suggested change:
 
Content that includes one type of time dependent media (e.g. audio or
video) combined with interactive elements and/or with another type of
media (e.g. text, audio, graphics, or video)
 
"synchronized" seems awkward so I put 'combined' to genericize it one
notch.  I made the 'or' an 'and/or' since both are possible.
 
Other than that it sounds good to me (and these are pretty nit-picky).

	Gregg and I took our discussion off-list for a while and
hammered out a definition of multimedia we think will work:
	 
	<proposed>
	 One type of time dependent media (e.g. audio or video)
synchronized with interaction or with another type of media (e.g. text,
audio, graphics, or video)
	
	</proposed>
	If everyone can live with this, it will replace the current
definition in the Glossary (below):
	 
	<blockquote>
	For the purposes of these guidelines, multimedia refers to
combined audio and video presentations. It also includes audio-only and
video-only presentations
	that include interaction.
	</blockquote>

		Gregg,
		 
		The first phrase in the proposed definition (both yours
and mine) is:
		 
		<q>Several different media,</q>
		 
		So even if people believe that "interactive audio" is
one medium and "audio" is a different medium, we're covered by that
first phrase.
		 
		Here it is again:
		<proposed>
		Several different media, including at least one time
based media type, integrated in a single presentation.  Media may
include text, audio (including interactive
		audio), graphics, and video (including interactive
video).
		
		</proposed>
		 
		Or people might be more comfortable with the following:
		 
		<slightRevision>
		Two or more different media, including at least one time
based media type, integrated in a single presentation.  Media may
include text, audio, including interactive
		audio, graphics, video,and interactive video.
		
		</slightRevision>
		 
		I'd prefer to put interactive audio and interactive
video in parentheses, as in the first version above. But I like starting
with "Two or more different media " since it clearly covers the most
common multimedia format, i.e., video plus a soundtrack ("several"
usually means more than 2 ...). So here's one more try:
		 
		<oneMoreTry>
		Two or more different media, including at least one time
based media type, integrated in a single presentation.  Media may
include text, audio (including interactive
		audio), graphics, and video (including interactive
video).
		
		</oneMoreTry>

			Interesting

			 

			But if interactive audio is media then it isn't
multimedia.    And according to our definition (or what we thought
needed to be covered by multimedia) interactive audio or interactive
video needed to be in there.....

			 

			So we would have to rewrite all our guidelines
to say "Multimedia and media mixed with interaction."    

			Oops that doesn't work.  

			 

			It would have to be  "Multimedia and time based
media mixed with interaction."

			Or 

			"Multimedia and video or audio mixed with
interaction."

			 

			Hmm.   Hard to parse the ands and ors

			 

			I think we need to keep interaction in
multimedia.   

			 

			It goes back to the list form which is a
terrible format for definitions but.... 

			 

			 

			Multimedia

			audio or video synchronized with interactivity
or another media type including text, images, (video), (audio), etc.

			 

			OR 

			 

			Multimedia

			A time based media (such as video or sound)
synchronized with interactivity or another media type including text,
images, video, audio, etc.

			Gregg responded to my proposed rewrite of the
multimedia definition:

			 

			<blockquote>

			Actually the interactivity as a medium came from
Wikipedia.

			 

			I thought that was interesting because it is
necessary as a media for our definition as well.

			 

			Interactive audio for example is considered
multimedia.   And it consists of audio and interaction.

			 

			 

			</blockquote>

			 

			I'd be fine with listing "interactive audio" and
"interactive video" as separate media.

			 

			It makes me nervous to treat Wikopedia as an
authoritative source, precisely because it advertises itself as "the
encyclopedia that can be edited by anyone."

			 

			The Wikopedia definition of "multimedia" links
to an article on "interactivity"
(http://en.wikipedia.org/wiki/Interactivity) which is flagged as needing
work. What's there now does not describe interactivity as a medium.

			 

			So here's a modified version of the rewrite I
proposed:

			<newProposal>

			Several different media, including at least one
time based media type, integrated in a single presentation.  Media may
include text, audio (including interactive audio), graphics, and video
(including interactive video). 

			</newProposal>

			 

			I deleted the third sentence from my previous
proposal since interactivity is now incorporated into the list of media
types.

			 

			I also deleted animation from the list of
multimedia types since our definition of "video" (accepted 8 December)
includes animation. But it wouldn't bother me to include it explicitly
here if people want to do that.

			 

			John
