The specification was created by the DVD Forum and is available from the DVD Formart/Logo Licensing Corporation. For more information, visit: http://www.dvdfllc.co.jp/format/f_nosbsc.html.
Where can I find a list of all the ECMASCript objects and methods used in advanced interactivity for HD DVD? Annex Z of the DVD Specifications for High Definition VIDEO goes into depth on the objects, methods, members, exceptions, and external specification references used in advanced content.
An object model diagram is also available in Visio and .png format in the Documentation directory when you install the Interactivity Jumpstart Kit.
What is an ACA?
ACAs are archive files. By grouping your application files into a single ACA file, you reduce the number of seeks required by the laser and more efficiently utilize the player's filecache. For more information on ACA files, read http://blogs.msdn.com/amyd/archive/2007/05/09/acas-are-your-friend.aspx or http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1823600&SiteID=1
What functionality is restricted on a non-AACS HD DVD?
Networking and use of persistent storage is currently restricted to AACS discs. In the future, application signing may allow these features on non-AACS discs. Further details on these restrictions can be found in Annex X of the DVD Specifications for High Definition VIDEO.
