For solving the problem, the technical scheme that the utility model adopts is as follows:
A kind of multi-path high-definition digital audio-video signal mixture control, comprises power circuit and control circuit,
Also comprise multiple signal compound circuit and multiple signal selecting switch circuit;
Each signal compound circuit all has a HDMI signal input part and multiple signal output part;
Each signal selecting switch circuit all has multiple signal input part and a HDMI signal output part;
The signal output part of each signal compound circuit is connected with a signal input part of each signal selecting switch circuit respectively;
Described signal compound circuit is used for the HDMI signal of reception to deliver to each signal selecting switch circuit;
The HDMI signal that described control circuit selects one of them to receive for control signal selected on-off circuit exports.
Preferably, described control circuit is connected with RS232 serial ports, and this RS232 serial ports is used for reception control signal, and the HDMI signal that control circuit selects one of them to receive according to this control signal control signal selected on-off circuit exports.
Preferably, described control circuit is connected with function button, and this function button is used for input control signal, and the HDMI signal that control circuit selects one of them to receive according to this control signal control signal selected on-off circuit exports.
Preferably, described function button is the button with auto-lock function.
Preferably, described control circuit is connected with infrared remote receiver, and this infrared remote receiver is used for reception control signal, and the HDMI signal that control circuit selects one of them to receive according to this control signal control signal selected on-off circuit exports.
Preferably, described control circuit is connected with infrared prolongation transmission line, and this infrared remote receiver is located at the end of infrared prolongation transmission line.
Preferably, described signal compound circuit is identical with the quantity of signal selecting switch circuit.
Compared to existing technology, the beneficial effects of the utility model are:
By signal compound circuit, HDMI signal can be sent to multiple signal selecting switch circuit to export, thus solve the problem of HDMI signal difficulty distribution; Meanwhile, the HDMI signal that control circuit selects one of them to receive for control signal selected on-off circuit exports, and also exempts the step selecting signal source to need rewiring, thus solves the problem of HDMI signal switching difficulty.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the connection diagram of the utility model control circuit and miscellaneous part.
Reference numeral is as follows:
1, power circuit; 2, control circuit; 3, signal compound circuit; 4, signal selecting switch circuit.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, multi-path high-definition digital audio-video signal mixture control described in the utility model comprises power circuit 1, control circuit 2,4 signal compound circuit 3 and 4 signal selecting switch circuit 4; Each signal compound circuit 3 all has a HDMI signal input part and 4 signal output parts; Each signal selecting switch circuit 4 all has 4 signal input parts and a HDMI signal output part; The signal output part of each signal compound circuit 3 is connected with a signal input part of each signal selecting switch circuit 4 respectively; Described signal compound circuit 3 is for delivering to each signal selecting switch circuit 4 by the HDMI signal of reception; The HDMI signal that described control circuit 2 selects one of them to receive for control signal selected on-off circuit 4 exports.
Wherein, described control circuit 2 is connected with RS232 serial ports, and this RS232 serial ports is used for reception control signal, and control circuit 2 carrys out according to this control signal the HDMI signal that control signal selected on-off circuit 4 selects one of them to receive and exports.
