Title:		 Multicast Acquisition Report Block Type for RTP Control Protocol (RTCP) Extended Reports (XRs)
Creation_date:	 2011-03-30
WG ID:		 avtext
Number_of_pages: 21

Abstract:
In most RTP-based multicast applications, the RTP source sends inter-
related data.  Due to this interdependency, randomly joining RTP
receivers usually cannot start consuming the multicast data right
after they join the session.  Thus, they often experience a random
acquisition delay.  An RTP receiver may use one ore more different
approaches to achieve rapid acquisition.  Yet, due to various
factors, performance of the rapid acquisition methods usually varies.
Furthermore, in some cases the RTP receiver may (or may have to) do a
simple multicast join.  For quality reporting, monitoring and
diagnostics purposes, it is important to collect detailed information
from the RTP receivers about their acquisition and presentation
experiences.  This document addresses this issue by defining a new
report block type, called Multicast Acquisition (MA) Report Block,
within the framework of RTP Control Protocol (RTCP) Extended Reports
(XR) (RFC 3611).  This document also defines the necessary signaling
of the new MA report block type in the Session Description Protocol
(SDP).
