how to figure out what ir code

Whats up,

i am trying to operate my Hifi with an arduino and an ir Led. First I detected all the different IR signals from the remote control with an ir receiver. But to send the ir signal i need to know what kind of ir standard the remote control is using. For example i get for the power button the following code:
49625287.
Does anyone know what ir standard it could be, or how i could figure it out?

thanks

Why do you need the standard, when you already have figured out the code sequences?

Install IRremote or IRlib and post the output from IRrecvDump example provided with the libraries.
