What's the model number?

Likely it will accept 1080/24p signals, but doesn't display them at a refresh rate that's an even multiple of 24.

3 times 24 = 72, and thats my refresh rate.

Okay, so you own the one 2006 model that does a proper 24 fps refresh! :)

For whatever interest it may have, my Samsung pn50a450, a 720p set, advertises the ability to accept 1080p/24 signals, and it does. I downloaded the Hulk 1080p trailer and played it. Two lights on my HR20 lit up for the 1080p signal, and the picture looked okay.

Does the same thing on my 32" Samsung 780p, but it doesn't show it in all it's 1080p glory, it's converted to 780p by the TV.

cool..

the page states "DIRECTV now presents select DIRECTV on DEMAND titles in 1080p. And stay tuned as our 1080p library continues to grow."

Where is this "library"? I cannot find it....


My thoughts on this would be that they are working on the "library",but just haven't released it to the public yet.
I've snooped around a bit on DirecTV's site,but nothing is coming up for the "library" at this time.

Couple questions on this,
My new Sony Bravia displayed 1080/24p in the banner, so I suppose it supports 1080/24. In my HRDVR22 is have resolutions 1080i and 1080p and you can test the 1080p but cannot choose it as an output. Is that just there for future use? Is says you cannot choose 1080p from the "format" button. I turned on native and I assume the test trailer outputed at 1080/24p directly from the DVR, and was not changed by the tv itself, but, will ALL content be 1080/24p out of the DVR in the future or will the 1080p output of the DVR be 1080/60p for video content? Also, what happens with the new 120HZ displays? wouldn't that make judder even worse, not better as they claim? :confused:

When you download 1080p content, which for now is only the Hulk test trailer, it will initiate a test of your TV, and if you have a 2007/2008 Sony, it will pass and select 1080p for you, because your TV will support 1080/24p input signals.

I turned on native and I assume the test trailer outputed at 1080/24p directly from the DVR, and was not changed by the tv itself, but, will ALL content be 1080/24p out of the DVR in the future or will the 1080p output of the DVR be 1080/60p for video content?


HD from the various networks is either 720p or 1080i. Those are the formats they send to everyone. No one broadcasts anything in 1080p. Thus, 1080p is limited to downloaded PPV 1080/24p content. Everything else will be 720p or 1080i if Native is ON, and will be converted to whatever resolution the receiver is set to with Native OFF, with 1080i being max.

Also, what happens with the new 120HZ displays? wouldn't that make judder even worse, not better as they claim? :confused:


Judder is caused by trying to display a film source, which is 24 frames per second, on a 60 frame per second TV. 60 isn't evenly divisible by 24, so there is no way to display each film frame for 1/24th of a second, as it is intended to be seen. So, the way it's always been done is to repeat the first film frame 3 times, then the second film frame twice, the third 3 times, the fourth frame twice, and so on. So, the 12 odd-numbered film frames are shown 3 times each, and the 12 even-numbered film frames are shown 2 times each. 3x12=36 2x12=24 36+24=60. This is called a 3:2 cadence, and often called telecine.

But you can see the problem: odd-numbered frames are on the screen for too long (1/20th of a second) and the even-numbered frames aren't displayed for long enough (1/30th of a second). This creates judder, and on bigger, higher-def displays, it is more noticable than in the past.

The solution is for the TV to offer additional refresh rates other than 60 Hz; specifically, a resolution that was an even multiple of 24. And in the last couple of years, TVs have been available with displays that refresh at 48, 72, 96, or 120 Hz, in addition to the standard 60 Hz. At any of those resolutions, 24-frame content can be displayed by repeating each frame the same number of times that the refresh rate is a multiple of 24.

So, a 120 Hz TV should refresh 24p content by repeating each frame 5 times. 5x24=120. Or a 72 Hz TV would repeat each frame 3 times. 3x24=72.
This way, each film frame is displayed for exactly 1/24th of a second, just like in the movie theater. Judder is eliminated.

Note that all current TVs require that any motion stabilizer software, such as Sony's Motion Flow, be DISABLED in order to get proper 24p refresh.

IIP, how many times you already explained the 1080p/24 details ?

Wouldn't be easy to provide URL to your initial posts (not just one !) about this ? ;)
I'm guarantee you - the question will come each week while Dish/DTV still provide such movies.

I know. The problem is that I can never seem to find the right post, so I end up re-typing it all, and each time I tell myself that this is going to be the last time... :lol:

My Samsung 4665F Gets the 1080P signal just fine. Looks great! When I pushed the Hulk trailer play button, the clip started, the two rightmost lights lit on my HR23-700 and when I pushed the TV info button, the info screen showed 1080p at 24hz.

A new thread was started about this in the HD DVR forum a little while ago,but I thought I would post the info in this thread too.
The full length film version (1 hour,53 minutes) of The Incredible Hulk appears to be available in 1080p on channel 1100 at this time.
It is available until 3/31/09.
Purchase price is $4.99.
If interested,go to channel 1100,select High-Def and scroll down the listings.The Hulk in 1080p is listed underneath Hellboy II.

IIP - You seem to be the most knowledgable about this subject. I am in the unfortunate group of folks that purchased a 1080P TV before 24P was introduced into TVs . When I purchased my TV, I knew nothing about 24P and thought I was spending the extra money to get something that would last. I purchased a Sony Bravia V series that only produces a 1080p/60 signal.

I didn't realize this until after I purchased by Blu Ray bdps 350 player this christmas. Unfortunately my picture is not as smooth as I hoped and as the displays do at Best Buy. I was quite disheartened to learn that my 1080P that I have been talking up for a couple years is already out of date.

My question to you for everyone else in my situation, is it worth having a blu ray player if you can't get 24P?

Someone told me, "the best wine you could drink is the wine you like." In light of that, this question can be answered by me and by eveyone else. Personally, I do like the 1080P resolution and I can tell a difference. I also love the upconversion. I have actually strayed from buying DVDs over the last two years in anticipation of owning a blu ray player.

I guess I am looking for more technical reassurance that this purchase was still worth it. I am on the fence about perhaps bringing the Blu Ray player back since I can't maximize it's potential. I really wanted that realistic look that Spider Man 3 displayed at the store.

Your insight and opinion would be greatly appreciated and I hope to see your response.

Sincerely,
The unfortunate 1080p/60 owner

I bought a V series Bravia three years ago when they first came out and I have really enjoyed the set and the quality of its picture. I have a BluRay player and I think the picture is incredible, the judder people refer to are for eyes far more discernible than mine:)

My question to you for everyone else in my situation, is it worth having a blu ray player if you can't get 24P?


IMO, absolutely!

Of course, in the ideal world, your TV would do 24p perfectly, but you had 2-3 years more HD than most who waited had, so there is that.

Also, what would your alternative to Blu-Ray be? Up-converted 480p DVDs? They simply can't compare to a Blu-Ray, even one converted to 1080/60p (which your Blu-Ray player can do) or 1080/60i (which is the upper limit of the sat receiver when converting 1080/24p content). Blu-Ray still offers full resolution, mega bit-rates, and hi-def audio that isn't available anywhere else. And the prices of players and movies is coming down fast. Investing another cent in DVD is foolish at this point, especially given that your Blu-Ray player will do a great job of up-scaling the DVDs you already own.

And, at some point in the future, you'll probably migrate your current TV into another room and upgrade, and when that happens, would you rather your copy of The Dark Knight be on DVD or Blu-Ray? I thought so.

Last, do you really think that TVs won't continue to improve and add cool new features every year? We're still in the MIDDLE (not the end, but the middle) of the transition from standard def, which was around for 70+ years as the standard, to Hi-Def and digital. It'll be another 5 years minimum before things truly settle out. Your gear, which is darn good, will do you just fine until then.

This is my first time visiting the web site. Thank you both who responded so quickly with your opinions. I agree with what you have said and feel more confident in my decision to go Blu.

The upconversion is really nice and I can now feel comfortable purchasing new DVD's on the 1080P format.

So when Wolverine comes out late this year or when the next Harry Potter film comes out, I will be looking forward to the Blu Ray versions!

As a side note, I have searched forums on this website for a conversation about aspect ratios. I have been pleasantly suprised to see 1.85:1 on some blu rays as I am one for taking the full screen as best you can.

IIP, do you have any thoughts on 1.85:1 and do you think more new Blu Ray DVDs will come out in this format?

Thanks again,
Vanthony

Blu-Rays will use whatever Aspect Ratio the filmmaker selected, and directors focus and prioritize on the movie theater experience, not the home experience. Generally, they will use 2.35:1 for special effects or "epic" movies where the backgrounds are a big part of the story. 1.85:1 is usually used for dramas and comedies where it's all about the people, not the scenery.

The Dark Knight is one of the only movies to date that's been a little different: several scenes for TDK were shot in IMAX, which is 1.43:1 format, to allow more detail, and were cropped down to 2:35:1 for the movie theater prints. On the Blu-Ray, these scenes were only cropped down to 1.77:1, so you'll notice that on those IMAX scenes, your whole TV screen will be filled. I don't know of any other movie that's done this, but the result is that you actually get to see more of the shot than in the theater.

I wouldn't expect directors to shift everything to 1.85:1, though. From their perspective, the fact that a movie theater does 2.35:1 better than the home TV is to their advantage: it helps put behinds in movie theater seats, which is where they really want you to watch their movies.

Picture quality looked great on these. However, not all were DD5.1

If and when I pay for a 1080P/24hz movie it best be DD5.1

I'm going home tonight to hook-up my ethernet cable, so I can start downloading DOD trailers and movies in 1080p.

I'm at work right now and can only view DTV's DOD titles on their web site. NOTHING...I SAY NOTHING...has a 1080p logo next to it on DTV's web site.

Is this normal? Do they only put the 1080p logo next to the titles when I searching for programs using my receiver?
