Embodiment 1

[0023] figure 1 It shows the implementation process of the method for adjusting the volume provided by the first embodiment of the present invention. The method can be applied in a device for adjusting the volume, wherein the device for adjusting the volume can be built into a digital TV, or can be built into a device capable of performing audio In the audio-video player that plays, the present invention is described with digital TV as an example, as follows in detail:

[0024] In step S101, when a channel change or a TV program content change is detected, the current volume output reference value OutputVol' is calculated according to the volume output value of the current audio after audio decoding.

[0025] In this embodiment, the device for adjusting the volume monitors whether the user switches channels or changes the content of the TV program, and if so, calculates the current volume output reference value OutputVol' according to the volume output value of the current aud...

Embodiment 2

[0043] figure 2 The implementation process of the method for adjusting the volume provided by Embodiment 2 of the present invention is shown, and the details are as follows:

[0044] In step S201, when it is detected that the user adjusts the volume and watches TV programs normally, the actual output volume value of the device is obtained, and a reference reference value OutputVol for volume adjustment is generated and stored according to the actual output volume value. The actual output volume value of the device refers to the amplitude value of the driving signal of the speaker; it may also be the signal value generated by the volume sensor detecting the output volume of the speaker.

[0045] When the device, such as a TV, leaves the factory, the reference reference value OutputVol is set with a default value in the device. When the user adjusts the volume while watching a TV program, the device generates a reference for volume adjustment according to the actual output volu...

Embodiment 3

[0055] image 3 The implementation process of the method for adjusting the volume provided by Embodiment 3 of the present invention is shown, and the details are as follows:

[0056] In step S301, when it is detected that the user is watching a TV program, the actual output volume value of the device is acquired, and a reference reference value OutputVol for volume adjustment is generated and stored according to the actual output volume value.

[0057] In step S302, the current volume output reference value OutputVol' is calculated according to the volume output value of the current audio after audio decoding.

[0058] In step S303, when a channel change or a TV program content change is detected, the current volume output reference value is detected, and it is judged whether the ratio of the current volume output reference value to the preset reference reference value for volume adjustment is within the preset Threshold range, if not within the preset threshold range, execut...

Abstract

The invention is applicable to the field of television technologies, and provides a volume adjusting method and device. The method comprises the following steps of: when the situation that channels are changed or the contents of TV programs are changed is monitored, according to the volume output value of a current audio frequency subjected to audio decoding, calculating a current volume output reference value; according to a preset reference value of volume adjusting and the current volume output reference value, calculating a volume adjusting coefficient; and according to the volume adjusting coefficient, adjusting the volume output value of the current audio frequency subjected to audio decoding into an actual controlled volume output value. According to the invention, when the situation that the channels are changed or the contents of the TV programs are changed is monitored, the volume adjusting device can adjust the volume value automatically through the preset reference value of volume adjusting.

Description

technical field [0001] The invention belongs to the technical field of televisions, and in particular relates to a method and a device for adjusting volume. Background technique [0002] With the mandatory implementation of digital TV, the frequency of using TV set-top boxes in families is getting higher and higher, but when users watch digital TV, they need to re-adjust the volume for each TV channel, especially when the TV program is switched. The volume of the TV fluctuates, which brings a lot of inconvenience to the user. [0003] At present, the method of adjusting the volume of a digital TV is mainly to adjust the main volume and the sub volume. This method can solve the problem of inconsistent volume when the user changes channels during the adjustment process. However, when the same TV channel is played, the content of the TV program changes During the process, for example, when TV series and advertisements are replaced, the sound output by the TV will still fluctua...
