Abstract
The invention relates to a method for reducing the power consumption of a set-top box. Options of audio and video output formats are set in a menu interface of the set-top box for a user to select, and a master control chip of the set-top box controls a selected audio and video decoding module to run to decode and output a signal according to the selection of the user, and disables other audio and video decoding modules which are unselected. According to the method, after the user selects a certain audio and video output mode, a central processing unit (CPU) disables the other unused audio and video decoding modules, so that the power consumption of the other unused audio and video decoding modules is reduced, the power consumption of the CPU is reduced to a great extent, the overall power consumption is also reduced, and the service life of the set-top box is prolonged.
Description
Technical field
The present invention relates to the set-top box technique field, specifically be meant a kind of method that reduces set-top box power consumption.
Background technology
The interface of STB is various, high definition STB particularly, and like HDMI, component, CVBS, S terminal, coaxial, optical fiber, analogue audio frequency, network interface, USB etc., corresponding, the audio frequency and video processing module of CPU is also a lot, will cause the power consumption of whole C PU very high like this.But the user can use a certain group of audio-video interface output for general in the use of reality, other audio-video interface then can not used.When using the HDMI interface, other interface such as component, CVBS, S terminal, coaxial, optical fiber, analogue audio frequency etc. can not used like the user.And for example, the user is when using CVBS and analogue audio frequency, and other interface such as HDMI, component, S terminal, coaxial, optical fiber etc. then can not used.But the decoder module that this part function do not used and interface are corresponding is still being worked, and power consumption is also wasted in consumption in vain.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that reduces set-top box power consumption.
For solving the problems of the technologies described above, the present invention adopts following technical scheme to realize:
A kind of method that reduces set-top box power consumption is characterized in that, said method comprises:
(1) options of audio frequency and video output format is set in the set-top box menu interface;
(2) user at first selects video output mode through above-mentioned options:
(a) select the output of HDMI form like the user, then component, composite video signal CVBS or S terminal decoder module are closed in STB main control chip control operation HDMI decoder module decoding output; Simultaneously, main control chip is closed the analogue audio frequency decoder module, operation digital audio decoding module decoding output;
(b) select component format output like the user, HDMI, composite video signal CVBS or S terminal decoder module are closed in then STB operation component decoder module decoded video output; And the audio frequency output mode of further judges selection;
(c) select composite video signal CVBS or the output of S terminal like the user, then component, HDMI decoder module are closed in STB operation composite video signal CVBS or S terminal decoder module decoding output; And the audio frequency output mode of further judges selection;
(d) if the user selects the analogue audio frequency output mode, then main control chip operation analogue audio frequency decoder module is closed the digital audio decoding module, the output analogue audio frequency;
(e) if user-selected number word audio frequency output mode, then main control chip operation digital audio decoding module is closed the analogue audio frequency decoder module, outputting digital audio.
Compared with prior art; Beneficial effect of the present invention is: after selecting a certain audio frequency and video output mode according to the user in the said method; CPU closes other untapped audio/video decoding module, thereby practices thrift the power consumption that other does not use the audio frequency and video module, has both reduced the power consumption of CPU to a great extent; Also reduce Overall Power Consumption, improved the useful life of STB.
Description of drawings
Fig. 1 is the method for the invention schematic flow sheet.
Embodiment
Below will combine accompanying drawing and embodiment that the present invention is explained in further detail for the ease of it will be appreciated by those skilled in the art that.
Like Fig. 1; The method of disclosed reduction set-top box power consumption; Need in the set-top box menu interface, to be provided with in advance the options of audio frequency and video output format, supply the user to select video output mode, follow-up audio frequency and video output mode according to selection judges whether needs selection audio frequency output mode again.
The video output mode that provides in the STB has multiple, generally comprises but is not limited to HDMI interface output mode, composite video signal CVBS or S terminal output mode, component output mode; The audio frequency output mode has only two kinds to be DAB output mode and analogue audio frequency output mode.Wherein the HDMI interface is meant that (English: High Definition Multimedia Interface, HDMI), it is a kind of digitized video/COBBAIF to HDMI, is the tailored version digital interface that is fit to the image transmission.S terminal (S-Video) is to use one of the most general video interface, is the special-purpose output interface of a kind of vision signal, and common S terminal is one 5 core interface, two-way transmission of video luminance signal wherein, and two-way transmission carrier chrominance signal, the one tunnel is public shielding earth.The component vide interface is also referred to as the color difference components interface; Promptly separately send the blueness poor (b) in colourity (C) signal, red poor (r); 3 holding wires of general using transmit light tone and two-way color difference signal respectively; Its resolution can reach more than 720 lines, and the effect of component output will be higher than the S terminal, and component output supports progressive signal output S terminal then not support.
Select the output of HDMI form like the user, then component, composite video signal CVBS or S terminal decoder module are closed in STB main control chip control operation HDMI decoder module decoding output; Simultaneously, main control chip is closed the analogue audio frequency decoder module, operation digital audio decoding module decoding output.
Select component format output like the user, HDMI, composite video signal CVBS or S terminal decoder module are closed in then STB operation component decoder module decoded video output; And the audio frequency output mode of further judges selection.If the user selects the analogue audio frequency output mode, then main control chip operation analogue audio frequency decoder module is closed the digital audio decoding module, the output analogue audio frequency; At this moment, if user-selected number word audio frequency output mode, then main control chip operation digital audio decoding module is closed the analogue audio frequency decoder module, outputting digital audio.
Select composite video signal CVBS or the output of S terminal like the user, then component, HDMI decoder module are closed in STB operation composite video signal CVBS or S terminal decoder module decoding output; And the audio frequency output mode of further judges selection; At this moment, if user-selected number word audio frequency output mode, then main control chip operation digital audio decoding module is closed the analogue audio frequency decoder module, outputting digital audio.
The not concrete mode of closing each decoder module of introducing among the present invention, it can adopt those skilled in the art's customary means, for example never calls the decoding subprogram that is not used output interface, closes the register of this decoded portion etc., repeats no more at this.
The preferred version that the foregoing description is realized for the present invention; And indefiniteness is exhaustive, and the present invention can also have other variations under same idea, need to prove; Conceive under the prerequisite not breaking away from the present invention, any conspicuous replacement and minor variations are all within protection scope of the present invention.
