hi,

i am a engineering student trying to built a universal remote for android smartphone with the help of a dongle which converts audio into infrared signals.


i have been reading around alot but i cant seem to understand what kind of encoding method that remotes uses and how i am suppose to create algorithm for it.

i have sample a play/pause code through audio waveform and i get the bits of square wave.

i am now wondering are those code pulsing based on manchester coding and how to i decode it.i have also little knowledge as what are RC5 codes and etc.

it'll be great help if any1 could point me to the right direction in understanding all this

thanks
