Appendix A. Draft History

01: removed "stage direction" in "left" "right". Replaced with "to be interpreted in context".

clarified "local" to mean "in the same room" per J. Polk email 6/14/11

Consistently refer to "loudspeaker" per Christer's email 6/13/11

Added "keyboard" to listed caputure devices per Christer's email 6/13/11

Rendering device: changed "optical" to "visual". Hope Christer finds this OK. Per Christer's email 6/13/11

Note: the other changes proposed by Christer in his 6/13 email appear to change more than just words but semantics. Not included here as such semantic changes are best handled in the requirement and other docs.

Edt. Note: there have been lengthily discussions about the term "Participant". One camp wanted the word to refer to human users of telepresence equipment so to use intuitive language, the other (as this document) suggests to use the word in the RFC

Participant defined as per RFC 4353. I think this is what we arrived at on the mailing list, right?

Added "Telepresence Extensions" per long "solutions" thread.

00: Initial version; mostly copy-past from requirements-02.

Removed "session". Editors are advised to be specific about SIP, RTP, or whatever else sessions.

Made clear that Layout refers to rendering, not capturing.

added Left, Right, in stage direction, w/ Wikipedia reference
