I know that you say that there is no editing on Channel 9... I do think that we would all forgive you if you were to yank out everything in that video prior to you saying “take two” around 2:25, still quite funny to see though.

Would love to see the code for the display. Scoble can you post a link if and when it becomes available?

Great stuff.

I must say after seeing that video... I’m awed, humbled... and a little afraid.

When I first heard about the displays, I figured they were using something not unlike a Sencore HDTV996A or VP3340 (two products I built), both of which play an MPEG-2 transport stream (not unlike what you would pick up over the air) and either modulates it to an RF channel (exactly like what is broadcast OTA in the US) or decodes it and provides an HD DVI or RGB output.

These things are often used for in store advertising and information as well as pre film advertising at movie theaters... Everything that they put out is pre-recorded and schedulable... and seeing the level of detail and dynamic display is... mind boggling and makes me wonder just how far people are going to want to take displays like those shown here and how soon my bosses or one of our customers is going to want something like that built.

Amazing application, I truly am in awe. I can't believe that no one else mentioned this while the PDC was going on! I'd love to see this thing in action.. any possibility of the code being released for this, or is it a personal project that the authors would like to keep under wraps?

I'm peticularly interested in how they went about changing the level of detail for the expanded and collapsed grip displaying the session information. It'd also be interesting to see how they did the grid animation from expanded to collapsed...

As for the source code we are going to release it. We have a few minor tweaks to make it understandable.

I Love this stuff.....Digital Apps.....on digital displays great for all
Industries, both business and entertainment.......There should be a
great more interest in this digital area, combining convergent
integrated technologies.....using delivery method in digital only.

Ernie, I didn't quite understand the logistics that were explained during the video. You've got one PC running the application, and all of the screens are feeding off of this one application. Does that mean that you basically have the video-out from the PC going to several splitters/amplifiers to send the signal to each plasma display without any signal degradation? We never went 'upstairs' in the video to see the hardware aspect of it all.

Ernie Booth — Sat, 08 Oct 2005 17:30:49 GMT

Yes the setup was one computer driving the 40+ plasma screens. The signal was split using a digital switch box and sent over Ethernet cable to all of the plasma screens which then used a video switch to change the Ethernet into some standard video cable which plugged into the plasma screens.

We were broadcasting from 304 so if you were seeing a screen by 500 there was some degradation, but that was a result of the signal going to far in non digital form. We didn't build the infrastructure so I am just recalling what the guys who built it told us.

Tyler Brown — Sat, 08 Oct 2005 21:11:14 GMT

Thanks for the info. Were there any problems that you guys encountered while implementing this solution? You mentioned using a different Framework element when another one would have normally worked for the given application, something to do with animation. Any problems that you encountered that aren't going to be rectified by RTM?

Re: PDC Dev Team -- Plasma Screen Application at PDC

Ernie Booth — Sat, 08 Oct 2005 23:04:19 GMT

All the problems we had were due to performance. We used the VideoDrawing class instead of MediaElement for the video, because it has some perf issues in the build we were using. The WPF team is gearing up with performance tuning so hopefully they will have that working much better by RTM.

So basically you have a VisualBrush on a flat mesh in a 3D world. When the cool water effect happens, you raise and lower specific points of the mesh to create a ripple effect? Awesome!

There's only one problem that I see. VisualBrush is static. It doesn't support playing with the controls that it draws. Although it works great in this situation, it wouldn't work if you wanted the user to be able to select, say, a news item to view more information, or the video to put it in full screen (now obviously, plasma screens do not have the technology to support touch screens, yet).

Yes we use a VisualBrush on a tessellated mesh. We use some spring theory to do the simulation. Here is a pointer to the spring theory we used. We keep track of the points for the mesh is a separate class and then just update the mesh’s point collection 30 times a second. Yes the VisualBrush is non-interactive so can’t interact with any of the object’s on the screen that are being painted on the 3D surface, but as you pointed out this isn’t an interactive application so that didn’t really matter. I hope to see lots of cool physic WPF applications

Indeed, for me this will be the best bit. I will build one of these myself with old monitors and redundant cat 5. We are going to see a lot of new entrants to the world of programming being able to build appz like this. data <=> presentation is now as envisioned.

I will build one of these.

thanks a lot!!
It was an amazing video!
But could you guys post a ~~photo~~ screenshot (with a better resolution than the video) of your application? Because it's so good, we have to see this in good conditions.
Great job!

For me I'd like to know how you kept the program running in a kiosk mode while updating? Did the screens go down or was there some backend that could run on a seperate monitor/comp.

The idea of sending the video out over cat5 is nothing new to me, but i would be interested in knowing about the splitters used. My idea is to add areas to the system. Ie different sections can see different presentations, but then since this is just data driven all screens could amalgamate. It would be a seperate box per section, which wouldn't be too much of a problem.

Lastly I would love a few specs on the graphics hardware. I'd be tempted to buy a big box to run all of this, especially when i get the idea that the transitions were poor on perf due to pre beta bits, which could be sped up. And finally i may had a touch screen aspect to this for use on smartboards.

Excellent job. pm me and we can talk. All credit to yourselves of course but i'd love to implement this.

We had two computers connected to a video switcher both machines were identical in configuration and software. The switch box allowed us to change the output video signal to the monitors from one PC to another.

So when we needed to update the software we'd just switch to the signal to the other PC and make the update.

They were high end DELL workstations with killer video cards. I don't have the specs handy hopefully Ernie can reply with them.

From memory: A Dell with 2 Dual core processors, 2 GB of Ram on PCI-e motherboard, Dual hard drives and an ATI Radeon X800XL. Is what we used for Scarab.

Lots of memory and a good graphics card.

Hi Earnie,
You wrote that "the VisualBrush is non-interactive so can’t interact with any of the object’s on the screen that are being painted on the 3D surface". Is that possible anyway? Can I design sort of a VisualBrush that allows me to interact with the basic controls being rendered upon the mesh?

thanks
