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 invention relates to the technical field of video conferencing 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 long-distance distance education in the prior art, such as figure 1 As shown, the video sub-picture of the lecturer, the video sub-picture of the interactive classroom, and the video graphics array (Video Graphics Array, referred to as VGA) auxiliary video sub-picture are respectively displayed on the terminal screen, and the VGA secondary video is displayed on the largest sub-picture middle. [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 v...
