摘要
H.323标准制定了无服务质量保证的分组网络上的多媒体通信系统标准,为基于网络的通信系统定义了4个主要组件:终端、网关、网闸和多点控制单元.在H.333标准中,多点会议的实现有多种方法和配置.H.323系统中的通信可以看成视频、音频和控制信息的混合.在IP网络上多媒体通信中,H.323同样有着重要作用.
The H. 323 standards specify the packet-based multimedia communication system standards with non-guaranteed Quality of Service and define four major components for the communication systems based on network, that is terminal, gateway, gatekeeper and multipoint control unit. In H. 323 standards, there are many ways and configurations for implementing multipoint conference. The communications in H. 323 system can be regarded as the hybrid of video, audio and control information. H. 323 also plays an important role in multimedia communication based on IP network.
