Embodiment 1

[0051] This embodiment provides a method for switching and displaying multiple video streams. Preferably, the method is implemented based on the android system, and can be applied to equipment such as mobile terminals (such as mobile phones, IPADs, etc.), computers, such as figure 1 As shown, the method includes the following steps:

[0052]S1. Determine whether each video stream receiving channel has received newly pushed video stream information. For example, compared with the video stream information being received, when the video stream receiving channel has received newly pushed video stream information, a Notification information, according to the notification information, it is judged that there is newly pushed video stream information received. The type of video stream information includes one or more of image information at the sending end, PC screen information, electronic whiteboard information, or locally collected image information. Each channel of video stream in...

Embodiment 2

[0071] This embodiment provides a multi-video stream switching display device, preferably the method is implemented based on the android system, and can be applied to equipment such as mobile terminals (such as mobile phones, IPADs, etc.), computers, such as Figure 4 shown, including:

[0072] The first judgment unit 1 is used to judge whether there is newly pushed video stream information received in each video stream receiving channel, and the type of the video stream information includes the image information of the sending end, PC screen information, electronic whiteboard information or locally collected For image information, each channel of video stream information includes only one type of video stream information and is received through a corresponding channel.

[0073] The first association unit 2 is used to change the channel currently associated with the first renderer to be associated with the second renderer when the newly pushed video stream information is recei...

Embodiment 3

[0091] This embodiment provides a video conference management system, including a display device for switching between multiple video streams. The multi-video stream switching display device includes a first judging unit 1, which is used to judge whether there is newly pushed video stream information received in each video stream receiving channel, and the type of the video stream information includes image information of the sending end, PC screen information , electronic whiteboard information or image information collected locally, each channel of video stream information includes only one type of video stream information and is received through a corresponding channel.

[0092] The first association unit 2 is used to change the channel currently associated with the first renderer to be associated with the second renderer when the newly pushed video stream information is received, and the first renderer is used to display the video stream information The interface is displa...

Abstract

The invention discloses a multi-video stream switching display method, comprising the following steps: judging whether each video stream receiving channel receives newly pushed video stream information, wherein the video stream information comprises image information of a sending end, PC screen information, electronic whiteboard information or locally collected image information, and each path of the video stream information is received by a respective corresponding channel; when the newly pushed video stream information is received, makinga channel associated with a first renderer at present to be associated with a second renderer, wherein the first renderer is used for displaying the video stream information on a display interface in a large image display mode, and the second renderer is used for displaying the video stream information on the display interface in a small image display mode; and associating the channel receiving the newly pushed video stream information with the first renderer. The method, the device and the video session management system disclosed by the invention will not change the size of a display image, and the user experience is good.

Description

technical field [0001] The invention relates to the technical field of multimedia processing, in particular to a multi-video stream switching display method, device and video conference management system. Background technique [0002] In traditional video conferencing, most of the participating terminals (especially mobile terminals) display the received video stream in the display style of large and small screens, that is, the large screen displays the image of the sending end, and the small screen displays the locally collected image, for example, Tencent QQ chat This is how the chat video window in the room appears. [0003] However, when the participating terminals receive multiple video streams (currently, multiple video streams generally include image information at the sending end, PC screen information, electronic whiteboard information, locally collected image information, etc.), the above-mentioned traditional display methods are no longer able to display The vide...
