This can be very confusing.
If you just receive basic cable from Comcast, you probably don't need
any converter box. If your set is analog, the digital signals---the
only kind after the transition---will be converted to analog for
you. If your set is digital, you should get the full digital signal
from comcast. I've already checked the latter with my digital set.
In our building, we can get basic cable without a box, just by connect
ing our sets directly to the cable without a box. You tune with the
TV controls. I have a Tee connection for our digital HD set which
allows us to use this direct connection or to go through Comcast's
digital HDTV box. With the direct connection, I've been getting the
full HD broadcasts from those stations which have been broadcasting
them.
If you subscribe to a digital package, providing considerably more
than basic cable, then you presently need a converter box, whether
you have an analog or digital TV., and the same will be true after the
switch to digital.
One aside. For HD, you will actually get better reception over the
air than you would through cable. That is because the cable
companies use compression algorithms and thereby lose some
information. Of course, with over the air reception, if the signal
is weak, you will no longer get anything at all after the switch,
whereas before you might have got a snowy picture. In urban or
suburban environments, you may need a new antenna to get all the
stations you got before.
