Description
Technical field
The utility model is related to signal converting technical fields, and in particular to a kind of vision signal pinboard.
Background technology
AV interfaces, also known as compound interface, transmit mixed video signal, and signal fidelity is relatively preferable；USB interface is aobvious
The interface type being most widely used on card, most of video card all carry such interface；HDMI is that occur in recent years and fast
The interface of speed development, can transmit high-definition digital video signal, can transmit uncompressed video signal；HDMI often can be used for machine top
Box, DVD player, PC, holder for TV playing, integrated amplifier, numerical digit sound equipment and television set.
Signals Transfer Board is a kind of for introducing or drawing signal to facilitate the electricity for connecting various instruments or providing signal source
Road plate.Setting signal pinboard can facilitate signal to transmit between switching device and current-variable controller as a result,.Still have one at present
A little old-fashioned TVs do not have high-definition interface or television decoding ability limited.Also there are various video adapting equipment on the market, but turns
Signal, the interface changed is relatively simple, is also less able to the equipment for being converted into TS streams.
Utility model content
In view of the above-mentioned problems, the utility model is intended to provide a kind of vision signal pinboard.
To realize that the technical purpose, the embodiment of the utility model be：
A kind of vision signal pinboard, including signal receive chip TSUMV56RU, signal conversion chip LT8918 and signal
Pio chip MCS8428Q, the signal conversion chip LT8918 are connected with signal source module, signal switching module, audio and video
Signal exports LVDS vision signals and left and right audio signal, left and right audio letter after receiving chip TSUMV56RU decodings via signal
It number is fed directly to signal pio chip MCS8428Q, LVDS vision signal and is converted into MIPI letters via signal conversion chip LT8918
It number send to signal pio chip MCS8428Q.
MIPI signals and left and right acoustic channels audio signal are decoded coding by the signal pio chip MCS8428Q again, and one
Road is encoded into TS streams by AV mouthfuls of output audio and video, another way, flows signal by SDIO mouthfuls of output TS.
The TS stream signals, which export, gives next stage SOC decoding chips, is converted with completing the unified of audio-video signal.
The signal source module include VGA, the first AV mouthfuls, USB multimedias, HDMI1, HDMI2 and HDMI3.
The signal switching module includes button switching information source and IR remote control switching information sources.
The beneficial effects of the utility model can access various video signal and output various video signal, can facilitate
Flexible selection incoming video signal interface and output video signal interface, decoding capability is stronger, and audio and video lossless can be converted
It is flowed at TS.
Description of the drawings
Fig. 1 is the circuit connection diagram of the utility model.
Specific implementation mode
The utility model is described in further details in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, specific embodiment described in the utility model is a kind of vision signal pinboard, including signal receives
Chip TSUMV56RU, signal conversion chip LT8918 and signal pio chip MCS8428Q, the signal conversion chip
LT8918 is connected with signal source module, signal switching module, after audio-video signal receives chip TSUMV56RU decodings via signal
Output LVDS vision signals and left and right audio signal, left and right audio signal are fed directly to signal pio chip MCS8428Q, LVDS
Vision signal is converted into MIPI signals via signal conversion chip LT8918 and send to signal pio chip MCS8428Q.
MIPI signals and left and right acoustic channels audio signal are decoded coding by the signal pio chip MCS8428Q again, and one
Road is encoded into TS streams by AV mouthfuls of output audio and video, another way, flows signal by SDIO mouthfuls of output TS.
The TS stream signals, which export, gives next stage SOC decoding chips, is converted with completing the unified of audio-video signal.
The signal source module include VGA, the first AV mouthfuls, USB multimedias, HDMI1, HDMI2 and HDMI3.
The signal switching module includes button switching information source and IR remote control switching information sources.
The TS stream signals can realize the lossless conversion of audio-video signal.
Specific embodiment 1：VGA videos connecting line one terminates computer, and the VGA video connecting line other ends are inserted into pinboard, make
It is remotely controlled switching information source with IR or button switching information source switches to VGA information sources, output LVDS is regarded after pio chip TSUMV56R decodings
Frequency signal, LVDS are converted into MIPI signals via signal conversion chip LT8918, send to signal pio chip MCS8428Q, then
Signal pio chip MCS8428Q exports vision signal to TV by AV mouthfuls, while exporting TS and flowing to SDIO interfaces.
Specific embodiment 2：AV signals are produced by the HDMI information sources of set-top box and TS flows signal：It is remotely controlled switching information source using IR
Or after button switching information source is switched to HDMI information sources, signal exports LVDS vision signals after receiving chip TSUMV56R decodings,
LVDS vision signals are converted into MIPI signals via signal conversion chip LT8918, send to signal pio chip MCS8428Q cores
Piece, then signal pio chip MCS8428Q exports vision signal to TV by AV mouthfuls, while exporting TS and flowing to SDIO interfaces.
Compared to the prior art, the advantageous effects of the utility model are：Various video signal and defeated can be accessed
Go out various video signal, selection incoming video signal interface and output video signal interface that can be convenient, flexible, decoding capability
Relatively strong, audio and video lossless can be converted into TS streams.
The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, every according to this
The technical spirit of utility model should be included in this to any trickle amendment, equivalent replacement and improvement made by above example
Within the protection domain of utility model technical solution.
