Many analog tuners are used by ATSC decoders too. The FCC
allocates the same channel frequency and bandwidth to both
services so the same tuner can be used for either one.
These tuners have their own i2c address. They are not a
part of the decoder chip.
Currently these tuners have separate code in video4linux CVS
and dvb CVS that does exactly the same thing. The code in
video4linux CVS is configured by tables and supports a
large number of the analog tuners. It would be nice if the
code in video4linux was shared instead of having to
maintain code that does the same thing in dvb CVS for
tuners that are used by both analog TV and ATSC.
