Video conferencing system, also known as conference television system, refers to individuals or groups in two or more different places, through the transmission line and multimedia equipment, through the transmission of sound, video and document data, real-time and interactive communication, System equipment for remote conferencing. The use of video conferencing is a bit like a phone call. In addition to being able to see the people you talk to and communicate in language, you can also see their expressions and movements, so that people in different places can communicate in the same room.
The video conferencing system is a specific application of multimedia technology in real-time remote real-time interaction, and has the following main features.
1. Real-time interactive features. Real-time interactive function
The most prominent feature of the conference system is that the remote remote LED display interacts in real time, and simulates face-to-face communication through a remote network, that is, it has a two-way video and audio real-time data transmission sharing function.
2. Multi-point communication function. Multipoint communication function
The video conferencing system can complete the synthesis and distribution of sounds and images through a multi-point control unit. Similar to the function of streaming media, a general video conferencing system can connect multiple sub-site scenes and simultaneously communicate with each other, which can support 2 to The 8 point video conference is carried out, and its large dependence factor has a relatively large relationship with the network operating environment.
3. Multi-stream integration. Multistream integrated function
In modern conferences and academic exchanges, data sharing is becoming more frequent. Therefore, in addition to the general video and audio signals, the video conferencing system has the ability to synchronize the multimedia signals output by the desktop screen, the electronic whiteboard and some other experimental devices, and realize real-time interaction and sharing of various multimedia data.
4. easy to use. Simplicity of operator
The mature video conferencing system adopts a very human-friendly human-computer interaction interface, which can be conveniently and quickly controlled by using various methods such as a remote controller and a touch screen, and is easy to use.
The feasibility of video conferencing in the industry.
1. It has a high degree of unity with the education industry management work mode.
2. High quality network operating environment.
3. Video conferencing system is an important direction for educational audio-visual media applications.
One of the important application directions of the education network is the interactive application of audiovisual media. The conference system is one of the three major video systems commonly used in the education industry; from the application level, it is also an indispensable solution in practical applications such as on-site teleconference, seminar, evaluation and training. It can be seen that LED display has an irreplaceable position and role in the education industry.
