Abstract

The invention discloses a device and method for automatically switching video sub-pictures. The device for automatically switching video sub-pictures comprises a media control module, a media receiving / transmitting module and a multi-picture combining module, wherein the media control module is used for transmitting auxiliary video control instructions to the media receiving / transmitting module and the multi-picture combining module under a condition that an auxiliary video of a broadcast terminal is determined to be transmitted; the media receiving / transmitting module is used for transmitting the media code stream of the auxiliary video obtained from the broadcast terminal to the multi-picture combining module according to the instructions of the media control module and transmitting a combined multi-picture media obtained from the multi-picture combining module to other terminals; and the multi-picture combining module is used for combining the received media code stream with the current media picture according to the instructions of the media control module to obtain a combined multi-picture media and transmitting the combined multi-picture media to the media receiving / transmitting module.

Description

Technical field [0001] The present invention relates to the technical field of video conference systems, in particular to a device and method for automatically switching video sub-pictures. Background technique [0002] At present, in real-time interactive visual distance education, it is usually necessary to realize 3-screen display. figure 1 It is a schematic diagram of terminal screen display in real-time interactive visual distance education in the prior art, such as figure 1 As shown, the video sub-picture of the instructor, the video sub-picture of the interactive listening room, and the auxiliary video sub-picture of Video Graphics Array (VGA) are displayed on the terminal screen respectively, and the VGA auxiliary video is displayed in the largest sub-picture . [0003] When the VGA video is stopped or paused, the screen switches to 2 screens, figure 2 It is a schematic diagram of the terminal screen display when the VGA video is stopped or paused in the prior art, such as...
