RE: : multimedia - Synchronized Media

Actually not quite right.

 

Synchronized media includes   a single media type synchronized with
interaction. 

 

So it isn't just multiple media types that are synchronized. 

 

In fact it may be just one media type.

True, one media type in the set leaves nothing else to coordinate with. Of
course it depends a bit on what was mean by synchronized. You could just
have audio with timeline based controls to keep the playback in sync with
the time selected. Is a single media set a case we should be concerned with?

Synchronized Media


A set of media types, required for understanding or use of the complete
presentation, coordinated to a common timeline.




Note: The set of media types does not include equivalents such as captions,
subtitles, or video description.

I actually quite like that. It seems elegant to me.

Are audio and video the only types? What if I have just a slide show? What
about some data visualization widgets? In other words, with only slight
changes could the section be generalized to cover future cases?

--------
Synchronized Media
A set of one or more media types which are synchronized to a common timeline
such that interaction is coordinated between the members.
--------

Or is the scope of work purposely specific to just cover audio/video?

Andrew, I agree that we need the equivalents that you mention. The problem I
have is with the wording of the sentence not with what we are trying to say.
It seems like we are saying 

Audio with time-based interactive OR

Video with time-based interactive

It needs to be clear that it also means:

Video with Audio 

Perhaps we are saying that time based interactive includes audio or video
but I don't think this is clear. Perhaps something like this.

Synchronized Media 

Audio with corresponding video displayed at the same time. 2) Audio or video
displayed at the same time as other time-based content and/or with
time-based interactive component that is required for understanding or use
of the complete presentation. 

Note: The "other time-based content" that the audio or video is synchronized
with to meet this definition does not include equivalents such as captions,
subtitles, or video description.

I disagree with that assessment.  Synchronized media  can be lots of things.
audio slide shows, audio with interactivity are also very common.  I don't
think that it is misleading - it is important since these are the key items
that require the equivalents that aren't required elsewhere.

The only thing that bothers me about it is the opening.

"Audio or video."  Most synchronized media (multimedia), I'd say 95%,  is
Audio synchronized WITH video. So placing the two of them at the front of
the sentence with an OR separating them is kind of misleading I'd say.
