- I don't know whether this comes under your category of "technical capabilities",
- but it seems to me a very important issue is the availability of an overall
- architecture which allows easy interoperability between a wide selection of
- plug-in hardware and software. This allows you to tailor the cost and features
- of the system to suit your needs: like using hardware-assisted compression
- on the authoring machine, without this being a necessity on the delivery
- machine. It also eases the incorporation of multimedia features into more
- "mainstream" applications, such as databases and e-mail.

- I would say further that "Interactive Multimedia" is splitting into two
- distinct varieties: the "traditional" variety, involving reliance on external
- hardware like laserdisc players and the like in the delivery platform, and
- (for want of a better term) the "desktop digital video" variety, exemplified
- by QuickTime and Video for Windows.
-
- The "traditional" variety, it seems to me, uses the computer as little more
- than a control centre, sending commands to the external hardware telling it
- to start and stop and so on. "Desktop digital video", on the other hand,
- involves storing the data (and not just video) in computer-accessible digital
- form, and playing it back from there. Both kinds let you be interactive, but it
- seems to me the latter form offers new opportunities for interaction, because
- you can do all kinds of manipulations of the stored data that aren't otherwise
- possible--create your own presentations, in other words.
