The Last Days of Analog TV
On February 17, 2009, analog television signalsóthe mode of TV delivery since the 1940sówill be completely replaced by digital. Here are the basics behind this monumental change, and what it means for TV viewers.

Digital vs. analog
Simply put, a digital signal is an improvement over analog. Analog signals are susceptible to interference or "noise." Digital signals are more efficient, providing better picture and sound, and the opportunity to broadcast multiple content streams.
MYTH: After the switch to digital, I'll need an HDTV to watch TV.

FACT: Any digital television (DTV) will receive digital signals. HDTV is just one type of DTV—although the most popular—offering superior picture quality over non-HD sets.
Big broadcast changes
How dramatic is the digital transition? Eighteen broadcast channels—52 through 69 on the UHF band—will no longer exist. Since digital delivery frees up space, TV broadcasts along those frequencies will be discontinued. Roughly 145 stations in the US currently use those channels, and nearly all will continue on digital channels.

The Television Broadcast Spectrum
The newly available space won't stay empty for long. The Federal Communications Commission (FCC) has begun accepting auction bids on five portions of the 700 MHz frequency (don't bother unless you have a couple billion dollars). Additionally, a small section, 20 MHz in size, has been set aside for public safety communications. 

Digital TV
A date with digital
What will it mean to you when
stations and providers cease analog
signals in February 2009? That
depends on the equipment you use
to watch television.

There's no need to do anything if:
  • You subscribe to digital cable TV
  • You subscribe to satellite TV programming, like DirecTV or DISH Network
  • You receive over-the-air TV signals with an antenna and digital TV,
    or antenna and digital tuner

You'll want to take action if:

  • You have an analog TV and receive signals via antenna. In this case, you'll need to purchase a converter box to watch digital programming
The good news:
The government is offering converter box coupons worth $40 each. To learn more and see if you're eligible, visit the TV Converter Box Coupon Program website.
MYTH: If I subscribe to cable, I'm ready for the change to digital.

FACT: Most cable viewers receive digital programming, but some don't. The FCC estimates 35% of U.S. television homes receive analog-only cable. Contact your cable company if you're unsure. Note: Cable companies are required, by law, to continue delivering your local stations for three years past the change date.
Digital TVs

Simple facts about digital TVs:
  • Any TV shipped after March 1, 2007 must include a digital receiver
  • There may be some new televisions shipped before March 1 that don't include a digital receiver. In that case, the box must have a sticker explicitly saying so
  • TVs without digital tuners aren't necessarily "old." For instance, some HDTV models from 2006 are "digital ready"—they'll display digital signals, but only when connected to digital cable or a digital receiver.  For these, you may see phrases like "digital monitor" or "HDTV monitor" on the box

Our advice: Read carefully and ask questions if you're not sure. Check your
TV manual. Call your cable service. Many of you already watch digital television. For you, our advice is simple: Enjoy.
