Abstract

The present invention provides a video switching method based on multi-channel decoding and comprising: starting the intelligent device to accomplish an initialization operation of a system file; closing the display of an image layer, decoding and displaying an obtained boot video on the video layer; after a system desktop launcher is started, displaying a main interface on the image layer in a transparent form; after a system is started, the intelligent device creates and displays a display layer on the image layer, wherein a display area of the display layer is smaller than that of the image layer; and decoding and displaying remotely obtained video data on the display layer. The invention avoids the issue of waiting for the loading of the video data of the online video for playing after the boot video ends, resulting in a relatively long waiting time and lowering the user experience.

First claim

What is claimed is:

1. A video switching method based on multi-channel decoding, applied to the boot of an intelligent device, wherein a video layer and an image layer located on the video layer are provided, and the video layer is configured to play a boot video;
a system desktop launcher is provided, and after the system desktop launcher is started, a main interface is formed;
the video switching method comprises following steps:
Step S 1 , starting the intelligent device to accomplish the initialization operation of a system file;
Step S 2 , closing the display of the image layer, decoding an obtained boot video and displaying the boot video on the video layer;
Step S 3 , after the system desktop launcher is started, displaying the main interface on the image layer in a transparent form;
Step S 4 , after a system is started, the intelligent device creates a display layer and displays the display layer on the image layer, wherein a display area of the display layer is smaller than that of the image layer; and
Step S 5 , decoding remotely obtained video data and displaying the video data on the display layer by the system desktop starter;
wherein after the system is started, the intelligent device starts a monitoring module while creating the display layer, and monitors whether the boot video ends through the monitoring module; and
wherein the system desktop launcher operates to change a display content of the main interface from an invisible transparent state to a state of a visible operation interface when the boot video ends.

2. The video switching method as claimed in claim 1 , wherein a boot player is provided, wherein in Step S 2 , the boot player closes the display of the image layer and displays the loaded boot video in the video layer.

3. The video switching method as claimed in claim 1 , wherein a method for displaying the main interface on the image layer in a transparent form comprises setting a background image and a view framework in the main interface to be invisible.

4. The video switching method as claimed in claim 3 , wherein the boot video provides a play-ending flag bit, and a method for monitoring whether the boot video ends through the monitoring module comprises:
Step A 1 , the monitoring module providing a monitoring thread which is configured to be started when playing the boot video;
Step A 2 , the monitoring thread monitoring whether the play-ending flag bit is present;
if the result shows “NO”, returning to Step A 2 ;
if the result shows “YES”, proceeding to Step A 3 ;
Step A 3 , the system desktop launcher operating to change a display content of the main interface from an invisible transparent state to a state of a visible operation interface.

5. The video switching method as claimed in claim 1 , wherein display coordinates of the display layer are located at a lower left corner of the image layer.

6. The video switching method as claimed in claim 1 , wherein the display layer has a display size of 480*270.

7. The video switching method as claimed in claim 1 , wherein after Step S 5 , after the boot video ends, the display size of the display layer is switched to a full screen display status of the image layer.

8. The video switching method as claimed in claim 1 , wherein after Step S 5 , after the boot video ends, the display size of the display layer is switched to a full screen display status of the image layer, and the video data displayed in the image layer is adjusted from a mute state to a voiced state.
