I'm not sure how far free-to-air digital transmissions have come so far in
the States. Over here in the UK, there are now four systems running in
parallel - original UHF analogue, cable ( both analogue and digital ),
digital satellite and UHF digital free-to-air terrestrial. Many of the HDD
recorders here have dual tuners for UHF analogue and the 'Freeview' digital
terrestrial service, which in theory, can be received with your existing
antenna system ( Ha! ) Many TV sets also have similar dual tuner systems,
but inputs to both are not always available via seperate antenna sockets on
the back ( back to " you can use your existing antenna !! " ) They are soon
to start switching off the analogue service here, region by region. What's
the situation over there ?

Analog terrestrial broadcasting is due to end early in 2009. Cable
service is both analog and digital in most areas, but the cable box
puts out an analog NTSC signal. Some of the digital cable fare is
"free" (unencrypted), and can be received by any TV with a QAM tuner.
Our government has mandated that all local terrestrially broadcast
digital/HDTV stations carried by cable companies should be available
at no extra charge, like their analog counterparts. The majority of
HDTV sets being sold will tune NTSC, ATSC, QAM, and 8VSB signals. Some
have two RF inputs on the back, some only have one but will "remember"
channel settings for two different RF inputs, and some have only one
RF input and one memory group. LCD seems popular for smaller sets, with
plasma getting the nod for larger sets. Large plasma HDTVs are
OUTSTANDING!
