RE: 480P - Anyone know what this is?

	480p = 480 Progressive.

	This is one of the many ATSC digital TV standards. 720x480 pixels,
progressive scan (as opposed to interlace). Usually (but not required) in
16:9 aspect ratio. Frame rate is variable (24, 30, and 60 frames are all
permissible)- for instance, Fox Broadcasting here is preparing to broadcast
film originated programming in 480p/24 FPS this coming season (on a separate
digital feed). The advantage is that it can be sourced from current standard
525/60 601 masters (pulling out 3:2 pulldown). The disadvantage (to those
who consider it such) is that it's not true "high definition." 

	It has nothing to do with standards conversions.
