EDTV/HDTV Questions List of Categories
Page 1 Page 2 Page 3 Page 4 Page 5 Page 6
- I have a TH-42PD25UP and my cable company (Adelphia) offers HD cable, with a cable box that has (component) and (HDMI) connections.The older cable boxes only offer (composite) & (S-video.) My questions are #1 - will my TV display the HD channels? #2 is it worth getting the newer box for the better connections for the other digital channels that are not in HD? It is only a $6 increase a month.
- I feel a bit confused. I feel confident about the differences between EDTV/HDTV (thanks to you). However, is it true that even a "true HDTV" 1024 X 768 cannot display every pixel of 720p? I remember seeing this on CNET's description of HDTV. If this is right, how can it be considered a "true HDTV"???
- I mistakenly purchased Digital Video Essentials but I have a ED plasma. I've read on your site that DVE is for HDTVs. Is it correct then that I will not be able to calibrate my EDTV with DVE? Or is it just that there are more features on DVE that I will not be able to use when calibrating my EDTV? Thanks.
- I have an EDTV plasma with a SD set-top from my cableco. Currently I am using a receiver to do the video- and audio- selection switching (the video comes via the s-video). When I upgrade to an HD-capable set-top, is it possible still use the S-video i/o in the receiver to do the switching, or will I have to run cables directly from the HD set-top to the EDTV? Another way to ask the question I think is whether a 1080i channel coming into the set-top will be downconverted to 480p then output to the s-video then thru the receiver and into my TV? Or is it better to bring the component video into the TV and allow it to do the downconversion to EDTV? If I have to go direct -- this means using the receiver to select the audio and tv to select video -- is there any other way to do this?
- I going to buy a plasma (42"). But I need to know if I have standard cable will EDTV look as Good or better than a standard tube TV, or do I need HDTV with standard cable to get a good picture.
- A 853x480 EDTV is best for viewing 480p DVD than a 1024x1024 or 1380X768 HDTV. But since EDTV will soon be replaced by HDTV, can we expect that the built-in scalers of the Plasmas will be as good as those on the new DVD players, if we don't want to replace a standard 480 DVD player for now?
- In an "old" meets "new" technological scenario, some manufacturers are now putting HDMI connections on CRT rear projection televisions. The audio benefits of this should be clear. What type of video enhancement (if any) will this produce on these televisions as opposed to "fixed pixel" devices such as LCD, Plasma, etc...?
- Would anyone please have some information on a Sanyo PDP42H2W Plasma. It appears to have most of the functions of a typical plasma and is much more affordable. Please advise if I should stay away from Sanyo products. Thank you in advance for your assistance. Mike
- As you have mentioned EDTV's HD signals are converted to 480. Can you get the same HD conversion with a non plasma tv? Is there any value in buying the 42inch plasma TV?
- We have a 2 year old Panasonic EDTV Plasma with standard cable and it delivers an excellent picture. Will it benefit us to have the HDTV signal brought to our house or does the ED already produce the picture the best it can get?

I would upgrade to the newer box with the component and HDMI connections, they are far superior to the S-video and composite. Your cable company is the only one who answer the last question of your cost per month.

Technically speaking, HDTV playback would require a tv with native resolutions of 1280 x 720p or 1920 x 1080i/p without any scaling. There will be some scaling on a TV that is not native to one of these resolutions. The 1024x768 resolution is an accept industry standard for HDTV and there will be some scaling of the image. We are all anxiously waiting for the day of economical digital displays native to 1920x1080p.

"Digital Video Essentials" is often referred to as just Video Essentials. One does not have to have an HDTV to take advantage of the DVD. There are two versions, one is on a DVD that will support up to 480p which is perfect for standard analog and EDTVs. The other version is designed for HDTV which is on a D-VHS tape. That is currently the only media that can easily support HDTV resolutions. I am aware of WM9 and various competing DVD blue ray formats but, those are not readily available to the public for easy use. One with an HDTV without a D-VHS player can still take advantage of the DVD version.

A S-video cable cannot support a resolution of 480p, you will need to switch to component cables to handle the 480p signal. You can go through a receiver if it has component inputs and outputs.

An EDTV is the best resolution for standard definition cable. I would suggest upgrading to digital cable over analog for a better picture. If you plan to subscribe to HDTV, I would purchase an HDTV plasma.

I believe you have some incorrect information. HDTV is the higher standard video resolution at 720p and 1080i. HDTV plasmas already have built-in scalers to improve the image of the lower resolution signals, such as DVD at 480p. However, you may find some outboard scalers to perform better than in the plasma tv.

That is a very interesting question. HDMI is most beneficial for digital display technology. The benefit for the fixed panels is not going through D/A convertors at both ends of the cable. The signal will remain digital bits throughout the transmission. The only video benefit I can think of in respect to being on a CRT base display is that it eliminates one of the D/A conversions at the source.

I have not been very impressed by the Sanyo line of plasmas. Price is typically a good indicator of quality. Not 100% of the time but it works most of the time.

Without more information, you question is difficult to answer without generalizations. A non plasma tv, could be an LCD, DLP, CRT, LCOS, etc. Pending the technology and features, what it will do with an HD signal with be greatly dependant upon the TV itself. In my eyes, the Plasmas offer the best picture available.

An HDTV signal will only offer minimal improvement to the picture quality.
