Knowing that 525p is really 480p is it the same for my above question? does some information get lost due to the processing?


Thanks!

Does any one know? Does anyone care? Heeellllooooooo.

I don't think it is the same thing. 525p is 480p + the proper number of blanking lines needed to set the timing right. I believe 1125 is the proper blanking patteren for 1080i.


Someone correct me if I am wrong.


Thanks

Brian,


You are right.


What's equally important is the full resolution.

Outside of blanking, NTSC media like DVD is 720 X 480i, whereas HDTV is 1920 X 1080i.


Generally, 960i is just 480i upconverted. So the actual resolution is still 720 X 480, just better defined and smoother being scaled to 960i. With 1080i having natively 6 times the picture information (after blanking allowances).
