OK, but I don't agree with your example. I'd argue that with either definition that the page with links and background audio is multimedia. Only the author can verify whether the audio is synchronized or not, so this may not be very testable. The page might be low-tech multimedia, but it should be evaluated by an author to determine whether captions or descriptions are needed because of the audio.

But the word "Synchronized" is important or else a page with links (interaction) combined with an audio playing in the background would be multimedia - and that is not our intent. It is only if the audio is synchronized with the interaction (the interaction has to take place at a certain time in the audio presentation) that it qualifies. Ditto with audio and graphics unless the graphic presentation is synchronized with the audio. So incorporating your 'and/or" edit we end up with Multimedia: Content that includes one type of time dependent media (e.g. audio or video) synchronized with interactive elements and/or with another type of media (e.g. text, audio, graphics, or video) Gregg -- ------------------------------ Gregg C Vanderheiden Ph.D. Professor - Ind.

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). awk ________________________________ From: w3c-wai-gl-request@w3.org [mailto:w3c-wai-gl-request@w3.org] On Behalf Of John M Slatin Sent: Tuesday, December 13, 2005 7:05 PM To: John M Slatin; Gregg Vanderheiden; w3c-wai-gl@w3.org Subject: RE: multimedia definition 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> John "Good design is accessible design." Dr. John M.

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> John "Good design is accessible design." Dr. John M.

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 -- ------------------------------ Gregg C Vanderheiden Ph.D. Professor - Ind.

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
