 IANA registrations of SDP 'proto' attribute for transporting RTP Media
                  over TCP under various RTP profiles.

Abstract

   The Real-time Transport Protocol (RTP) specification establishes a
   registry of profile names for use by higher-level control protocols,
   such as the Session Description Protocol (SDP), to refer to the
   transport methods.  This specification describes the following new
   SDP transport protocol identifiers for transporting RTP Media over
   TCP: 'TCP/RTP/AVPF', 'TCP/RTP/SAVP', 'TCP/RTP/SAVPF', 'TCP/DTLS/RTP/
   SAVP', 'TCP/DTLS/RTP/SAVPF', 'TCP/TLS/RTP/AVP', 'TCP/TLS/RTP/AVPF'.

1.  Overview

   RTP provides end-to-end network transport functions suitable for
   applications transmitting real-time data such as audio, video or
   simulation data, over multicast or unicast network services.  The
   data transport is augmented by RTP Control Protocol (RTCP), to allow
   monitoring of the data delivery in a manner scalable to large
   multicast networks, and to provide minimal control and identification
   functionality.

   SDP [RFC4566] provides a general-purpose format for describing
   multimedia sessions in announcements or invitations.  [RFC4145]
   specifies a general mechanism for describing media transport over
   Transmission Control Protocol (TCP) using SDP with [RFC4571] defining
   a method for framing RTP and RTCP packets [RFC3550] onto a
   connection-oriented transport (such as TCP).  [RFC4572] extends
   [RFC4145] for describing TCP-based media streams that are protected
   using Transport Layer Security (TLS) [RFC5246].

   This specification describes additional SDP transport protocol
   identifiers for transporting RTP Media over TCP as defined in
   Section 3.
