Like many other cable operators, Comcast has been upgrading its
local systems from analog to digital over the past few years. This
transition unrelated to the switch to digital over-the-air broadcasts
that we finally made in 2009 should free up an enormous amount of
bandwidth on its systems for faster Internet access and a wider range
of channels.
The "cable-ready" tuners on some analog TVs
can't read the stream of ones and zeroes that make up a digital cable
feed. If you've been using one to watch standard cable fare like ESPN
or the Weather Channel without a box, you'll need a digital-cable
adapter a much smaller add-on than a regular cable box, in many cases
free from Comcast for that set.
But if you own a digital TV
and only want to watch local broadcast stations (or public, educational

Your
DTV should almost certainly include a QAM ("quadrature amplitude
modulation") tuner that will allow it to receive those minimum-service
channels just by plugging your TV into the nearest cable jack.
Getting
entry-level cable this way can be a chore, as I've found. Without the
benefit of the usual program-guide interface, those channels can appear
in a long, apparently randomly-sorted list and then, as readers have
reported, they may also move around on that list. You also can't get
anything beyond those basic channels, because cable operators usually
scramble everything else.
Yet QAM tuning does work, even if the occasional service rep may tell you otherwise.
That's
not guaranteed to be the case in the future. Following a successful
trial by Time Warner Cable in New York, the cable industry has been
lobbying the Federal Communications Commission for permission to
encrypt these channels as they do the rest of their lineup. QAM
