New Samsung super blu HD and blu ray in a box

PC Magazine reviewers noted an odd quirk with the SuperBlu; the player supports only the 24-Hz and 30-Hz frequencies of the 1080p format, not the most common 60-Hz signaling.This means that the player is incompatible with TVs from Sony, Sharp, Samsung, Panasonic -- and even LG, whose upcoming 2007 TV lineup will support the 24- and 30-Hz frequencies, but whose current lineup does not.

The one thing that pops out at me from that article is this 1080p60 nonsense. I was under the impression that discs were encoded at 24p (like the film they are sourced from).

Surely if you want the 50/60hz etc, 1080i can just be used? Then the deinterlacer in the tv can recover the 24p? Surely having movies output at 1080p60 from a 24p disc requires some extra processing/frame doubling etc?

Since most 1080p capable displays in the US can only accept and display p60, and most owners tend to be adamant about what they feed their expensive HDTVs (sets capable of accepting 1080p being fairly recent arrivals), there is actually some resistance to feeding 1080i instead. For those few who have p24 capable sets (usually front projectors, I understand), they are adamant about receiving a signal in that specific format.

Yes, an HDTV can theoretically perform inverse-telecine to recover an accurate 1080p60 from the 1080i60 (given the 108p24 source), though it appears the actual algorithm used (bob & weave Vs double, whatever) depends on the individual set.

The current HD DVD p60 output players first convert the disc p24 to i60 and then perform inverse-telecine to create p60.
