SYSTEM FOR MANAGING PROPRIETARY DATA

摘要

A system (300) has access control according to a predefined data access format. A studio (32) provides content data and related proprietary data on a record carrier (34) to be rendered by a rendering device (39). In the system, applications (35) are executed on the device for manipulating the content data and related proprietary data. An access policy is set for each studio that controls access to said content data and related proprietary data. A cross access policy is set for a virtual entity (42), and at least part of the proprietary data (43) is made available according to the cross access policy of the virtual entity. Also a cross studio application (41) is provided that complies with the access policy of the virtual entity for accessing said data.
