- real time streaming protocol — (multimedia, networking, protocol) (RTSP) An application layer protocol for controlling delivery of a stream of real-time multimedia content. RTSP allows users to start playing from a certain position. It does not actually deliver the data, but works alongside existing delivery channels such as UDP, TCP, or IP multicast. RTSP was developed by RealNetworks, Netscape Communications, and Columbia University, and is described in RFC 2326, April 1998. RTSP is an IETF proposed standard.
- real-time transport protocol — (protocol) (RTP) An Internet protocol for transmitting real-time data such as audio and video. RTP itself does not guarantee real-time delivery of data, but it does provide mechanisms for the sending and receiving applications to support streaming data. Typically, RTP runs on top of the UDP protocol, although the specification is general enough to support other transport protocols. RTP has received wide industry support. Netscape intends to base its LiveMedia technology on RTP, and Microsoft claims that its NetMeeting product supports RTP.
