Description
Technical field
The utility model relates to field of television, relates to a kind of DTMB digital television specifically.
Background technology
At present domestic have a lot of cities in high definition and the SD digital terrestrial television business opening successively and improve based on DTMB (digital terrestrial signal) standard, and the TV market demand with DTMB digital signal receiving function also will increase day by day.Traditional DTMB digital television comprises: reception antenna, power module, display module and machine core board, and wherein, design has tuner, audio/video decoding module, DTMB demodulation module on the machine core board; Reception antenna is connected with tuner, and tuner connects DTMB demodulation module, power module junctor central layer; Tuner, DTMB demodulation module, display module all connect the audio/video decoding module.
Owing in conventional art, the DTMB demodulation module is integrated on the machine core board, if it is very inconvenient that the user wants to change the DTMB demodulation module, and corresponding with it present situation is: the producer that the DTMB demodulation module is produced in research and development at present is numerous, and all well do not check through market, the bad guarantee of product quality, need to change in case therefore the DTMB demodulation module breaks down, will be pretty troublesome.
The utility model content
Technical problem to be solved in the utility model is: at traditional DTMB digital television is that the DTMB demodulation module is integrated on the machine core board and the problem of the replacing inconvenience that causes, a kind of novel DTMB digital television is proposed, the DTMB demodulation module is separated with machine core board, and satisfy the demand that the user replaces the DTMB module by design interface.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of DTMB digital television comprises reception antenna, power module, display module, DTMB demodulation module and machine core board; Described power module junctor central layer; Design has tuner, audio/video decoding module on the described machine core board; Described reception antenna connects tuner; Described tuner, display module all connect the audio/video decoding module; This television set also comprises interface, and described DTMB demodulation module is connected with the audio/video decoding module by interface, and described tuner is connected with the DTMB demodulation module by interface.
Further, described tuner is the D/A integral high frequency head.
Further, described display module is a LCDs.
The beneficial effects of the utility model are: by the DTMB demodulation module is separated with machine core board, and connect DTMB module and audio/video decoding module by design interface, make the user when the demand of changing the DTMB demodulation module is arranged, can change easily, in the selection of tuner, can select the incorporate tuner of D/A also to satisfy the user analog signal and any demand of switching of digital signal.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
At traditional DTMB digital television is that the DTMB demodulation module is integrated on the machine core board and the problem of the replacing inconvenience that causes, the utility model proposes a kind of novel DTMB digital television, the DTMB demodulation module is separated with machine core board, and satisfy the demand that the user replaces the DTMB module by design interface.
As shown in Figure 1, the DTMB digital television in the utility model comprises reception antenna, power module, display module, DTMB demodulation module, interface and machine core board; Described power module junctor central layer; Design has tuner, audio/video decoding module on the described machine core board; Described reception antenna connects tuner; Described tuner, display module all connect the audio/video decoding module; This television set also comprises interface, and described DTMB demodulation module separates with machine core board, and is connected with audio/video decoding module, tuner by interface.
On concrete enforcement, interface can adopt socket type, is about to the DTMB demodulation module and is plugged on the audio/video decoding module, also can design other interface shape according to user's request; For satisfying the demand of user to analog signal and digital signal switching, tuner can adopt the D/A integral high frequency head, can also can receive analog signal by receiving digital signals; In order to realize the frivolous and low-power consumption of complete machine, display module can be selected LED backlit display for use.
Therefore, by the way the DTMB digital television of design possess that fuselage is frivolous, low in energy consumption, can receive analog signal also can receiving digital signals, can compatible multiple DTMB demodulation module, replace advantages such as convenient.
The operation principle of this digital television is: when tuner receives analog signal, after tuner carries out relevant treatment to analog signal, output simulation CVBS signal decodes for the audio/video decoding module, decoded vision signal is transmitted to display module and shows, audio signal is transmitted to loud speaker and carries out sound-reducing; When tuner receives the DTMB digital radio signal, tuner carries out exporting the middle frequency difference sub-signal after the relevant treatment to the DTMB digital radio signal, and deliver to the DTMB demodulation module, demodulate TS stream through the DTMB demodulation module, delivering to the audio/video decoding module by interface at last decodes, the vision signal that decodes is delivered to display module and is shown, the audio signal that decodes is delivered to loud speaker and carried out sound-reducing.
Interface described in the utility model can be common serial ports or parallel port, perhaps can adopt the form of socket to realize, no longer its concrete structure is given unnecessary details here.
