The document "Standard video res.svg" implies that PAL and NTSC standard def have different aspect ratios, a common mistake among people who haven't realised the pixels aren't square in either format. Or am I missing something?
Are there different resolutions with hdtv as with sdtv (PAL/ NTSC), or is there one standard resolution/ refreshrate worldwide? If so, it would be a huge advantage for developers of videogames that do not have consider different resolutions/rfr when porting for another market. Also, regarding movies, there'd be no more PAL-speed up, right? —The preceding unsigned comment was added by 84.129.179.117 ( talk • contribs) .
"Some broadcasters also plan to use MPEG-4. Some German broadcasters already use MPEG-4 together with DVB-S2 (ProSieben, Sat1 and Three Premiere Channels). The recommended receiver is Humax PR-HD 1000, but others are announced as well as PCI cards."
-This seems dated and/or a sneaky advertisement. Can anyone confirm that these broadcasters indeed recommend this specific receiver?
"...there are political and business considerations. The mainland Chinese government will likely want to be able to jam TV signals from Hong Kong, so that Chinese citizens near the border cannot receive uncensored content from Hong Kong. Currently, analog TV signals from Hong Kong are delayed a few seconds before being relayed inland, such that content on banned topics such as Falun Gong and the Tiananmen Square Protests of 1989 can be blocked."
-Although China does jam TV signals from Hong Kong to prevent some baaned topics to be on the air, I think this paragraph is unneccsary for the topic of HDTV.
"By the same token, Hong Kong broadcasters are keen to use whichever standard China adopts, since doing so would allow them to transmit into the lucrative Southern China market and would lessen the need for costly format conversion."
-This paragraph shows the real situation in Hong Kong, if the citizens in China really wanted to watch unjammed Hong Kong signals, they may buy them a own set of reciever.

1. please note that ATSC specs call for DD for the audio encoding. now DD does NOT say how many channels SHOULD be present. just how the audio is encoded into the stream. you can have a one channel DD stream. 5.1 is just what everyone knows about. of course a program can be upconverted by a provider as an HD stream while just including 2 channels of audio. and that is a common use for many older films and programs (including tv programs) from our pasts.
2. under the non engineering section, again ATSC specs call for 16x9 ratio for all HD programs. if a program is HD, then it must be in that ratio. the entry says "MOST HD and film programs..."
I wonder if somebody would consider covering the 1366 x 768 resolution? As most HDTVs in UK (and possibly the rest of Europe) seem to have a native resolution of 1366 x 768. For instance, is it known whether HDTV movies authored for this region will be native 1366 x 768, or will the TVs have to upscale from 720p to 768p? Thanks, TimTim 14:12, 6 June 2006 (UTC)
768p is not part of any HDTV standard, so yes, all tv sets will upscale (720p) or downscale (1080i/p) content to the native resolution of these displays. I don't know the details about why this bizarre resolution (1366x768) is being used by most tv manufacturers. Some people say it's just to build computer & tv displays simultaneously (1366 is 1.78 times 768). Thewikipedian 18:23, 18 June 2006 (UTC)
Some information about 1366 x 768 would be appreciated, I have recently brought a JVC LCD TV with this resolution and would like to know as much about this as I can.
This 1366x786 resolution isn't just native (no pun intended :) ) to Europe—a lot of the US market HDTVs appear to have this resolution as well. What's also quite odd, IMO, is that this article makes no mention of this whatsoever. It seems noteworthy to me, especially considering the ramifications this ought to have for HDTV image quality (because of native resolution)—the supposed raison d'être for HDTVs in the first place. This article, without mentioning this, seems rather lacking if it's as common as Sony's US HDTV Flat Panel 32" to 40" page (to name one) suggests. 8 of the 12 HDTVs there are 1366x768, and Sony's not an obscure or cheap brand.

good afternoon, would like to know if the projector Sanyo Z4 supports technology HDTV. e which its loss of quality?
to answer in the email hugo_balieiro@hotmail.com debtor
The Sanyo Z4 would certainly support this, I have a friend who has a Z3 and this has HDMI and this does 720p and 1080i, the Z4 probably doesn't do 1080p though, but you could find this out very easily. One good site is projectorcentral.com
I created an archive of older discussions. I also split some sections (pre-recorded media and compression) of HDTV into separate wikis, as the main page was getting too long (>40 KB). Thewikipedian 18:44, 20 June 2006 (UTC)
I think this article could do with some discussion about what bitrates and bandwidth are generally used for HD broadcasts and storage on media - I couldn't find anything significant on the subject anyway. Or is it discussed in other articles? -- Zilog Jones 15:52, 9 August 2006 (UTC)
In the first comparison of resolutions diagram "Standard resolutions" 720 x 480 DV NTSC/VGA, but VGA is 640 x 480. The later diagram "Digital video resolutions" below Exernal Links correctly shows VGA as 640 x 480. I don't know how to edit the .svg diagram.
There seems to be a little confusion about PAL and NTSC resolutions; I think that section could probably do with a little clarification, especially as there appear to be several NTSC and PAL resolutions. (See [2]]) TimTim 19:47, 3 September 2006 (UTC)

There needs to be a section discussing the long-term impact that HDTV may (or likely will) have on non-HD television productions. (Basically, as I understand it, pretty well everything produced before the late 1990s). The original Star Trek series, for example, in order to be released in HDTV has had to undergo major alterations, with new special effects and even music replacing what was originally made in the 1960s (this is going over like a lead balloon with a lot of people, while the younger folks who just don't care are jumping for joy). The implications are clear that many classic shows of the past, from I Love Lucy, The Honeymooners, The Twilight Zone, Doctor Who, and many others may either have to disappear or be greatly altered in order to be viewable in the HDTV format. Unfortunately all I know I what I'm reading about Trek; for me to add such material to the article would be uncited and probably considered POV. Has anyone come across any articles or other discussion about what HDTV is going to do to 50-60 years of television history? Or like the TOS fans who seem attracted by the newest shiny thing, are people just going to not care? 23skidoo 13:45, 12 September 2006 (UTC)
Way back when widescreen broadcasting started (TVs started coming out in 1992, and Channel4 were broadcasting some PALPlus around 10 years ago in the UK) I just wish they'd agreed on a full 2.35:1. I'm sick of explaining to people why their widescreen TVs still have borders when showing some DVDs! I don't want to have to build a mega home cinema with anamorphic lens to do the 2.35:1 properly! —The preceding unsigned comment was added by 81.86.138.193 ( talk) 01:10, 11 January 2007 (UTC).
The contemporary systems sections has been merged with List of digital television deployments by country. High-definition television in Europe will be merged with Digital television in Europe, but it still needs some cleanup, as HDTV and digital SDTV are really messed up Thewikipedian 10:58, 15 September 2006 (UTC)
I don't really see how point #1 can be considered an advantage. Things like pixellation (which I see all the time on digital cable) and still pictures is in many respects worse than snowy or lined images. I suggest moving this point elsewhere in the article as it kinda shoots the topic in the foot where it is now. 23skidoo 19:50, 19 September 2006 (UTC)
I know what you mean, I was thinking it could be added to the "Comparison to SDTV" maybe something after the picture comparison like:
In addition to the improved picture quallity, although most newer TVs are also compatible with digital broadcasting, all commercial HD is digital, so the signal will either deliver an excellent picture, a picture with noticeable pixelation, a series of still pictures, or no picture at all. The system cannot produce a snowy or washed out image from a weak signal, effects from signal interference, such as herringbone patterns, or vertical rolling.
Maybe not the best place but I'd like it kept somewhere in the article becuase I think it's worth mentioning. - Doc711 15:12, 14 October 2006 (UTC)
Edited to show the disadvantages of this, as well as the advantages.
If you have a 720p screen, will video recorded as 1080i still appear the same as on a 1080i screen? (Besides interlacing and progressive things... I mean the actual picture quality. Regardless of the correct answer, this should be metioned in the article. aido2002 20:31, 26 September 2006 (UTC)
The article states "In addition, the technical standards for broadcasting HDTV are also able to handle 16:9 aspect ratio pictures without using letterboxing, thus further increasing the effective resolution for such content". This seems to imply that SDTV feeds only support widescreen through letterboxing, as opposed to anamorphic display. This is incorrect - digital SDTV widescreen broadcasting is usually anamorphic in the UK at least, with letterboxing extremely uncommon. Cpc464 09:40, 16 October 2006 (UTC)
Just a nice converstaiton about HDTV usage by Wikipedia members. I have good news and bad news. Good: I have HDTV. Bad: I only have 720P.-- BigMac1212 16:54, 19 October 2006 (UTC)
HDTV history and old models?
I would also like to see more on the disadvantages of HDTV over standard television, and what types of HDTV sets are available(specifically, are there CRT HDTV sets? I can't find any info on that one way or another)
Hi,
I am dismayed to see that vandalism repair has resulted in collateral damage in the External Links section of this page. I posted a link to http://www.hdtvexpert.co.uk in good faith, as this is a good source of reference for the consumer in the UK HDTV market (this really is a new and emerging market, as HD broadcast and other media is still in its infancy here). I can vouch that this site does not carry any pop-up, pop-under or other browser-unfriendly/hi-jacking script. The content is maintained frequently as a source of news etc. for consumers in the United Kingdom.
Could you please re-instate this link, or at least provide me with an explanation as to why you think this does not make a useful contribution to your visitors.
Kind regards,
Tim
There are two errors in the aforementioned table in the column DVB-T! In the row outer interleaver: according to the DVB-T standard a convolutional interleaver (interleaver depth I=12, number of shift registers M=17 and register depth j=one symbol or one byte) is used for outer interleaving, not a block interlever. In the row inner interleaver: inner interleaver consists of two levels: bitwise interleaver in the first level and symbolinterleaver in the second. So there are no use of any frequency functions or so on. nmo 83.135.4.183 16:28, 6 November 2006 (UTC)
I'm looking for an HD solution to tide me over while the DVD format wars are fought.
Perhaps this article could comment on which current HD format looks best when watching non-HD DVDs?
Thanks!
Well I have an HD set that does 720p and upconverts (or something) to 1080i. DVD movies in general look just mediocre. DVDs that are "enhanced for HD TVs" look a bit better, and usually are in 16:9 format. But when comparing a DVD movie to an HD channel that happens to be showing the same movie, the difference is very clear. For example I had watched most of Gus's "Last Days" movie in HD on HBO, but missed part of it, so I decided to rent it a few days later. When I finally got around to watching it, by chance HBO HD was showing it again, so I switched back and forth between the two, and although the DVD was "enhanced for HD TVs," the quailty was much better on the HBO broadcast. So I guess my answer is, if you don't have an HD set, and aren't ready to jump on the Blu-ray or HD DVD bandwagon yet, don't worry, because the quality of a DVD on an HD set isn't as great as some might think. 24.22.56.137 04:19, 6 December 2006 (UTC)Jordan
There are a couple of botched rvs on this page because I got confused about what user added what and removed what. Please disregard and excuse my foolishness. — David Spalding Talk/ Contribs 15:31, 3 December 2006 (UTC)
Two questions:
First, I have a friend who claims that personal computers have been displaying "HD quality" for 10 plus years now. But I don't think he's correct on that one. He refers to the resolution 1280x720, and says that since computers have been able to support this resolution for years, that proves that they have been able to display HD for years now. That's really his only talking point, and when I bring up 720p or 1080i, that's when the conversation gets confusing, mostly cause both of us have limited knowledge about how you can compare a TVs resolution and/or encoding.
Secondly, since certain companies are now selling "HD" computer monitors (Apple comes to mind), what does that exactly mean? Of course my friend the computer guy would say it's just a gimick, since computers have been able to do HD for years... So what is the difference between a normal LCD computer monitor compared to an "HD" model? 24.22.56.137 04:06, 6 December 2006 (UTC)Jordan
I think this page needs a source for the 10% penetration number given in the article intro. Theflyingorc 21:05, 6 December 2006 (UTC)
So let me get this straightened out, because the article doesn't come out and say it. Or if it does it's somewhere amongst the technical information and I just didn't catch it. Anyway if I purchase an HD television set will normal television (4:3 ratio) appear correctly proportioned, or will it be zoomed in with the tops cut off, or will it be squeezed into the HD television proportions? Natjo1986 06:09, 22 January 2007 (UTC)
HD is nothing more then a marketing term for a digital signal. It's meant to limit the customer and make them think they are getting something better when there not. The term should be done away with as it's directly related to DRM restrictions. Please state a dissension in the article. DRM has brought nothing but confusion to the marketplace as it's not creating mass confusion wind anger over the DRM imposed in Microsoft Windows products.
Enough about the science! What about a simple history charting its invention and proliferation? its early introduction? what was the first show ever broadcast in (what's currently known as) hdtv? early reluctance to buy the sets? the requirement to buy those stupid hdtv receiver boxes? which started broadcasting hdtv first: nbc or abc? when the switch was or wasn't made from 720 to 1080? i don't know any of these answers.

HD is nothing more then a marketing term for a digital signal. It's meant to limit the customer and make them think they are getting something better when there not. The term should be done away with as it's directly related to DRM restrictions. Please state a dissension in the article. DRM has brought nothing but confusion to the marketplace as it's not creating mass confusion wind anger over the DRM imposed in Microsoft Windows products.
Enough about the science! What about a simple history charting its invention and proliferation? its early introduction? what was the first show ever broadcast in (what's currently known as) hdtv? early reluctance to buy the sets? the requirement to buy those stupid hdtv receiver boxes? which started broadcasting hdtv first: nbc or abc? when the switch was or wasn't made from 720 to 1080? i don't know any of these answers.
