Wow, that was a good one. I immediately thought, "Oh, that's easy, it's... wait a sec... I don't know!!"


Anyway, I googled and found a fairly obscure reference to the Institute of Radio Engineers! Apparently (I didn't know this, either), according to a Tektronix page I found, the IRE later became the IEEE!


Mystery solved. Here's a page with more information than you ever wanted to know about IEEE/IRE...

History of the IEEE

IRE stands for Institute of Radio Engineers, the

organization which defined the unit.


IRE — A unit equal to 1/140 of the peak-to-peak amplitude of

the video signal, which is typically one volt. The 0 IRE point is

at blanking level, with sync tip at -40 IRE and white extending

to +100 IRE.
