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.
