With a year to go until analog TV broadcasts give way to digital, the federal government on Tuesday started mailing $40 discount coupons for digital converter boxes to consumers who requested them.

Do you need one? And if so, do you really need one now?

Only consumers with older analog TVs who get their programming solely over the air — not through cable or satellite service — will need to plug their rooftop antenna or pair of rabbit ears into a converter box.

If you use an antenna to watch television, your older set won't work after Feb. 17, 2009. One year from now all over-the-air TV broadcasts will be strictly digital.

Analog TV is going away and your old television can't receive the new digital TV signal. So, if you use an antenna to watch TV, you'll need to buy a digital converter box for your older TV.
As a side note if you use satellite or cable, you aren't affected.

Converter boxes will sell for $50 to $70 and the government will even help you buy one.

They will send households two coupons to buy converter boxes good for $40.

It's not too often the government offers you $80 to watch TV! To request a coupon, consumers can apply online at www.dtv2009.gov. The government also has set up a 24-hour hotline to take requests, 1-888-DTV-2009 (1-888-388-2009).

The coupons will start arriving in mailboxes late this month. You'll have your choice of at least 15 different brands.

You could decide to just buy cable or an HD capable TV but, don't forget about those extra TV sets you have in your bedrooms and kitchen. If they're not digital or hooked up to cable or satellite you're going to have to get boxes for them.

Here is a list of eligible boxes.
