Video Conference

Video conference say again meeting TV, video conference, etc, which can realize in two and multi-point between real-time transmission activity image, sound and the application of data (electronic board and graphics) and other forms of information, global video conference software firstchoice brand - DX4000.

Basic concepts

Video conferences can make people more effective communication, because visualization communication is the most natural way of communication. Therefore see more people than can deepen the understanding and memory, especially when the topic itself is a very image point of view.

Some video conferencing system designed to allow several groups of people in different places in the same meeting, some are designed only allow several people in their desktop discuss project. No matter what, they could see that the comprehensive activity image, clearly heard what others say, it felt like together. In this way, the video conference created such an environment: faster underground decision-making, more powerful team work, ideas, knowledge, encourage can, from a colleague to another fellow. There is a more significant advantage is not on a business trip.

Video meeting makes people in different places in the mutual influence between them - whatever is 10 minutes of step process or 10 hour flight schedule. It can make people like in the same room as exchange ideas and exchange information. This meant that people don't waiting for E-mail, fax or express spent working hours. Briefly video meeting makes people say, "sit" together.

Video conference advantage

Video conferencing system has many advantages, and it is these advantages make video conferencing system widely recognized.

1, deploy convenient

The current mainstream configuration PC generally can serve as a video terminals, these PC installed cameras, headset and related software, through LAN or Internet access to a central server, can attend the meeting of MCU.

2, integrated data meeting

Due to the Windows operating system, based on video conference held in the meanwhile realize electronic board and program sharing, file transfer data such as meeting function, as meeting the auxiliary tool.

3, low cost

Due to the PC has been the standard configurations, office desktop conferencing terminals need not gain a lot of hardware input. While meeting room type terminal and only need buy comparative high-performance PC and video capture card can, its costs also lower than ordinary hardware video terminals.

Domestic network video conference has been the first to launch sas mode of conference system, innovation type launch renting service, network video conference is to let the cost to general enterprise can receive range.

4, use convenient

Network video conference has developed to a certain extent, also according to user's habits, use the feedback for improved the interface became humanized, people do not need too professional knowledge is able to operate, in this respect, the domestic network video conference provider manufacturer had walked

Section basic function

Video conference two basic functions required: first is the image collection and display, second is the voice of acquisition and broadcast.

Image collection mainly through digital cameras or analog camera to realize, if you want to achieve high quality graphics, must possess high pixel of CCD acquisition device, and add video capture card, in order to achieve A/D (module) conversion.

Voice of acquisition and broadcast usable CATO - 3 omnidirectional microphone, CATO - 3 have echo eliminate noise function, can people with speeches, and can hear each other's speech. Can automatically adapt to all kinds of meeting environment, for the participants provide high fidelity, clear voice.

Technical characteristics

- a famous French UI design institute development of new human user interface, the operation is more concise easy-to-use - adopts advanced P2P data transmission, support concurrent users, online number liquor unlimited expansion - realize server levels coupon, server load balance and multilayer backup, guarantee the stability of the meeting held - h. 263, support h.264, MPEG4 etc. Various decoding technology, meet different user specific requirements - can be based on user network situation differences, automatic detection and adjust the audio and video data transmission streaming size - audio decoding technology, make sound more clearly fluent - voice played by self-developed echo suppression, automatic gain, noise elimination, sound compensation technology - system built-in high-performance data engine modules, remote Shared various data files and streaming media files - powerful based on WEB of remote management function with multiple dominant mode, pledging conference orderly conduct - perfect h.323 protocol support, soft MCU can with the mainstream hardware terminal equipment interchange interconnected

Telemedicine system of another advantage is that according to the users' different needs and communications conditions, providing various specifications of hardwares proposal, convenient user choose according to its actual situation.

MCU server

MCU is video conferencing system of multi-point key equipment, semiconductor MCU future cases of information flow, after meeting sites after sync separator, extract audio video, data, such as information and signaling, then all conference sites of information and signaling, into the same kind of processing modules, complete the corresponding audio mixing or switching, video or mixed handoff, data broadcast and routing, timing and meeting control process, finally will each meeting all of the information required sites to combination rises, sent to the corresponding terminal system equipment.

Video conferencing system of MCU own nets brake function (also called nets guard). Nets brake mainly has the following functions: 1) provides conference bandwidth management conference and access control, because network bandwidth limited, to ensure quality, allowing limited meeting terminal join meeting. In addition, nets brake again can restrict some terminal access bandwidth, as far as possible allow more terminal join meeting or guaranteed some important terminal access bandwidth, 2) directory service: display the current online terminal list, it is convenient to conference. 3) and control other network area of nets brake work together, hold the network between the region meeting.

Video conference a bit like using the phone -- besides can see talk with you people outside, you can see their expressions and body language, and their approach to your words reaction. You can use the same piece of tables or any other PC file. It's like you with and what you call in the same room, face-to-face work the same.
