1080i or 720p?

[GMichael]

On that particular channel, the 1080i source SHOULD look better simply because the antenna gives you the original signal at the original resolution. Your cable box signal is a retransmission that might have gotten compressed or otherwise modified in the process.

Are all sources using the HD cable box getting sent out in 720p? If so, you'll need to check you box setup and make sure that it is setup to output 1080i signals in their native format. If it's not a setup issue, then your cable company is downconverting the signal to 720p to conserve on bandwidth -- not a good idea. All satellite and cable services will compress the video signals on their systems, but most of the time they will maintain the signal in the original resolution.

Ahhh...
I didn't think of that.

Is a moot point really, because most sets sold these days are either 1080p or 720p.
1080I AS A DISPLAY is just about out the door, even tho its still an exelent
broadcast medium, since its so easy to deinterlace to 1080p.
Get a 1080p, stay ahead of the curve.

So far I see that all the HD channels coming from the HD box are in 720p. My HD box is a Motorola DCH3200. I downloaded the manual for this box from Motorola's website and discovered something interesting. The manual has a section called "OPTIMIZING YOUR DCH RECEIVER FOR HIGH-DEFINITION TV". This allows you to get into the box's settings example:
User Setting Status - TV Type: 16:9, YPbPr OUTPUT 1080i, 4:3 Override 480i
This setting seems to be geared to the Component Video but I'm using HDMI. Later I well hook up some Component Video and see if I get the 1080i as indicated. I'll keep this thread posted as to the outcome when I do.

I don't see 720p on my set anywhere. How do you get 720p? I get 480i on my SD signals and 1080i when I go to the HD channels. I have verizon, maybe they don't broadcast in 720p anymore.

On Motorola boxes you turn the power off, then hit the menu button.
The configuration screen comes up and you have choice of several different options.
720P if you have a 720p set, if the deinterlacer in your TV is better choose the 480i
on the 480 override option, if not choose 480p.
CHOOSE SOMETHING THAT TAKES THE PIC OFF, AND YOU CAN USE THE FRONT DISPLAY TO GET IT BACK.
Good luck.
