Ballot Text

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
draft-ietf-avt-rtp-hdrext 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 through Working Group Last Call. There is a
strong Working Group consensus in favour of the present document. 

Document Quality 

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

Personnel 

Tom Taylor is the Document Shepherd for this document.
