   SDP and RTSP Extensions Defined for 3GPP Packet-Switched Streaming
           Service and Multimedia Broadcast/Multicast Service

Abstract

   The Packet-switched Streaming Service (PSS) and the Multimedia
   Broadcast/Multicast Service (MBMS) defined by 3GPP use the Session
   Description Protocol (SDP) and Real Time Streaming Protocol (RTSP)
   with some extensions.  This document provides information about these
   extensions and registers the RTSP and SDP extensions with IANA.
