Technical Summary

This document describes a method to inform RTP clients when RTP
packets are transmitted at a time other than their 'nominal'
transmission time. It also provides a mechanism to provide improved
inter-arrival jitter reports from the clients, that take into account
the reported transmission times. 

Working Group Summary

This RTP header extension was first defined within
as an initial application of the RTP header extension mechanism that draft
defines. As a result of WG discussion in July, 2006, it was moved to a 
separate draft. Additional discussion resulted in further changes up
Working Group Last Call. There is a strong Working Group consensus in
of the present document.

Solicited review comments from Qiaobing Xie and Ron Frederick provided a
final polish to the document.
