The invention is used for solving the issue existed in currently-used technology that is the video service users can not select image-displaying mode according to their needs. The method thereof comprises: multi-point controller receives a switch request message comprising the amount of sub-images indicated by the image-displaying mode; according to the image-displaying mode the multi-point controller determines the image mixer required by the image-displaying mode, and outputs the images corresponding to the image-displaying mode to the user end sending the switch request message.
Description
technical field The present invention relates to multimedia video technology in the communication field, in particular to a method, device and system for realizing screen switching in video services. Background technique The video conferencing system allows conference participants to exchange voice, video and data in real time, which greatly facilitates the communication and communication between conference participants. In the network structure of the video conferencing system shown in Figure 1, a multipoint control unit (MCU, Multipoint Control Unit) is connected to each site participating in the conference, and is used to receive site signals, process site signals, and send the processed site signals to Various venues participating in the meeting; user terminal equipment mainly realizes the input and output of voice, image and data, as well as communication connection and data sending and receiving functions; more than two user terminal equipment and MCU build a multi-po...
