Default Comcast cable box for 1080P?

I see the SA8300HD processes signals up to 1080i. What box for a 1080P set?

Neither Cable, Satellite nor Over The Air Broadcasting operates HDTV at 1080P.

Only HD DVD and Blu-Ray Disc can output 1080P

Not even FIOS operates in 1080p, right? When is this expected to change?

What good would it be "if" fios did send 1080p - where would they get the content? If they did send 1080p it would be deinterlaced 1080i and uprez'ed 720p - A 1080p display does this by itself. I doubt if we will see a change anytime soon.

In about 20 to 30 years.

The last change; 480i to 1080i took over 50 years (1945 to 1999)

Yeah, but 480i was here for 50 years (at least in the US) before there was any upgrade at all. Ultra HDTV will probably be out by 2025, so I'd be very surprised if no providers put out 1080p by 2010.

So where does HD DVD and Blu Ray get the content? If FIOS or anyone else did send 1080p, the content shouldn't be hard to find (plenty of 1080p movie sources out there), it's sending it and updating their equptment that should be a problem.

You are being VERY progressive in your thinking about the TV providers. In any "upgrade" that has ever happened with the exception of Color TV - they are the very last to implement it. Stereo, higher resolution just to name 2.

There investment in 1080i has no way for it to pay for itself. They can't and don't charge their ad providers more because because they are now broadcasting in HD. This has been the problem since day one of OTA HDTV.

It cost millions of dollars to change from 480i to 1080i. The reason why they make this expenditure is to stop the fear that the viewer is not watching their channel because it is not in HD.

They use two of everything - just in case one breaks during broadcast - they flip a switch and the backup immediately takes over.

The problem is bandwidth. Or did you not know that both DirecTV and DISH lower the hort. resolution of their HD feed from 1920 to 1440 to that they can offer more HD, though at a lower res.

We would have to go to either 1080Px30 or 1080Px60 with the second one being literally impossible due to the bandwidth requirements.

Super HDTV or Ultra HDTV is coming. In about 7 to 10 years. But it will be a media based product like HD DVD or BluRay because now we are adding 2.5 to 4X the picture info.

Bingo! You have uncovered the dirty little secret. 1080p/60 transmission between the player and the TV is mostly a marketing trap. Now there are a few sets that will take a 1080p/24 input signal and player that will output 1080p/24 will be of benifit to eliminate the 3:2 judder, but there is no resolution difference between a 1080i/30 signal and a 1080p/60 signal.

Now if you hook up a game console (PS3 or Xbox) or a computer, the 1080p/60 input can be very worthwhile.
