DVI-ECO video conference system can get rid of time, space limits effectively, and realize face to face communication anytime and anywhere. It not only reduces operation cost of enterprise, but also it can improve work efficiency and decision response speed. So the video conference system has been widely approved by users.

The video conference system has been increasingly significant role in the industry organization of government, finance, energy, communication, transportation, medical treatment, education etc. While users reach a certain dependence degree for the video conference system, then security and stability system will be a key measure.

The video conference terminal as video conference unit will affect directly if the conference processes normally, so it is essential for the necessary backup measures. When the conference system is a failure in traditional backup scheme, point of failure needs to be judged by human. If the conference terminal is a failure, then the backup conference terminal will be enabled by human to cover the video conference system. The scheme is cold backup, its disadvantage is that the conference will be forced to interrupt until the backup conference terminal is stated, it may take 5~10 minutes.

In order to reduce the troubleshooting of system failure and avoid the failure of conference terminal leading to be forced to interrupt the video conference, the DVI-ECO seamless intelligent switcher that Dalian GigaTec researches and develops exclusively can realize automatic test and automatic switch for main and backup conference terminal output signal. The main and backup conference terminal are enabled simultaneously, when the main conference terminal is without output signal, the DVI-ECO will detect abnormal signal for the first time, at the same time it will be static frame output for the last frame image before abnormal signal. Like this it can avoid video signal interrupting, at the same time the DVI-ECO will be switched automatically to backup conference terminal and it can realize seamless switch for video. Signal switching time is 1 frame, so users can enable backup conference terminal when the participants do not still detect any abnormal situation, finally it will make the conference normally. The equipment will be sophisticated “powerful tool” in the medium, high-end video conference system.
