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.
