actually its a lot smaller than that about 2 meg. Like a sunray it
can tftp its firmware image and stream straight from mythtv
the sunray also requires server software so saying that its different
because it requires some server software is a non sequitur
the point was that its a network device that can play video fine but
the sunray can't

And there's no software managing the Happauge right? No OS needed
at all? You can put it in a PC with no hard drive and it will
work? Oh wait...12 Mb exectuable the exacts to how big? Requires
how much software (dll's and such) from Windows?

what's your full screen? 640x480 or 1920x1200? Huge
difference in the
amount of horsepower required to shoot those pixels down the
screen.
Understood, but Assume each SunRay has a 100Mb/s link to a
dedicated switch
port, With a big enough server farm paid for by all my TCO savings,
shouldn't it work?
Hmmm - let's see.
30 frames/sec * (1920 * 1200) pixels/frame * 24 bits/pixel = 1.7
Gb/s [1]!
It's even overwhelming for 100Mb/s ethernet at 640x480 (210 Mb/s)
i really dont see why this is so hard ...
a £35 mvp from hauppauge can play streams over ethernet
http://www.hauppauge.com/html/mediamvp_datasheet.htm
and this is just one of many, media players that play network streams
it would have just needed an mpeg decoder chip in the sunray and
way of sending/controlling the streams
I guess not...
Full motion, full screen video is going to require compression
which means codecs on the client. The question always becomes
"which codecs do you choose?" since the media world has so many
"standards", and getting onto the codec treadmill is an enormous
committment of resources (the army of lawyers marching in this
space doesn't help either).
OTOH, most of the applications people describe for video on the
desktop don't seem to require full motion, full screen resolution.
Certainly not conferencing, or corporate communications. Maybe
training videos.

[1] By the way, this is absurdly high resolution for video, not
even HDTV
has a resolution this high (720p60: 1280x720 1080i50: 1920x1080),
let
alone PAL (square pix: 768x576) or NTSC (square pix: 720x540).
