Re: [AVT] I-D ACTION:draft-ietf-avt-rtcpssm-03.txt
Dear Art;
There is a working group for no-return path transport, UDLR
http://www.ietf.org/html.charters/udlr-charter.html
which includes multicast. How do these approaches compare ? How
different is the ATSC work from the DVB standards ? There was I think
a ip-dvb BOF in Atlanta, but I do not know if this will become a
working group.
Regards
Marshall Eubanks

address the problem of multicast when no return path is available. See

A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Audio/Video Transport Working Group of
the
IETF.
Title : RTCP Extensions for Single-Source Multicast
Sessions
with Unicase Feedback
Author(s) : J. Chesterfield, E. Schooler, J. Ott
Filename : draft-ietf-avt-rtcpssm-03.txt
Pages : 37
Date : 2003-3-5
This document specifies a modification to the Real-time Transport
Control Protocol (RTCP) to use unicast feedback. The proposed
extension is useful for single source multicast sessions such as
Source Specific Multicast (SSM) communication where the traditional
model of many-to-many group communication is either not possible or
not preferred. In addition, it can be applied to any group that
might benefit from a sender controlled summarised reporting
mechanism.

Internet-Drafts are also available by anonymous FTP. Login with the
username
"anonymous" and a password of your e-mail address. After logging in,
type "cd internet-drafts" and then
"get draft-ietf-avt-rtcpssm-03.txt".
A list of Internet-Drafts directories can be found in
http://www.ietf.org/shadow.html
or ftp://ftp.ietf.org/ietf/1shadow-sites.txt
Internet-Drafts can also be obtained by e-mail.
Send a message to:
mailserv@ietf.org.
In the body type:
"FILE /internet-drafts/draft-ietf-avt-rtcpssm-03.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
