| Definition | +5V_USB | TU1_SCL | TU1_SDA | GND | AGC | NC | DETECT | TU_IF- | TU_IF+ |
As shown in Figure 3, it is the circuit connection diagram of female mouthful 103 of the USB3.0 shown in Fig. 1 and video processing module 104 and control module 101.
The pin 1,2,3,5,8,9 that USB3.0 is female mouthful 103 is connected with video processing module 104, and pin 7 is connected with control module 101 by resistance R 1, and pin 7 also passes through resistance R 2 ground connection, pin 4,10,11 ground connection.Pin 6 is vacant.Public mouthful 201 of USB3.0 is corresponding with it.
When the female mouth 103 of USB3.0 is vacant, be not connected for public mouthful 201 with USB3.0.The pin 7(DETECT that USB3.0 is female mouthful 103) by resistance R 2, dragged down as low level, control module 101 is failure to actuate after low level being detected, and the vision signal of display module 102 receiver, video interface module 105 inputs also shows, is referred to as monitor status here.
After USB3.0 is connected for male mouthful 201 with USB3.0 for female mouthful 103, voltage transformation module 203 is by the pin 1(+5V_USB of female mouthful 103 of USB3.0) obtain the voltage of 5V, and be converted into applicable tuner 202 and the required operating voltage of supply module 204, and be tuner 202 and supply module 204 power supplies.
After tuner 202 energising work, high-frequency TV signal is converted into intermediate-freuqncy signal and sends female mouthful 103 of USB3.0 for male mouthful 201 to by USB3.0.
After supply module 204 work, because resistance R 2 resistances are enough large, supply module 204 draws high the pin 7 of the public mouth 201 of USB3.0 into high level.
The pin 7 that control module 101 detects the female mouth 103 of USB3.0 is high level, controls display module 102 and shows described video processing module 104 output image signal contents, that is to say described high-frequency TV signal content, is referred to as tv state.
In tv state use procedure, if USB3.0 is extracted for public mouthful 201, the high level of the pin 7 that USB3.0 is female mouthful 103 disappears, and by resistance R 2, is again dragged down as low level, returns to monitor status.
The relative conventional television of above-mentioned display unit 10, tuner part is external, the female mouth 103 of the USB3.0 of usining is as intermediate-freuqncy signal interface, the state of one of them pin by female mouthful 103 of USB3.0 is controlled and is showed paths, simplify the circuit structure of display unit 10, based on USB3.0, provide processing speed faster, higher bandwidth for clear vision signal again.
In the present embodiment, voltage transformation module 203, tuner 202 and the integrated setting of supply module 204, the pin corresponding with supply module 204 is connected with the pin 7 of the public mouth 201 of USB3.0.
The tuner 202 of corresponding high-frequency conversion circuit 20 obtains work energy for female mouthful 103 by USB3.0, and change the level of a pin of public mouthful 201 of USB3.0, as connection status signal, with realize by female mouthful 103 of USB3.0 and the male mouth 201 of USB3.0 be connected and the switching of display unit 10 show states is carried out in disconnection, make user convenient to operation.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
