[SIPForum-discussion] RTP media flow: voice&video

[Gunnar Hellstrom]

There is at least one more medium that make use of RTP. That is real-time
text for conversational purposes. Its RTP payload is defined in RFC 4103.
The data is Unicode UTF-8 coded text according to ITU-T T.140 transmitted
time-sampled in 300 ms samples. 

It is intended to be included in multimedia calls, preferrably together with
video and audio, to form Total Conversation or Multimedia Telephony. 

It is declared in sdp as text/t140 and text/red

Other data RTP packetisations are e.g. timed text, and I think also remote
device control is ready.

Hi,

Can anyone tell me if a RTP media flow can be video, voice and data or only
video and voice can be transported over RTP?

Thanks in advance for your help,
Best Regards,
Mario
