Analysis of the development process of video conference and future operation market
Video conferencing system
The video conferencing system consists of a video conferencing terminal, a multipoint control unit MCU, network management software, a bearer network, and related accessories. Because the existing network conditions and hardware facilities of the users are different, the specific requirements for each part of the video conferencing system are also different. The details are as follows:
Multipoint control unit MCU
The MCU is the core part of the video conferencing system, also known as the video conferencing server. The main function is to coordinate and control the video transmission between multiple terminals. When the number of terminals participating in the conference is more than two, the MCU must be used to control the conference. All terminals must connect to the MCU through standard interfaces to provide users with group conferences and connection services for multiple conferences. The MCU implements functions such as mixing and exchanging voice and images and controlling all venues according to a series of standards.
The MCU is mainly divided into two parts, namely MC (MultipointController) and MP (MultipointProcessor). MC is mainly responsible for coordinating the sequence of transmission channels between terminals and using H.245 and other series of standards to define the specifications of the transmission content; MP is actually engaged in the reproduction, transfer and some video of audio and video under the control rules of MC. Stream processing. In the MCU, the MC is a management function that must be provided, and the MP has a choice between the terminal's ability to handle the video and the overall environment architecture.
Video systems often use a star network approach, and all terminals are connected to the central MCU. When the number of terminals is large, a single machine cannot provide all user access. The MCU can be expanded by means of cascading. The MCU in the network is called the main MCU, and the MCU is connected to the MCU. Connect to the MCU to meet the needs of more terminals to join the conference at the same time. The use and management of the MCU needs to be simple and easy to use, so that the average employee in the customer can operate.
Video conferencing terminal
There are mainly desktop, set-top box, conference room and telepresence. Introduced as follows:
Desktop terminal
With the globalization of the business environment, the need for enterprise employees to travel long distances and low-cost instant communication is becoming more and more urgent, and the desktop video conferencing system just caters to this demand. Desktop (PC) terminal products Desktop conferencing is a video conference directly on the computer, combined with camera, ISDN card, network card and video conferencing software. The desktop video conferencing terminal is usually allocated to a special individual in the office or a staff member who is on a business trip. Under normal circumstances, it can only be used by 2-3 people. It can be used as a general computer or as a conference terminal. It is to realize conferences, data, etc. A platform for integrated applications. It is simple and low cost.
2. Set-top box terminal
Set-top box terminals are known for their simplicity, and are suitable for organizations of all sizes, from multinational corporations to small enterprises. Set-top box terminals are usually shared resources between departments. It is also often the first "conference room type terminal" purchased by the company. All the hardware and software are contained in one unit and placed on the TV. Easy to install and lightweight. Opening a video conference requires only an ordinary TV set and an ISDN BRI line or LAN connection. The video conferencing terminal can also load peripherals such as document projectors, scanners and printers, and whiteboard devices to enhance functionality.
3. Conference room terminal
The conference room solution is almost the most comprehensive solution for all industries, medium and large enterprises. This program is generally integrated in a conference room. Conference room terminals typically combine a large number of accessories such as audio systems, add-on cameras, document projectors, and PC collaborative file video communications.
The dual-screen display, rich communication interface, and graphic selection make the terminal a high-end, comprehensive product. Specially designed, fully functional, installed in a specific conference room, can not be moved at will, can achieve complex video conferencing applications.
