The IESG has approved the following document: - 'RTP Payload for Text Conversation ' <draft-ietf-avt-rfc2793bis-09.txt> as a Proposed Standard This document is the product of the Audio/Video Transport Working Group. The IESG contact persons are Allison Mankin and Jon Peterson. Technical Summary This specification describes how to carry real time text conversation session contents in RTP packets. Text conversation session contents are specified in ITU-T Recommendation T.140. One payload format is described for transmitting text on a separate RTP session dedicated for the transmission of text. This RTP payload description also recommends a method to include redundant text from already transmitted packets in order to reduce the risk of text loss caused by packet loss. It uses the payload format format specified in RFC 2198, and updated in draft-ietf-avt-text-red, in current IETF review. The document obsoletes RFC 2793. The text clarifies ambiguities in RFC 2793, improves on the specific implementation requirements learned through development experience, and gives explicit usage examples. Working Group Summary The material in this document was strongly supported by the AVT working group. There has been considerable IETF review of the text/red media type; in this document, the RTP domain usage is clearly indicated, as was carefully discussed as the context for that text mediatype. Protocol Quality The document was reviewed for the IESG by Allison Mankin and the AVT Working Group chairs. RFC Editor Notes Abstract OLD: This memo describes how to carry real time text conversation session contents in RTP packets. Text conversation session contents are specified in ITU-T Recommendation T.140. NEW: This memo obsoletes RFC 2793; it describes how to carry real time text conversation session contents in RTP packets. Text conversation session contents are specified in ITU-T Recommendation T.140. IANA Considerations OLD: This document defines one RTP payload format named "t140" and an associated MIME type "text/t140", to be registered by IANA. NEW: This document updates the RTP payload format named "t140" and the associated MIME type "text/t140", in the IANA RTP and Media Type registries. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/ietf-announce
