i dont know if this is the proper forum to post this question.. please move if this is the wrong place.
after reading different articles on this issue, i am getting extremely confused. do we need an hdtv or digital tv? i currently have a sdtv, which was purchased in 2005. when the usa will switch to hd in feb 2009, would i need to get another tv or continue to use what i have now? i only watch news from over-the-air channel, and watch directv satellite all the time. please help! thx!

You could get a converter in order to use your sdtv the government will give voucher of 40$ if you ask.As for the other question hdtv is fine.
-
Are you sure you've got your facts straight? The only "switch off" that I'm aware of (at least here in Australia) is that of the old ANALOGUE transmissions...the stations will still be transmitting both SD and HD channels after that.

You can get a digital converter box to continue to use your existing TV. This is a link to a thread about the discount coupons for the converter boxes: https://forum.videohelp.com/topic343391.html
In the US full-power television stations cease analog broadcasting after February 17, 2009. Cable channels and other sources may still have analog TV format available after that date. -
yeah, i know that there are coupons for a converter box. what im confused is... do i need a hdtv or just a digital tv? i think mine (sdtv) is already digital, but not hd.

You need a HDTV to watch HD in all it's glory. If you just have a standard CRT or LCD TV and are happy with it for the moment then all you need is a set top box (SD or HD) to bring in the broadcasts. If your TV already has a digital tuner (and not all LCD/Plasma screens do) then you won't have to change anything.

Your confusion is with the anagrams. TV stations have historically been broadcast in analogue transmissions - these are now moving over to digital transmissions instead (still same stations & programmes but with some additional stations too). The older TVs will need some sort of coverter in order to watch the digital transmissions. Newer TVs will have a sticker indicating they can be used to watch digital stations without the need for an additional converter (at least they do here in the UK).
SD and HD refer to something else - they size of the picture being shown. Standard definition TV programmes in the US are made up of around 480 horizontal lines. High definition programmes are made up of either 720 or 1080 horizontal lines - this allows for the much greater clarity and level of detail you can see.
Here in the UK all digital free-to-air broadcasts are in SD - from reading this forum I gather in the US things aren't so simple: whilst the majority of digital stuff will be in SD, depending on where you live you may also be able to get TV stations in HD. If you live in such an area then currently you will not be able to view these HD channels on your SD television, but will still be able to watch all the other stuff. -
You can get two $40 coupons no questions asked from the US Government at the following link:
https://www.dtv2009.gov/
Quantities are limited. Act now. It takes about two min. -
3390 - Over the air will stop working for you on Feb. 17, 2009 without a converter box. I believe that your satellite TV will be OK, but you might check with your provider. You don't HAVE to buy an HDTV. A converter box, if you need one, will convert the digital broadcasts to analog so your SDTV will still work.

The "government certified" ATSC tuners listed on the coupon site are very basic. The first example is this DTT900 LG/Zenith tuner.
http://www.zenith.com/dtv/dtt900.html
It will tune any of the SD or HD broadcasts but downconvert them to composite NTSC with analog stereo audio or NTSC RF Channel 3 or 4 over coax.
The government coupons may be limited to this very basic class of ATSC tuners.
Better digital tuners would include
- S-Video or component analog (SD/HD) output connections
- DVI-D or HDMI digital out (with HDCP encryption)
- Dolby Digital AC-3 audio over S/PDIF connectors
- 480i, 480p, 720p or 1080i output settings.
- Data access modes
The government ATSC certified tuner may be adequate for a 1990's analog set (addition of S-Video would be nice), but for "HD Ready" sets, an HD out capable tuner should be used. There will be many new models to choose from in the coming months. Current models and reviews are listed at the AVS Forum.

btw.. this is off topic, but just wondering if anyone may know the reason and fix for it. i used to have the basic satellite receiver for directv and was able to watch all over-the-air channels (except channel 2 since channel 3 is for satellite). ever since i upgraded to the r15, every over-the-air channels are snow. i tried to turn off the satellite receiver, but still doesnt fix the problem. the only channel i can watch (with ok clarity) is channel 7 even with the satellite receiver left on. -

Of course this all only applies to those still using an antenna. Many of the people confused/complaining are using cable/SAT, in which case it is all irrelevant.

Analogue has nearly nothing to do with HDTV.
analogue > digital is inevitable.*** Now that you have read me, do some other things. *** -
Most of the confusion involves these items:
(1) That digital tv will somehow look better than current analog TV.
FALSE! It won't. In some cases, the compression will make it look worse. You exchange analog noise for digital blocks. Oh goody.
(2) That it affects everybody.
FALSE! If you use cable or satellite, no effect to you. Only if you use antenna. I'm so far away from a transmitter, that I could use an antenna (analog or digital) if I wanted to. I either watch cable or DVDs.
(3) That is has anything to do with HDTV.
FALSE! Digital television (DTV) comes in standard and high definition.
Weird enough the "SD" stands for "standard definition" and "HD" stands for "high definition", so if "DTV" means "digital television", then shouldn't our abbreviations be HDDTV and SDDTV?
Stores like Best Buy are full of high school and college dumbshits, many of whom insist an HDTV is required by 2009.Want my help? Ask here! (not via PM!)

* The subject is with respect to HDTV broadcast, and not HD as in commerical type sources,
(ie, movies) etc.
...
(1) That digital tv will somehow look better than current analog TV.

from Satellite to begin with, way back when. And now that HDTV is on the move, I've already
seen the quality of this new medium and all I can say is that it too is very disapoiting.. you get
the same nonsense you do with Satellite -- DCT errors; Macro blocks; Pixalations; more..
and on top of that, they purposely 'degrade' the tv program.. either by reducing the bitrate or
squeezing more channels on the pipes or whatever. Either way, the end result is always reduced
quality.
* true in the sense of what they are and have been doing to the HD content, as explained above
and below.
The only good thing out of this medium is the Resolution and (supposively) more detail. But after
reallzing the above nonsense that goes into this, you are basically left an a higher quality analog source..,
well, maybe not.
Now, I'm a quality buff. Many of you know this of me. I strive and research the best methods to
produce maximum quality of whatever my source is for when I am transfering it to (ultimately) dvd.
Course, analog has its loooong bouts with its weakness.. noise. But I would rather put up with that
(if it were broadcasted HD 'wise as analog) for analog reception than HDTV. HDTV -- It's insulting.
Like a slap in the face, imho. And to this day, I do just that.. I put up with analog cable tv. Why ?
Because it would seem that the bitrate does not go through the nonense laid out ealier above. So,
all you are left with is the noise and the limits of analog sampling or whatever.
( I'm wondering if they will outputing HD broadcasts over analog cable. I mean, it looks like they are
doing this, but reducing it to SD 'like specs. I could be wrong. But, I think I would be happy with that
type as an alternative to HD, in the so called, raw.
But, here is something to ponder..
Our area when through a major cable re-installation some three years ago. The purpose was to get
ready for 'digital' and provide digital cable over analog, and you have to have a digital cable box (theirs)
capable of descrambling the channels. The aim or drive of that medium (when asked) was that it
provided superior 'digital' picture quality. Course, I knew even then, that it was just balonee.
But road the wave as the gentlemen was stalling the new cables through the building. (I'm getting
to my point now)
The cable provider (supposively) provides both Analog and Digital cable tv. You have the option of
either one. But, if you with digital, then you have to have their box to view it. I choose to have
Analog. SO, I didn't need anything but my tv set. So, I use my vcr and tv, and I'm happy. Really.
But, I've seen both, (digital and analog) and they both look pretty similar, except that the digital
doesn't have any (analog) noise. But, the catch here, is that BOTH video sources are being sent
through the same cable wires.
So, I'm wondering if HD will follow something similar. Either in is true HD glory or modified, perhaps
SD or xSD or something. I don't know. I'm just theorizing at the moment.)
Anyways..
Look at the great TV series, 'LOST'. What a fantastic series. I LOVE this show, and love all the
casts, and so much more. But watch it in HD and you are instaulted by all (downgraded) degrading
quality of the HD. And they also apply the tipicle modified telecine system (I have lately been
terming it as, TEC (Time Expansion/Compression)) this source, too.. so you can't get a proper and
clean IVTC out of this series. This is just one example of the nonense with HD.
My best guestimate is that broadcast providers and their HD content will vary their bitrate scheme,
one to another. So, for instance, while in one city the bitrate is 19MB, in another, it might be,
15MB, and so on.. So some people may have slightely better HD (recorded) versions than others.
And when you are locked in a city with a given bitrate scheme, you are 'locked' into that scheme
(quality level) for ever, unless they change or something. But just remember, that with all antenna
signals, location of the TV channel will also be different. That means, that while your ABC is using
a lower quality scheme, you NBC or PBS or whatever channel you are able to receive for your given
area, may be higher quality. And then there is the other idium, where they will give you reduced
quality at a certain time and then higher quality, later. And this too, will vary. Ultimately, all this
will all vary from person to person. I've already seen this in the (ABC) tv series, 'LOST', and
compared it with someone else 'es, last year, though I no longer have the sources -- I didn't think
to keep it at the time, and I should have -- and all this makes me puke.
What we really should do (at least it would provide something interesting) is gather a few members
together and record a few of the popular HD channels and post them up so that we can get a
'guage' at the different quality apsects. This would prove interesting, indeed.
EDIT: one thing I want to add is that I was not saying that HD or HDTV is worse than analog
cable tv, but that it is not all that what it has been so hyped about. It is undoubtedbly better
quality, but that for its medium in relatation to older medium like digital cable/satellite, they
will always taint or reduce or hinder or jsut flat out *NOT* release the high quality that this
supposively hyped new standard is capable of. And, for the time being, I prefer to just watch
my analog cable, though mostly because I only have a few HD channels, if any.

I sympathize with you vhelp. I attended the NAB conventions when Sony, etc. were demonstrating their early full bandwidth HDTV systems. Stunning to say the least.
The good news is that the limiting factor is not the HDTV itself, but rather the source quality. There is a lot of room for improvement, and things keep getting better.
Keep in mind how soft and noisy the early B+W and then Color SDTV broadcasts were. Things kept getting better. Farnsworth deserves a lot of credit for designing a TV format that lasted so long and improved so much.Life is better when you focus on the signals instead of the noise. -
The biggest problem with our digital cable is the huge amount of temporal filtering they do on analog sources. Apply VirtualDub's Temporal Smoother filter at the 8 setting and you'll get an idea how bad our digital cable is. Macroblocking is a problem on some of the digital sourced channels.

Many issues raised. Too many to respond all at once.

Broadcast NTSC also suffers ghosting and RF harmonic noise that aren't issues with digital broadcasting.
Digital ATSC (MPeg2) quality depends on bitrate (transmission issue) and maintaining minimal RF signal to noise (distance and antenna issue).
Despite what the cable companies said in the 80's, "Digital Cable" was always about forcing 6 to 12 channels into the space of one 6MHz analog channel. It was never about video quality. People assumed "digital" gave better quality (based on audio CD experience) so cable advertised to this belief as did Direct TV and Dish who were delivering even higher compression for SD.
ATSC SD quality can be as high as DVD but so far nobody is delivering quality 480p in wide or 4:3, Instead they offer 480i at bitrates equal to or slightly above cable. PBS gets reasonable daytime results with 4-5 subchannels averaging 3.80-4.75 Mb/s. Statistical multiplexing can give near DVD quality for 4 subchannels within 19Mb/s.
Networks and local stations have ample opportunities to screw up quality. Small market stations just can't yet afford high end upscalers. Next generation equipment will be within price range for mid market stations.Recommends: Kiva.org - Loans that change lives.
