Description

A kind of digital TV integrated machine

Technical field

The present invention relates to digital television techniques, particularly the technology of modularization digital TV integrated machine.

Background technology

Existing digital TV integrated machine adopts the mode of digital television module more, that is: digital TV integrated machine is made of TV main frame and digital television module two parts, adopts unified interface to carry out two information transmission such as control, power supply and signal between the part.At present digital television module has only an interface to be connected with the TV main frame, if want to change module then need to take off when front module and connect new module, and works when not supporting two to reach with upper module, does not possess autgmentability, operates dumb.

Summary of the invention

Technical problem to be solved by this invention in order to overcome the shortcoming that present digital TV integrated machine does not possess autgmentability, provides a kind of digital TV integrated machine and extended method thereof exactly.

The present invention solves its technical problem, the technical scheme that adopts is, a kind of digital TV integrated machine, comprise TV main frame and digital television module, comprise a main interface on the digital television module, digital television module is connected with the TV main frame by main interface, also comprise expansion module, also comprise expansion interface and multiple signals processing module on the described digital television module, the multiple signals processing module is connected with expansion interface, the multiple signals processing module is connected with main interface, and expansion module is connected with digital television module by the expansion interface on the digital television module.

Concrete, described expansion module comprises main interface, expansion interface and multiple signals processing module, the multiple signals processing module is connected with expansion interface, the multiple signals processing module is connected with main interface, and the main interface of expansion module can be connected with the expansion interface of another expansion module or the expansion interface of digital television module.

A kind of extended method of digital TV integrated machine may further comprise the steps:

A. the user connects one to one a digital television module and n-1 expansion module, and the main interface with digital television module is connected with the TV main frame again, realizes the power supply to expansion module of signal and communication and digital television module, and n is greater than in 1 integer;

B. the multiple signals processing module of digital television module has detected the expansion module successful connection one by one, sends expansion module state and information respectively to the TV main frame;

C. after the TV main frame receives all expansion module states and information, analyze and obtain comprising digital television module n module altogether;

D. provide 2 to the userⁿ-a kind of selectable watching mode;

E. select control figure television module and/or corresponding expansion module work according to the user.

The invention has the beneficial effects as follows, can on same TV main frame, connect a digital television module and n-1 expansion module by above-mentioned a kind of digital TV integrated machine and extended method thereof, need not go to change module again, make things convenient for the user, and work when supporting two to reach with upper module is enhanced one's market competitiveness.

Description of drawings

Fig. 1 is the system block diagram of embodiment.

Embodiment

Below in conjunction with drawings and Examples, describe technical scheme of the present invention in detail.

The invention provides a kind of digital TV integrated machine and extended method thereof, at first on digital television module, increase an expansion interface and multiple signals processing module, the multiple signals processing module is connected with expansion interface, the multiple signals processing module is connected with main interface, expansion module connects to form a kind of digital TV integrated machine by expansion interface on the digital television module and digital television module, after if the user connects one to one a digital television module and n-1 expansion module, main interface with digital television module is connected with the TV main frame again, to realize the power supply of signal and communication and digital television module to expansion module, then the multiple signals processing module of digital television module has detected the expansion module successful connection one by one, send expansion module state and information respectively to the TV main frame, after the TV main frame receives all expansion module states and information, analysis obtains comprising digital television module n module altogether, provides 2 to the user thenⁿ-a kind of selectable watching mode, and select control figure television module and/or corresponding expansion module work according to the user.

Embodiment

It is example that this example equals 3 with n, its system block diagram such as Fig. 1.

At first on digital television module, increase an expansion interface and multiple signals processing module, the multiple signals processing module is connected with expansion interface, expansion module one, expansion module two increases an expansion interface and multiple signals processing module respectively, the multiple signals processing module is connected with expansion interface, the multiple signals processing module is connected with main interface, the main interface of expansion module two is connected with the expansion interface of expansion module one, the main interface of expansion module one and the expansion interface of digital television module connect to form a kind of digital TV integrated machine, the TV main frame (comprises digital television module to each module then, expansion module one and expansion module two) power supply, the multiple signals processing module of digital television module at first detects expansion module one successful connection, detect expansion module two successful connections then, then send the state and the information of expansion module one and expansion module two to the TV main frame, after the TV main frame receives the state and information of expansion module one and expansion module two, analysis obtains comprising digital television module 3 modules altogether, provide 7 kinds of selectable watching modes to the user then, be respectively: pattern 1, watch the program of digital television module; Pattern 2 is watched the program of expansion module one; Mode 3 is watched the program of expansion module two; Pattern 4 is watched the program of digital television module and expansion module one; Pattern 5 is watched the program of digital television module and expansion module two; Pattern 6 is watched the program of expansion module one and expansion module two; Mode 7 is watched the program of digital television module, expansion module one and expansion module two.The TV main frame carries out work according to the corresponding module of model selection that the user selects, and wherein, when showing 2 or 2 with the program of upper module, modes such as the picture-in-picture of selecting with the user, mosaic show.

Claims (1)

1. the extended method of a digital TV integrated machine may further comprise the steps:
