Writing To Persistent Storage

I've been working on this for what seems like an eternity now, but I can't get it to work. I want to be able to write an XML file to the persistent storage of an HD-DVD player. So far, this is what I have tried.

- Going from the disc, to the filecache, then to the required storage. Failed when going from the filecache to the required storage.

- Going straight from the disc to the required storage. Fails instantly.

- Creating a file on-the-fly, and then going to the required storage. Fails again.

I am placing the file inside of a folder in the required storage. The folder name is the content ID from the DISCID.DAT. The only thing that comes to mind is that the disc has to have AACS applied for it to work. I hope I am wrong on that account. Some insight is needed and very much appreciated.

Let's see if I can make the bad news even worse. Do you know if AACS just has to be initially set from the authoring tool or does it have to go through the whole premastering and AACS certificate process

You are correct -- you need to be AACS-enabled in order to access persistent storage or to use the network features of a player. This is to prevent malicious content from harming your device. You can simulate this behaviour with iHDSim with the -restricted command-line option.

There may be other ways to do this in the future, but right now it's AACS or nothing I'm afraid.

It's OK Peter. I can't say that I'm not surprised now that I think it out. Fortunately, the Sonic software emulator will run it without the need of any encryption. Do you happen to know if the Toshiba emulator works the same as the real player

Hi, everyone

Can anyone give more detail infomration about Restricted Module, I know I can't use the network features and can't write to persistent storage. it is said I also can't do the DOM manipulation, which I don't know much. Could any tell more detail information about what I can do and what I can't do for the DOM in restricted Mudule. many thanks!

There shouldn't be any issues with restricted mode and DOM manipulation. What in particular are you having a problem with

You should ask Toshiba about that. Player manufacturers need to make sure content authors can test content on their players before it goes to final replication with AACS, etc. but there is no defined way to do that.

You need the whole shebang, with title keys protected by the media key block and content certs signed by AACSLA and so on.

Sorry to be the bearer of bad news...

The Toshiba Emulator does allow you to write to Peristant Storage and allows network access. To my knowledge, there are not restrictions on the emulator. And yes, the emulator runs exactly as the standalone player does. The only difference between a retail and the emulator (besides the price) is the emulator has a harddrive inside (instead of a HD-DVD Drive) and has no restrictions.
