Re: [MMUSIC] draft-gellens-mmusic-negotiating-human-langua
Hi Gunnar,

Thanks again for the quick review and comments.

I agree it can be helpful to include a clarifying note that a spoken language can be used with a video stream to indicate a request to see the speaker.  I'm not sure that normative language is needed here but I have added informative text to both 7.1 and 7.4 (on silly states).

At 2:08 PM +0200 7/8/13, Gunnar Hellstrom wrote:

There is a good description of avoidance of using subtags in 7.1, third paragraph from the end.

It may be good to inform after that paragraph about the language tags that can be used for video.
There are separate language tags for sign languages.
So, for the video medium, that can be used to distinguish between two different usages of video; for sign language versus for assisting hearing with the view of the speaking human for lip-reading or for just emphasizing the understanding by a view of the speaker.

Insert a new paragraph to be the third from the end of 7.1:

For indication of preferences and capabilities of sign languages, the specific sign language tags of RFC 5646 SHALL be used in the video media specifications.
Preference and capability of a spoken language tag (i.e. not a sign language) indicated in the video media specification SHOULD be used for indicating a view of the speaking human that may be needed or preferred for speech-reading assisted hearing.
