Most infrared controls transmit a series of digital encoded control signals.
Kind of like sending ASCII text characters, but the same sequence is sent
as long as you hold the button and the number of bits varies per manufacturer.

Sorry to say that someone has beaten you to the idea.  I forgot who, the
magazine ad is at home, but someone has one out that will remember three(?)
different devices.  It was reviewed and did an excellent job.
