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 can use one or more different approaches to achieve rapid acquisition. Yet, due to various factors, performance of the rapid acquisition methods usually varies. @@ -36,21 +36,21 @@ Internet-Drafts are working documents of the Internet Engineering Task Force (IETF).

Introduction RTP Control Protocol (RTCP) is the out-of-band control protocol for the applications that are using the Real-time Transport Protocol (RTP) for media transport [RFC3550]. In addition to providing minimal control functionality to RTP entities, RTCP also enables a basic level monitoring of RTP sessions via sender and receiver reports. More statistically detailed monitoring as well as application-specific monitoring is usually achieved through the RTCP @@ -657,54 +657,38 @@ Requirement Levels", BCP 14, RFC 2119, March 1997.
