Would ya'll agree with this?

LIRC uses their own format IR and it is not standard and it is limited in only using RC-5 protocol and only to a certain frequency.
You need an IR that can go from 30KHz - 500KHZ like professional remotes (RTI). A lot of remotes are coming out with higher frequencies.

So if you really want to know about IR protocols and how they work please search or look for Philips RC-5, RC-6 and RC-MM for 2 way communication since AT&T U-Verse uses them.
