1080p on PV500

What happens if I feed the Pv500 a signal that is 1080p? Does it show anything? Anyone know? Just wondering how this HD is going to work when Blu-ray or HD-DVD discs come out

HD-DVD and BluRay discs may well be mastered in 1080/24p or 1080/25p, but it is likely that the players will output these in 1080/60i and 1080/50i suitable for existing HD-Ready displays, as well as 720/50p and 720/60p as well. It may be that first generation HD-DVD and BluRay players don't actually output in 24p or 25p at all... There aren't many domestic displays that would accept 24p or 25p inputs AIUI.

For info 1080/24p, 1080/25p and 1080/50p and 1080/60p are NOT AFAIK input formats mandated by the HD-Ready spec.

so probably means that for now the standard is going to be 720p then, what does everyone think?

I would conclude that the player should run 1080/24p as full-frame 3:2 pulldown at 60 Hz (mamma mia) and 50Hz 2:2 with speed up on displays that can run at 50 and 60 Hz only...I really am wandering what refresh rates are supported by plasma displays...maybe 24p can be run at 72 Hz on every plasma like on PC LCD monitors (up to 75 Hz)...puzzled here, really...

For broadcast it is likely to split - as it has in the US where both 1080i and 720p are in use. ABC and Fox are 720p, NBC and CBS are 1080i.

For pre-recorded release I would expect material to be released in the format it is shot in - so stuff like Lost (ABC), Desperate Housewives (ABC), Arrested Development (Fox) if it is released would presumably be 720p, unless the shows are shot 1080p and downconverted to 720p (not the case for AD or Lost AIUI - not sure about DH), whilst stuff like CSI (CBS), The West Wing (NBC) would be released 1080. Whether the 1080 stuff is mastered 24p or 60i, and/or played out 24p or 60i will become clearer as time goes on.

For feature films I'd expect 24p on-disc, 60i or 60p (possibly with 24p optionally) for playout in US regions, with European releases being 25p rather than 24p sped up (because pitch compensation of 5.1 audio in a domestic player may not be feasible) to 50i or 50p.

Some plasmas are available that will take a 60i 3:2 pulled down 24p sourced signal, reverse the 3:2 pull down to generate a 24p signal, that they then triple-refresh at 72Hz.

1080p24 is part of ATSC standard, any large HD-LCD sold in US now needs a ASTC tuner on-board. It is likely future Japanese LCD's will have global platforms (SCART/S-Video differences), so 1080p24 may be available on future European panels even though it is not in HD Ready agreement.
