Video conference system brief introduction and application contrast

Video conference is an innovative meeting mode in the era of modern technology network. Before this pattern emerged, if you wanted to have a meeting in a different place, you could only use conference call technology, and the attendees could only hear each other's voices. After the video conference system, the way of meeting communication was greatly enhanced by the introduction of visual factors.

The current video conference system can be divided into three kinds, one kind is large video conference system, applied to the national government troops and large enterprises and institutions, the system has very good effect, including MCU of hardware system, the relative price is very high; The second is the medium-sized video conference system, which provides lightweight MCU. The conference software system is relatively simple and can be used for general companies and enterprises, but the price is relatively high. The last one is pure software realization of video conference system, which USES powerful software company, offering a software platform development of economic and practical video conference system, applicable to meeting request is not high. This kind of conference software can provide the function of multi-person interactive meeting without MCU.

Modern video conference system technology and related standards, combined with network streaming media technology and Microsoft DirectShow streaming technology, a detailed analysis to design a kind of video conference system framework based on DirectShow realize. On this basis, according to the design principle of video conference system, the demand analysis and summary design of video meeting system are given according to the requirements of the project. Visual C++ 6.0 combined with DirectShow to build the video conference system to complete the functions of point-to-point meetings, multicast meetings and data conferences.
