Example Embodiment

[0045] Example one

[0046] The embodiment of the present invention implements a method for switching the play mode, such as figure 1 As shown, the method includes the following steps:

[0047] Step 101: When the terminal is playing video, it detects an event that triggers the switching of the play mode;

[0048] Specifically, the terminal performs video playback as video and audio playback. Generally speaking, when the terminal performs video playback, it decodes the video and audio separately, and then plays it according to the timestamp; during video playback, The terminal starts the detection of the event that triggers the switching of the play mode, and the event is a set of events that trigger the switch of the play mode:

[0049] For terminals such as mobile phones, PADs, PCs, etc., the event may be the occurrence of a gesture used to trigger the switching of the playback mode, and / or the occurrence of a human eye change used to trigger the switching of the playback mode, and / o...

Example Embodiment

[0058] Example two

[0059] The second embodiment of the present invention implements another method for switching the play mode, such as figure 2 As shown, the method includes the following steps:

[0060] Step 201: When the terminal starts video playback, it selects to enter the automatic switching playback mode or the normal playback mode.

[0061] Specifically, when the terminal starts video playback, a selection dialog box is provided on the interface, and the user can choose whether to automatically switch the playback mode or the normal playback mode. When the normal playback mode is selected, the video is played normally.

[0062] When the user chooses to automatically switch the playback mode, the terminal can switch the playback mode in real time: from video playback mode to audio playback mode, or from audio playback mode to video playback mode.

[0063] Among them, the video play mode is to process both audio data and video data, that is, a conventional video play mode; the...

Example Embodiment

[0092] Example three

[0093] The third embodiment of the present invention provides a device for switching play modes, such as image 3 As shown, the device includes: a detection module 301, a switching module 302, and a data processing module 303; among them,

[0094] The detection module 301 is used to detect the event that triggers the switching of the play mode;

[0095] The switching module 302 is configured to switch the video playback mode when an event that triggers the switching of the playback mode is detected;

[0096] The data processing module 303 is used to process video data and audio data.

[0097] Specifically, the event that triggers the switching of the play mode is the event described in the first embodiment, and the detection method of the detection module 301 can be sound control detection, or infrared detection, or mechanical connection detection, or electrical Connection detection and so on. Of course, in the embodiment of the present invention, it includes bu...

Abstract

Disclosed is a method for switching playback mode, the method comprising: when a terminal is playing a video and detects the occurrence of an event triggering switching of playback mode, switching to audio playback mode and stopping processing of video data. Also disclosed are a device and terminal for switching playback mode. The solution of the present invention can achieve freedom of real-time switching of video playback mode on a terminal, saving power and increasing standby time.

Description

technical field [0001] The present invention relates to the field of multimedia, in particular to a method, device and terminal for switching playing modes. Background technique [0002] As we all know, when the terminal is playing the video, it decodes the video and the audio separately, and then plays it according to the time stamp. For general video formats, most of them can be decoded by hardware, and for some special video encoding formats, software decoding may be used. Whether it is high-speed hardware decoding or relatively low-speed software decoding, a certain amount of energy consumption will be generated. [0003] This playback mode does not apply to the following situations: [0004] Mobile terminal: The characteristic of mobile terminal is that the battery energy capacity is small, and users have high requirements for standby time and high requirements for the running time of all applications; [0005] No one watching mode: This situation is the same no matt...
