output video signal with two SCART inte...

AI Technical Summary

Problems solved by technology

[0007] The defect of this technology is that the output signals of the SCART1 and SCART2 interfaces are the same, when a TV (Television, television) program source is input into a TV, such as a cable TV (Cable TV) program source, the signals sent by these two SCART interfaces are all TV Signal, when there is an AV (Audio Video, audio and video) program source input into the TV, such as a digital video disc (Digital Video Disk, DVD) program source, the signals sent by the two SCART interfaces are all AV signals, and when the TV program source When the AV program source is input to the TV at the same time, the signals sent by the two SCART interfaces can only be TV program sources or AV program sources, and the two SCART interfaces cannot output different program sources, so that the TV cannot simultaneously output different program sources.

[0008] In summary, there are obviously inconveniences and defects in the actual use of televisions of the prior art, so it is necessary to improve them.
