The IESG has received a request from the Audio/Video Transport Core Maintenance WG (avtcore) to consider the following document: - 'RTP-mixer formatting of multi-party Real-time text' <draft-ietf-avtcore-multi-party-rtt-mix-14.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2021-05-03. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Enhancements for RFC 4103 real-time text mixing are provided in this document, suitable for a centralized conference model that enables source identification and rapidly interleaved transmission of text from different sources. The intended use is for real-time text mixers and participant endpoints capable of providing an efficient presentation or other treatment of a multi-party real-time text session. The specified mechanism builds on the standard use of the CSRC list in the RTP packet for source identification. The method makes use of the same "text/t140" and "text/red" formats as for two- party sessions. Solutions using multiple RTP streams in the same RTP session are briefly mentioned, as they could have some benefits over the RTP- mixer model. The possibility to implement the solution in a wide range of existing RTP implementations made the RTP-mixer model be selected to be fully specified in this document. A capability exchange is specified so that it can be verified that a mixer and a participant can handle the multi-party coded real-time text stream using the RTP-mixer method. The capability is indicated by use of an SDP media attribute "rtt-mixer". The document updates RFC 4103 "RTP Payload for Text Conversation". A specification of how a mixer can format text for the case when the endpoint is not multi-party aware is also provided. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-avtcore-multi-party-rtt-mix/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list [email protected] https://www.ietf.org/mailman/listinfo/ietf-announce
