Problems solved by technology

[0005] In the existing music sleep mode, the volume of the music played during the user preset time period remains constant. When the user wants to fall asleep with music, the constant volume is not suitable for the user to fall asleep, and if the user preset If the setting time is longer, then the user will continue to play music at the original volume after falling asleep, which will not only consume a lot of power, but also easily cause damage to the user's hearing, and the user experience is not good.

Embodiment 1

[0027] An embodiment of the present invention provides a control method for audio and video output, which can automatically reduce the current volume gradually and gradually according to the first time interval and the first volume adjustment unit, and automatically close when the final volume is less than or equal to the off value Audio and video output, wherein the audio and video output includes audio output and video output. see figure 1 , the method flow includes:

[0028] 101: start timing when there is audio and video output;

[0029] 102: When the timing reaches the first time interval, reduce the volume of the audio and video output according to the first volume adjustment unit;

[0030] 103: Determine whether the volume of audio and video output is less than or equal to the closing value, if less than or equal to the closing value, then execute 104, if greater than the closing value, then return to execute 101, and start timing again;

[0031] 104: When the volume...

Embodiment 2

[0034] The embodiment of the present invention provides a control method for audio and video output. The method can pre-set the volume to be lowered every time according to the user's needs. The current volume will be gradually reduced according to the time period. When the final volume is less than or equal to the off value, the audio and video output will be automatically turned off, so as to reduce unnecessary power consumption and protect the user's hearing. Wherein, the audio and video output includes audio output and video output, that is to say, the method provided by the embodiment of the present invention can be applied to both the audio output scene and the video output scene, and the embodiment of the present invention uses "audio and video output" Summarize and describe together. For ease of description, the embodiment of the present invention takes the audio and video output control device as a mobile phone as an example, and describes the method provided by the e...

Embodiment 3

[0055] An embodiment of the present invention provides an audio and video output control device capable of implementing the method steps in Embodiment 1 and Embodiment 2. The device may be an electronic device such as a mobile phone, a PDA, a notebook computer, a tablet computer, an MP3 / MP4 player, or the like. see image 3 , the device consists of:

[0056] Timing module 301, for when there is audio and video output, start timing;

[0057] The volume adjustment module 302 is used for reducing the volume of the audio and video output according to the first volume adjustment unit when the timing module 301 timing reaches the first time interval;

[0058] The first judging module 303 is used to judge whether the volume of the audio and video output adjusted by the volume adjusting module 302 is less than or equal to the closing value;

[0059] The stop module 304 is configured to turn off the audio and video output when the first judging module 303 judges that the volume of t...

Abstract

The invention discloses an audio / video output control method and equipment, belonging to the field of signal processing. The method comprises the following steps of: when audio / video output exists, beginning to timing; when the timing reaches a first time interval, reducing the volume of the audio / video output according to a first volume adjustment unit; and judging whether the volume of the audio / video output is less than or equal to a closed value, and closing the audio / video output if the volume of the audio / video output is less than or equal to the closed value. The equipment comprises a timing module, a volume adjusting module, a first judging module and a stop module. According to the invention, when the timing reaches the first time interval, the volume of the audio / video output is automatically reduced according to the first volume adjustment unit, and when the final volume is less than or equal to the closed value, the audio / video output is automatically closed, therefore the effects of reducing unnecessary electric quantity consumption, protecting hearing of users and improving user experience are achieved.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to a method and device for controlling audio and video output. Background technique [0002] At present, playing music has become a common function of mobile phones, and people like to use mobile phones to listen to music anytime and anywhere to relax themselves. When the user uses the mobile phone to listen to music in some special scenarios, such as before going to bed, if the user forgets or cannot turn off the player, for example, the user falls asleep, the player will continue to play music, and the mobile phone cannot enter the standby state. It will consume the remaining power of the mobile phone, and listening to music for a long time is likely to cause damage to the user's hearing, and the user experience is not good. [0003] Therefore, in order to save the power of the mobile phone and improve the user experience, many existing mobile phones have a music sleep mode, that...
