Abstract
The control of access to content via a player system accessible by a plurality of users is described. A default profile is provided including filtering criteria, the filtering criteria describing at least one of characteristic of content permitted for all of the plurality of users and a characteristic of content prohibited for all of the plurality of users. Metadata associated with a selected content and the filtering criteria are compared, and access to the content is permitted or denied based on the comparison. Also, content is selected, the selected content having metadata linked thereto via a pointer. The metadata is obtained using the pointer. The metadata and filtering criteria are compared, the filtering criteria describing characteristics of at least one of permitted or prohibited content. Access to the content is permitted or denied based on the comparison.
