Abstract: Embodiments of the present invention relate to audiovisual content authoring methods and systems and in particular to novel menu systems and the production thereof, for example implemented for DVD-Video discs. In one aspect, the present invention relates to a method of authoring an audiovisual product, for example a DVD-Video disc, comprising the steps of providing audiovisual content, generating at least a first menu (505) and a second menu (510), each menu comprising at least one menu option (506, 511), arranging the first menu (505) to be displayed during playback of the audiovisual content and arranging a menu option (506) of the first menu to cause display of the second menu during playback of the audiovisual content. Such a method facilitates hierarchical menu generation for DVD-Videos and the like.

Abstract: Provided is a system and method for safeguarding digital objects consisting of digital assets. The system includes a unique identifier and an impairer in each digital asset, the impairer distinct from the unique identifier. A database is provided with a record of each unique identifier. A client is in communication with the database. The client is adapted to receive a subset of the digital assets and analyze each digital asset to determine the unique identifier embedded therein. The client is further adapted to query the database with the determined unique identifier to validate each received digital asset. In response to proper validation, the impairer is removed from the received digital asset. An associated method is also provided.

Abstract: Provided is a system and method for safeguarding digital objects consisting of digital assets. The system includes a unique identifier in each digital asset and a database with a record of each unique identifier, the database further structured and arranged to correlate at least two digital assets as distinctly related. A client is in communication with the database. The client is adapted to receive a subset of the digital assets and analyze each digital asset to determine the unique identifier embedded therein. The client is further adapted to query the database with the determined unique identifier to validate each digital asset, the validation further including confirmation of distinctly related digital asset received. An associated method is also provided.
