For the last 10-15 years, the Coast Hills lobby has been the home of some really high-tech video. A pair of 27” CRT displays flanked the doors to the sanctuary. They were fed by—wait for it—RF modulated video, originally from the Panasonic MX-50, which was all composite. Yeah, it looked awesome.
A few years ago, we upgraded to a Ross Crossover Solo, but I didn’t update the video because it kept getting cut from the budget. Thankfully, we had a flood. One of the CRTs was destroyed (Yes!) and the other mysteriously stopped working. Hmmm…
So it was time to update when we re-did the lobby. Somewhat on a lark, I did a Sketchup design of the new lobby to help leadership visualize what was being discussed. In that design, I stuck four 55” flat screens on the side walls, and four 42” flat screens in front of the doors for digital signage. We ultimately trimmed down to two screens on the right of the lobby, but that was it.
The previous CRTs were fed the same signal from a DA. I wanted to be able to address each screen individually. That meant a matrix switcher. I spent a fair amount of time going back and forth between which one to buy and ultimately decided on a Blackmagic Compact VideoHub, a 40×40 SDI matrix. When I installed it and fired up the software, I immediately regretted it. The software is very flaky and after 3 hours, I never did get VideoHub Control to work. Thankfully, the other VideoHub software works, though only through USB. While it will work, I will not likely use any more of their products. The bitter taste of poor implementation lingers long after the sweetness of the low price is gone. Next time, Ross or For-A.
Anyway, each TV in the lobby—and the building for that matter—is its own destination on the router. That means we can route program, ProPresenter, or any of our four digital signage channels, or any other source to any TV. The wiring is more complex, but the flexibility it provides is pretty great.
Digital Signage Choices
I looked around at plenty of options for digital signage. We could have used ProPresenter with a couple of Dual Head2Gos; or AppleTVs or even four Mac Minis with Keynote. But I settled on DigitalSignage.com. They provide signage for many restaurants, hotels and other retail venues. It’s not the most elegant user interface, but it is very powerful. There are robust scheduling rules that make it possible to come up with really custom signage for each event during the week. The service is free, and they sell custom-built players. We went with the MediaBox 200, which is basically an Intel NUC with a Core i3 processor and dual HDMI outputs.
Two of them give us access to four channels of digital signage. It’s all accessible from the web, so it’s easy to manage. The only trouble we had was with our firewall. We had to assign static IPs to each MediaBox and open up those ports so they could communicate with the cloud server unencumbered.
Again, time will tell if that was a good choice or not, but I can report that their tech support is pretty good and the system does work as advertised once it’s configured correctly.
While you can go to Costco or Amazon and buy a cheap display for your lobby, we chose to buy LG commercial grade displays for our install. The cost is about 30%-40% more, but the power supplies are more robust, and the displays are warranted for use in commercial installations. If the display was only going to be used occasionally, or was for a weekend only use, I would likely go consumer grade. But these will be on 10-12 hours a day, 7 days a week, so they need to be robust. They can also be controlled via RS-232 if you like.
As the router is SDI, and the displays take HDMI, we had to convert. I used the Monoprice HD-SDI to HDMI converters for this job. At under $100 each, they are the most budget-friendly options around, and they seem to work just great. I’ve had one around for testing for over a year, and we’ve had no issues with it. My guess is we’ll have the occasional power supply go bad on them, but we’d have to replace all of the 3-4 times before it would have made sense to go with a more expensive option. I don’t think that will happen in the next 5-7 years. But I could be wrong…
So, that’s the lobby. Next time, we’ll talk about the PA and the lobby speakers.
