I just wanted to share this graphic I received a while ago, which explains the CPL naming conventions studios are starting to use. This was developed by the NATO technologies committee and SMPTE. I had to size this down about 15% for FT to accept the upload, so I apologize if the text isn't clear. I can share the full res graphic with the admins if desired.

The full graphic with lots of other details is at http://digitalcinemanamingconvention.com .

I think http://www.isdcf.com did a lot of work on this.

Also, there's a SMPTE group working on a specification for CPL metadata. This would allow data about the DCP to be reliably parsed out (before ingest, I think) making it much easier to figure out which DCP to ingest or play. I think a server should be able to, if desired, sort DCPs to show them ordered by compatibikity with the auditorium or sort on any field.

I think that the capabilities of the auditorium (picture and sound) should be able to be configured into each server. And then the correct version is what is ingested for that auditorium (with manual overrides, of course). Yes, all capable versions should be there but the default should be the one with the best sound format and such.

If the house doesn't have 3D...don't even offer the 3D titles or trailers.

But what if the house is 3D capable, and there is a 3D version of the title that is playing, but that house is playing the 2D version? (Say, for example, there is an abundance of 3D screens in the complex and not all of them are needed for 3D content that particular week.) Would the system still automatically ingest and schedule the 3D version, require manual override to schedule the 2D version?

Ken, what he means is that if you schedule a 3D show in an auditorium, it will automatically transfer the correct 3D version - 5.1 or 7.1, 3.5fl or 6fl, silver or white. Same thing if you schedule a 2D show.

Of course you will still be able to ingest ANY content available. Metadata will just offer a default or preferred choice.

Plus metadata could also be used for things like preventing red band trailers on features that aren't rated R or NC-17. As of right now the studios are including very little, if any, metadata in the average dcp.

If I had my way, a house with 3D capability would have the option to set, AS ITS DEFAULT, the preference to ingest BOTH the best match for 2D and 3D.

To add to the confusion there have (in the UK) been features released simultaneously at more than one BBFC age classification (with other edits to avoid sensitivities)

18 Rated, 82m 32s (not released)
18 Rated, 81m 16s long (Michael Jackson reference removed) and
15 Rated, 79m 06s

For anime films some cinemas show dubbed versions during the day and subtitled versions at night, how would the automatic system deal with these.

-------
BBFC classifications are provided as guidance to local authorities who may choose to impose their own ratings.

We are NOT talking about automatic systems. Metadata is there to make human decisions easier.

What's wrong with defaults?

Is LtRt now a valid soundtrack configuration for DCPs? This page suggests that it is.

If Lt/Rt means matrix encoded, it would be hard to believe they include Lt/Rt but not plain stereo. Thus I doubt they actually mean matrix encoded 2ch.

I emailed ISDCF and they confirmed, it's a mistake, it should read 'Left/Right'/'Stereo', not 'RtLt', they will change the table.

Nothing, of course, but 'defaults' are not 'automatic', they leave a choice, only suggest a potential candidate initially. ;-)
