SD 1080i

[LoTech]

I've noticed lately that I'm picking up some channels/feeds in SD/1080i on my Coolsat 8000. Why would someone broadcast an SD channel in 1080i format? Is there some benefit over 480p?

usually those are in MPEG4....what channels in particular? I know some sports feeds have been in MPEG4 SD

Yep. TVW and UWTV on Galazy 18 are two of em. I was just wondering why they go to the trouble of broadcasting in 1080i when they are only using SD picture quality?

If it's 1080i or 720p, then it is HD. I assume you are talking about SD video that is upconverted to HD for broadcast. Do you have any examples?

Not really. I just noticed that when watching channels like OETA, PBS East/West, etc... my Coolsat 8000 shows HD 1080i as the format. When I change to UWTV it shows SD 1080i

I'm showing 720 x 480i for those two. They are not HD. Looks like the Coolsat 8000 is confused?

the coolsat8000 (and vantage 1100) read pretty much all mpeg4 channels as HD... even though they are SD...
