Remember, in my case we had a limited channel, so the idea wass to
inform adequately and as fast as the channel permits.
It was not a modern almost-unlimited uinlimite-speed system, but in
fact a telephone line system, in the late sixties, over a 1 million
square kilometre area of oilfilds.

The idea was to have person-to-person communication over a phone line,
with computer screens in the link, with more than one person working
on a common document (presentation for discussion) and signalling with
individual "mouses" (colour coded). It worked. The digital part
occupied part of the bandwidth, the voices the other part. The picture
refresh at the opposite end was the hard part, but we subtracted
images (before and after) and sent the difference as an update. Since
the mouses used different colours we only sent that one, which helped.

I also used similar codings in a technique for a person to sign a
pad, move the encoded signature to a central office and authotise or
not that signature (by personal check against digitised speciman on
same screen)..
Ah! Those were golden days...

I implemented that many years ago in a 3d engine of mine. Made a
showcase for Maxim's algorithm and accidentally coined the term. :)

Think about this.
You take a picture of pixels (say 2^n square to be simple to
describe).
You "compress" it this way
Divide into new pixels of 4 by 4 and average the individual RGB
colours and make a new 2^n-1 square and store it.
Repeat till there is only one square.

Now you transmit the frames in reverse, but add coding to refer only
to changes to the previous average colour if a change is required,
else skip sub-pixel modification. This isn't by any means a
compression, but is a way of providing more and more information as
time goes by. This is what I was trying to explain about the use of a
slow channel to a human, when the computing is sufficiently fast. The
information content at the human end improves with time. It helps
comprehension before the picture is finished.
