IR TV Remote Codes Answered

With all the projects on the net with the raspberry pi, I cant seem to find the one I am looking for...

I want to be able to point any tv remote control to a sensor on the pi, and get the IR code on the display.
This way I can use that code to program any button I want on a universal remote control.

for example, if I point my dvd remote to the pi and push the play button, the display would read 4753.
Then I would use this code to program my universal control's play button.

I know I have seen this project before, just don't remember where.

Any Help?

Unless your computer knows all of the 99 protocols, the best any computer including pi can do is record the transition durations and play them back when requested like a tape recorder or storage scope...

You can assign a name to the record and then signal a key to have pi send that record...

That also assumes there is no back and forth handshaking going on between the TV and remote !

And how would you know the code?
I mean the sensor is not reading a number but a sequence of light.
There are a lot of different ways and protocols to generate IR signals...
Your 4753 reflects something the remote knows how to interpret to generate the code in question - you need the codetable and all corresponding codes to make it work.
