网络的视频聊天(Desktop Video Conference),是利用视频技术和IP数据通信技术通过IP网络(Internet、Intranet、LAN/WAN)在两点或多个地点之间建立可视通信,实现图像、语音及数据交流的一种聊天形式。与会者利用PC终端、摄像机和话筒既能实时地看到对方发言人和会场场景,也能听到对方的声音,若辅以电子白板、书写电话、传真机等通信设备,即可实现与对方会场的与会人员进行研讨或磋商,在效果上完全可以代替现场聊天。作为一种现代化的多媒体通信工具,它在及时召开重要聊天、作出重要决策、发布重要信息、提高工作效率、节约时间和经费开支等方面的重要价值已逐渐为人们所认识。
视频聊天系统是指通过现有的各种电气通讯传输媒体,将人物的静、动态图像、语音、文字、图片等多种资料分送到各个用户的计算机上,使得在地理上分散的用户可以共聚一处,通过图形、声音等多种方式交流信息,增加双方对内容的理解能力。
视频聊天系统对应用环境的需求: 聊天设备--视频聊天系统传送的是多媒体数据,与普通数据不同,由于声音和动态图像的源信号的数据量较大,无法直接在一般条件的数字线路上传输。同时,基于对实际使用效果的要求,用户还要求传送的声音、图像信号连续平滑,其它辅助功能使用简捷。因此,要达到这样的效果,系统在声音/图像压缩、通讯线路条件、视频聊天系统现行的标准: 国际电信联盟ITU对于视音频通讯及其兼容性的技术进行了规范,在这些基本的协议中,同时对语音、视频的编码格式,用户控制模式等要件进行了相关的规定。ITU-T制定的适用于视频聊天的标准有: H.320协议(用于ISDN上的群视频聊天)、H.323协议(用于局域网上的桌面视频聊天)、H.324(用于电话网上的视频聊天)和H.310(用于ATM和B-ISDN网络上的视频聊天)。其中H.323协议成为目前应用最广最通用的协议标准。

IP-based video conferencing (Desktop Video Conference), is the use of video technology and IP data communication via IP network (Internet, Intranet, LAN / WAN) two or more locations in the visual communication between, Image, voice and data communications in the form of a meeting. Participants use PC terminals, cameras and microphones can not only see each other in real time and venue spokesman scenes can hear each other's voice, if supplemented by electronic whiteboard, writing telephone, fax and other communications equipment, can be realized with each other participants to discuss the venue or consultations, in effect, can replace on-site meeting. As a modern multi-media communication tools, it is timely and important meeting, important decisions to make, publish important information, improve efficiency, saving time and money to the important value of the expenditure has gradually been recognized.
Video conference system is the variety of electrical communication through the existing transmission media, the people of the static and dynamic images, audio, text, pictures and other information distributed to each user's computer so that geographically dispersed users can copolymerization of a, through graphics, sound and other means to exchange information, increase the ability to understand both the content.
Video conferencing system to the application environment: meeting facilities - video conferencing system to send the multimedia data, different from ordinary data, sound and moving images as the source of large amount of data signals can not figure directly in line with the general conditions transmission. Meanwhile, based on the practical effects of the request, the user also requested to send voice, image signal continuous smooth, simple to use other accessibility features. Therefore, to achieve such results, the system sound / image compression, communication line conditions, the current standard video conferencing system: the International Telecommunication Union ITU and its compatibility for video and audio communications technology from the norm, the agreement on these basic the same time voice, video encoding format, the user control mode elements were the relevant requirements. Developed by ITU-T standard for video conferencing are: H.320 protocol (for group video conferencing on ISDN), H.323 protocol (for LAN, desktop video conferencing), H.324 (for telephone Online video conferencing) and H.310 (for ATM and B-ISDN video conferencing on the network.) H.323 protocol which became the most widely the most common protocol standards.
