For example the selection signal of this moment is to open the HDMI function, and described control unit 32 is opened a HDMI gear in (or startup) interior several differential images gears 391 of this differential signal selected cell 39 immediately according to the 3rd control command of selecting signal to produce, the 3rd differential signal (HDMI signal) on the second connecting interface 381 that be connected with the HDMI gear this moment, just can be passed through by this HDMI gear.Wherein said several differential images gear 391 is with difference instruction gear 392 as be all a switch member, for example difference instruction gear 392 receives the first differential signal and switches unlatching (or also can claim conducting), and described each differential images gear 391 a wherein differential images gear 391 receives the 3rd control command and switches unlatching (or also can claim conducting).
Moreover, aforementioned many signal receiving modules 5 more comprise differential signal allocation units 54, these differential signal allocation units 54 1 ends connect the other end of this grid line 61, its other end solves unit 51 with this difference respectively and corresponding another electronic equipment 7 is connected, and these differential signal allocation units 54 connect corresponding electronic equipment 7 by several short-terms 64 (as HDMI, DVI, DISPLAY PORT form cable).
so these differential signal allocation units 54 successively receive the first differential signal and the 3rd differential signal, in other words, described exactly differential signal allocation units 54 are first differential signals that first this differential signal selected cell 39 transmitted by grid line 61, distribute to this difference and solve unit 51, making difference solve 51 pairs of unit receives the first differential signal and does the solution difference processing, send again this signal distribution unit 53 to after solving the first control command, allow signal distribution unit 53 that this first control command is dispensed on its interior RS232 connecting interface 532 and passes through, carry out corresponding running (as the HDMI pattern) to send this electronic equipment 7 (as the LCD screen) to, and then the 3rd differential signal (as the HDMI signal) that can will receive of differential signal allocation units 54 is assigned to directly that corresponding electronic equipment 7 (as LCD display) is upper carries out relative running (as playing the HDMI signal).
Below for an embodiment, explain:
see also Fig. 4,5 and show, in the electronic equipment 7 in an embodiment, with 1 projector and 1 LCD display, explain, when the user selects to press the HDMI button from aforementioned selection boundary element 31, this control unit 32 can produce corresponding previous burned the first control command (being the HDMI instruction in the RS232 instruction) according to the selection signal of selecting boundary element 31 to transmit, send signal selected cell 33 to, simultaneously control unit 32 also can transmit display and controls display interface unit 35 and light the HDMI cresset on it, continue aforementioned signal selected cell 33 just switch in it RS232 gear 331 for the first control commands transmission by to this slip subdivision 34, 34 of this slip subdivisions are converted to the first differential signal to receiving described the first control command, send this differential signal selected cell 39 to, make differential signal selected cell 39 in it just switched differential instruction gear 392 pass through for the first differential signal transmission, and by grid line 61, be sent on these many signal receiving modules 5, after making the differential signal allocation units 54 of described many signal receiving modules 5 will receive the first differential signal to distribute to described difference and solve unit 51, difference solves unit 51 and just to receiving the first differential signal, does the solution difference processing, send again this signal distribution unit 53 to after solving the first control command, and then via signal distribution unit 53, the first control command is dispensed on RS232 connecting interface 532 in it and passes through, and be sent on LCD display, make LCD display just according to the first control command, switch to the HDMI pattern,
then aforementioned control unit 32 can transmit according to selecting signal to produce the 3rd corresponding control command to differential signal selected cell 39 again, after removing to select to open the HDMI gear (namely switching to the HDMI gear) in the interior several differential images gears 391 of differential signal selected cell 39, the 3rd differential signal (HDMI signal) on the second connecting interface 381 that this HDMI gear connects just passes through thus, and by grid line 61, send many signal receiving modules 5 to, the 3rd differential signal (as the HDMI signal) that the differential signal allocation units 54 of described many signal receiving modules 5 can will be received directly is assigned on corresponding LCD display carries out relative running (as playing the HDMI signal), therefore, make and effectively reach the saving cost, effect simple and easy and the saving human cost is installed.
The above, the utility model compared to existing have advantages of following:
1. has the wire rod of minimizing use amount, so as to reaching cost-effective effect;
2. have and do not need the special maintenance personnel to safeguard voluntarily and to install, therefore effectively can reach the effect of simple and easy plug and play being installed and saving human cost;
3. have the signal of reaching and do not produce delay phenomenon and nonsynchronous effect.
Only the above, be only better feasible embodiment of the present utility model, and the variation that such as utilizes the above-mentioned method of the utility model, shape, structure, device to do, all should be contained in interest field of the present utility model.
