Embodiment
Technological means and effect of taking for reaching predetermined goal of the invention for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, its embodiment of control method for multi-media playing device, structure, feature and the effect thereof of the adaptability proposing according to the present invention being distributed to power consumption, be described in detail as follows.
Consult Fig. 3, in preferred embodiment of the present invention, multimedia playing apparatus 1 coordinates reception one demodulation receiver 31, a decoder 32, or the signal of a DTV receiver 33, multimedia playing apparatus 1 has a multiplexer 111, a control unit 10, a video processor 11, an audio process 12, a display floater 30, a power amplifier 112, a loud speaker 113 and a power supply unit 20; Wherein, power supply unit 20 supplies each element required electric power, and control unit 10 receives the operational order from for example remote controller, comprise that a selection signal comes sourse instruction 301, an adjustment volume instruction 302, or one adjusts luminance instructions 303; Selecting signal to carry out sourse instruction 301 is to select signal source, and adjusting volume instruction 302 is sound volume setting values of Modulating Power amplifier 112 output volume height, and adjusting luminance instructions 303 is brightness settings of adjusting backlight module 114 output brightness light and shades.
Control unit 10 is controlled multiplexer 111 and is selected one to play from unlike signal source, these signals source comprises from antenna through the signal of demodulation receiver 31, from the anaiog signal of decoder 32, or from the digital signal of DTV receiver 33, the processing suitable through multiplexer 111 separates, then by vision signal supplying video processor 11 and audio signal supply audio frequency processor 12.
11 of video processors are that converting video signal is the size being suitable for playing display floater 30, and increase colour temperature control, sharpness adjustment, reduction noise and the dynamic compensation of vision signal.Audio process 12 is according to pattern of the input decoded audio signal and strengthen a for example ring audio.
Control unit 10 controls according to selecting signal to carry out sourse instruction 301 the output volume size that the multimedia input of multiplexer 111 is originated, foundation is adjusted volume instruction 302 power ratio control amplifiers 112, and controls the backlight module 114 output brightness sizes of display floater 30 according to adjustment luminance instructions 303; Because the consumed power of the backlight module 114 of power amplifier 112 and display floater 30 is the factors that affect overall power consumption maximum, therefore the present invention namely distributes power consumption by self-adjusting mode adaptability.
Consult Fig. 4, and coordinate Fig. 3, control unit 10 receives to be adjusted volume instruction 301 or adjusts after luminance instructions 302 (step 401), add up sound volume setting value and brightness settings (step 402), does and the total value that adds that judges sound volume setting value and brightness settings arrive a predetermined threshold value (step 403)? if arrive predetermined threshold value, if when judgement adjusts upward volume (step 404), automatically reduce brightness settings (step 406); If when judgement adjusts upward brightness (step 405), automatically reduce sound volume setting value (step 407); Because sound volume setting value and adjust brightness settings add total value lower than predetermined threshold value, also just can reduce total consumption power.
Preferably, can design predetermined threshold value according to the power output of power supply unit 20, namely select the power supply unit 20 that power output is less, more how to design predetermined threshold value according to counter the pushing away of gross output.
Media playing apparatus 1 has a high-high brightness set point (as the transverse axis of Fig. 1 indicates 100 place), and consumed power corresponding to high-high brightness set point is 40 watts, and consumed power corresponding to descant amount set point (as the transverse axis of Fig. 2 indicates 100 place) is 25 watts, high-high brightness set point and consumed power proportional (as Fig. 1), sound volume setting value is proportional with consumed power (as Fig. 2) also, the total value that adds of descant amount set point and high-high brightness set point is 65 watts, below predetermined threshold value is designed to 55 watts and principle of the present invention is described for example.
Consult Fig. 5, as an example of sound volume setting value 80 example (with line segment----represent), adjusting upward adjustment brightness settings from 40 to 60 o'clock, brightness is heightened to a certain degree just automatically turning down volume, for example, according to approximately 32 watts of left and right of power consumption of brightness settings 60 correspondences of Fig. 1, but because need are limited in the kind body consumed power of 55 watts, therefore remain 23 watts, be 70 left and right according to the sound volume setting value of 23 watts of the consumed powers of Fig. 2 again, therefore corresponding diagram 5, now will be reduced to sound volume setting value 70 left and right automatically by sound volume setting value 80 originally.
Consult Fig. 6, taking brightness settings 90 as example, adjusting upward adjustment sound volume setting value from 20 to 40 o'clock, volume is heightened to a certain degree just automatically turning down brightness, for example, according to approximately 18 watts of left and right of power consumption of sound volume setting value 40 correspondences of Fig. 2, but because need are limited in the kind body consumed power of 55 watts, therefore remain 37 watts, be 80 left and right according to the brightness settings of 37 watts of the consumed powers of Fig. 1 again, therefore corresponding diagram 6, now will be reduced to brightness settings 80 left and right automatically by brightness settings 90 originally.
In sum, because presetting the total value that adds of adjusting sound volume setting value and adjusting brightness settings, multimedia playing apparatus 1 do not exceed predetermined threshold value, predetermined threshold value is again lower than the total value that adds of descant amount set point and high-high brightness set point, distribute adaptively power consumption according to pre-defined rule, therefore can reduce overall power consumption, also can select the power supply unit 20 that power output is less, therefore really can reach object of the present invention.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solution of the present invention, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
