Multimedia playback device and control method for adaptively distributing power consumption

The invention relates to a multimedia playing device and a control method, in particular to a multimedia playing device and a control method for adaptively distributing power consumption.

In recent years, the consumption of earth resources has been increasing, and people have put more efforts into research on how to save energy. Activities to promote energy reduction have also been launched around the world. At present, most research on multimedia playback devices to reduce power consumption is Backlight brightness control on the display, such as dynamically adjusting brightness based on content or using darker images in special areas, because backlight brightness is the largest source of power consumption.

However, in addition to the backlight module, the existing multimedia playback device includes an AC/DC power supply, a signal control unit, a display, and a speaker, wherein the AC/DC power supply supplies power required for each component.

Referring to FIG. 1, it can be seen from the brightness setting value and the corresponding power consumption of the backlight module of the multimedia playback device that the user can adjust the minimum to maximum brightness, and the power consumption thereof also increases, and when the maximum brightness is reached, the consumption is increased. The power needs at least 40 watts.

Referring to FIG. 2, it can be seen from the volume setting value and the corresponding power consumption that the user can adjust the minimum to the highest volume, and the power consumption also increases, and when the maximum volume is reached, the power consumption needs at least 25 watts.

In general, the power output of an existing AC/DC power supply is designed with the maximum brightness of the display and the maximum power required by the sound, but In actual use, there are very few extreme operating conditions, such as: adjusting to the brightest and adjusting to the maximum sound. In other words, the user still has very little room for adjustment in the brightness/volume range of the operation. Therefore, the excess power capacity design also causes higher cost and unnecessary power consumption. The reaction is in the manufacturing cost, which is the high power used (the power sum of Figure 1 and Figure 2 needs at least The 65 watt AC/DC power supply, in addition to the component cost, also wastes unnecessary output power.

Accordingly, it is an object of the present invention to provide a multimedia playback device and control method, and more particularly to a multimedia playback device and control method for adaptively distributing power consumption.

Therefore, in the multimedia playback device control method for adaptively distributing power consumption, the multimedia playback device has a display panel and a speaker, and the method includes the following steps: (a) receiving an adjustment for adjusting the output volume of the speaker a volume command or an adjustment brightness command for adjusting the brightness of the display panel, the volume adjustment command adjusts a volume setting value representing a volume level, and the adjustment brightness command adjusts a brightness setting value representative of brightness and brightness; (b) adding And determining (c) whether the summed value of the volume setting value and the brightness setting value reaches a predetermined threshold value; if the predetermined threshold value is reached, when the upward adjustment is continued The volume setting value or the adjusting brightness setting value is such that the added value of the adjusted volume setting value and the adjusted brightness setting value does not exceed the predetermined threshold value.

Preferably, the media display device has a maximum volume setting value and a maximum brightness setting value, and the predetermined threshold value is lower than the highest volume setting value and the The sum of the maximum brightness settings. The predetermined threshold is designed according to the output power of the power supply of the multimedia playback device. The brightness setting is lowered when the volume setting is continuously adjusted upward, and is decreased when the adjustment of the brightness setting is continued upward.

The multimedia playing device of the present invention comprises a control unit, a display panel and a speaker. When the control unit receives an adjustment volume command for adjusting the volume setting value of the speaker output volume, or adjusts the brightness of the display panel output brightness and brightness When the brightness adjustment command is set, the control unit determines whether the volume setting value and the total value of the brightness setting value reach a predetermined threshold value, and if the predetermined threshold value is reached, when the volume setting value or the adjustment is continuously adjusted upwards The brightness setting value is such that the added value of the adjusted volume setting value and the adjusted brightness setting value does not exceed the predetermined threshold value.

Preferably, the media display device has a maximum volume setting value for setting the output volume of the speaker and a maximum brightness setting value for setting the output brightness of the display panel, and the predetermined threshold value is lower than the highest volume setting value and the maximum brightness. The sum of the set values. The multimedia playback device further includes a power supply, and the predetermined threshold is designed according to the output power of the power supply. The control unit determines to decrease the brightness setting value when the volume setting value is adjusted upward; or the control unit determines to automatically decrease the volume setting value when the adjusted brightness setting value is adjusted upward.

The effect of the present invention is that the control unit manages the power consumption of the multimedia playback device, adaptively allocates power consumption according to predetermined rules, thereby reducing overall power consumption.

The foregoing and other objects, features, and advantages of the invention are set forth in the <RTIgt;

Referring to FIG. 3, in a preferred embodiment of the present invention, the multimedia playback device 1 is configured to receive a signal from a demodulation receiver 31, a decoder 32, or a digital television receiver 33. The multimedia playback device 1 has a multiplex. The device 111, a control unit 10, a video processor 11, an audio processor 12, a display panel 30, a power amplifier 112, a speaker 113 and a power supply 20; wherein the power supply 20 supplies the components For the required power, the control unit 10 receives an operation command from, for example, a remote controller, including a selection signal source command 301, an adjustment volume command 302, or an adjustment brightness command 303; the selection signal source command 301 is to select a signal source, and adjust the volume command. 302 is a volume setting value for adjusting the output volume of the power amplifier 112. The brightness adjustment command 303 is a brightness setting value for adjusting the brightness of the backlight module 114.

The control unit 10 controls the multiplexer 111 to select one of its playbacks from different sources, including signals from the antenna demodulated receiver 31, analog signals from the decoder 32, or digits from the digital television receiver 33. The signal is separated by appropriate processing by the multiplexer 111, and then the video signal is supplied to the video processor 11 and the audio signal is supplied to the audio processor 12.

The video processor 11 converts the video signal to a size suitable for playing the display panel 30, and increases color temperature control, sharpness adjustment, noise reduction, and motion compensation of the video signal. The audio processor 12 decodes the audio signal in accordance with the input format and enhances, for example, surround sound effects.

The control unit 10 controls the multimedia input source of the multiplexer 111 according to the selection signal source command 301, controls the output volume level of the power amplifier 112 according to the adjustment volume command 302, and controls the output brightness of the backlight module 114 of the display panel 30 according to the adjustment brightness command 303. Since the power consumption of the power amplifier 112 and the backlight module 114 of the display panel 30 is the factor that affects the overall power consumption, the present invention adaptively allocates power consumption by means of automatic adjustment.

Referring to FIG. 4, and in conjunction with FIG. 3, after receiving the adjustment volume command 301 or adjusting the brightness command 302 (step 401), the control unit 10 adds the volume setting value and the brightness setting value (step 402), and determines the volume setting value and the brightness setting. Does the added value of the value reach a predetermined threshold (step 403)? If the predetermined threshold value is reached, if it is determined that the volume is adjusted upward (step 404), the brightness setting value is automatically lowered (step 406); if it is determined that the brightness is adjusted upward (step 405), the volume setting value is automatically lowered (step 407); The sum of the set value and the adjusted brightness set value is lower than the predetermined threshold value, which can reduce the overall power consumption.

Preferably, the predetermined threshold value can be designed according to the output power of the power supply 20, that is, the power supply 20 with a smaller output power is selected, and the predetermined threshold value should be designed according to the total output power.

The media display device 100 has a maximum brightness setting value (as indicated by the horizontal axis of FIG. 1), and the maximum brightness setting value corresponds to a power consumption of 40 watts, and a maximum volume setting value (as indicated by the horizontal axis of FIG. 2) Where) the corresponding power consumption is 25 watts, the maximum brightness setting value is proportional to the power consumption (Figure 1), the volume setting value is also proportional to the power consumption (Figure 2), the highest volume setting value and the maximum brightness setting value. The total value is 65 watts. The following threshold will be reserved. The value is designed to be 55 watts as an example to illustrate the principles of the present invention.

Referring to FIG. 5, taking the volume setting value 80 as an example (indicated by a line segment - - -), when the brightness adjustment value is adjusted upward from 40 to 60, the brightness is turned up to a certain level to automatically adjust the low volume, for example, according to FIG. The power consumption corresponding to the brightness setting value 60 is about 32 watts. However, since the power consumption of the seed body of 55 watts is limited, 23 watts remain, and the volume setting value of 23 watts according to the power consumption of FIG. 2 is about 70, so the corresponding In Fig. 5, the original volume setting value 80 is automatically reduced to about the volume setting value 70.

Referring to FIG. 6 , taking the brightness setting value 90 as an example, when the adjustment volume setting value is adjusted from 20 to 40 upwards, the volume is automatically adjusted to a certain degree, that is, the brightness is automatically turned down, for example, according to the power consumption corresponding to the volume setting value 40 of FIG. 2 . About 18 watts, but because it needs to limit the power consumption of the 55 watt seed, the remaining 37 watts, according to the power consumption of 37 watts according to Figure 1, the brightness setting is about 80, so corresponding to Figure 6, this will be the original The brightness setting value 90 is automatically lowered to about the brightness setting value of about 80.

In summary, since the multimedia playback device 1 presets the set value of the adjusted volume setting value and the adjusted brightness setting value not to exceed the predetermined threshold, the predetermined threshold value is lower than the sum of the highest volume setting value and the maximum brightness setting value. The power consumption is adaptively allocated according to a predetermined rule, so that the overall power consumption can be reduced, and the power supply 20 having a smaller output power can be selected, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are Still belong to this issue The scope of the patent is covered.
