A new version of the modality grouping draft is available. The main differences are corrections of minor spelling mistakes, and restructuring a couple of complex sentences for improved readability. There are two topics covered. They can be seen as free-standing extensions of what has been discussed for draft-ietf-slim-negotiating-human-language. 1. The need to get (or produce) the same human language contents in two or more modalities approximately simultaneously. E.g. spoken and written. One of these modalities would then be an automatic or human generated transform of the other. Earlier specified mechanisms for language selections do not have any difference between indicating language in two modalities as alternatives to select from versus a preference to use both simultaneously. Applications are e.g. for a user with limited hearing or in noisy environment who needs to combine hearing with the option of reading the same contents when hearing fails. 2. The need to describe preference level between alternative modalities so that the commonly most preferred language and modality for communication can be selected. Thereby communication can start smoothly and disconnection or inclusion of non-needed interpretation avoided. Examples: a) prefer to receive text but can accept to receive spoken language. b) prefer to send sign language but can accept to send text. Known shortcomings: 1. This draft has the same shortcoming as has been discussed lately for draft-ietf-slim-negotiating-human-language in that it cannot distinguish between spoken and written language in other than audio and text media. Only sign languages have distinguishable language tags. That is a separate problem. 2. This draft cannot specify that two modalities using the same media stream are wanted simultaneously. (E.g. subtitling in the video stream of a speaker seen in the same video stream. ) This is partly depending on shortcoming 1. Comments are welcome Gunnar -----------Forwarded message------------------------ A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Human Language Modality Grouping Semantics in Session Description Protocol Author : Gunnar Hellstrom Filename : draft-hellstrom-slim-modality-grouping-01.txt Pages : 11 Date : 2018-01-03 Abstract: When setting up a real-time communication session, there may be a need to indicate preference for which media and modality (spoken, written or signed) to use for language communications or a need to indicate preference for receiving the same language content simultaneously in two modalities. This document defines the semantics for grouping media for such purposes in the Session Description Protocol (SDP). The semantics defined in this document are based on the SDP Grouping Framework. Applications are for example negotiation the most suitable common modality or modalities for language communications in a real-time session. The indications are specified for the sending and receiving direction separately.
