I was wondering if in the future in the video format section for blu-rays if there could be an option to indicate if a disc is 1080p or 1080i. By default it could be set to 1080p, then for discs that are 1080i, that could be an option.

Plus for any discs that are 1080i, it should also be an option to indicate what the refresh rate is; 60 (NTSC format) vs 50 (PAL format). I have a few European Blu-rays that are 1080i, and 2 of them are in the PAL format, all the rest are NTSC. Such information may be useful to know.

Thank you for your time.

Agreed, I would find this very useful...and the back cover's don't always reveal these things.

It has been proposed in this thread also.

Very useful information, indeed. +1

In fact, I'd love to have two fields for video on Blu-ray:
- Resolution: 1080p, 1080i, 720p or 720i
- Codec: AVC, MPEG4, etc

One problem is that sometimes it's just a menu or bonus feature that is 50 Hz while the main feature is 60 Hz or 24p. Yet some players refuses to play them because of that. How should those be handled?

It should be handled by giving the industry a kick in the butt, returning the product and demanding a refund or useful replacement.

Dolly's not alone. You can also clone profiles.

I would propose we only profile the main feature and not the video material of the extras.

There is no 720i. Refresh rate on 1080i is important as most US equipment can play 60 Hz, but not 50.

So you don't mind if the disc is unplayable because it has a menu with the wrong refresh rate?

If you can't play it, you can't profile it.

Well, people might want to use this data to figure out if they could play a title.

That's incorrect, I can use a disc tool to examine the disc, I don't have to actually play it.

FYI, NTSC and PAL do not exist for HD.  Technically they don't exist for SD either.  NTSC and PAL are ANALOG video specifications and have nothing to do with digital.

Digital video, both SD and HD, need to be described only by the resolution and frame rate, i.e., 1080i29.97, 1080p23.976, 1080i25, 480i29.97 or 576i25.

Technically DVDs are not NTSC or PAL, as there is no color subcarrier on a DVD.  It is the player that takes the video and converts it to NTSC or PAL.  And that only applies to standalone players that have the output sent to an analog TV.
