1. Introduction

   The document registers the H224 media type, which may be used by
   systems that use SDP [RFC4566].

   This media type is used for supporting the simple far-end camera
   control protocol on SDP-based systems.  The media type helps
   signaling gateways between H.323 [ITU.H323] and SDP-based systems to
   use far-end camera control, end to end, without any protocol
   translation in the middle.

   The document defines the H224 media type since the RTP packets in
   H.323 annex Q [ITU.H323] carry H.224 frames [ITU.H224].  The far-end
   camera control protocol (FECC) is internal to the H.224 frame and is
   identified by the client ID field of the H.224 packet.

   The document will define the SDP [RFC4566] parameters needed to
   support the above far-end camera control protocol in systems that use
   SDP.
