[SBE] 480p

[Scott Grizzle]

I have a lot of customers doing 480p.  But these are being used more for DVD and web based video.
 
There have been a couple of broadcasters here in San Diego that did expierment with 480p broadcast as a stop gap.  I think only one is still doing it because they just dont have the finances to go full HD.
 
In comparison to 480i its night and day.  but the same can be made for 1080i and 1080p
