I believe you are over-thinking the problem.
This has been done hundreds of times before.

Not a specific frequency, but a bit pattern. Look at

www.ee.washington.edu/circuit_archive/text/ircodes.txt

for some of the protocols. In general, the bit stream modulates a
subcarrier, around 40 KHz, which modulates the infrafred. There are
inexpensive modules containing a photodiode, a demodulator and a standard
ttl-level serial interface. Look at places like Digi-Key.
