Hi mmusic and avtcore, I have replaced an old expired draft about real-time text multi-party handling. It touches both transport and negotiation topics, so I am sending this to both mmusic and avtcore, but I hope we can keep the discussion in mmusic. So, please respond with your comments to mmusic. Right now, the draft is a discussion paper. I intend to convert it to a true BCP format after some discussions on the preferences I have proposed. Regards Gunnar Hellström -------- Vidarebefordrat meddelande -------- Ämne: I-D Action: draft-hellstrom-mmusic-multi-party-rtt-00.txt Datum: Thu, 31 Oct 2019 16:33:35 -0700 Från: internet-drafts@ietf.org<mailto:internet-drafts@ietf.org> Svar till: internet-drafts@ietf.org<mailto:internet-drafts@ietf.org> Till: i-d-announce@ietf.org<mailto:i-d-announce@ietf.org> A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Real-time text media handling in multi-party conferences Author : Gunnar Hellstrom Filename : draft-hellstrom-mmusic-multi-party-rtt-00.txt Pages : 36 Date : 2019-10-31 Abstract: This memo specifies methods for Real-Time Text (RTT) media handling in multi-party calls. The main solution is to carry Real-Time text by the RTP protocol in a time-sampled mode according to RFC 4103. The main solution for centralized multi-party handling of real-time text is achieved through a media control unit coordinating multiple RTP text streams into one RTP session. Identification for the streams are provided through the RTCP messages. This mechanism enables the receiving application to present the received real-time text medium in different ways according to user preferences. Some presentation related features are also described explaining suitable variations of transmission and presentation of text. Call control features are described for the SIP environment. A number of alternative methods for providing the multi-party negotiation, transmission and presentation are discussed and a recommendation for the main one is provided. Two alternative methods using a single RTP stream and source identification inline in the text stream are also described, one of them being provided as a lower functionality fallback method for endpoints with no multi-party awareness for RTT. Brief information is also provided for multi-party RTT in the WebRTC environment. EDITOR NOTE: A number of alternatives are specified for discussion. A decision is needed which alternatives are preferred and then how the preferred alternatives shall be emphasized. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-hellstrom-mmusic-multi-party-rtt/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-hellstrom-mmusic-multi-party-rtt-00 https://datatracker.ietf.org/doc/html/draft-hellstrom-mmusic-multi-party-rtt-00 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
