no. 1 Embodiment

[0058] In the first specific embodiment of the present invention, the video file playback processing method is as follows figure 1 shown, including:

[0059] Step 11, obtaining and saving the first power consumption rate (ie, the power consumption per unit time) corresponding to the wireless display mobile device playing video files of different resolutions;

[0060] Step 12, obtaining the current power of the wireless display mobile device and the first resolution and playback duration of the original to-be-played video file;

[0061] Step 13, according to the first power consumption rate corresponding to the video files of different resolutions played by the wireless display mobile device, the first resolution of the original to-be-played video file and the playback duration, calculate the playback resolution of the wireless display mobile device as: the first power consumed by the original to-be-played video file of the first resolution;

[0062] Step 14, determine whethe...

no. 2 Embodiment

[0106] In order to reduce the power consumption when the wireless display mobile device plays video files, the second specific embodiment of the present invention provides a wireless display mobile device, the highest resolution supported for playing video files is the first resolution, such as Figure 4 shown, including:

[0107] a receiving module for receiving display data for displaying the video file to be played through a wireless interface;

[0108] a decoding module for decoding the received display data;

[0109] a video memory module, used for saving the pixel information of the to-be-played video file obtained after decoding;

[0110] The video graphics array processing module is used to generate a video graphics array signal according to the pixel information in the video memory and send it to the display screen for display.

[0111]a clock module for generating a clock signal for driving the receiving module, the decoding module, the video memory module and the ...

Abstract

The invention provides a processing method for playing video files, a device and display equipment. The method comprises the following steps: the current electric quantity of the display equipment andthe first resolution and the playing duration of a first video file are acquired, and the display equipment supplies power by a power supply with limit energy; according to the playing duration and the corresponding electric quantity consumption rate of the display equipment for displaying the video file by the first resolution, the first electric quantity needing to be consumed by the first resolution for displaying the first video file is calculated; and when the current electric quantity is less than the first electric quantity, the resolution of the first video file is reduced from the first resolution to the second resolution, a second video file is obtained, and the first display data of the second video file is sent to the display equipment. The invention reduces the energy consumption of the display equipment and leads a user to be capable of displaying video files as numerous as possible under the condition of limit energy.

Description

technical field [0001] The invention relates to the technical field of video playback processing, in particular to a video file playback processing method, device and display device, which reduce the energy consumed by the display device for video display. Background technique [0002] High-resolution wireless display mobile devices have a broad market due to their good portability and clear image quality. [0003] The wireless display mobile device receives the display data conforming to the wireless interface communication protocol from the host through the wireless interface, and then decodes the received display data by the decoding module, and sends the pixel information of the decoded video stream data to the video memory for storage. Graphics Array, video graphics array) processing module generates a VGA signal according to the pixel information in the video memory and sends it to the display screen for display. [0004] In the process of realizing the present invent...
