Hello Jean Pierre,
I must direct you to the digital signage association. They are the forerunners in it all and the stats collectors as well. They hold umpteen "white papers" on every known digital signage venue that works and does not work. The DSA website is
www.digitalsignagetoday.com In the digital signage world, which I have entered as well, you will either stay on top of the trends, or you will die very quickly. I have contacted Photodex and asked several times if they could create a code for splitting a screen (screen splitting) but they failed to see the advantage to my quere. There are many, many companies out there that will supply not only the hardware but also the programming and assistance that you need to get started at a grass roots level. But, to do it right, you better have the $$$. Just go to the site that I gave you and register yourself in order to get the latest trend news. Currently, I am negotiating with a major electronic supplier for commercial grade (VERY important) LED lit, 20 inch monitors with 5 year commercial warranty being the most essential of my requested needs. Digital Signage is not new. It's been around now for about 7 years in Canada. Today's client wants split screening so that DSS feeds are constant and ticker tape bulletins are not interrupted by a faulty screen or internet feed. In Ontario, we are not allowed to install a digital sign in any venue unless it has been installed by a certified cable installer. That means more cost. Commercial grade equipment (screens) are up to 70% more expensive than home use screens. There is a lot to be aware of my friend. I've been caught and I learned very fast and the "hard way" as well. You should also talk to your insurance provider to make sure that you are covered for any thing that could go wrong with your installation. I have now come to the conclusion that running my signage over the local cable company is far more effective and costs much less. The trend now of course is to provide "touch screens" so that customers can do more, depending on the venue of course. I could go on and on about the "DOOH" system (digital out of home). It's a great new avenue to work in. No question about that at all. But if nothing else, "be on top of it !"
