Abstract

Provided is a high-definition video integrated system. Video graphics array (VGA) signals are transmitted to a signal conversion module and transformed into high-definition multimedia interface (HDMI) signals to be outputted through signal conversion, and the HDMI signals are transmitted to an HDMI signal matrix distribution module. A modulation and amplification module converts an input HDMI standard signal into a TTLRGB signal through I2C control, after signal encoding and amplification, the signal is input into a network driver in MI2 mode, and finally output is an RJ45 network signal. A modulation and restoration module modulates and restores the input RJ45 network signal into the HDMI signal and outputs on a displayer. The high-definition video integrated system effectively integrates a plurality of functions, forms the video integrated system which is strong in function, can be used for large places such as subways, stations, schools and large shopping super markets, is at least three years in service life, greatly meets market requirements, and brings large economic benefit to enterprises as well.

Description

A kind of HD video integrated system
Technical field
The utility model relates to the integrated technical field of video, specifically a kind of HD video integrated system.
Background technology
HD video integrated system project be will contain the digital high-definition signal of multichannel input, select wherein one road signal, carry out loss-free long range signals transmission by single netting twine, longer transmission distance can reach 300M.Having simultaneously the signal matrix function namely is a road or the multiple signals that the multiple signals of input selectively outputed to certain appointment.Be mainly used in the high definition transmission of videos such as subway station, full-sized car station, railway station, shopping mall.
News, film, advertisement that the HDTV (High-Definition Television) of each gateway, subway station is being play synchronously, the TV play that many HDTV (High-Definition Television) of the inside, full-sized car station are play synchronously, the shopping mall of several ten thousand square meters is being play the television advertising of a great variety synchronously, but so long distance, multi-faceted transmission, have dropout or unsettled situation? perhaps too far away because of distance, and can't normally watch?
In the face of the demand of these class public places to the HD video transmission, general solution probably is: the signal source of input is linked in the distributor, then tells the high-definition video signal of multiple HDMI interface to television set.But this wherein uses possibly tens distributor steps and distributes the transmission range that just can reach more than the 100M, and this has caused the step decay of signal and the increase of use cost undoubtedly, and has increased the wiring difficulty.Also has in addition kind of a mode, can transmit by wireless mode, but the high-definition video signal of wireless transmission HDMI, present less stable all, poor anti jamming capability, the longest coverage be 50M just also, and the radiation of human body also be can not be ignored, and the HD video system cost of wireless transmission is very expensive.
The utility model content
For the deficiency of above-mentioned technical problem, the utility model purpose provides a kind of HD video integrated system, can guarantee that signal can grow Distance Transmission and undamped, can save again cost and make project installation become simpler.
The technical solution of the utility model is: a kind of HD video integrated system, comprise signal conversion module, HDMI signal matrix distribution module, modulation and amplification module, solution mediation recovery module, it is characterized in that: the VGA signal is delivered to signal conversion module, become the output of HDMI signal by the signal conversion, the HDMI signal is transferred to HDMI signal matrix distribution module; Modulation and amplification module convert thereof into the TTL rgb signal with the HDMI standard signal of input by I2C control, through Signal coding, amplification, are input to network drive in the MI2 mode, are output as at last the RJ45 network signal; Separating the mediation recovery module becomes the demodulation of RJ45 network signal, the reduction of inputting the HDMI signal and outputs on the display.
The utility model has the advantages that: the effective integrated video matrix of this cover video integrated system, distribution, transmission, signal restoring function, the system that is actually several functions effectively integrates, and forms powerful video integrated system.Be used for the large-scale places such as subway, station, school, large-scale shopping supermarket.Product similar above the market not only uses inconvenience, and brings a high price.And we more than at least 3 years in this cover system life-span.Therefore, the success of this cover video system exploitation will be met the need of market greatly, equally also can bring very large economic benefit to enterprise.
Description of drawings
Fig. 1 is electrical block module diagram of the present utility model.
Fig. 2 is modulation and the electrical block module diagram of amplification module in the utility model.
Embodiment
Now by reference to the accompanying drawings, technology contents of the present utility model is described further.
As shown in Figure 1, 2, the VGA signal is delivered to signal conversion module, becomes the output of HDMI signal by the signal conversion, and the HDMI signal is transferred to HDMI signal matrix distribution module; Modulation and amplification module convert thereof into the TTL rgb signal with the HDMI standard signal of input by I2C control, through Signal coding, amplification, are input to network drive in the MI2 mode, are output as at last the RJ45 network signal; Separating the mediation recovery module becomes the demodulation of RJ45 network signal, the reduction of inputting the HDMI signal and outputs on the display.
