How many types of video conferencing are there? How do enterprises choose?

How many kinds of video conferencing?

From the current market, simple and roughly speaking video conferencing system classification mainly contains: video conferencing system hardware, video conferencing system software.

Categorized by tariffs, the classification of video conferencing systems can be divided into: per-minute billing video conferencing systems, annual video conferencing systems and buyout.

A video conferencing system hardware

Terminal aspect mainly refers to all the conference terminal is embedded architecture, dedicated machine, non-XP or XPE system transformation. Audio and video coding and decoding are completed on a dedicated chip. Terminal contains hardware capture coding card. The cameras are basically used in conjunction with each other. Advantages are stable, clear picture, very suitable for conference room use.

MCU, full coding and decoding, that is to say, all the terminals will be uploaded to the video screen decoding, and then re-encoded according to the different layout into a screen all the way to distribute. High performance on hardware.

The upstream and downstream bandwidth of the terminal is basically equivalent, and the current models can basically reach 1080P, occupying about 2M bandwidth.

The upstream and downstream bandwidth of the MCU is basically equal, and it receives as many uploaded images from the terminal as it can, and then sends out as many images as it can after combining the screens.

Two, video conferencing system software

Terminal/client side are basically relying on windows, android, ios application software, video capture rely on USB camera, PCI interface video capture card + external camera. Stability is definitely lower than the hardware terminal. The advantage is flexible, can be anywhere as long as you can network.

MCU (software is generally called server), does not encode and decode the video image, only forwarding, such as 10 people will participate in broadcasting 3-way picture, then only upload the 3-way picture, and then the 3-way flow to the 10 people distributed 3-way each. So basically the server hardware performance requirements are not high.
