That's what I thought.

h this is a geek fest! i have a 27" with a comb filter and i think i am living large! when i went to my aunt's they have a huge HD tv... and the game looked great...but it did not help the cowboys win the game!

According to the FCC to be considered HD you hacve to be 720. Anything more is high quality HD. HDNET Movies is 1080i The term True HD is a Sony marking gimmick they invented for the Playstation 3. For more info on HD TV go to http://en.wikipedia.org/w...ted_States

Answer me this: When I watch Purple Rain Special Edition DVD on my 1080i TV why is that "less" high definition than HDNET's broadcast? What kind of the source are they using to broadcast from?

sorry to interrupt the A/V club chat this thread has become, but i promised something earlier...



i promised, so i gotta deliver. carry on.

skywalker said:

Easy, the video quality on the DVD's are lower res than 1080 pixels, therefore it's like in Photoshop when you blow up a 72dpi image to 300dpi, it looks a bit shitty cause it's adding resolution but there is no detail there. On a normal/standard/tube tv the screen res is 72dpi, so the dvd looks clear cause is is essentially resizing the image down to 72dpi. You can take detail out and keep the quality but you can't add it in. Broadcast Hi Def will be broadcast at 1080 dpi so it will look crystal clear on a 1080 screen cause there is no blowing up of the image to fit the res of the display screen.

The DVD format has 480 lines of resolution, and as far as the technical specifications go this is not considered High Definition.

The broadcast on HDNET will have 1080 lines of resolution.

You can watch both on your 1080i TV, but the DVD will have to be scaled/upconverted to play back on the TV. This process can't add more detail that isn't on the DVD, but is necessary to make the picture fill your TV screen.

Thanks. So what size TV do you have to have to even really notice? Some reports I've read say you need 50 or more to even see it. True?

Again, what do they use for "source" material?

Also---
Question: If I watch "lost" on HD Broadcast-then I buy it on DVD the DVD looks the same quality to me on my 1080i TV. Why is that?



ps. thanks for the razor bumps, girl, that IS sexy

they scurred the HELL outta me when i first watched the SE dvd, man.

skywalker said:

I've heard the same. I found the following website to be informative, especially the first chart that shows what combinations of TV size and viewing distance make it possible to see the difference between different resolutions.

That is a very good question... and I don't know the answer. If HDNET was using the DVD as the source (hypothetical example), then all else being equal it could not look any better than the DVD even though it's coming over as a "1080i" signal.

Hopefully they have a source that allows for better-than-DVD quality for the broadcast, but as someone else mentioned, the original master may limit how good the 1080i broadcast will be. I'm not sure how much detail can be captured in a transfer from the film that was originally used.

will this be showing in Ontario, cananda???

I hope some of you all are kidding. Or blonde...

1. Purple Rain was shot on 35mm film... better than HD.

2. there are 1080 broadcasts in the USA, I just listed some facts in an earlier post.

3. You make a DVD from the (beyond HD resolution) film print or negative... so you are basically downsizing an HD master to the tiny DVD format.


come on you all...

or are you all kidding? I'm slow on sarcasm.

check the graphic posted earlier.

you're being sarcastic, right?

what is this "SE DVD" format being typed up in this thread? there is no such thing... I professionally create educational videos/animations ranging from ntsc, to dvd, to hi def, to 70mm, to imax size formats... there is no SE DVD format... by special they mean the content, not the format.

Just look at this graphic I posted... it illustrates exactly what the differences are. And for those who don't know... your dvd's are the smallest picture size depicted! DVD=NTSC (720x480)

Hey dude, I think the SE DVD people are talking about is just the "Purple Rain Special Edition DVD" as opposed to the "Purple Rain DVD" which when released had no special features and was 4:3 frame. They're not saying it's a damn format, just the remastered dvd release.

ufoclub said:

For the last time (hopefully ) you posted info on broadcasts in 1080i NOT 1080p. There's a difference.

Nobody's talking about an SE DVD format - they're talking about the SPECIAL EDITION DVD of Purple Rain.

And the broadcast looked good, not great. The problem is that there's grain inherent to the film stock they used and it is magnified in the transition to digital.

Handclapsfingasnapz said:

Is that HD? ..he still looks good.

Hey Urkel--not everyone speak tech talk so please don't be condescending or pretend that HD info is common knowledge.



Yes, but unless they are using an original 35mm print as the source for the broadcast that is meaningless right? The question remains--what are they using for a source for the broadcast. Purple Rain SE DVD? An HD/BluRay equivalent?



There are NO 1080P broadcasts. Note the "P". If they are using a source that is equivalent to bluRay it's not going to matter--it cannot be broadcast in 1080P.



Right. I get that. However, again I ask the question what is HDnet using for a source? If they are using the film print for the broadcast what are they using? How can you be sure that they are not just broadcasting the DVD-equivalent?

When a movie is brought in to convert to video (if it is originally shot on film) the 35mm copy is scanned to create a hidef digital master. This digital master is then either resized to create an NTSC master. The master is most likely in a lossless format and put to tape for an archive.

A high quality DVD is still akin to basically creating a small moving jpg of this master.

HDnet cannot broadcast a dvd and fool anyone with a HD tv. The difference in quality is obvious.

"HDNet is the first national television network broadcasting all of its programming in 1080i HD, the highest-quality format of high-definition television (HDTV)."

1080i vs 1080p is still the same image resolution on the tv. "i" just throws it on there in two steps, quicker than you can notice.

Blueray or HD DVD are forms of storage of an HD picture (or gigs of info), a way to put them on one small disc, so that only applies to discs you rent or buy. they still hold the same size HD pic of 1929x1080.

..I have a 51' HD compatable TV..but to see shows broadcast in HD I have to buy some box..that's ridiculous..you would think paying $1300 + for a tv, it would have everything with it !

hisfan4ever said:

Thats a good point!!! We are getting FREE HDTV with the digital box for one year...(It came with our new TV) & YES...there really is a difference between regular TV & High definition TV. a HUGE diff!!!
but like you said...ya gotta pay for HDTV

Handclapsfingasnapz said:

Bruh' needed some MAGIC SHAVE!!!

skywalker said:

Regular DVD is not Hi-Def, so if HDnet are using anything other than a film or Hi-Def(1080i) source, then you'll notice it on your HD set. If you have an upconverting DVD player that you watch the SE Purple Rain with, then this may not be as noticable. Actually, as you probably already know, a number of factors can make a big difference in how the picture looks, such as HDMI vs. component cables, your set's scaler and processor, plasma vs. RPTV vs. LCD, etc.

Peace.

hisfan4ever said:

Some sets have the HD tuner built in, but cost used to be a major factor in why sets didn't come with it. Now, it really is a narrow price margin.

If your set has at least component inputs, you can get an HD receiver for under $500.
