Hello everybody,

I would like to know more about BD-Live application development, is
it some kind of framework or a set op API's?

Where can I find any usefull information to start development?

I have signed up for the developers disc at BDLive.com, but haven't received
anything yet. I send some e-mails to RCDB.net about the staus of this disc but didn't get a response.

Thanks,
Marco

Hello Marco-

I apologize for the delay with the developer disc. We are working with the support of Sun and should have an update for you shortly.

Thank you for your patience and please feel free to contact me with further questions.

How you tell us a little about the disc and what we can expect to have on it?

We have heard there are replication issues with the BD Live flag and we have heard about titles that have had a lot of issues when it comes to AACS and BD Live. Do you have any tips and advice on how best to prepare a title for BD Live?

Yes, it does get complicated if you want to encrypt the downloaded
content. There are some example use cases in the AACS BD Pre-recorded
spec, but that doesn't cover all possibilities. Hopefully the
workflows will be worked out over the next few months - new tools,
etc. are required for encrypting streams (vs CMFs) and there are some
policy questions around who can possess keys used for encryption. More
questions than answers right now...

Easiest thing is probably to use a specific title for updated content
with its own CPS Unit set for unencrypted use. With this method one
may be able to avoid having to download additional AACS files with
each update, but of course the downloaded contents aren't encrypted.
It gets more complicated if you want to download PiP or additional
subtitle/audio streams, as those need to be encrypted with the same
key used for the on-disc content it plays with. (There are plenty of
gotchas in the AACS spec. ;)

Cheers,
Joe

Ok great so as long as one avoids trying to download mt2s, clips, and playlists, everything else should be a walk in the park, yes?

As far as the files that require AACS we'll look at the samples in the spec. However, initial question is if the replicator actually encrypts the files how can I encrypt them? All I can do is add the CPI information to the streams?

Yep, there are workflow questions. ;) One possibility is that the
replicator continues to do it. Another option may be that some
authoring houses become AACS licensees so they can legally possess
keys and tools are developed so that they can do the encryption. There
may be other models, too. It'll shake out, but at the moment there's
not one clear path.

Cheers,
Joe
