Abstract

Provided are a method, device, and a display device for switching video source. The method comprises: detecting and finding at least one currently available video source; displaying the video source in a video source list in the form of thumbnails, obtaining a video source selection event, switching to the selected video source from the video source list as the current video source, and displaying said video source. The present invention can at least solve the problems of low switching efficiency and abnormal switching.

First claim

1 . A method for video source switching, the method comprising:
detecting at least one video source presently available; displaying the at least one video source as a list of video sources in forms of thumbnails; acquiring an event of selecting a video source from the list of video sources, switching a present video source to the video source selected from the list of video sources, and displaying the present video source.

2 . The method according to claim 1 , wherein the detecting at least one video source presently available comprises:
detecting the at least one video source input respectively through at least one corresponding video interface, the at least one video source comprising at least one of a Video Graphics Array (VGA) input source, a High Definition Multimedia Interface (HDMI) input source, and a Graphical User Interface (GUI) video input source.

3 . The method according to claim 1 , wherein the displaying the at least one video source as a list of video sources in forms of thumbnails comprises:
acquiring the detected at least one video source and video information corresponding to the at least one video source; generating the thumbnails according to the video information corresponding to the at least one video source, and displaying the list of video sources in forms of the thumbnails.

4 . The method according to claim 3 , wherein the generating the thumbnails according to the video information corresponding to the at least one video source, and displaying the list of video sources in forms of the thumbnails comprises:
in case that the thumbnails are to be generated according to a video stream comprised in the video information, when a video stream of a video source in the at least one video source is being output normally, generating a thumbnail corresponding to the video source in the at least one video source, and displaying the thumbnail in the list of video sources; when a video stream of a video source in the at least one video source is not being output normally, setting a thumbnail corresponding to the video source in the at least one video source as an icon illustrating content of the video source, and displaying the thumbnail in the list of video sources.

5 . The method according to claim 1 , wherein the acquiring an event of selecting a video source from the list of video sources, switching a present video source to the video source selected from the list of video sources, and displaying the present video source comprises:
acquiring the event of selecting the video source from the list of video sources by clicking on a thumbnail corresponding to the video source, switching the present video source to the selected video source, and displaying the present video source in a video picture of a present participant; or, acquiring the event of selecting the video source from the list of video sources by dragging a thumbnail corresponding to the video source, switching the present video source to the selected video source, and displaying the present video source in a video picture of a present participant.

6 . A device for video source switching, the device being located in an electronic displaying equipment, the electronic displaying equipment comprising a display screen of a touch type or a non-touch type, the device comprising:
a detecting module configured for: detecting at least one video source presently available; a displaying module configured for: receiving the at least one video source reported by the detecting module, displaying the at least one video source as a list of video sources in forms of thumbnails; acquiring an event of selecting a video source from the list of video sources, switching a present video source to the video source selected from the list of video sources, and displaying the present video source.

7 . The device according to claim 6 , wherein the detecting module is further configured for: detecting the at least one video source input respectively through at least one corresponding video interface, the at least one video source comprising at least one of a Video Graphics Array (VGA) input source, a High Definition Multimedia Interface (HDMI) input source, and a Graphical User Interface (GUI) video input source.

8 . The device according to claim 6 , wherein the displaying module further comprises a first displaying sub-module configured for:
acquiring the detected at least one video source and video information corresponding to the at least one video source; generating the thumbnails according to the video information corresponding to the at least one video source, and displaying the list of video sources in forms of the thumbnails.

9 . The device according to claim 6 , wherein the displaying module further comprises a second displaying sub-module configured for:
acquiring the event of selecting the video source from the list of video sources by clicking on a thumbnail corresponding to the video source, switching the present video source to the selected video source, and displaying the present video source in a video picture of a present participant; or, acquiring the event of selecting the video source from the list of video sources by dragging a thumbnail corresponding to the video source, switching the present video source to the selected video source, and displaying the present video source in a video picture of a present participant.

10 . A displaying device, the displaying device comprising a display screen of a touch type or a non-touch type, the displaying device comprising:
a display configured for: displaying acquired at least one video source as a list of video sources in forms of thumbnails; acquiring an event of selecting a video source from the list of video sources, switching a present video source to the video source selected from the list of video sources, and displaying the present video source.

11 . The device according to claim 10 , wherein the display comprises a first displaying unit configured for:
acquiring the detected at least one video source and video information corresponding to the at least one video source; generating the thumbnails according to the video information corresponding to the at least one video source, and displaying the list of video sources in forms of the thumbnails.

12 . The device according to claim 11 , wherein the first displaying unit is further configured for: in case that the thumbnails are to be generated according to a video stream comprised in the video information, when a video stream of a video source in the at least one video source is being output normally, generating a thumbnail corresponding to the video source in the at least one video source, and displaying the thumbnail in the list of video sources; when a video stream of a video source in the at least one video source is not being output normally, setting a thumbnail corresponding to the video source in the at least one video source as an icon illustrating content of the video source, and displaying the thumbnail in the list of video sources.

13 . The device according to claim 10 , wherein the display comprises a second displaying unit configured for:
acquiring the event of selecting the video source from the list of video sources by clicking on a thumbnail corresponding to the video source, switching the present video source to the selected video source, and displaying the present video source in a video picture of a present participant; or, acquiring the event of selecting the video source from the list of video sources by dragging a thumbnail corresponding to the video source, switching the present video source to the selected video source, and displaying the present video s
