I just got a new LCD HDTV RCA L32WD12. There is no cable service offered in my rural area, and our local stations in Springfield, MO. do not transmit in HD over the air. When I got the set, I hooked it up to my existing DIRECTV analog SD box. The picture quality was OK, but disappointing and seemingly not as good as CRT. Pix looked like it had poor focusing and plenty of artifacts, some channels better than others. I realize that some of this is characateristic of LCD's as well.

Today, DIRECTV came out and installed my new HD box, and wow! I was really impressed while viewing true HD material at 1080i. The box was hooked up using the component jacks on the tv. I am well aware there are better LCD sets than RCA out there, but can honestly say that I have NEVER seen a better picture on ANY tv, even plasma!

My question to anyone is there anything else I can do to improve SD on my set? Fortunately, I am able to change the format (screen size) on the set, which helps to some degree. As I said, ALL the HD channel broadcasts look superb.

Unfortunately, there are only a few HD channels available to me, and of course, most of the stuff I prefer to watch is in SD.

I shoot and edit SD broadcast commercials for cable tv, which at least gives me the ability to distinguish good and poor picture quality, but I don't really know much else....

Any response as to improving picture quality when viewing SD channels would be appreciated!

Thanks,
Bob

I just bought an HDTV and when hooked up to my standard Dish Network box, the picture looked good as long as nothing noved in the show. If something moved then it got fuzzy around the moving araes edges. I have now been told that for any LCD tv to look good, would have to get a dishnetwork HD box and even an LCD tv with 480 LRs would do this. Does this sound right?
Thanks

Benn must be a troll to say the things he/she said.

What channels were included in the "tens of HD channels offered by satellite providers?"
If it was the network stations, they were probably being picked up using a terrestial antenna. Those are "local broadcast television."

In my experience, it is those local HD feeds that provide the clearest picture. I've been watching HD OTA for some time now, even before I got VOOM almost 2 years ago. Don't confuse the multiplexed or upconverted SD feeds found on many locals with true HD. Those upconverted feeds resulting the in the pillarboxing (aka black bars on the side of the picture.

BTW, this is something I know more than a little about, having been a broadcast engineer since the '80s and even a chief engineer in cable. I'm now working on the manufacturer side of the system, and the number of customers with misperceptions about what is HD isn't surprising.

When the cable guy came to install our new HD/DVR decoder box for us, he hooked up the TV to it and verified that we got a signal. I asked "Um, why are those black bars there on the edges?" He said "I don't know, it's always like that when I install these things." He really had no idea what it was supposed to look like. (Our issue was the wrong type of cable in the wrong input, easily resolved after he had left)

If an HDTV set has a scaler (analogus to interpolation of a digital photo) standard signal will look much better on an HDTV.

Do a search on the web or look around avsforums.com, there are some settings you can change in the factory service menu (technician menu) that disable some of the video processing for SD signals and improve the SD video quality pretty significantly. Best of luck.

"Set top boxes, my aching whatever. I have HDTV, have had for a long time, and I have no plans, ever, to get an on-air decoder. I don't even have a standard TV antenna. Satellite TV is bad enough; local broadcast television is intolerable."

Offense intended, your Satellite receiver is considered a set-top-box, guy. As for cable being a good add-on for HD reception, there are only a few channels that broadcast HD that arent networks.

I disagree with the first poster who said SD broadcasts look better on his HD TV,

"And damned if this sucker doesn't display regular, standard-def TV sharper than I've ever seen it. Yeah, it's 480i, but it looks a helluva lot better than my mother-in-law's 2-year-old non-HD-ready TV. So I don't think this is entirely placebo. This HD-ready set has better video quality even at SD resolution."

I have a Samsung 1080P set and SD looks horrible, much worse than on my original non-HD set - using HD set-top connected by HDMI. It may have to do with the size of my new set being twice as large, so the video is scaled to fit the screen...

Most HDTV sets are not capable of displaying the HD signal due to reduced resolution of the display. To view all that HD is capable of you need a screen that can display 1920x1080 pixels. There are very few sets that can do this. The next level down shows a little over half of the available definition. For comparison, HD should look like a 2M digital photo blown up to the size of your TV screen, Vieweing a 5x7 held at arms length shuold give you some idea of what to expect.

Some of you all really need to go do some reading at:
---
www.dtv.gov
---
Which is an FCC site with excellent background material and the real legislation and regulations. A very few of you either did so or got good info but most of you and the public as a whole misunderstands, and what's worse, sincerely believes they know what they need to.

Are you kidding me? You obviously have not actually explored what is available in terms of digital transmission from your local carriers. Even here in the relative backwater of Roanoke, VA every single station is broadcasting in digital and have an array of HD programming that easily rivals what's available on digital cable and basic HD satellite packages.

Additionally, locally broadcast HD doesn't suffer from the compression issues encountered with satellite and cable providers, so the image is actually higher quality and relatively free from motion artifacts.

I'm fully in support of the broadcast digital revolution... why pay a huge monthly fee when you can get the exact same content over the airwaves for free?

Many families pay for cable and then primarily watch the networks anyway. The only reason they do this is because their memory of poor analog reception has made "cable" synonymous with television reception. That day is over, and people have no reason to pay a cable company for what they can receive for free at higher quality. That's the reason for the legislation... empowering the consumer. I think it's great.

"and just for fun pluncked down an extra $50 bucks for an HD antenna"

Got news for you: an HD antenna is *just* an antenna. HD signals are carried on the UHF spectrum, and you can pick them up just as easily with a 30-year old UHF antenna than something that is marked "HD ready." A lot of the "HD" stuff you see out there is marketing hype created to make you pay extra for stuff, much like the "digital ready" speakers that were being pushed when CD's came out. Speakers are still analog and there is nothing special about designing them for music from CD's. Same thing with antennas--just get a good UHF antenna and if you don't have too many trees or too much multipath, you'll be very pleased with off-the-air HDTV.

That being said, for those of you who have never seen a true HD signal, you owe it to yourself to see what your TV can do. And as some have pointed out, the digital broadcast of standard definition content tends to look much better than the analog version of the same thing. That is because with digital transmission, there is no "snow" or "ghosting"--you either have it or you don't (or if you have a weak signal, the whole picture drops out). Not only that, but the audio is much better. Ultimately, as transmitters come up to full power and the receivers get better, people are going to want digital broadcast because the picture is better--HD or not.

Also, if you own a nice set, you should really go out and get the Avia DVD and use it to calibrate your set. TV sets are manufactured to look best under the bright showroom lights, and by properly setting your contrast particularly, you will not only improve the picture but add life to the TV (especially if it is a CRT-based set).

We recently bought an HD TV, and just for fun pluncked down an extra $50 bucks for an HD antenna. To say the least, we were absoulutly blown away. In our market, (Raleigh Durham) every network station and public TV station is broadcasting in HD. Additionaly, there are smaller community stations broastcasting a digital signal.We receive eight different stations in HD. Additionaly, most of these stations broadcast from two to four different channels with different programing and at different resolutions. We are seroiusly rethinking why we would need HD cable.And let me also say that a SD signal is far superior to any analog broadcast. At least on our TV.

We are going to get a converter for our Sony analog TV, just because there is so much more programing in broadcast digital.

I don't see how you can state that the fact that a third of people are actually not viewing shows in HD supports your prejudice that HD content is not that impressive. It seems just to prove that people buy new technology and don't RTFM. Could it be that perhaps you watched "HD" w/o it being turned on? ;)

"In fact the FCC is mandating HDTV, not just "digital" transmission. By March 1, 2007 all TVs of all sizes must be only receive HDTV signals."

Miguel Nunez, you just contradicted yourself. Merely because the FCC is mandating that TVs can receive HTDV signals, does NOT mean that broadcasters must transmit in HD. Those are two entirely different concepts.

And in fact, there is no law or statute of any kind that says broadcasters must transmit in HD at any time. All broadcasters are going to lose are their analog transmissions. What they do with their allotted digital spectrum is up to them.

Most people buy their technology not because they need it, not because it is better than what they have been useing.. But because they are TOLD they should get it, or their keeping up with the Jones's - yes it is the fashion. Many capable of posting here would know and appreciate the difference, many more the fact that you can see the ball in the football game makes the picture Hi Def.
What many people Call a Good picture wont even pass as poor Standard def digital.

Reading these comments is funny because some of you posters claim to be informed, yet spew out another misunderstanding.

Let's call it what it is. The digital broadcasts you're talking about is called ATSC as opposed to NTSC, which is the analog feed that will eventually get phased out.

ATSC does not necessarily equate to High Definition. You can view standard definition programs with a digital (ATSC) broadcasts with your HDTV screen, and most of it is still standard definition.

The guy who didn't understand the comment about non-videophiles not finding HDTV impressive is obviously missing the point of the article that these people are under the impression they're viewing HDTV when they're not...so why would they be impressed?

Yes, true HDTV is superior, but watching standard definition via your HDTV's NTSC tuner is like sticking a wad of gum on a gold band and calling it a diamond.

Why in the hell is the FCC doing this? No one really needs HDTV. How about getting fiber to low income neighborhoods, making sure everyone has high speed internet access seems more important than being able to see better skin tones on television.

HUH? Have you ever SEEN a real HD broadcast. It's phenomenal compared to the same thing broadcast in standard def,,,at least it is on my 46" HDTV that is getting (admittedly few) HDTV channels (damn you Time Warner).

Broadcast? Broadcast?

I rather doubt the majority of HDTV owners will be bothering with set-top boxes, ever -- because they're getting their HDTV feeds from satellite sources. If you've got the money (and sense) to pick up an HDTV unit, wouldn't you understand that the lame local programming you suffer through is best ignored for the tens of HD channels offered by satellite providers?

Set top boxes, my aching whatever. I have HDTV, have had for a long time, and I have no plans, ever, to get an on-air decoder. I don't even have a standard TV antenna. Satellite TV is bad enough; local broadcast television is intolerable.
