Embodiment 1

[0029] The first embodiment is to illustrate the method for controlling audio and video playback of the present invention from the perspective of the mobile phone system, such as figure 1 As shown, a method for controlling audio and video playback is provided in Embodiment 1, including the following steps:

[0030] S11 detects the state of the Hall sensor through the Hall sensor drive module; the state of the Hall sensor corresponds to the state of the rotating camera;

[0031] S12 judges whether the state of the Hall sensor changes, if so, then enters S13; if not, then returns to S11;

[0032] The hall sensor driving module described in S13 triggers and generates a status change broadcast;

[0033] S14 After receiving the status change broadcast, the media control service detects the playback status of the current audio and video software, and controls the playback status according to the status change broadcast.

[0034] In existing mobile phones, the rotating camera can b...

Embodiment 2

[0051] The second embodiment describes the method for controlling audio and video playback of the present invention from the perspective of audio and video software, such as image 3 As shown, a method for controlling audio and video playback is provided in Embodiment 2, including the following steps:

[0052] S21 audio and video software monitors the status change broadcast triggered by the Hall sensor drive module;

[0053] S22 audio and video software obtains the current playback state after receiving the state change broadcast;

[0054] S23 The audio and video software controls the playback state according to the state change broadcast.

[0055] The rotating camera on the mobile phone can be used as both the rear camera and the front camera. The mobile phone detects the state of the rotating camera through the Hall sensor, that is, the state of the Hall sensor corresponds to the state of the rotating camera. For example, in the rotating camera The status of the Hall sens...

Abstract

The invention discloses a method and system for controlling audio and video playing. The method comprises the following steps that: the state of a Hall sensor is detected by a Hall sensor driving module; the state of the Hall sensor is corresponding to the state of a rotary camera; when the state of the Hall sensor is changed, and the Hall sensor driving module is triggered and generates state change broadcast; and after receiving the state change broadcast, media control services detect the playing state of current audio and video software, and controls the playing state according to the state change broadcast. According to the method and system of the invention, the function of the rotary camera in a mobile phone is fully utilized, and audio and video playing can be controlled through the state of the Hall sensor corresponding to the state of the rotary camera in the mobile phone, and therefore, a user can realize control on audio and video playing through operating the rotary camera. With the method and system of the invention adopted, the control on the audio and video playing is more flexible, and the utilization ratio of the Hall sensor can be improved. The method and system have a bright application prospect.

Description

【Technical field】 [0001] The invention relates to the technical field of intelligent electronic equipment, in particular to a method and system for controlling audio and video playback. 【Background technique】 [0002] When playing music with a mobile phone, the user's mobile phone is often placed in the pocket. When playing music, you will take off the earphones when you meet someone you know to say hello or talk about something. At this time, if you don’t want to miss the current piece of music, you usually take out your phone and click the music to pause. After you have said hello or finished talking Then click to continue playing music, this mode of operation brings great inconvenience to the user. [0003] Mobile phones with rotating cameras are already on the market. Users can manually adjust the front or rear of the camera to take pictures. Its powerful camera functions and interesting designs have been widely praised. The state of the rotating camera corresponds to ...
