Any one have a list of web links on this subject? I am trying to build a TV Remote Control Signal reciever that can store the last 'X' commands in memory for research purposes. By commands I mean channel choosen/selected etc. Regards, Salman
Not a solution but maybe a starting point would be the JP1 group on Yahoo. It is really about unversal one for all remotes but the protocols and commands for most devices are fairly well defined one way or another in the threads, links and files sections.
There are a few companies in the world that have a full database of control codes (eg which make and model uses which command to do a particular function) the makers of universal remotes licence their libraries from one of these. Perhaps they could help?
You might also be able to use a Pocket PC to capture and log the data you want? I know that a few programs exist for Pocket PC and similar palm devices to allow them to be used as universal remotes. They should also be able to do the reverse.

There is a progam called PCIR, I believe, that allows one to record and play IR signals using the parallel printer port on a PC. It runs ok under W98SE. But XP and W2000 don't let the software access the hardware directly, so that may prevent it from working.
I used it to record some remote controls. I connected an IR LED directly to the port without any amplifier, and I put the IR LED right near the VCR. It picked up the output okay. So all you need is a 25 pin male connector and the IR LED. It uses some other circuit to receive and record the IR.
This morning on CBS's Sunday Morning, they had a segment on high tech gadgets. They showed a really fancy universal remote that connects to your PC to download the 'programming' from the company's website. So you can "throw away" all your old remotes. Right. The big problem is that this remote costs _two_hundred_bucks_, which is a lot more than the 60 or 80 for some of the fancier universal remotes, which are way overpriced, IMHO. Like I can buy a fully loaded VCR and DVD player combo for that much!
And what do you do when your dog uses it for a dog bone? :-(
