In Reply to: Cablevision digital cable, crappy hdtv quality? posted by Frank25 on November 26, 2006 at 18:31:02:
AS GTF stated, HD isn't quite ready for prime time. More pecifically, the networks don't quite have it down right. They are still learning. Some networks/stations are better than others. CBS as a rule seems to be ahead of the other networks. Its not uncommon for someone at the staion to forget to flick the switch and turn on the HD signal until the firast batch of comercials.
That said, cable companies frequently have their own problems sending the sinal, and if you are close to your local stations, you may wish to try to get OTA. I find this usually gives me a better picture.
Lastly, the Scientific Atlanta boxes are famous for being dog-doo.

I have to put in a good word for my SA 8300 HD DVR box (Time Warner NYC). While I was infuriated that it didn't support HDMI (there waws no sound and no setting in the "settings" menu to turn it on) the HD picture is positively flawless. No video noise of any kind. On very rare occassions there's a tiny bit of pixilation but it tends to be sporadic and then goes away. I do wish there was more HD broadcasting and I'm entirely befuddled as to why big ticket programs like NY Jets games and shows like 'Survivor' and 'Deal Or No Deal' (which are on during prime time) are still in SD.I mean how expensive is it to buy a couple of HD video cameras?
Consumer grade ones are on the market for a few hundred dollars.
What gives here?

I hope it's HDMI or at least component. My Cablevision box works fine, especially on HD sports, Leno, Conan and Letterman. Crystal clear, stunning, absolutely no noise of any kind. What kind of "artifacts" do you mean? If you're worried about the picture losing definition as the camera pans, then it isn't the TV or the box--it's the technology. That's what happens when the camera pans on even the best equipment. Just make sure you aren't using the S-video connection.
im using cthe component connection with decent cables. The artifacts are mainly on the grass of the feild and its sort of blockyness, its not there when the camera is still but once the action starts you can see it.
Yeah, I get that, too. It looks like the sod has been planted in clumps. It's normal for detail to be blurred or otherwise indistinct when the camera is moving. If it isn't there when the camera is still, then it's the movement of the camera. I notice it on my set mostly on travel shows when the camera pans across treetops and all I see is a green blur. Then, when the camera stops, leaves appear! My set has been calibrated, too. That's just the way it is.
I have the coaxal cable going straight to my TV without any box at all. I also have an antenna in my attic that came with my house.

Somewhere around half of the prime Time shows are in HD. I don't watch that much TV and don't really care for most primetime. I know Lost, the CSIs, Medium and some horrid sitcoms are HD. There is Titan TV-a listing of digital and HD shows on broadcast TV if you are interested.

Whats the best way to set up my Explorer 4200hd with my Samsung crt hdtv?? My tv is compatible with 480p and 1080i. The cable box has 4 settings for picture output. It has Fixed, pass through, upconvert1 and up convert 2. Up convert 1 up converts to 480p OR 1080i, the up convert 2 gives 480p and 720p. Im using Upcionvert1 since thats the resolutions that work with my tv. Would using the pass though be better maybe would it get rid of the extra video processing that 75% of the time I don't need?? My Tv already up converts all SD to 480p, but im not sure what its doing on 1080i stuff? Its a Samsung tsl2795hf 27in crt. Im having trouble finding much info about this tv, anyone have any specs for it?? I got it from my brother a year ago when he moved and bought a bigger lcd and he didn't have the manual or anything.
thanks

OK, I'm in Australia where things are a bit different but I've got a Loewe high def LCD TV and both my separate free to air digital tuner and my DVD player offer rescaling from standard def PAL (576i) to 720p and 1080i. My TV has a native resolution of 1366 x 768 so if I allow my source to upscale things to 720p The TV is still going to have to do another rescale from 720 to 768 anyway before it can display the picture.What I found was that I'm better going with straight standard def output from both the tuner and the DVD and letting the TV do all of the scaling in a single hit. I definitely get better results with only 1 scaling operation than I do when some scaling occurs in the source component and some in the TV.
I think it would be a much more interesting comparison if my sources could rescale to the TVs standard definition of 1366 x 768 so there was only one rescaling operation and the choice became whether to do that at source or at display. Then the question would depend simply on which device did the best rescaling.
Since your TV is 1080i and your cable box can output 1080i, that's the position you're in. The answer is simply going to depend on which of the 2 can do the best conversion from 480i to 1080i. The only answer that makes sense is to try it both ways and see which you prefer.

Another thing, since crt doesnt have a "native resolution" like an LCD shouldnt the scaling have less of an effect on the picture quality?
let you set your specific scaling requirement (i.e., 768). But some of them are pricey!Terry
I know there are scalers and upconverters around but the TV does a damn good job upscaling standard definition inputs. I really can't see it as cost effective to add another box to my mix.I was merely commenting on the issue of letting a source device do the upscaling vs the display doing it, and the associated problem of whether or not letting the source upscale will result in 2 upscale operations with the second one being required at the display end.
To summarise, I was saying that I think it's always better to run with only one upscaling process rather than letting the source and the display do some upscaling each. When you have the option of the display doing it all, or the source doing it all, it simply boils down to which one does it better.

awareness of watching out for "2 upscale operations".I'm trying to decide between a reasonably priced 720p plasma and a much more expensive 1080p plasma or LCD. I didn't really think about the fact that the plasma will be scaling everything, even native 720p HD input, because its a 1366x768 display. If I use an upconverting DVD player (e.g., Oppo 971) to upconvert DVDs, I'll end up with 2 scaling operations. Not good, as you pointed out.
Terry
Im not sure what kinda of scaling my tv does. its an older model Samsung tsl2795hf crt hdtv. It upsamples all SD to 480p and will display 1080i. I dont have the model or any specs for this tv so i really dont know much about it. i got it for free from my brother when he got a new LCD tv. I cant seem to find much about it onnline either. Anyone know anything about this model???
Hi Frank.I wish I could be more help but I've generally found that the easiest way to set these things up is to keep trying it with different settings and see what works best. Not a very elegant solution to be sure, but it works. The nice thing is that there's no way to do any damage. Everything's reversable so if something looks terrible, just reset everything to default.
