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.
