Methods, systems and architectures for enhancing a user's DVD experience are described. In one embodiment, the physical structure (e.g. titles and chapters) of a DVD is ascertained and a playlist structure shell that represents the DVD's physical structure is built. Metadata associated with the DVD is acquired and used to populate the playlist structure shell. In some embodiments, the metadata can be acquired from a metadata source external to the DVD and/or remote from a computing device on which the DVD is being played. Remote locations can include, without limitation, those that are network- or Internet-accessible. Once the playlist structure shell is populated, it can be used to render a playlist associated with the DVD's video in an area of a user interface display. In some embodiments, a DVD's video can be rendered in a first area of the user interface display and the playlist can be rendered in a second area of the user interface display during at least some of the time that the DVD's video is rendered in the first area.

Systems and methods for enhancing a user's DVD experience

Methods, systems and architectures for enhancing a user's DVD experience are described. In one embodiment, the hierarchical structure (e.g. titles and chapters) of a DVD is ascertained and a corresponding playlist structure shell is built. Metadata associated with the DVD is acquired and used to populate the playlist structure shell. In some embodiments, the metadata can be acquired from a metadata source external to the DVD and/or remote from a computing device on which the DYD is being played. Remote locations can include, without limitation, those that are network- or Internet-accessible. Once the playlist structure shell is populated, it can be used to render a playlist associated with the DVD's video in an area of a user interface display.

Systems and methods for retrieving, viewing and navigating DVD-based content

In order to allow for security beyond revocation lists, a policy regarding when permissions may be granted (in the form of a rights document, e.g. a use license or a certificate) is enforced. When a request is made for a rights document, the requester submits an account certificate which includes certain metadata regarding the requester. This metadata is analyzed to determine whether it meets a specific policy before the request is granted. If the request is not granted, the cause of the rejection may be overcome, for example by updating or upgrading some system component (hardware or software) in the requesting system. In certain cases, such an update to overcome a policy-based rejection may be performed transparently to the user.

Enhancing digital rights management system security through policy enforcement

A first trusted component on a first computing device performs cryptography, evaluation, and enforcement and is tied thereto, and a first user-machine certificate associated with the first computing device is tied to a user. Correspondingly, a second trusted component on a second computing device performs cryptography, evaluation, and enforcement and is tied thereto, and a second user-machine certificate associated with the second computing device is also tied to the user. The first trusted component obtains the content for rendering on the first computing device by way of the first user-machine certificate and the license, and the second trusted component obtains the content for rendering on the second computing device by way of the second user-machine certificate and the same license.
