Wherein, H1 signal, H2 signal, H3 signal can be inputted or single input or any two inputs simultaneously simultaneously.Described H5 signal, H7 signal, H7_1 signal can be inputted or arbitrary input simultaneously.The course of work is as follows:
User inserts smart card in module TV, and DVD, the HDMI data wire of the equipment such as Set Top Box has been received on the Hdmi port3 terminal 202 of the HDMI interface of smart card (Hdmi port1 terminal 102, Hdmi port2 terminal 103) and/or screen end card.Based on smart card operation Android system, can better carry out picture processing, and realize some other functions, as SOC chip is pushed to mobile phone terminal by miracast by the picture of televising.
1) in the time of the HDMI input that uses smart card:
H1 signal and/or H2 signal input SOC chip 110 carry out signal processing synthetic osd interface.SOC chip 110 is exported H7 signal and is transferred to the 2nd HDMI diverter switch 220 by connector, simultaneously, SOC chip 110 is also exported the first switching signal control the 2nd HDMI diverter switch 220 and is exported H6 signal to driving control chip 230, drive control chip 230 to H6 signal carry out data decompression format conversion, packing generates VB1 signal and exports to drive display screen.
2) in the time of the HDMI input that uses screen end plate:
H3 signal inputs to HDMI diverter switch 210, the one HDMI diverter switches 210 and exports H4 signal and be transferred to SOC chip 110 by connector, and SOC chip 110 carries out signal processing synthetic osd interface to H4 signal.SOC chip 110 is exported H7_1 signal and is transferred to the 2nd HDMI diverter switch 220 by connector, simultaneously, SOC chip 110 is also exported the first switching signal control the 2nd HDMI diverter switch 220 and is exported H6_1 signal to driving control chip 230, drive control chip 230 to H6_1 signal carry out data decompression format conversion, packing generates VB1_1 signal and exports to drive display screen.
If user does not buy smart card, or smart card is not inserted on television set, independent screen end plate also can be used as a monitor and uses, and now by DVD, the HDMI holding wire of the equipment such as Set Top Box is directly connected on the HDMI interface (Hdmi port3 terminal 202) of screen end plate.Now TV is equivalent to a simple display, although can not realize the intelligent function of smart card, still can meet common television-viewing demand.
3) only have in the situation of screen end plate:
H3 signal inputs to a HDMI diverter switch 210, owing to now controlling without SOC chip 110, the one HDMI diverter switch 210 is exported H5 signal to the 2nd HDMI diverter switch 220, the 2nd HDMI diverter switch 220 is exported H6_2 signal to driving control chip 230, drive control chip 230 to H6_2 signal carry out data decompression format conversion, packing generates VB1_2 signal and exports to drive display screen.
In sum, the module TV of a kind of HDMI of processing signal that the utility model provides, by increasing HDMI diverter switch at screen end plate, the HDMI signal of screen end plate input can be transferred to SOC chip and carry out signal processing synthetic osd interface, loading after transmission process afterwards osd interface HDMI signal give drive control chip carry out data decompression and format conversion, the VB1 signal that final output display screen can be identified drives display screen, makes to demonstrate on display screen UI interface; Solve existing module TV can not generate corresponding UI interface problem from the HDMI signal of screen end plate input, promote the overall performance of television set, can also make the HDMI signal that shields end plate input also can realize monitor function and miracast function, promote the signal switching capability of screen end plate.
Be understandable that; for those of ordinary skills; can be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, and all these changes or replacement all should belong to the protection range of the appended claim of the utility model.
