Warm backup multi-format switching system and method for video conference

Abstract

The invention discloses a warm backup multi-format switching system and a warm backup multi-format switching method for a video conference, the warm backup multi-format switching system including a video signal detection module, an audio signal AD module, a video and audio switching module, a video signal processing module, an audio signal DA module and a signal direct connection module, wherein the video signal detection module identifies video signals sent by a master video conference terminal or a standby video conference terminal and detects abnormality and break-off of the video signals, and converts the video signals into signals with unified format; the video and audio switching module is used for achieving seamless switching of video and audio digital signals output by the master video conference terminal or the standby video conference terminal, when meeting switching conditions. The warm backup multi-format switching system and method for the video conference, the warm backup mode is adopted for preventing that the video conference from being forcibly broken off by faults of conference terminals, the troubleshooting difficulty of fault points is reduced; meanwhile, the consistency of the video signals is ensured by the seamless switching effect, and automatic switching between the master signals and the standby signals can be achieved without being noticed by conventioneers.

Description

technical field [0001] The invention relates to the technical field of video conferencing systems, in particular to a hot backup multi-format switching system and method for video conferencing. Background technique [0002] Video conferencing terminal is the core equipment of video conferencing, the reliability of its signal transmission directly affects the normal operation of video conferencing, so necessary backup measures are essential. [0003] The traditional backup solution is to deploy dual terminals and dual-line access in the same venue, and implement cold backup, that is, the main and backup terminals are interconnected through the matrix and peripherals. When the video conferencing system fails, it is necessary to manually judge the fault point, and if the video conferencing system terminal fails, it is necessary to manually switch the matrix to enable the backup conference terminal to access the system and restore the video conferencing system; the obvious disad...

Problems solved by technology

When the video conferencing system fails, it is necessary to manually judge the fault point, and if the video conferencing system terminal fails, it is necessary to manually switch the matrix to enable the backup conference terminal to access the system and restore the video conferencing system; the obvious disadvantage of this solution is It is difficult to judge the fault point, and the manual troubleshooting is not timely, and the meeting will generally be interrupted
