Lets not forget one key fact; the satellite decoder chipset on the HD receivers does not support 1080p.

So no, 1080p is not coming anytime in the near (or far) future.

Thanks :) I still don't understand all this resolution business. I just want to know that the HD TV I just got last year and is still not completely paid for is not going to be a piece of junk any time soon! I'm still stuck with one SD TV as it is :mad: Because it isn't old enough to even think about replacing it yet :(

The future of 1080p broadcast is here - XstreamHD !
And reading old threads will give more facts - http://dbstalk.com/s...ad.php?t=115434


Not really a broadcast. They way it is supposed to work is, that films will be downloaded to the DVR.

Did you provide citation for your source ?

Little fact if you're not aware - Blu_ray DVD player use SAME decoder.

Broadcom's BCM7401 is capable of 1080p in 24 and 30 frames per second. So the HR21 DVRs are capable of producing it. Though it comes back to source and if they are programmed to produce it. I think the HDMI port may be 1.1 though, but I don't know if that limits it.

The other major fact, is that the majority of consumers sit too far away from their sets (distance vs. screen size ratio) to distinguish between 720p and 1080p anyway.

Everyone wants 1080p because they believe it's the best, but then they sit 10' away from their 50" set and don't realize that they're eyes wouldn't be able to tell the difference anyway.

I'm sure Directv can't wait to get their hands on your unit.

a) you stated not a fact

B) "satellite providers are already preparing to offer full HD channels in the next few years"

a"satellite providers are already preparing to offer full HD channels in the next few years"


The above referenced article is full of misinformation.

First it implies that cable and satellite broadcasts of movies aren't "Blu-ray quality” because they are in 1080i instead of 1080p, which is complete nonsense. 1080i can produce 30 full progressive non-interlaced frames per second at the same resolution as 1080p….. more than enough progressive frames to encode the 24 frames per second frame rate of movies that are typically on Blu-ray discs. The quality difference between Blu-ray and cable/satellite comes from the higher bitrate that Blu-ray uses, not from being in 1080p. Reproducing a 24fps movie in 1080p offers nothing whatsoever that 1080i cannot deliver given the same bitrate.

Secondly, the idiot from Tanberg TV who is the source of the 1080p predictions seems to think that satellite operators have an abundance of spare unused bandwidth that they will use to provide the “Blu-ray quality” broadcasts that he is predicting.

In short, the guy’s company has a vested financial interest in providing advanced digital TV technology, so of course he’s going to try to push the proposition that the current video delivery technology and methods will soon need to be vastly improved.... of course, with the help of a company like his.

Sure, there is a push, but all gadgets including HDTV and FullHD TV sets cames after such pitches.

Bumped since there was a request to continue this type of discussion from the HD Anticipation thread.

I would like to suggest we take the 720p vs 1080i discussion to its own topic. It's not really related to DirecTV, nor HD channel anticipation, and completely depends on how the channel in question broadcasts.

If someone would PLEASE be so kind and create a topic in another forum - perhaps "General Satellite Discussion" - it would be much appreciated.

Thanks :)

What's the point?

720p vs. 1080i is a subjective preference and tastes will vary.

It's like Vanilla vs. Chocolatae or Ford vs. Chevy

Virtually the same amount of information per second is passing through with either format.

At least some of the immediacy of the topic has been dulled with the passage of four years: Not many 1080i TVs around; it's all 1080p, vs. 720p sets. Then the main question becomes: At what size set would it make no perceptible difference to go with 720? I'm guessing 30" or less.

It's just amazing to me that otherwise intelligent people can simultaneously hold the belief that the "p" in 1080p makes it better than 1080i, but the "p" in 720p does. . . nothing.

Umm, what?

Having said that, are modern 1080p TV's essentially upconverting 1080i to 1080p thru buffering and post-processing? Does it actually make it a little better? Not like native 1080p, but better than it would be otherwise?
LR(non-CE): HR44, Mits 65C9; Office/FR (CE): HR22-100 + AM21, Mits 60737 + Mits 3DA1 3D adapter. Spare bedroom (non-CE), HR23. Genie WHDVR, wireless networking (yay!)

It's well known fact - if you want learn - read what chips ( using in HDTV ) doing for video processing...
Yes, and it's big market where new chips are better and better.

I did think that was true. There's still only so much they can do as long as the native captured signal at the source is alternating 540 lines on a 100mph fastball, a slapshot in hockey, a golfball in flight, etc.

You're not really arguing that with modern tech (say a top-end TV built in the last year) that upconverted 1080i is as good as native 1080p?
