a third processor employing a third protection scheme for external outputs not protected by a digital rights management system, wherein said third protection scheme includes one or more of:

specifying copy protection information separately for one or more analog outputs, one or more digital uncompressed outputs and one or more digital compressed outputs;

specifying a CGMS (Copy Generation Management System) Copy protection state;

specifying MACROVISION parameters for one or more analog outputs; and

specifying if a particular type of output is allowed at all, and disabling the particular type of output if the particular output type is not allowed.

11. The apparatus ( 190 ) according to claim 10 , wherein said first protection scheme ( 160 ) includes:

specifying ( 161 ) whether a copy of said one or more files is allowed to be stored anywhere within said single authorized domain;

specifying ( 162 ) whether said one or more files may be stored only on one or more specific devices within said single authorized domain; and

specifying ( 163 ), when said one or more files are being rendered, how many simultaneous rendering devices are permitted.

12. The apparatus ( 190 ) according to claim 11 , wherein said second protection scheme ( 170 ) includes:

specifying ( 171 ) if the one or more files may be copied to one or more other domains, wherein, for copies, explicitly identifying ( 172 ) one or more domains to which said copies are allowed, thereby preventing a copy operation to any unspecified domain;

specifying ( 173 ) if the one or more files may be moved to one or more other domains, wherein for moves, optionally allowing movement of said one or more files to any other domain of said one or more other domains;

specifying ( 174 ) a list of one or more specific domains to which content may be copied, wherein during content transfer to another domain preserving content rights; and

specifying ( 175 ) a list of one or more specific domains to which content may be moved, wherein during content transfer to another domain preserving content rights.

13. A computer readable medium ( 200 ) having stored therein instructions causing a processor ( 191 - 193 ) to implement a copyright protection method ( 150 ) for one or more files comprising:

employing a first protection scheme ( 160 ) for use within a single authorized domain ( 195 ), in which all interfaces ( 194 a - c ) are protected with a same digital rights management system;

employing a second protection scheme ( 170 ) for use in inter-domain file transfers; and

employing a third protection scheme ( 180 ) for external outputs ( 197 a - c ) not protected by a digital rights management system;

wherein said first protection scheme ( 160 ) includes:

specifying ( 161 ) whether a copy of said one or more files is allowed to be stored anywhere within said single authorized domain;
