Design And Realization Of Comprehensive Video System

Today change with each passing day, the network has already become the exchanges way of a necessary kind of the many people in the Internet technique. Network and multimedia are technical of developed to provide the video frequency meeting of the means-network of the new generation correspondence a technique for people continuously. Differ from traditional meeting mode, the network video frequency meeting asks for help from Internet this strong tool, breaking the restriction of space, providing a kind of exchanges that body faces its at people of world-wide locations for the dispersal. Video system experienced government, business, medical treatment, education...etc. a lot of realms all have an extensive application.This text mainly carried on more thorough analysis and research to existing international standard, related technique of the video frequency meeting, and combined actual item, developing 1 system according to the video frequency meeting of the network, design and carried out total frame and each one of system. This text mainly did a following work:1. Carried on a thorough research to the current meeting technical main and international standard of the network video frequency and the related agreement and compare, the key technique which analyzes to set up a video frequency meeting system orders.2. The video frequency meeting combined correspondence technique, multi-media technique and control technique, studied and analyzed to carry out according to the pure software of network the main function of the system and set up a method, designed the total structure model of comprehensive video system.3. Analyzed function and design project of each layer of system in detail, carried out terminal to connect go into, meeting, data meeting, charge management, business statistics, the business flow etc. function.4. Studied current main video frequency portrait to compress calculate way, design and carried out the video frequency of the comprehensive video system correspondence.5. For comprehensive video system many order the center work of the resources management more principle, many the class order the resources management center set more the net is applied and many to order resources management more center of the function characteristics carry on a research.6. In physically applied, the electronics whiteboard, document which carries out video system delivers, in many ways confabulation, apply to share function.
