Description
Technical Field
The invention relates to the technical field of video conferences, in particular to a dynamic authentication and registration system for a large-capacity video conference terminal.
Background
Under the influence of epidemic situations, video conference systems and equipment are used more and more frequently at present, and even all levels of courts can also widely use the video conference systems and equipment in the court trial process. The video conference system mainly has the problem of large interference, for example, in an office building, conference rooms of a company are distributed densely in a plurality of rooms which are closely connected in a certain floor. In this scenario, a plurality of video conference devices are densely distributed in a limited space, and if the video conference devices are connected with a conference service provider server in a wired communication manner, the video conference effect is not significantly affected by the dense distribution. However, if the video conference devices are connected with the conference service provider server in a wireless communication manner, different video conference devices will interfere with each other, and further, problems such as frame skipping, blocking, unclear sound, uncoordinated audio and video, etc. occur during the video conference. If the interference occurs in the video access, authentication and registration stages, a long-time unsuccessful registration problem may be caused. The communication capacity of a video conferencing system would still be able to gain a considerable degree if the interference problem could be mitigated.
