What is the difference between ATSC and DVBT bda driver?

TheMSsForum.com: The Microsoft Software Forum

I have developed a bda driver for dvbt, and now, I want to make it
compatible with atsc.

I modified the KSNODE_BDA_COFDM_DEMODULATOR to
KSNODE_BDA_8VSB_DEMODULATOR, should I modify other things?

Not much else, actually. It usually requires a separate demod chip, the
SAW filters are usually different, and the tuners for ATSC sometimes use a
different IF from DVBT, so you'll have to watch for that.

And one more "small" thing is that ATSC tuners today are almost requried to
support analog. There is little to no demand for ATSC only solution unless
this is a data-over-the-air-delivery card or some other specialized device.
Adding analog is a bit of a pain with its own small quirks here and there.

Absolutely correct. Media Center, for example, will not handle an ATSC
tuner unless there is also an analog tuner in the system.
