What do you mean by interoperability here? And why is this an issue? the world is full of non interoperable systems, Flash, HTML, Java, SMIL, blah blah blah.

If an agency picked VHS then they couldn't play it back on computers or DVD players. If they picked Flash to publish a multimedia course then they couldn't use a Java player to view it.

If an agency wants to do electronic distribution, they would need to procure a complete system. If for example the agency chose to use windows media for something, then they would need to acquire tools that can generate, caption, and stream it, and players to view it. There exists many tools for importing and exporting various media formats if that is an issue.

I don't see any new problem here which isn't true of all E&IT.

Thanks

Couple questions about the part where you changed it to
"Uses this standard...
Captions or timed text (as defined by procuring agency) or display open caption video"


- How would you get interoperability if each agency picks its own standards?
- Will purchasing agents have any idea what to specify?
- And how would a mfgr know how to design products if they don't know what standard will apply until the get the P.O.?

Maybe I'm missing something

Thanks
