Thanks for a great site!
I'm considering an HDTV-ready set, mostly to watch 16:9-480p dvds for now, and I have a couple of questions:
- Much of my viewing for the next few years is likely to be analog (I have 'digital' cable, but mostly still watch analog channels; haven't yet bought the expensive HDTV-capable cable box for the ~5 available HD channels). I've heard that analog signals look worse on a digital set... is this true? I'm often amazed by the clarity of picture on my analog set; is this a step backwards?
- The Toshiba set I'm considering (30HF83) supports 540p instead of 480p. Seems non-standard; is it anything I need to worry about?
Thanks for any help...

pixelized annologe on HDTV
I recently bought a Sony 34 in CRT HD-ready TV. The Normal signal that I get through cable seams a little pixelized, however this issue is not obvious on my old tv, Is there some thing I am missing?
Comment from Admin.
It seems that your new set is doing a good job of displaying the program and also the defects built into it by digital compression in the cable system or elsewhere, even though it may be received as an analog signal. Good quality HD televisions, such as the one you have purchased, display all the fine details that normal NTSC televisions cannot, unfortunately including any and all the noise and artifacts. With a good HD signal, I expect you will see stunning pictures on the television, but the little annoyances on SD signals are not unusual.

I can say from Experience on your original question
"I've heard that analog signals look worse on a digital set... is this true?"
I have Just purchased a 30" Samsung 16:9 HDTV (does 1080i/720p/480p/480i) and have digital Cable (non-HD) and it does somewhat bring the picture quality down, rather the screen is so clear that it brings out the inperfections of analog and SD Digital Cable, Thankfully the TV's picture controls are fully configurable and I am able to dull the sharpness down to make it look good. definitely go with a Wide Screen TV if you plan on spending any serious $$$ as it makes DVD watching much more pleasurable and will make you ready when the industry is fully tranmitting (or mostly) in HD which is always in Widescreen or 16:9 format

Yes, you have it exactly right. 540p and 1080i are the same thing from a display viewpoint. In the case of fixed-format displays such as DLP, LCD or Plasma, which tend to be 720p, it is necessary to convert non-native formats, such as 480p or 1080i, to the format of the display device. Increasingly, displays at 1080p are coming into the market. Only in the case of CRT displays can the display format itself be modified. Thus scan converters are an essential part of any non-CRT TV that will display all the ATSC formats.

Nope... never did get an answer to the 540p thing. From my subsequent research, it seems using 540p means less costly electronics in the set, since they only have to support and calibrate for a single scan rate (maybe the wrong term) for 540 and 1080 lines. Downside is, every source (except, I guess, true 1080i HD) gets scaled in the set, so you're reliant on the quality of their scaler.
That's what I've read, but I don't pretend to really understand what's going on, so I'd still appreciate a comment from one who knows.

Did you ever get an answer to your question "540p instead of 480p. Seems non-standard; is it anything I need to worry about? "

Let me tell yo this, once you get and see true HD channels you will never go back. I have a 47" Panasonic TV 1080i - 480p 16:9 widescreen Bell Expressvu and 20 HD channels (CTV, City, ABC,NBC,CBS, CBC etc and believe me there is no comparison, CBS is the true leader in the big 4 right now for programing watch CSI Miami and you will get the picture also using a Denon 3803 reciever for full digital 5:1 ES, DTS sound in a full home theatre. My moto start with the best and you never have to worry and second guess your decisions.
