RDT stream transport

From Wikipedia, the free encyclopedia

RDT (Real Data Transport) is a proprietary transport protocol for the actual audio/video data, developed by RealNetworks in the 1990s. Commonly used in companion with a control protocol for streaming media like the IETF's based RTSP protocol. An alternative IETF's based transport protocol is RTP, fully implemented, like RTSP, in RealNetworks players.

RDT is now included as part of the Helix Community project.
