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

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,

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.
/me orders one bag of magic pixie dust from Ebay

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
