The H.323 standard provides a foundation for audio, video, and data communications across IP-based networks, including the Internet. H.323 is an umbrella recommendation from the International Telecommunications Union (ITU) that sets standards for multimedia communications over Local Area Networks (LANs) that do not provide a guaranteed Quality of Service (QoS). These networks dominate today’s corporate desktops and include packet-switched TCP/IP and IPX over Ethernet, Fast Ethernet and Token Ring network technologies. Therefore, the H.323 standards are important building blocks for a broad new range of collaborative, LAN-based applications for multimedia communications. It includes parts of H.225.0 - RAS, Q.931, H.245 RTP/RTCP and audio/video codecs, such as the audio codecs(G.711, G.723.1, G.728, etc.) and video codecs (H.261, H.263) that compress and decompress media streams.

该H.323的标准提供了一个基础，音频，视频和数据通信跨越基于IP的网络，包括互联网。 H.323协议是一个伞式的建议，由国际电讯联盟（ ITU ）的设置标准，多媒体通信局域网（局域网）不提供保证服务质量（ QoS ） 。这些网络的主宰今天的企业台式机和包括分组交换的TCP / IP和IPX以太网，快速以太网和令牌环网的网络技术。因此， H.323的标准是重要的积木一个新的广阔范围内的合作，基于局域网的应用为多媒体通信。它包括部分h.225.0 -r as基因， q .931， h .245R TP/ R TCP的和音频/视频编解码器，如音频编解码器（ g .711，语音编解码， g .728等）和视频编解码器（ h.261 ， H.263编码）压缩解压缩媒体流
