that is a great article, Thx. I guess the answer to the question is
I just want to know if, other than the format, an ATSC and NTSC tuners
in the new HDTVs operate the same relative to receiving OTA signals
and cable signals as the ones I have.
IE, both have the capability to switch from OTA to Cable channel
frequencies. Channel 70 cable is not the same frequency as channel 70
OTA. Although on both channel 2-6 are the same.
Sorry the info on the site is so extensive just assumed it would be covered.
8VSB is the modulation for OTA. QAM is the modulation used in cable systems.
If you get one with a tuner that is QAM capable you should be good to go for
anything that's not encrypted.
Problem is not all stations are carried on all cable systems. In my area the
NBC affiliate doesn't allow Time Warner to use their digital signal. Tuning
on digital tuners is painfully slow making switching from cable to OTA
impractical unless the TV can hold the settings for both(mine doesn't). I
get Discover HD and TNT HD through the cable otherwise I'd be using an
antenna on the HDTV. I get NBC through an antenna connected to a tuner card
in my PC.
