| IP网络上的实时视频和音频传输系统 |
ITU-T J.388建议书定义了用于经IP网络实时视频/音频传输的系统。系统协议包括会议控制和媒体传输。会议控制以会议发起协议（SIP）为基础，而本建议书针对SIP的使用引证了ITU-T J.366.4建议书。为媒体传输确定了多种类型的分组格式。本建议书提供了一些强制性调制解调器和一些可选调制解调器。配备这里介绍的协议的系统，可用于可视电话等双向应用，也可用于视频新闻采集等单向应用。即使在进行视频新闻采集时，通常也需要在现场记者和制作间之间进行双向通信传输。此外，由于在定义系统时考虑到了实施的复杂性，故提供了基于软件的嵌入性解决方案，从而降低了成本需求并较硬件解决方案缩短了研发周期。 |
