The Continuing War Between Blu-Ray & HD-DVD

And Comcast (and I’m pretty sure most all cable/sat) does their HD broadcast in 720p. HD/BR are 1080p.
There is a difference. Upconverting might bring you close to the 720p (so really your HD on Demand is no better than the upconverted DVD), but still, as I’d said, the bigger screen or more graphics you get, the more you’ll notice the picture quality difference. On a smaller screen the noticable difference is minute.

over the air HD (locals with an antenna) is either 720p or 1080i depending on the station.
msot use HD-lite meaning they compress the signal, to help with bandwidth & the the set-top box decompresses it.
some companies do better jobs then other…they downscale from 1920x1080i to 1440x1080i or 1280x1080i…Dish still have some that were still running @ 1920x1080i but i’m not sure if that changes.

where over-the-air 1080i is true 1920x1080i.

i think some subscription channel still only offer 720P…ESPN was one unless they changed.

so basically they give the signal to the provider in either 1920x1080i or 1280x720p & the provider rebroadcasts it…but to my knowledge 720 is not downscaled…only 1080i.
