What is video Conference System?

The so-called Video Conference System refers to an individual or group of two or more different places, through the transmission line and multimedia equipment, the video, sound and file data are transmitted to each other to realize instant and interactive communication system equipment.The video conferencing system is widely used in video conferencing, distance education, telemedicine, e-government, collaborative office, online training, etc. It can be widely used in government, military, enterprise, IT, telecommunications, electric power, education, medical, financial and other fields.

At present, video conferencing systems mostly use MCU (Multi-point Control Unit), including central platform equipment, system management software, terminal equipment, software terminals, video and audio equipment, transmission systems and other parts. In this structure, the MCU is used as the central platform device, other devices access the MCU through the terminal devices of each sub-site to centrally perform data processing, network processing, and conference management to form a complete video conference system. Further, a larger-scale networking can be performed by multi-stage cascading of multiple MCUs or multi-machine stacking of the same level.

Generally speaking, MCU structure video conferencing system including below equipment:
