The Switch to All Digital Broadcasting Is Coming, Will My TV
Explode?
No, and it won't stop working either, although you might experience some slight
discomfort.
I've been getting asked about the switchover a lot lately, and it really points out how little people
understand about the change, and how poorly the message is being disseminated.
The whole thing is a bit convoluted,
but in a nutshell, on February 17th, 2009 all full-power TV stations have to turn off their analog signal and begin broadcasting
in digital only. In theory,this will only affect people who currently get their TV reception via antenna, and they will be
able to add a digital converter box to tune in the new digital signals.
Kind of.
See, here's where it gets
convoluted. Notice the wording "full-power TV stations". There are also low-power stations out there that will not be switching
over to digital. These are community access and educational channels. Here's the FCC's description of Low-Power, Class A and TV Translator stations.
There's also Canadian TV that's received in some of the border states. That
won't be changing over to digital just yet either.
So, people who depend on antenna service, and are planning on getting
a digital converter box, should look for one that supports "Analog Pass-Through". This will allow you to use the converter
to tune in digital broadcasts, or use the TV's tuner to continue receiving analog broadcasts.
The digital changeover
may also affect cable subscribers, depending on the system you subscribe to, and here's why:
Right now most cable
companies are sending out both digital and analog signals. If you don't have a cable box and plug your cable directly into
an analog set, the TV's NTSC (analog) tuner searches out only the analog signals your cable provider is sending you, and displays
them on the proper channel. You need a set top box to receive the digital channels.
If you plug that same cable directly
into a new set with an NTSC/ATSC/QAM tuner, you'll get all sorts of channels you didn't know about.That's because the cable
companies have already begun the switchover to digital.The NTSC/ATSC/QAM tuners in the new sets allow you to tune in both
the analog and the digital channels, including some High Def programming, without a set top box. You won't get ESPN or any
of the other high end channels in High Def, but you will get all your local affiliates.
QAM tuners are to cable what
ATSC tuners are to antenna, they both allow you to receive digital signals. Here's a great explanation of QAM tuners.
Because the analog channels take up more bandwidth than digital, the cable
companies need to dump them so that they will be able to send us more digital (both Standard and High Definition) channels.
They're not under a mandate to switch, but they will. The only requirement the FCC has imposed on them is that they have to
support customers with analog sets for 3 years. Here's the FCC's take on it.
The way they'll do this is to require analog users to purchase or rent a
cable version of the digital converter. They've already begun ordering them from suppliers and are well on their way to turning
off the analog channels. Check out the story here.
All right, here's the facts you need to know:
Analog TV
sets that use an antenna for reception will continue to work after the changeover with a digital converter box. They
run about $50 or $60 a piece and you can get two $40 coupons per household to be used towards the purchase at https://www.dtv2009.gov/. Be sure to get a converter box that supports analog
pass-through.
Analog TV sets that are hooked up to a cable box will continue to work after the changeover
with no issues.
Analog TV sets that are hooked up to cable without a box may continue to work for
a while, but will all require some kind of box, sooner rather than later.
Digital TV sets with an antenna
will continue to work . They should have an NTSC/ATSC (analog/digital) tuner so that you will be able to pick up any legacy
analog stations as well as the new digital ones.
Digital TV sets with cable, with or without a box,
will continue to work . To work without a box the set must have an NTSC/ATSC/QAM tuner.
If you're gonna make the jump
to a new TV, always look for a set with an NTSC/ATSC/QAM tuner. It will give you the most flexibility. Beware of digital monitors,
as they don't have any kind of tuner. Be sure to check out our HDTV buying guide on berryjooks.com for more info before you make a purchase.
Bear in mind that not all digital
broadcasts are high def. Digital comes in 2 flavors, Standard Definition and High definition. The term digital is only a reference
to how the signal is broadcast, not the picture quality, although standard definition is a cleaner signal than analog and
will look better.
Also bear in mind that digital signals do not "travel" as well as analog signals, so antenna reception
may not be good in your area, even if you were getting great reception of analog signals in the past.
Told you it
was convoluted.
The only real casualty of the digital conversion is going to be the small battery operated TV's with
analog tuners. Most people buy these little cheapos for power failures or camping, and there are no plans for a battery operated
converter box. The FCC suggests getting a generator, I swear. You can read it here.
Stupid advice. If I had a generator, I wouldn't use it to power a converter
box and a 5" TV, I'd just switch on one of my LCD's hooked up to rabbit ears. Hopefully, someone will tap into this niche
market and release an affordable battery operated LCD with a digital tuner. There's a few out there now, but they're all around
$200. It would be nice if the portable DVD player manufacturers would begin incorporating tuners into their products. My Dad
used to really depend on his during Florida's hurricane season. Sometimes he would be without power for days.
So,
you're either going to need a box or a new TV pretty much any way you look at it.
Here's how I plan to approach it.
I have cable, both with and without boxes. I've already replaced two analog TV's with LCD's that have NTSC/ATSC/QAM tuners,
so they're all set. I won't replace the rest of my sets unless/until they die. For now they'll work fine on cable, and if
that changes I plan on using a cable box. There needs to be better and cheaper models in the 20" and below range before I
jettison the 20" and 14" flat tube analog TV's in our spare bedroom and workshop. Talk about missing out on a market.
I'm
also going to purchase at least 1 digital converter through the coupon program. Sometimes the 14" comes outside with us. If
the Sox are on Fox, an antenna will do the trick. It will also come in handy if the cable goes out.
Here's a decent review of whats available now for converters. So far I like the DTVPal the best. It has analog pass-through and a nice program guide, and it's a little
sleeker in design than some of the others. I'm going to hold off for a while though, as more will be coming out and the coupons
are a 1 shot deal and only good for 90 days.
