AI Technical Summary

Problems solved by technology

[0006] In the above scenario, it is currently impossible to solve the problem of fully automatic and perfect synchronous switching of the main and auxiliary screens of remote multi-point interactive teaching. The fundamental problem is that the local broadcasting equipment cannot uniformly analyze and manage and switch other classroom screens

Abstract

The invention discloses an audio and video switching method, an audio and video switching device and a remote multi-point interactive teaching system. The Audio and video switching method comprises the steps of: deploying audio and video signals of each classroom in a multi-point remote interactive network to the cloud synchronously, and carrying out unified analysis on the signals; switching theaudio and video signals of each classroom in the multi-point remote interactive network which are deployed to the cloud synchronously and / or display modes by adopting a preset program or method according to an analysis result; and finally transmitting the signals to different classrooms in the multi-point remote interactive network for decoding or / and display or / and recording and broadcasting or / and live broadcasting or / and broadcasting on demand separately. By adopting the audio and video switching method, the audio and video switching device and the remote multi-point interactive teaching system, the automatic switching effect of main screens of two or more different teaching places or terminals can be realized simply; through unified tracking and adopting an audio and video signal switching mechanism and an audio and video signal switching strategy, all the signals are deployed in a unified manner, the intelligent full-automatic switching effect of images in the multi-point remote interactive teaching process is realized, the full-automatic perfect synchronization switching is obtained; and the audio and video switching device achieves the same benefit effects of the audio and video switching method.

Description

technical field [0001] The invention relates to the field of multimedia teaching, computer software, video conferencing and the like, and in particular to an audio and video switching method, device and remote multi-point interactive teaching system. Background technique [0002] With the vigorous development of information technology, the remote interactive teaching technology carried by technologies such as the Internet, local area network, metropolitan area network, and campus network has gradually matured. Various software and hardware live broadcast, on-demand platforms, video conferencing and interactive teaching platforms are diverse. [0003] Figure 1(a)-(b) is a schematic diagram of the topological structure of the point-to-point distance interactive teaching system, which includes 2 classrooms; 4 cameras are deployed in each classroom, which are camera 1~4 and camera 5~ 8. It is used to collect video images such as close-ups of teachers, panoramic views of teacher...
