NTSC TV is a bandwidth hog. That is why the cable company is pushing
digital.

NTSC takes 6 MHz per channel. Digital takes 6 MHz per channel, more
if you want 1080p or higher resolution. They're pushing digital because
the set sellers want us to throw away all our existing televisions and
buy new ones.

analog NTSC takes 6 MHz for one analog program

digital cable TV is divided into 6 MHz channels but each 6 MHz channel
can carry 10 or more standard def programs or 2 high def programs on
cable..

downstream cable modem signals are the same as digital cable TV signals
