TV's Digital Switch: Got Cable?

Another look at the upcoming TV switchover to a digital signal tonight .. it's coming next February, but we're already getting questions about what people have to do if they have cable pumped into their homes, or a satellite service beamed into their livingrooms?

The answer? Practically nothing. Cable and satellite services (for example, DISH Network) will make sure that the signal that gets sent to your TV set is digital. They take care of it. If you're a subscriber, you'll get the digital signal .. in fact, even if your TV is still analog, the companies can do something called "downconverting" to make sure that you get your digital signal, even if it's sent in the old analog way.

That said, you'll probably be tempted to upgrade in several ways. You may have noticed friends and neighbors getting new TV sets, and the cable and satellite services calling with upgrade offers. This is a time to (if you're so inclined) take advantage of some of these. Lots of competition (i.e., Comcast vs. AT&T) to bring you HD, new digital channels, etc., all because so many people are upgrading their home entertainment centers.

It's all well and good, and if you've been on the fence about a new HDTV, this may be the time to jump .. low prices, and (always good for us consumers) lots of choice. But remember: none of this is necessary. You'll get the digital signal from your paid service no matter what. The rest is gravy.
