JavaScript on protected and non-protected disk

  "I did read that binary files must be AACS protected if the disc is AACS protected in order to receive them from a network location. This is a major hurdle Studios, and for the rest of the world, it makes "dynamic" disc really difficult. "
  
   - No, it is just a case where the original author has to maintain the remote file system since he is the one who knows what he script is calling for. So you just have to keep your remote content named and dated correctly in the case of "latest trailers". The studios will probably have to host thier own content to ensure that this naming scheme is maintained for ...ever... This is why I like the idea of an RSS feed on the main menu to keep the user informed of any updated remote content.
  
  "Imagine a medical HD-DVD disc that can show HD images that come from the network that are x-ray images that are updated regullary to help other Doctors learn and in order to update the pictures that are usually saved in standard format they now also need to be protected by AACS then stored on a custom server that can authenticate the request correctly.  That is a process with a lot of human steps that can go wrong and cost money. "
  
   - Really great idea ...never crossed my mind.

  I thought there was a back door approach when I was reading the spec, I guess I read it wrong. I'll go through All of Annex X's API network section but i thought i read it in Chapter 9 or in the begging somewhere like chapter 2 or something like that. I'll look it up again.. but maybe it was just for text that could be sent with out the disc being AACS protected

  Does this limitation include setting my secondary video source to be an HTTP location (network) as well

  I did read that binary files must be AACS protected if the disc is AACS protected in order to receive them from a network location. This is a major hurdle Studios, and for the rest of the world, it makes "dynamic" disc really difficult.

  Imagine a medical HD-DVD disc that can show HD images that come from the network that are x-ray images that are updated regullary to help other Doctors learn and in order to update the pictures that are usually saved in standard format they now also need to be protected by AACS then stored on a custom server that can authenticate the request correctly. That is a process with a lot of human steps that can go wrong and cost money.

  Here is a question can the user place an image on a protable format such as a scan disc, and does this need to be AACS protected I will have to look this up but maybe someone knows off hand

  BD-J has a huge advantage here because updating Images is as simple as opening a new Socket (in java terms) and connecting to the correct url (http or https). I'm not in favor of either yet just that is an advantage for those outside of Hollywood if they don't have to worry about AACS.

  Is it also possible to stream from a local network, for instance using \\<computer name>\<volume>\<path>
  
  Must the data that you want to stream also be encrypted with AACS
  
  

• CoreyMc

  Correct. You can't use any URIs that are http: or https: on a non-AACS disc

  So does this mean that this statement
  <PrimaryAudioVideoClip titleTimeBegin="00:00:00:00" titleTimeEnd="01:09:09:35" src="file:///dvddisc/HVDVD_TS/FEATURE_1.MAP" dataSource="Disc"> can not be modified to get its data from a network drive

  The spec is the HD-DVD specification which is available to memebers of the DVD forum - it isn't free and it doesn't come with the jumpstart (although, if you can get a hold of it, Annex X is riveting).

  But, the biggest restictions you will face on a non-aacs protected disk is lack of ability to read/write to persistant storage and lack of network support. But if you don't need to download anything and don't need to save anything to p-stor for use later, then you're good to go.

  To test network delivered content you need either
  
  -. the Toshiba tools with software emulator
  
  - Sonic Simulator
  
  
  I streamed network trailers from http in the Sonic Simulator. It is easy.
  
  
  

• Ahoapap

  And if you happen to have a spec, the complete list is in Annex X.

  Hi,

  Everything related to network and persistent storage won't work without AACS.

  
  

• huysmans

  "Must the data that you want to stream also be encrypted with AACS "

  that is a good question. I have only streamed network content in the Sonic Simulator. It does not require AACS on your streamed content but then again it does not require AACS to test the Network API, whereas the player does.

  As for your first question, my testbed was a local http server in the office. So, yes

  The AACS rules are complicated, and this is not really the correct forum to discuss them.

  You can have unencrypted S-EVOBs on the network, but right now all advanced content (XML, script, PNG, etc.) must be AACS-encapsulated when you are in AACS mode. (And since you need to be in AACS mode to access the network, that means all network resources must be encapsulated).

  These restrictions are cumbersome and efforts are being made to relax them, but right now that's the lay of the land.

  
  
  

• dferraro

  So to recap it: with an AACS protected disc it is possible to stream an unencrypted EVOB
  from a network location

  I reviewed all docs that came with the JumpStart package, but could not find anything interesting. I assume that the 'spec' that you talk about is not part of this package If not, can you please provide more info
  
  

• kangalert

  That's what I was already afraid of. But how can you test this functionality on a real player (for instance the Toshiba HD-A1) if you are developing
