DVI is to be based on TMDS, changes minimum differential signalling technique to transmit data signal, TMDS calculates with advanced coding 8bit data (every roadbed chrominance signal in R, G, B) are encoded to IObit data by minimum transition and (believed comprising row field synchronization by method Breath, clock information, data DE, error correction etc.), after DC is balanced, using differential signal transmission data, it and LVDS, TTL are compared There is preferable Electro Magnetic Compatibility, the private cable of low cost can be used to realize long range, the digital data transmission of high quality. The connection transmission structure of TMDS technologies is as shown in Figure 1.Digital visual interface (DVI) is a kind of interface standard of international openness, It is widely used in the equipment such as PC, DVD, high definition television (HDTV), high-resolution projecting apparatus.DVI information sources common at present regard Frequency data distributor is unable to the limited equipment in adaptation data signal input port, and efficiency of transmission is low, it is impossible to meets the need used Will.

Utility model content

The purpose of this utility model is to provide a kind of DVI information sources video data distributor, to solve above-mentioned background technology The problem of middle proposition.

To achieve the above object, the utility model provides following technical scheme：A kind of DVI information sources video data distributor, Including DVI high definition modular converters, the input of the DVI high definitions modular converter is connected with signal source receiving port, and the information source connects Also be equipped with cable equalizer between receiving end mouth and DVI high definition modular converters, the cable equalizer and signal source receiving port it Between be equipped with input nonlinearities suppression module and input lightning-protection module, between cable equalizer and DVI the high definition modular converter Also it is equipped with output AF panel module and output end lightning-protection module, the outside of the DVI high definitions modular converter is also associated with controlling Button processed, the data output end of the DVI high definitions modular converter are connected with reception video storage modules, the DVI high definitions conversion The control terminal of module is also connected with the video selection control button of outside, and the DVI high definitions modular converter is with receiving video storage Interconnecting modules are also equiped between module, the interconnecting modules include protocol conversion module, the data buffering module being sequentially connected And switch array module.

Preferably, the data output end of the VI high definitions modular converter is also associated with high-clear display.

Preferably, the inside for receiving video storage modules is provided with the detachable RAM card for being inserted with RAM card Neck or Portable movable hard disk.

Preferably, the data storage end of the RAM card neck or Portable movable hard disk is also associated with control terminal Wireless data transmission module.

Compared with prior art, the beneficial effects of the utility model are：The DVI information source video datas distributor uses DVI High definition modular converter support DVI-D signals, have broadband, high speed, high accuracy, High Output Current, low noise, low-power consumption it is good Performance, the data protocol modular converter in the DVI information source video data distributors can make the data protocol of interconnection equipment simultaneous mutually Hold, data buffering module can be such that the data of multiple equipment are exported on a data signal port, be inputted with adaptation data signal The limited equipment of mouth, can extend the distance between DVI equipment and computer using cable equalizer structure, improve the transmission of device Efficiency.
