Title : RTP Payload Format for 3GPP Timed Text
Author(s) : J. Rey, Y. Matsui
Filename : draft-ietf-avt-rtp-3gpp-timed-text-05.txt
Pages : 43
Date : 2004-8-18
This document specifies an RTP payload format for the transmission of
3GPP (3rd Generation Partnership Project) timed text. 3GPP timed
text is a time-lined decorated text media format with defined storage
in a 3GP file. Timed Text can be synchronised with audio/video
contents. As of today, 3GP files containing timed text contents can
only be downloaded via HTTP. There is no available mechanism for
streaming 3GPP timed text contents neither out of 3GP files nor
directly from live content. In the following sections the problems
of streaming timed text are addressed and a payload format for
streaming 3GPP timed text over RTP is specified.

In the body type:
"FILE /internet-drafts/draft-ietf-avt-rtp-3gpp-timed-text-05.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.
