RE: multimedia definition

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.
