Re: HD vs Blu-Ray.....


It was interesting (not surprising- I'm sure Sony et al pay for those displays out front), but I take issue with this:

Quote:
The transmission interface is simply a matter of the order in which the scanlines are read and transmitted to the video display. If they are transmitted in 1080p, they are sent sequentially. If they are transmitted in 1080i, they are sent in two fields, with one containing the odd numbered lines and another the even numbered lines. These two fields are then reassembled into sequential frames by the video processor in the TV or projector. Either way you end up with the full 1080p frame being used to create the picture, so there is no difference in the end result.
That's saying that interlaced and progressive are the same thing. They aren't. Interlacing depends on the human eye not noticing a delay between the alternate images- and usually you don't (regular TV is interlaced).
