> Technical Summary
> 
> The Session Description Protocol (SDP) has an attribute that allows RTP
> applications to specify an address and a port associated with the RTP
> Control Protocol (RTCP) traffic.  In RTP-based source-specific
> multicast (SSM) sessions, the same attribute is used to designate the
> address and the RTCP port of the Feedback Target in the SDP description. 
> However, the RTCP port associated with the SSM session itself cannot be
> specified by the same attribute to avoid ambiguity, and thus, is
> required to be derived from the "m=" line of the media description. 
> Deriving the RTCP port from the "m=" line imposes an unnecessary
> restriction.  This document removes this restriction by introducing a
> new SDP attribute.
