Hi,

Ive been looking at the HDCookBook and looks great. However a few questions have popped up :

1. Does the API and tools available actually assist you in burning the bluray disc or is it simply for bluray authoring. ?? Do you still require commercial bluray burner software to actually burn the discs ?
2. Does anyone know if its possible to burn the bluray image onto a normal DVD and would that need to be in UDF2.0 format to be playable on a bluray player or PS3 etc?

Thanks for your help,
Phil.

After many test, PS3 (retail version, not debug BD version) don't accept "BDJ" only on DVDR.
Really strange because no problem with HDMV, PS3 accepted it like a AVCHD.
I will try to test a HDMV with BDJ part.

There is no need for commercial burning software on Mac OS X (10.5), it's all build in.
Just do a

[i]newfs_udf -r 2.50 /dev/disk1[/i]

where disk1 is your BD device. You should get a message like this when newfs succeeds:

[i]write to block device: /dev/disk1 last written block address: 12219391[/i]

After that you can copy files from Finder with drag and drop to your disk.
Maybe you have to "initialize" your BD from Disk Utility first by erasing it
(so newfs can determine the disk size).

Hi Oliiver,

Does this support incremental updates? That is, if I've previously made
a UDF 2.5 disc image (including big transport streams), and I just want to
swap in new JAR files, can I just mount the FS, replace the JARs and unmount
it, using the standard OS/X drivers?

Yes, please have a look at newfs_udf's man page for more options:

[i]-t access-type
The access type of the partition, can be wo (writeonce), ow (overwrite), or pow (pseudo overwrite), default: ow[/i]

Hi Phil,

Not sure if this got answered before, so here goes. To burn the disc, you do need
commercial bluray burner software, of the sort that burns a data disc at least.
Usually that's included with a BD drive for a computer.

It should be possible to put the image on a normal DVD, I think, but I've never tested it.
The name for a Blu-ray image on a physical DVD disc that's read with a red laser is
"BD9", the "9" being for the 9 GB of a double-sided DVD.

I'd be interested in hearing anyone's experiences who experiments with this.

Cheers,

Bill

The BD9 spec only supports ROM media, not burned. Also it is supposed
to require AACS (as does BD-ROM). That's not to say that some player
implementations might not be more liberal in their interpretation of the
spec, however, so it might be interesting to experiment a bit...

Not agree about BD9 with non-AACS, EclipseData updated in october their mastering system for:
"Implemented preliminary support for the BD9 non-AACS BDCMF format."

I want to know nobody test it ? BillF ?
I will be the first !?
Nobody know if PS3 support BD9 if it's on ROM media.
I know some people change index.bdmv to play BD on DVDR in PS3 (only HDMV no way to BDJ...).

Last I want to know the difference between BD9 and AVCHD, why:
because HDMV project with little patch (index.bdmv) is accepted by PS3 on DVDR like AVCHD !!!!

Nope, nobody I've known has tried it. It'll be great to
know if it does work!

BD9 on ROM media with AACS and everything is, I believe,
required to work. I think it's a formal requirement, but
even if it's not, I'd expect every BD player to also have a
red laser in it to read DVDs and CDs and such, and the increased
data rate needed for BD-9 is only on the order of 4x, which is
easy.

> I know some people change index.bdmv to play BD on DVDR in PS3 (only HDMV no way to BDJ...).

Good data point that suggests BD-J will work too.
I'd be interested in knowing what happens on some of
the other players, too.

Cheers,

Bill

About BD on DVDR, all Sony BD player accept it (except PS3!!).
I know that Panasonic and Pioneer support it (feedback no tested by me).

Many people use it to backup the "old" HDDVD format on BD9 project.
But BD9 is not only a BD on DVD disc (lot of restrictions,...).

BillF, there is no restriction of BDJ on BD9 (graphic buffer,...),
I don't have the "BD specification ROM2 Part 1" to know all about BD9.
I hope to see you, Bill, at NAB

No, nothing like that. As far as I know, the only specification elements
related to BD-9 talk about physical layout of a DVD-ROM disc, which can
be either a 4.7 GB or a 8.5 GB disc, by the way.

Cheers,

Bill
