I think controlling the content is the missing piece of the puzzle. You
could do this with television/DVD/etc (at least "play / don't play) it
wouldn't really work with web based content.

I've dug the info up -
From a colleague's recent email -
'A lot of customers say "We want to watch TV
(like CNN or other news channels) on the Sun Ray. Is this possible?". I
guess you now the answer: YES! Not via the sun ray server but with some
special displays having a Picture-in-Picture feature. There are some
available from EIZO, Samsung, etc (just google around). These displays
can show tv in a small box over the video signal of the sun ray.'

Chris,
I would be very ionterested in this option - do you have any details?

You can stay on that soap box as long as you like Dave, if those are
the comments you want to make :)
Some customers with heavy TV style requirements are currently
trialling Sun Ray with LCD screens that take in a TV feed separately
from the computer feed. I can't remember off the top of my head what
that feature is called, but it works well - 'computer' stuff fills
the screen and is all thin client friendly. TV feeds such as
Bloombeg and CNN sit in a separate window in the LCD screen and don't
impact the thin client setup's bandwidth or performance - best of
both worlds.
I know this isn't practical for every customer environment and it
would be great if Sun Ray did everything a PC can do *and* was a zero
admin device, but sometimes you need a bit of creative thinking.

(Start soapbox)
I Have close to 1400 Sun Ray DTU's in operation. We have tested
video on
everything from E420R's to SF4800 systems. The bottom line is that the
Sun Ray
is the best "time share" device on the planet. To define "time share",
if you
have a 100 users, only 10-20% normally are using their desktop at any
given
instance. The other 80-90% are reading a web page,typing an e-mail, or
talking
to there cube mate. 100 users watching a video streaming of cnn.com
does not
fall into the "time share" model. Video would work if the users dont
mind a 2
inch screen, but that is not practical. There are methods to watch cnn
with
streaming video, the best method it to buy a TV. A Ultra 20 desktop
with a
Dual Core Opteron with 2GB of RAM streams video quite well, however our
company policy forbids all streaming audio and video. Bandwidth is
simply to
valuable to waste. I do agree that this would be a great future
upgrade for
the DTU's, but Im a SPARC loyalist where the real "Heavy Iron Exist". A
nd!
if you want the best reason as to why the Sun Ray is the best time
share
device, we manage the 1400 Sun Rays (With Solaris and Windows Remote
Desktops)
with 2 administrators. Try that for TCO. (Sorry, end soapbox)

Subject: Re: [SunRay-Users] My results with video on SunRay
Not trying to flame just educate. Conversation is always good.
What I would ask is how does one manage thousands of those devices
that "boots a Linux 2.6.12 kernel". Sun Rays take a different
approach. Zero admin of the desktop, and 100 percent server based
computing. Somethings, such as video, are just not going to work as
well. Not to say we're not investigating how to make it better.

I'm not sure about a 100Mhz PC but its running on these 200Mhz
units - but whether that includes video I'm not sure
http://linuxdevices.com/articles/AT7499590573.html
As for the details this article explains the approach to X
compression
http://www.nomachine.com/documentation/html/NX-XProtocolCompression.html
Again, I realise I could be getting close to being flamed for
suggesting something that I don't know a great deal about but I
thought it worth pointing out in case the Sun engineers are
looking for ways to reduce X traffic and had perhaps not heard of
the techniques used by this company
Craig Bender wrote:
Exactly. The Sun Ray only has a 100 Mhz processor. Find a 100
Mhz PC and try to 1) load and OS on it and they try to run
NoMachine on it.

Perhaps it should be renamed to "OneMachine"?

How much of an OS do you need to use Nomachine?

I know I've mentioned this product before but the video output
on NoMachine NX (http://www.nomachine.com) is very good. I'm
not sure of the scale of rework involved (or any other
compatibility issues for that matter) but I would guess the
same thin client compression technology on Sun Rays could
maybe solve a lot of these bandwidth problems

Video is not a wonderful user experience on any true thin
client I've tried recently. Anyone who's rendering all their
video on the server is going to run into issues. Full screen
video simply isn't Sun Ray's target market.
What Sun did with Sun Forum, as I understand it, was to make
it work better with Sun Ray by having it bypass the X Server
and talk directly over the wire to the DTUs.
Craig Bender can probably provide a bit more technical detail!

To summerise:
Video is crap on Sunrays...
So, how did Sun make it work with their video conferencing
tools? Does anybody have any results using this?
Thanks,

pink came out as blue (so people look a little odd)

I have tried VLC and Realplayer, they both work ok with
very small video windows (i.e. scaled down) but anything
larger just sucks. It'd be cool if there was some magic
that detected video and did something even more magic to
make it just work nicely. That way you;d not need a
special video player to play video to a SunRay, it'd just
know that this screen area was rapidly changing, assume
video and the rest would be magic.

Hi,
I have been playing with video on SunRays over the
weekend.
Server is a MSI K8 Neo2 FIR MOBO with a 4800+
dualcore 2.4 GHZ Athlon64 cpu
and 1 GB RAM.
Solaris 10u1 with SRSS 3.1 is installed.
Companion CD is installed.
I downloaded the Mplayer 1.07try2 source and built it
with
/usr/sfw/bin/gcc -mtune=k8 -march=k8
Downloaded a bunch of codecs and built it so it
Mplayer can play
MPEG , Windows Media, Real media and LIVE streams.
Downloaded the MplayerPlugin for mozilla and friends
and Gmaked it.
Also compiled in Xvideo support to run on the Nvidia
VGA screen.
Doesnt run on sunrays though. Xvideo in fullscreen mode
on the
Geforce6800 is cool ;- )
Of the output formats that Mplayer supplies it seems
that SDL is the only one
that runs on SunRay. Xv, x11 ,or openGL does not work
for me.
After deployment of the MplayerPlugin I can play
video-on demand streams from
cnn.com and cmt.com on the sunray. both of these
are in Windows Media Format.
This would not work on a SPARC platform I suppose because
of the X86 codecs.
When I play a video stream from www.cmt.com I seem to
use about a fifth of a CPU.
so theoretical maximum on this PC server would be 10
concurrent sunrays using video.
This should translate to 15 -18 concurrent videos
streams on a X4200
I begin to see why people on this list are moaning
about video performance :-)
How does this result compare to yours ?
Regards
Lars Tunkrans
