Reverse engineer Fair-Play scoreboard controller? Reverse engineer the radio signal?
3 replies, posted
I'm working on a program for my high-school's TV station. I'm making a new program for creating the on-screen graphics during our live sports broadcasts. Currently we have a simple on-screen scoreboard, and we use a picture-in-picture of a camera pointing at the scoreboard timer to display the time.
[URL=http://www.fair-play.com/products/controllers/scoreboard-controllers/mp-72/]This is the wireless scoreboard controller my school uses to control the scoreboard.[/URL] It stores the score and [I]time[/I] in memory and sends this information to the scoreboard via 900 MHz radio signal.
Is it possible for me to reverse-engineer this signal to have a laptop (with some sort of receiver) be able to know the current time displayed on the scoreboard? It'd be great to have the on-screen graphics for the live broadcast display the actual time itself instead of a cheap PiP.
Yes, it is possible.
You just need to write the software to interpret and decode the wireless signal.
Too much effort for little payoff though.
What Contang said. It would require way too much effort.
What you could do would be to use some OCR. Get the snapshot of the scoreboard every x seconds, turn up contrast, crop the image to the score and run an OCR library over it.
That's definitely doable.
Hmm, haven't even thought of using OCR.
Great idea
