The main principle is to combine the audio and video collection equipment of the conference terminal with the data transmission system, and then have a unified central control unit for regulation, so that people in different regions can Communicate and interact in a video conferencing system. Its main components include terminal equipment, data transmission network and central control unit.

1.A terminal device refers to a device that completes human-computer interaction in a video conferencing system. Including camera, microphone, display, computer, etc., mainly used for audio, video, related physical information collection, conversion, upload, receive, restore playback and perception. Through them, audio, video, data acquisition and other information are processed separately and then synthesized into one or more digital code streams by professional conference equipment, and then converted into a data format suitable for network transmission, and sent to the channel for transmission. Transmission, enabling participants in each venue to clearly see the scenes of other conferences, and to discuss issues and shared data and other powerful features.

Second, the application of video conferencing system

With the continuous development of electronic information technology and network communication technology, the application of video conferencing has gradually expanded in more fields. At present, video conferencing systems are mainly in government, telemedicine, distance education and training, remote business meetings and project collaboration. Applications in areas such as work applications.

1.      Government administrative meetings often have complex procedures and are very frequent. China has a vast territory and an uneven population distribution. It takes a lot of time and labor costs to bring together government personnel from different regions to conduct meetings. Video conferencing can be effective. To solve this problem, and to be efficient and intuitive in the transmission of documents, it is conducive to the communication of the spirit of the meeting, and is also conducive to the timely implementation of the meeting instructions by the participants at the lower level.

2.      In telemedicine, video conferences are used to realize the consultation, guidance treatment and nursing, and medical training for grassroots medical personnel in central hospitals and grassroots hospitals. The high-quality video service makes it possible for doctors and nurses to work together in different places. Especially for the consultation of emergency diseases, medical experts from different regions are not allowed to come together for discussion in time, so telemedicine has become the most effective measure. In addition, telemedicine has important significance for some small and medium-sized hospitals, and can receive timely advice and guidance from medical experts in large hospitals.
