Some more nitpicking.

Not exactly. Bandwidth is a signal processing term. Udi, thus, refers to the 
"spectral bandwidth". See 
http://en.wikipedia.org/wiki/Bandwidth_%28signal_processing%29.

I think Udi meant to say that with the new encoding you can have 30% more bps, 
or "digital bandwidth", while using the same "spectral bandwidth", or "RF 
bandwidth".
