Embodiment Construction

[0022] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0023] Please refer to figure 1 , which is a flowchart of a power consumption processing method for dynamic adjustment of DDR frequency in an embodiment of the present invention, the method includes:

[0024] Step S10 , the device 10 plays the video file in response to the video play instruction sent by the user, and at the same time caches the playback state information of the current movie source in the storage unit 12 . Wherein, the playback state information of the current film source may include information such as the resolution of the video file, audio and video synchronization conditions, and the like. The playback information acquisition unit 11 acquires the playback status of the current film source from the storage unit 12 .

Abstract

The invention provides a DDR frequency dynamic regulation power dissipation processing method which comprises the steps that video files are played by responding to video playing instruction sent by a user, the playing state of a current video source is obtained, and the playing state comprises the resolution ratio and the synchronization of audio and video; the playing state of the current video source is analyzed, and whether the video playing state is changed is judged; when the fact that the video playing state is changed is determined, video source information is transmitted; audio and video synchronization information is obtained, and whether audio and video are synchronous is analyzed; and when the fact that audio and video are not synchronous is determined, DDR frequency is adjusted to first frequency, and when the fact that audio and video are synchronous is determined, according to the resolution ratio, DDR frequency is adjusted to second frequency. The invention further provides a related device. The problems such as frame dropping, blocking and asynchrony of audio and video during a video playing process are solved, video fluency is improved, and equipment running time is prolonged.

Description

technical field [0001] The present invention relates to the technical field of DDR frequency processing, in particular to a power consumption processing method and device for dynamically adjusting DDR frequency based on an Android platform video playing scene. Background technique [0002] Playing video is one of the mainstream applications of Android platform devices. The smoothness of video playback and power consumption in this scene directly affect the user experience. Video sources with different resolutions and different code streams have very different requirements for system DDR data bandwidth. For video sources with large resolution and large code streams, higher DDR data bandwidth is required. If the DDR bandwidth is insufficient, video Untimely data processing causes frame drop during video playback, audio and video out of sync, etc., making user experience worse. The video source with small resolution and small code stream has low requirements on the data bandwi...
