What is a video conferencing terminal?

What is the video conferencing terminal, which is used to encode, package, and transmit video and audio data to the remote end over the network. The device that receives the data transmitted from the remote end, performs unpacking and decoding, and contacts the network with the end user to implement the network application is called a video conference terminal.

What does it do in the video conferencing system?

1, data letter input and output

Generally, the video and audio input to the terminal are analog signals. The terminal's I/O module will digitize them into digital video and audio signals.

2, compression decoding

3, channel transmission

It includes caching of digital video, error correction coding, multiplexing/demultiplexing of various media signals, and functions such as terminal and channel interfaces.

4, system control

The system control module in the terminal device performs control functions on the I/O module, the codec module, and the channel transmission module. The control module also undertakes the end-to-end and end-to-network signaling transmission in the video conferencing system, and provides channels for the user to the terminal device and the communication system.
