For example, the provincial conference system a has terminals a1, a2, a3, a4, the city 1 conference system B has terminals B1, B2, and the city 2 conference system C has terminals C1, C2. The terminals a1, a2, b1, b2, c1, c2 establish a cascading video conference to play a meeting according to the requirements. The meeting person lists are a1, a2, b1, b2, c1 and c2. At this time, the user can additionally add a provincial terminal without meeting requirements as a meeting monitoring terminal, and supposing a3, the user only needs to set the layout display of a3 as the main stream of the fusion stream, select and select the fixed picture, then set the multi-picture layout on the modified meeting page, and start multi-picture round inspection. At this time, a3 can be used for video conference picture monitoring and conference sound can be heard. Because the conference multi-picture round robin has realized the cross-stage cross-domain round robin, and the round patrol video stream requests as required, the monitoring picture of a3 also naturally realizes the cross-stage cross-domain round robin effect. At the moment, multiplexing of the conference multi-picture fusion round and the video wall conference picture monitoring round is realized. If the multi-picture layout requirement of video wall conference picture monitoring is different from the conference multi-picture layout requirement, the custom layout can be configured aiming at a3, and special multi-picture layout and multi-picture round-robin parameters can be set for the custom layout. If there is a multi-party monitoring requirement, an idle terminal, such as a4, can be additionally added, and the picture is set as a 'fixed picture', so as to realize the multi-point picture monitoring requirement.

In the foregoing embodiment, the screen configuration of one or more idle terminals in the cascaded video conference is set to "fixed screen", and these terminals that are "fixed screen" are filtered in the screen conference control operation for the whole conference participants so as to always maintain one fixed screen output for realizing the video conference screen monitoring purpose. The video wall wheel inspection configuration is realized in the conference control page of the video conference system uniformly, a special configuration entrance when a conference picture is on the wall is removed, and the integral usability of the conference system is improved. The special decoding equipment for the television wall is removed, such as 'television wall terminal' or 'encoding and decoding matrix'. Any one or more idle terminals in the conference system can be used for conference picture monitoring. The system overall construction cost is saved, the flexibility of system resource calling is improved, and the complexity of system management and maintenance is reduced.
