I always assumed DVI was a particular compression technology developed 
by RCA (being the first technology that could play FMV from input at   
CD-ROM speeds) then bought by Intel, who put a couple of chips on a 
board to implement this algorithm. Then I read

"DVI processing" "doing real time MPEG decompression"??? What exactly does
this mean? Is DVI now just another name for the ActionMedia II boards, or
is it some code name for "IBM/Intel's strategic multimedia hardware"?
Please help...

I'll take a stab at this, and others can correct me later.

You are right in that "DVI" is a label for a particular compression
technology, developed at the Sarnoff lab I believe.  Intel has put that
technology on a chip, the current version called the i750.  Intel and
IBM have mounted that chip on a board set for the PC called
"ActionMedia II".

So, "DVI" is really a label for the technology.  However, it often used
loosely to describe the chip and the boards as well.

The fuss is that Intel was supposed to be working on a new,
super-duper, chip for the next generation of boards, and the plans seem
to have changed.

To end, let me plug my mailing list again:

There is a mailing list for discussions about DVI technology in
general, and ActionMedia in particular.  There is also an associated
anonymous FTP archive site for programs and information from Intel and
other places.
