What's going on with HD broadcasting?
 

I've heard several 'opinions' as to what is going to happen in 2009 when HD TV broadcasting becomes the norm. An Ad on PBS said that if you're currently on cable or satellite you don't have to worry, but if you have an antenna (rabbit ears) you will need a converter. An aquaintence told me everyone that doesn't have an HD-capable tv will need a converter regardless of source.

So, can someone give me the real 411? :confused:

Yes, except only in the US. The CRTC in Canada is taking a wait & see attitude as far as I can figure out.

... leading the way as usual, eh?

The 411 is:

If you use rabbit ears, then you need a digital converter. EITHER your TV has one inside (it's an HDTV) or you need an external one (HD or non). The "free" converters are non-HD. If you're TV is not HD capable, then get the free converter. If your TV is HD capable, and has an internal decoder (HDTV) then you already have the setup ready. If your TV is HD capable, but does NOT have a decoder (it's an HD monitor, or one of the early HD CRT sets) then you want an HD decoder, which is NOT free. The Samsung DTB-H260F is the best on the market right now (and probably will be the last ever made).


If you use analog cable, then you can continue to use analog cable until they make the decision to go digital cable only (might be a few years)

If you use digital cable, then you're clear for the foreseeable future.

All satellite is digital (I think), and will not change in the near future.

all TV sets being sold todat are digital, and 95% of the or more have internal digital decoders, and require no converter box.

Thx Mike.

All broadcast TV is not going HDTV. It's going Digital.

Currently over the air signals are analog. That will change in February, when these signals go Digital.

So only the oldest, non digital TVs, not hooked up to a cable or satellite box will not work. I can't beleive there are that many out there.

I haven't given it much thought, but I think the TV companies might be behind this whole thing. People can get $80 towards the purchase of either a converter box or a new TV. What do you think most people will do? Yup, buy a new TV.

Here's whats happening http://www.fcc.gov/cgb/consumerfacts/digitaltv.html

How much more HD do you need over the air? There's lots already!

MOST OTA signal is digital right now. I get 2 or 3 digital channels for each analog channel.

Or HD capable sets that do not have a decoder. I have one of each, and do not plan on getting rid of either (I'll put my Sony HD CRT against any LCD or Plasma).

That's a joke, right?

Very good point. Everyone thinks you need an HDTV. You don't, you just need a digital tuner. Of course, many new TVs are HD capable, and ALL new TVs have a digital tuner. And unless you watch TV via rabbit ears or antenna, it's a moot point anyway.

So basically it's something that will adversely impact the poorest people.

Too bad we have dish service (and my wife actually uses it). I'd love an excuse to kick television out of this house permanently and completely. I despise it. Total waste of time.

I'd be willing to bet that most people in the projects have a TV and cable. I'm sure we're paying for it. Isn't that a basic human right?:rolleyes:

No it will impact suburbia if you don't want to pay $50 a month for TV (as in too cheap to buy cable).

They picked the poorest system they could and is almost unwatchable on windy and or rainy days due to poor multipath rejection.

dont know what it happening in the great white north

but in the USA, signal is going to DIGITAL from ANALOG. some programs are taped in HD, has nothing to do with how it is sent out. co-worked uses rabit ears and loves the shows in HD. not sure if he has gotten the box yet but come february 2009 without it you will probably get snow IN HD

they explaned the whole thing on all the ads they have been running forever...and pbs has a more dumbed down version

if you have rabit ears GET a DIGITAL converter
if you have cable with a box NOTHING needs to be done
if you have satalite with a box NOTHING needs to be done.

if you cant understand this how did your figure out the interweb?

You might note that the OP lives in British Columbia, so all of your info about the FCC mandated transition in Feb 2009 means nothing north of the border.

Here's our announcement:

CONSUMER NOTICE

After August 31, 2011, all analog televisions will require a converter box in order to receive Canadian over-the-air broadcasts using an antenna. At that time, all over-the-air broadcast signals in Canada will be in digital-only format. Canadians using satellite or digital cable services should see no change.

U.S. television stations broadcasting over-the-air into Canada will make this change sooner, in February, 2009.

HD is SEPERATE. The signal can be digital and NOT HD. However, some over the air broadcast stations are in HD. Some are not. It depends on the station. Again, digital is NOT the same as HD.

changed it for the ones that didnt understand my post the first time

No. I explained it complete earlier. If your coworker (or anyone) is already watching digital or HD over the air, then they do not need anything else, they already HAVE the decoder somewhere (probably in the TV). You ONLY need the converter box if you do not use cable or satellite, AND you use rabbit ears on a non-digital television. That's it, nothing more. It will be the same in Canada in 2011 as it will be here in 2009. Period.

well bully for him...them fancy thin tvs do everything now.:)

I wonder if I could set up a high power analog TV transmiter in Mexico and send free pirate TV into the USA?
:D:D:D

I've seen coupons for converter boxes. How does anyone get $80 off of a new TV?

Frankly, IMHO this should have changed years ago. The broadcast quality of standard TV hasn't changed in 50 years.

Let me dispel this myth. I'm one of those who watch Over-the-air (OTA) digital TV (Yes, I'm "too cheap" to pay $50 for 30 channels of crap. The free crap is sufficient.) Our reception is great. No matter what the weather is, the reception is ALWAYS better than the analog channels.

BTW: The broadcast towers are about 20 miles away. We pick them up using a small gable-mounted outdoor antenna.

Here is the link for the coupons. https://www.dtv2009.gov/

You don't need HIGH power, you need LOW power. The digital switchover is exempted for very small, low power local TV transmission ;)

I get perfect reception, through an entire apartment building, from my $15 powered rabbit ears. Only during the worse storms do we lose reception. If I had a nice roof mount antenna (when we get a home...) I expect to pick up every station 100% of the time.

Also, with digital OTA, you get several stations that are purely local weather/traffic/news...try THAT with cable!

I'm not too cheap to pay for cable, I just don't see any need for it. Why pay for some luxury item that ultimately takes away your useful free time and melts braincells at the same time? If I sold a vitamin that wasted your time and made you stupider, I'd be banned from the FDA and sued up to my nose...but cable and satellite do it day in and day out ;)

I guess we will have to see what happens when they pull the plug
http://en.wikipedia.org/wiki/8VSB

"a Centris study released in February 2008 revealed "serious 'gaps' in digital TV signal coverage across the country "when taking into account 'outdoor receiving antenna sensitivity and multipath interference.'" As a result, the Centris study states, "certain households - for example: those that are not elevated; are surrounded by trees; or have set-top antennas instead of roof-top antennas; among other factors - are at higher risk of having limited or no signal coverage. Centris surveys reveal that 75% or more of over-the-air households have only set-top antennas."[3]"

Um...a fool coulda stated that. It does NOT state that those people will have no TV. Naturally, someone running cheap rabbit ears will have a higher risk of losing signal than someone with a wide band, full sized rooftop antenna. Naturally someone in a geographic bowl has a higher risk of losing signal over someone on a hill. So? If they both DO get signal, then they both get the exact SAME signal.

Digital signals from transmitters are more directional than analog signals. If you got a good picture with ears with analog, it doesn't mean you will when it changes to digital. A poor digital signal is exponentially worse than a poor analog signal.

With digital there isn't snow or something less tolerable but still watchable. Most of us have seen the mozaic scrambling annoying digital mess that a poor digital signal can bring. It's either a great picture or something unwatchable.

I'm fortunate to have line of sight to the LA transmitters and there's still a nine foot full antenna on my roof.

Not exactly. The NTSC channel bandwidth is 6 MHz and I think that is what is assigned to the new digital stations. The bandwidth required for a raw 1080i image is well over 300 MHz. The compression schemes and error correction to accomplish this require a fairly continuous accurate data stream.

What you see as a ghost around the image or light snow now will be picture and sound that drops out until the decoder fills up again -- to me unwatchable.

I think it is generally agreed to that an indoor antenna will be unusable except in the most ideal conditions. Do you have a TV on your dresser you turn on while getting dressed not hooked up to a central antenna? For me that will go away.

antennaweb.org says I am 15 miles from all the transmitters but they still tell me I need a highly directional antenna.

Pazuzu,

You do get all those channels with cable. I'm sitting here right next to a tv hooked up to cable and I get about 3-4 channels for each network. 4 is NBC, 4.1 is NBC HD, 4.2 is Weather, etc. And all I have is the basic cable.

I think why some cable TV's don't get those channels is that you have to go through the channel programming setup again to pick 'em up.

And like I said OTA signals are easier to get in some places. In NYC\nnj there is a lot more interfence than most places.

We pick up the 4 major networks in over the air HD via the build-in antenna on our LCD TV. They come in great, regardless of the weather. Not sure where the antennas are, but they aren't in my backyard.

But there aren't any trees in Wichita. They create dynamic multipath. It is rather flat there also.

Is that why Wichita has been a Tree City USA for 22 years? Boy, they should really review their criteria.:rolleyes:

What affect does the multitudes of stray bullets and 28" rims have on reception in St. Louis?:p
