Upper viewing digital television program.Tuner is the important component of television set, and tuner is that television set is used for receiving high frequency letter
Number and demodulate a kind of device of video information.Set top box for satellite receiver needs to provide for the tuner of television set when receiving signal
Voltage drives tuner demodulated signal using the voltage.If receiving the signal of horizontal polarization mode, the set-top box is needed to be
The voltage that tuner provides 18v or so needs set-top box to be provided for tuner if to receive the signal of vertical polarization mode
The voltage of 13v or so.Set-top box in the prior art does not also seek unity of standard to supplying power for tuner voltage, vertical polarization mode
The general power supply voltage range of signal is 12.8v-13.9v, and the power supply voltage range of the signal of horizontal polarization mode is 17.8v-
18.9v.The required optimum voltage of tuner of different vendor's production is different, all there are one best range of voltage values,
If set-top box cannot provide the voltage in this optimum range, tuner signal reception will be made to weaken, and increase machine
Top box power consumption.It would therefore be highly desirable to develop a kind of detection side of the optimum reception voltage range of the tuner of adaptation different vendor production
Method.
Invention content

Minimum voltage in range is as starting test voltage value.Step 2) further includes, after set-top box sets test voltage, machine top
Box can be with the voltage value come lock signal, the intensity and quality of tracer signal later.Step 3) further includes that test voltage therein increases
Long step-length is 0.1v, if the test voltage of setting has had exceeded the voltage tester scope limited in step 1), terminates height
Frequency head voltage tester.Step 4) further includes checking step 2) in record signal strength and quality, select one group or it is multigroup most
Good signal index, and find tuner voltage value corresponding with the signal index.Wherein best signal index refers to letter
Number intensity highest, it is best in quality.
The step 5) includes showing tuner optimum voltage range used in user.The set-top box is satellite receiver
Top box, the tuner are television tuners.
Compared with the existing technology, the present invention has the following advantages：
Method using the present invention, set-top box can intelligently, can the arbitrary producer's tuner of indiscriminate detection most
Good receiving voltage range, to provide the voltage in optimum range for tuner so that tuner enters best reception state, together
When save set-top box power consumption.
Description of the drawings
Fig. 1 is the flow chart of the embodiment of the present invention.
Specific implementation mode
The technical solution further illustrated the present invention in conjunction with specific embodiment.
A kind of method of automatic detection tuner voltage includes, as shown in Figure 1, it includes the following steps：
Step 1)：According to the different types of polarizations mode that set-top box receives, tuner voltage tester scope is selected,
And minimum test voltage value is set；
Step 2)：Start to test, records current signal strength and quality；
Step 3) judges whether current voltage exceeds the voltage range of this kind of polarizations mode, if believed without departing from this kind
The voltage range of number polarization mode, then increase 0.1v on current voltage, be then back to step 2), if exceeding this kind of pickup electrode
4) voltage range of change mode then enters step；
Step 4)：The voltage value of corresponding tuner when judging signal preferably, and store the voltage value；
