The accompanying drawing explanation
Accompanying drawing 1 is a kind of full function TV bar structure schematic diagram described in the utility model;
Accompanying drawing 2 is a kind of full function TV rod partial circuit connection diagram described in the utility model.
Embodiment
In order to allow those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of full function TV rod comprises HDMI interface circuit, wireless remote control input circuit, the memory be connected with main control unit respectively, the HDMI interface is connected with the HDMI interface circuit, also comprise row's needle interface, demodulation chip, tuner, demodulation chip connects main control unit by row's needle interface, and tuner and demodulation chip join.Described demodulation chip can be the one or any several combinations in ADTB demodulation chip, DMB-T demodulation chip, DVB-C demodulation chip, DVB-S2 demodulation chip, DVB-T demodulation chip, DVB-T2 demodulation chip, also comprise the ca card interface circuit, the ca card interface circuit connects main control unit by row's needle interface, also comprise the usb interface circuit, the wifi circuit that are connected with main control unit respectively, described ca card interface circuit comprises storage battery conversion circuit, ca card interface.
Described ADTB demodulation chip is the decoding chip that meets Set Top Box ADTB standard, described DMB-T demodulation chip is the decoding chip that meets Set Top Box DMB-T standard, described DVB-C demodulation chip is the decoding chip that meets Set Top Box DVB-C standard, described DVB-T demodulation chip is the decoding chip that meets Set Top Box DVB-T standard, described DVB-T2 demodulation chip is the decoding chip that meets Set Top Box DVB-T2 standard, and described DVB-S2 demodulation chip is the decoding chip that meets Set Top Box DVB-S2 standard.For example the DVB-C demodulation chip should be the chip that can use the demodulation of QAM-64 modulation system the most substantially.These are all that the standard that can look into is arranged, and the prior art scheme of the maturation of recording and narrating in detail, at this, do not make burden.
It can be 90 degree bent angle single rows mothers or 90 degree bent angle double-row mothers that described row's needle interface connects the e end with main control unit.With the demodulation chip link, can be 90 degree bent angle single row pins, can be also 90 degree bent angle double-row pins.
The signal main control unit received from the Internet is directly processed.The demodulation of the signal received from broadcasting and television network is completed by demodulation chip and tuner, and the formal output then flowed with TS is to the master chip on main control unit.The function of tuner has been frequency locking, the frequency-dropping function of high-frequency signal, realizes high-frequency signal is converted to after intermediate-freuqncy signal to the action of being defeated by demodulation chip.Demodulation chip is realized demodulation function in inside after receiving the intermediate-freuqncy signal that tuner is defeated by, and signal is moved from intermediate frequency, is reduced to digital signal, then by row's pin, exports to master chip and is processed.
