The End of Analog Television

Posted January 22, 2009 12:00 AM by Kaplin

By now, you have probably heard about the big switch in television broadcasting from analog to digital coming up on February 17th, 2009. Although most people have heard about it, there are still many misconceptions about what is really taking place and how (if) it will affect you.

The first of these misconceptions is that it is not really a switch-over at all. All public stations have been broadcasting in both analog and digital for over 6 years! Next month, all public stations are being forced by the government to shut off the analog portion of the signal.

Another misconception is that a digital signal is the same as high definition video. These are two totally separate things; for an explanation of the differences, check out Digital Video Connections 101.

The next and possibly biggest confusing issue is who is actually affected by the end of analog television broadcasts. If you have any sort of paid television service such as cable, satellite, FiOS or any IPTV service then you have nothing to worry about. The switch will only affect people who use an antenna to pick up their signal, and then only if their television doesn't have an ATSC (digital) tuner as opposed to the older NTSC (analog) tuners.

$40 Converter Box Coupon Program
Due to all of the fear and confusion surrounding the analog cutoff, The National Telecommunications and Information Administration (NTIA) announced a subsidy program and offered $40 coupons for digital-analog converter boxes to anyone who sent in a request.

The NTIA set aside $1.34 billion for this program; while it may seem like a lot, at $40 each that leaves room for 33,500,000 boxes – which covers just over 10% of the US population. However, according to Neilsen surveys, only 8% of TV households receive analog over-the-air service. I guess they didn't realize households have more than one person and more than one TV.

As expected, the demand for these coupons was high and the NTIA has already gone through all the funds allocated for this program. There is a waiting list signup for expiring coupons, but with over 2 million already on the list, it looks like those who waited will have to fork over the dough for a converter box on their own.

For those who don't read down to the small print of their $40 voucher, the vouchers are not good on any converter that includes HD outputs. So if you have an HDTV and plan on picking up any of the free over-the-air HD channels, the coupons won't help you anyway.

Shutoff Tests Show Mixed Results
Broadcast stations in almost every state have tested shutting off the analog signal to determine the effect it would have on viewers, in order to help minimize later impact. But the tests have seen mixed results and call centers around the country were flooded while the tests were performed.

During a brief test in San Francisco, while 40,000 households were watching television, more than 2,500 calls came in asking for technical assistance or about the coupon program. Hopefully this will motivate some of the unprepared to get a converter box (or a new TV?)

Ulterior Motives?
Some have raised questions about the government's motives for ending the analog broadcast so they could cash in on the bandwidth by auctioning it off to the highest bidder.

Next week we'll take a look at the FCC auction and what is going to be done with all the extra bandwidth.

Anyone out there still pick up an analog signal with an antenna?
Has anyone signed up for the coupon program or tested out one of the converters?

I think there are sitll lots of people in the world who are picking up analog signal and feed to tv set. becuse there are not only readers coming from usa, but from all of the world. at least, Im still using analog signal for my tv set.

another side, what signal form will you use for rf electric wave transmitting in the space?Im afraid it s sitll analog signal

so, no matter what set are you using, the antenna signal still analog form.

You are right about many other countries in the world still broadcasting in analog after the US shutoff date. Although a lot of them are already planning for their analog shutoff. The EU has it scheduled for 2012 and China has it scheduled for 2015. (Obviously those dates could change)

And although I'm not an expert on antennas, yes, even "digital" antennas send an analog signal between the receivers but the analog RF signal is modulated digitally.

yes, you are right, I know this schedule from our media as well.

as chinese population is so many and wide spread. its possible to delay this plan.

But we can see digital tv by so called top-box. of cause the charge is higher. now programs is a problem. its a little. most of them are from usa. I mean feature film.

Dont care of my words about RF signal, I m making a literal game. I know lots of modulation ways, like frq shift key contol, multichannel quadrature encoding etc. but to be true, its out of my depth.

however, you can edit some words in your acticle to more complete.

TV will obviously no longer be transmitted at the given analog frequencies and they will most likely be used for military or industrial purposes. Personally, I am very fond of the switch over. It did cost me a few pennies to get a digital reciever, but I get more channels with better reception in a rural area. I still pay nothing and now recieve more.

It is about time the analog signal that has been around for nearly 75 years gets and upgrade. just be thankful the updates in signal don't change as quickly as pc specs, a better signal = better visual quality. if you haven't gotten on the HD train yet you have no idea what you are missing....

My apologies friend, but may I present an opposing view. After having repaired many many thousands of TV receivers since 1958, seeing many changes and upgrades take place over the years, I have developed an obnoxious attitude.

"if you haven't gotten on the HD train yet you have no idea what you are missing...."

Oh yes, I know exactly what I am missing and I choose to miss it. Yes the picture is BIG. Yes it is clearer and sharper, but until the programming improves I'll invest in food and shelter and keep watching my Non-HD TV.

I get really frustrated when I can't see what is happening in the bottom portion of the screen cause it's always blocked by logos, flying images, advertising, promos, etc. Also, I kind of like to get lost in the story and the constant barrage of crap on the screen makes that impossible.

Besides, I really don't need 150 "Watching Paint Dry" channels. Oops sorry, that might actually be more interesting. (END OF RANT)

Yes, most of the stuff on the 100+ HD channels is garbage but that is no different than any of the non-HD channels either.

When HD really matters is when watching movies or weekly shows such as Lost, 24, Heroes, etc.

Those pop up ads are very annoying but are not limited to just HD channels.

Some of you are still confusing digital with HD. By sending a digital signal instead of analog, they are sending the same information more effciently with less chance to pick up "snow" on your TV.

yes, HD and digital are two different concept. both analogy and digital can get HD, but digital has more advantage than analog siganl, no matter from interference, interact, and watch freedom.

dont complain advertise, because of them, we can get free program at home, or you can go to theater to see digital movies. no ad, but have to pay.

freq resources are limited, so we have to turn to digital, for example, if use analog, in range of 0-6mhz, we can have only one program, but in digital, we can get up to 16 channels. and goood quality, thats why people wish to get digital sisnal.

we can say simplely, digital tv is another internet. but wide band and hd. huge data strings.

The only reason for digital HD TV off course, is to get the sponsor's name bigger on the TV screen.

I totally agree. If someone wants only watch the local news TV analog transmission is sufficient. If they want to watch more programs they can chose from several options but I think switching to digital is only the business of the advertisers and TV manufacturers.

I had not heard about the coupon program running out of money - goog thing I got in early. Anyway, I refuse to pay for all the garbage programming so I use the rabbit ears for what little I do watch. We used to pay for cable when our youngsters were real young, but the cable company kept pushing the programming we wanted up into the costlier packages so the boss said "enough!" The digital conversion has went well - better picture, more channels, still using the rabbit ears!

My two biggest complaints are:

1) Audio/video sync problems can be real annoying... about like watching a Japanese movie with voice overs.

2) Signal is more susceptible to weather interference than analog.

I like a couple of others here am tired of having my viewing area reduced against my will by news crawlers, logos, PIP zoom to reduce what you're watching (usually a sporting event) while some VIP, you usually don't care about is being interview in the larger main area of your picture.

Too bad it seems it has gotten to be mostly about "the money" rather than giving the consumer what he/she wants. I'd much rather subscribe to satellite/cable on an a la carte basis -- pay for the channels I want and forget the rest of the shopping channel, infommercial channel, junk.

My experience with the converter box..new TV signal. We get two converter box coupons and buy a box. We get Fox intermittently and when it does not come in it just freezes, so you loose the gist of the program completely. The analog way at least you always had sound. I buy the biggest roof top antenna and booster that I can find. I get a friend to help put it 20 feet above the roof on my home and Sunday comes and I still can't get the football game. The dude at the store says hay just buy this new dvd-vcr recorder it has a much better receptor device in it. So now that I have about a grand invested in free TV you guessed it. The new way is not reliable. It freezes up and on more than one channel. I should have known better than to trust Government and big business. They have taken away my best news source. They have sent my work over seas and I will not buy TV. Maybe they could just steel some of the Analog Channels? Let us keep part of it for poor people to watch the biased news.

You have to separate the program creators and the broadcasters.

The TV channels put in the news crawlers and the logos. The broadcasters just transmit the digital signals.

The digital signal is exactly as susceptible to weather as the analog (as it is analog after all). With the help of Forward Error Correction and Reed-Solomon it can maintain better picture quality even in bad weather but if it reaches the limits of the FEC and RS the picture is gone. In a good system this limit enables watching TV even in weather where an analog picture would be barely visible. Also there is no ghost picture opposed to analog TV, but for that the time guard interval in the signal should be well chosen for the terrain.

We were just preparing for the DVB-T here in Hungary back in 2006 and there was only a test signal in the air, not the full power broadcast signal, and we managed to receive crystal clear picture with literally a single piece of copper wire in a cellar with a good set-top-box!

Now that the final version of Hungarian DVB-T broadcast started in last December, we got problems because of the crappy receivers. There is not one on the market I would recommend here. Every one of them has some software issues, some of them affecting the picture quality. Cheap boxes have the most problems. I work for a company selling STBs mainly for cable operators and we were also trying to get a good box for the start of terrestrial digital TV but still today we do not have a box we can sell. The ones which work are too expensive for the those who watch free TV. The others are not working properly.

As I understand the reason for turning off analog TV is to free up some frequencies. DVB-T can be a good thing but for that it needs to be planned properly both from the broadcasters side (modulation, symbol rate, guard interval, length of FEC, etc.) and from the STB distributors side (tested, working STBs). The benefit is not just that you can put in several channels into a TS and all that to replace a single analog channel. EPG is also useful and comfortable for example.

If you have been keeping up on this story, the senate passed a bill to delay the shutoff date until June 12th, 2009 but yesterday the House of Representatives voted it down (woo hoo!)

Also check out the other side of this story that hasn't been getting as much attention. The FCC's 700Mhz Auction

The switchover really needs to be pushed out once again: Broadcasters are still not ready and will probably not be for months up to a year or more; the conversion box program, conceived by Government as it was, has become largely an overpriced fiasco; most if not all converter box purveyors (real or virtual) remain in non-compliance with rules promulgated for manufacturer and distribution of the boxes.

Too bad we can't see the end of TV, period. Life was so much simpler and productive before TV.
