Blu-ray Format Help Needed

[ChrisTeam]

Hello everyone, i'm all in the blu-ray corner of the still small high def world. I do have lots of confusion about formats and how the new blu-ray discs/players/hdtv work.

Is it true that in the blu-ray specs the following formats are supported?
1080/24p, 1080/25p, 1080/23,98p, 1080/30p?

I understand that the blu-ray movies are released in 1080/23,98p so far for the us market. Is this true?

Now how does the process work to get from that to the hdtv tv that i guess in the usa will still do a 29,97fps or 59,94fps picture? Is there a on-the-fly 3:2 pulldown in the player or is it in the tv? Or does the tv actually show a 47,96fps picture then? see, confusion

Also will the european movie releases on blu-ray disc be 1080/24p? And if so, will the european tvs show a 48fps picture or how will that get to a 50fps tv signal? I'm lost...

Feed me Information Seymore!

I have explained in other threads that historically frame rates for televiion was based on the power ssupply frequency to reduce components. TV's were around long before transistors were invented. Now TV's use internal electronics to determine frequencies, so they are no longer tied to power supply frequencies. Computer monitors for many years have had selectable frame rates normally from 50 - 75 and the more expensive ones even higher frequencies.

These are the standards for Blu Ray
1920x1080x59.94-i, 50-i (16:9)
1920x1080x24-p, 23.976-p (16:9)
1440x1080x59.94-i, 50-i (16:9) MPEG-4 AVC / SMPTE VC-1 only
1440x1080x24-p, 23.976-p (16:9) MPEG-4 AVC / SMPTE VC-1 only
1280x720x59.94-p, 50-p (16:9)
1280x720x24-p, 23.976-p (16:9)

SD
720x480x59.94-i (4:3/16:9)
720x576x50-i (4:3/16:9)

The HD Displays (TV's / monitors / projectors) will handle all frame rates. Most HD Displays today can't handle 1080p, more are being released almost daily that can. Blu Ray players can also down convert to 720p even if the source is 1080 p or i.
Like with computer monitors the HD display can change frequency to match the input signal. There is NO more PAL and NTSC in the HD world, but there are 2 SD standrds that closely replicate NTSC & PAL, however all HD Displays can play both. There are different broadcast standards around the world but they seem to fit one of the above formats. The only thing stopping a Disc being taken from the US for example to the UK is DRM (Digital Rights Management)

so far thanks for that, i tried to find the specs but i kept finding different ones.

I keep reading that the displays that are available on the market only process
59.94i signals and thus we still get the 3:2 pulldown with the blu-ray. Even worse european 25fps content now gets a speeddown to 23,98fps because the players dont support 1080/50i yet...

Maybe its a european thing then, but i dont manage to find a system that actually supports the 1080/24p or 1080/50i native at all And for the european market a 3:2 pulldown is just nutty, because we never needed it before and because it does result in uneven movements...

Oh well i keep looking
