I downloaded the Hulk trailer and though the the picture quality was very comparable to my Blu-Ray. There are several movies listed that we may want to pay the $4.99 cost instead of buying the actual movie.

But how can you tell if the movie will be in 1080p or not? I clicked on several of them, but cannot find anything that shows 1080p.

There will be a 1080p icon next to 1080p content when it becomes fully available.

The A3000 series should work fine. Older sets only supported 1080/60p, which is the format used for video-based sources, such as video games, computers, and live TV.

Film-based sources are encoded for HD at 1080/24p, because film is a 24-frame-per-second format. Film-based Blu-Rays and the "1080p" VideoOnDemand from DirecTV, Dish, and eventually others, will be encoded at 1080/24p.

The problem is that older HDTVs don't support 1080/24p input signals AT ALL (requiring conversion by the source device to 1080/60i), while others can accept these signals but have display panels that only work at 60 Hz, which means that they have to internally convert the signal to 1080/60, which introduces timing problems, since 60 can't be divided by 24 evenly. This has ALWAYS been an issue when watching film-based content on TV, but the larger displays and higher resolution that is becoming common today, as well as the properties of non-CRT displays, can make it more noticable.

In 2007, the first consumer TVs were introduced that could display 24 fps content properly, by using displays that can be refreshed at a multiple of 24. Thus, by repeating each frame the same number of times that the refresh rate is a multiple of 24, each film frame is displayed for a total of exactly 1/24th of a second, restoring the proper cadence of the film and giving you back the "film look and feel" that you get at the movie theater.

This ability was brand new last year, and only available on a very few high-end TVs. In 2008, it became more widely available, being offered by most brand-name TV manufacturers on their upper-end models. Over the next few years, you can expect this to filter down to cheaper models until 3-4 years from now, it becomes a standard feature on all but the cheapest TVs. The same thing happened with "1080p" support, which was really 1080/60p support; it got introduced in a few high-end models, and "trickled down" to lower-end models over a 5 year period, until almost every TV made today support it.

For folks with older TVs, you can still watch this content, but first it will have to be converted into a format your TV supports, either by the source device (Blu-Ray player, sat receiver, etc.), or, if your TV accepts 1080/24p signals, by the TV itself. You don't get the full benefit of the format, but there IS still some benefit from the satellite VOD: these "1080p" VOD movies are encoded in a higher bitrate than is practical for standard broadcasts. That means less compression is used, so there are fewer compression artifiacts in high-motion scenes, and less washout of colors. In many cases, the sound is also less compressed, so you'll notice an improvement if you're using a good sound system.

Perhaps your tv doesn't support 1080p/24, but only 1080p/60. From what I have been reading, the 1080p output of the Hrxxx dvrs are 1080p/24. Don't ak me why Dtv decided to go with the less common format, since it seems most tv support 1080p/60. Maybe someone else can explain better then I have.

BTW, if you're having problems with your TV, it would be much more helpful if you could post both the brand AND the model number of your TV.

hey mine is an A2000 so that is right .... does that mean that if I get a blue ray player I wont get 1080p...I'll just get 1080i? albeit a very good 1080i

If you get a Blu-Ray player, then film-based content, which is encoded at 1080/24p, will have to be converted by the Blu-Ray player into 1080/60i or 1080/60p, whichever is the best that your TV supports. Video-based content that is already at 1080/60p or 720/60p will not have to be converted.

It is that conversion that the new technology *finally* allows to be avoided. The conversion of 24 fps to 60 fps has always been necessary, because until recently, all (NTSC) TVs were 60 Hz only, but always been undesirable because the frames couldn't be repeated (to fill 60 screen refreshes per second) at an even rate.

Ideally, each film frame would remain on screen for 1/24th of a second, like it is in the movie theater, but that isn't possible on a device that refeshes at 60 fps; 60 isn't divisible by 24 evenly. So, the compromise has always been to use a 3:2 refresh cadence. This means that the first frame is repeated 3 times, and the second frame repeated twice, and so on.

Because the odd-numbered frames are on the screen for a longer period of time than the even-numbered frames, this creates a visible problem called "judder." And while TV viewers have lived with this for 70+ years, higher resolutions, larger screen sizes, and new display technologies all conspire to make judder more apparent, which has led, finally, to newer TVs having the ability to refresh at rates that are even multiples of 24, eliminating judder.

I finally added an A630 Sammy 52" to my stableand would like to see any content available on DTV (like the Hulk trailer). How do I get it? I can't find a recent thread about it.

Thanks,

Go to Channel 1100 and search (or scroll down) for "Test your 1080p with the HULK!"

First, you have to have an HD-DVR hooked to the Internet via Ethernet (or a wireless or powerline conversion).

Do a SEARCH (to search the Guide) and type in "TEST". This should locate the Hulk 1080/24p trailer. Download it. Before you watch it the first time, the receiver will test to see if your TV reports the ability to accept 1080/24p input signals. If the TV reports that it does, you'll be able to watch it in 1080/24p. If the TV doesn't report 1080/24p input capability, then the receiver will convert the signal to 1080/60i.

A few TV models DO accept 1080/24p input signals, but do not correctly report this capability when the HDCP handshake occurs. This can be "gotten around" by pressing the INFO button during the test, which you're only "supposed" to do if the test is successful. Of course, if you press INFO for a TV that doesn't support 1080/24p, then you'll have problems with the picture when you try to play 1080/24p downloads.

FYI.. Doing a keyword search for 1080P and selecting all categories will supply you with a list of all things 1080P (and 1 or 2 extras....)
