Voila!  I found a little more detail on what info goes onto a CD-XX disc.
CD-V (CD-Video) 20 minustes of music PLUS 5 minutes of video with sound; the
video is not full motion AT THIS TIME, because the CD specs can't handle the
bandwidth.

CD-I (CD-Interactive) a Sony-Philips development, using High Sierra encoding
enhanced for more detail.  Uses a special decoder based on Motorolas 68000 chip
(to have been completed by this Fall).  Currently, offers 128 color
10-frames/second video - that decoder will change this.

Sony, Philips and Matsushita have licensed developer kits and hardware tools
out in industry.  these tools include run-time, source conversion,
disc-building.  The hardware consisted of a simulator to allow program testing
on existing CD players.

Price on this wonder was to be in the $500-1,000 range; my bet is more like
$1,500 (all in US dollars - I am posting from Canada, home of the $0.85 dollar
this morning).

CD-XA (CD-eXtended Architecture) is an upgrade to CD-ROM.  It incorporates CD-I
enhanced graphics and audio capabilities to existing players, via a chip
upgrade.  (650 Megabyte= 16 hours audio in mono at a quality comparable to AM
radio -- WOW! Won't Elvis fans be pleased?)

DVI (Digital Video Interactive) offers full-motion interactive video using
highly compressed images, and may de-rail CD-I development.  Using SCSI at 12.5
megabytes per second, using the standard CD-ROM form factor (Hey! That means
its the same size!  Why didn't you say that?  Cause no-one else says that.
OH!) with 650 Megabytes of storage, you can expect 72 minutes of full-motion
video.

As an aside, a study in 1988 by Business Communications Co., indicated that by
1993, the market would be split as follows:
videodisc players: 17.1% (such accuracy)

CD-ROM: 40.1%

CD-Video (CD-I and DVI): 33.5%
This is for industry growth figures in business use.  Any ideas if these
figures have changed in two years?
