Audio and video streams are preferably transmitted through the User Datagram Protocol ( UDP ). 音频和视频流通过用户数据报协议(UserDatagramProtocol,UDP)传输较为可取。
In order to implement real-time video querying in an Ethernet digital video monitoring system based on H.263 protocol, a set of data-packet format was designed based on UDP ( User Datagram Protocol ), which assures the reliability of the system. 在一种基于H.263协议的以太网数字视频监控系统中,为实现实时视频查询,设计了一套基于用户数据报协议的数据包格式,保证了上层应用程序的可靠性。
