what's up with 1080i setting but no 1080p?

what's up with 1080i setting but no 1080p?

So I ordered HD upgrade. On the DVR settings I figured I'd see what settings there are, so I go the screen settings and the highest one is 1080i...

What's up with that? Am I really getting interlaced frames? Can this DVR not output 1080p?

What am I missing here?

I have to believe you guys are getting 1080p...

No channels broadcast in 1080p on any TV provider.  The extent of 1080p programming on any TV provider is DirecTV and Dish Network providing some PPV movies in 1080p.

Oh, I did not know that. I guess it's a bandwidth thing.

Thanks for the info.

Well, there are no channels that broadcast in 1080p.

If you have a newer set capable of 1080p native thats what you will be looking at with 1080i.

It will take the 1080i signal and scale it to the native resolution which on most newer panels can be 720p (LCD) ,768p (Plasma) or 1080p (both LCD and Plasma) depending on brand and model.

I don't see how it can take interlaced and turn it into progressive though (I own a 1080p LCD and the DVR says it is outputting 1080i as the highest resolution), AFAIK you cannot take interlaced and "convert" it into progressive without losing a frame every time you do.

Think 1080i @ 60 frames per second versus 1080p @ 30 fps there is no loss of info just one nice continuos motion.

Right, but what we are getting is  1080i  @ 30FPS right?  So if it converts it 1080p we'd be getting 15FPS which would not be a nice continuous flow...

 

It seems to me the reason Uverse doesn't stream 1080p @ 30FPS is it would take up too much bandwidth, so why would they stream 1080i @ 60FPS?  Wouldn't that be the same bandwidth?

No one streams 1080p.  Except for Blu-Ray and some On Demand from Dish (or is it Direct?) there is no 1080p. 

 

This is a broadcaster issue and not a carrier issue.

Re: what's up with 1080i setting but no 1080p?

Yeah that was established near the first post.

What came up now was that Oz was saying my 1080p TV could somehow take a 1080i signal and turn it into a 1080p signal, and I was saying that isn't possible unless I lose half of my frames.  And unless Uverse is giving me 60FPS of 1080i (not sure why they'd be doing that) then what he's saying isn't possible, unless I missed something.

That's the statement I was responding to but then again, I'm an i diot when it comes to all this technical mumbo-jumbo.

Yeah since I'm super late to the HD game, I figured we were up to the point where service providers could to 1080p now, but it looks like it is still too much bandwidth.  So yeah you're right, only Blu-Ray and game consoles and stuff can do it.  1080i is still TONS better than that SD crap I was watching before though, plus my phone actually outputs 1080p on everything i record like with the video camera or movies/streaming, so that's pretty cool to watch on a big 1080p TV.

No its 1080i at 60 frames which is odd even hence interlaced and 1080p is actually 24fps as is what film is or video which can be 30fps there is no such thing as 1080i 30fps as far as I know which would result in a bad picture IMO. 1080i = 30frames of even and 30 frames of odd where as 1080p has 30 frames of the combined in a single frame.
