I've been thinking about this one. At first it seemed like having a
lossless compression would provide a great solution that could be used
for anything (video, CAD, games, ...). But it has some disadvantages.
We'd have to decode in the host computer, then reencode in the
DisplayLink's lossless codec. So it is less efficient. Then I
thought, why couldn't we use one of the video decoder chips in the
Ethervideo box, and have the host computer encode CAD/game/whatever
output into mpeg?
I don't think so. Yes, we could use system end compression to transmit
images to the board, but we probably couldn't compress the graphics
instruction stream with MPEG*, but I don't think that it would need
compression for that. That is, IIUC, the hardware video acceleration is
going to be in the box and unlike some video boards, it is going to have
to be self contained -- not send a lot of data to and from system memory
on the host system.
