Video switching method based on multi-channel decoding

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.

(10) The technical solution set forth in the present invention comprises a video switching method based on multi-channel decoding.

(11) 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;

(12) a system desktop launcher is provided, and after the system desktop launcher is started, a main interface is formed;

(13) as shown in FIG. 1, the video switching method comprises following steps:

(14) Step S1, starting the intelligent device to accomplish an initialization operation of a system file;

(15) Step S2, closing the display of the image layer, decoding an obtained boot video and displaying the boot video on the video layer;

(16) Step S3, after the system desktop launcher is started, displaying the main interface on the image layer in a transparent form;

(17) Step S4, 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

(18) Step S5, decoding remotely obtained video data and displaying the video data on the display layer by the system desktop starter.

(19) For the prior art, after the intelligent device is started, it is required to wait for the video data of the online video to be loaded after the boot video ends, so as to complete the playing of the online video. However, by adopting the play mode, a user may have to wait for a relatively longtime.

(20) In the present invention, based on the multi-channel decoding mode, after the intelligent device is started, in the process of playing the boot video, the main interface is displayed in the image layer in a transparent form so as to prevent the main interface from covering the video layer. Then a display layer superimposed on the video layer is created, and the intelligent device decodes the obtained video data of the online video and displays the obtained video data of the online video on the display layer for playing the video data, such that the online video can be simultaneously played in the display layer when the boot video is playing, avoiding the issue that the intelligent device in the prior art has to wait for the loaded video data to be played after the boot video ends, resulting in a relatively long waiting time and lowering the user experience.

(21) In a preferred embodiment, a boot player is provided, in Step S2, the boot player closes the display of the image layer and displays the loaded boot video in the video layer.

(22) In the above-mentioned technical solution, 15 seconds of play duration of the boot video is preferred.

(23) In a preferred embodiment, 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.

(24) In the above-mentioned technical solution, after the system desktop launcher is started, a display attribute of the main interface is set such that the background image and the view framework are in a transparent form, that is, invisible. In this way, the main interface is displayed in a transparent form, avoiding shielding the video layer below.

(25) In a preferred embodiment, 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;

(26) 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.

(27) In the above-mentioned technical solution, after it is determined that the boot video ends through the monitoring module, performing an operation on the main interface. The system desktop launcher then changes the display attribute of the main interface set previously to be visible. After it is set, the main interface is displayed in the image layer, covering the video layer;

(28) if the online video has not completed playing, the video data continues being played in the display layer until the video data ends, and the main interface is fully displayed in the image layer after the display layer is closed.

(29) In a preferred embodiment, as shown in FIG. 2, the boot video provides a play-ending flag bit, and a method for monitoring whether the boot video playback ends through the monitoring module comprises:

(30) Step A1, the monitoring module providing a monitoring thread which is configured to be started when playing the boot video;

(31) Step A2, the monitoring thread monitoring whether the play-ending flag bit is present or not;

(32) if the result shows “NO”, returning to Step A2;

(33) if the result shows “YES”, proceeding to Step A3;

(34) Step A3, 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.

(35) In the above-mentioned technical solution, it can be accurately determined whether the boot video ends through the play-ending flag bit. If the play-ending flag bit is detected, 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.

(36) In a preferred embodiment, display coordinates of the display layer are located at a lower left corner of the image layer.

(37) In the above-mentioned technical solution, the display layer can be displayed at any position of the image layer, preferably at the lower left corner of the image layer.

(38) In a preferred embodiment, the display layer has a display size of 480*270.

(39) In a preferred embodiment, after Step S5, after the boot video ends, the display size of the display layer is switched to a full screen display status of the image layer.

(40) In a preferred embodiment, after Step S5, 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.

(41) In the above-mentioned technical solution, in the process of playing the boot video, sound associated with the boot video can be heard. If the boot video has not completed playing, the video data played in the display layer is in a mute state. Only when the play-ending flag bit is detected can the display size of the display layer is switched to a full screen display status of the image layer, furthermore, the video data displayed in the image layer is adjusted from a mute state to a voiced state.

(42) The above descriptions are only the preferred embodiments of the invention, not thus limiting the embodiments and scope of the invention. Those skilled in the art should be able to realize that the schemes obtained from the content of specification and drawings of the invention are within the scope of the invention.
