System renewability message transport

A method for transmitting content, the method comprising:

• providing a transport stream in which the content is embodied, wherein the transport stream comprises a first plurality of data packets, a second plurality of data packets, and a third plurality of data packets, wherein the providing of the transport stream is performed by at least one processor;
• wherein the first plurality of data packets includes data that form a first table,
• wherein each data packet of the second plurality of data packets comprises an identifier,
• wherein the identifier is referenced in the first table,
• wherein the second plurality of data packets includes data that form a data structure comprising a second table having a first field and a second field,
• wherein the first field is for containing an identity of one of a plurality of providers of copy protection technology, wherein the first field further is for enabling a creation of a plurality of instances of the second table when the second plurality of data packets includes a plurality of identities of the plurality of providers of copy protection technology, wherein each of the plurality of instances is for a different identity of the plurality of identities of the plurality of providers of copy protection technology,
• wherein the second field is for containing identities of a plurality of devices that are unauthorized for the use of content and wherein the plurality of devices are associated with the one of the plurality of providers of copy protection technology identified in the first field,
• wherein the third plurality of data packets includes the content, and
• wherein none of the packets of the first and second plurality of packets contains the content.

An article of manufacture for preventing a use of content by a plurality of devices that are unauthorized for the use of the content and that have identities, the article of manufacture being for use by another device having a processing unit, the article of manufacture comprising:

• at least one non-transitory computer-readable storage medium containing instructions that, when executed by the processing unit, cause the processing unit to perform a method comprising:
• selecting from a transport stream a first plurality of packets according to an identifier that is referenced in a first table,
• wherein each packet of the first plurality of packets includes the identifier,
• wherein the first plurality of packets comprises data that form a data structure comprising a second table having a first field and a second field,
• wherein the first field is for containing an identity of one of a plurality of providers of copy protection technology, wherein the first field further is for enabling a creation of a plurality of instances of the second table when the first plurality of packets includes a plurality of identities of the plurality of providers of copy protection technology, wherein each of the plurality of instances is for a different identity of the plurality of identities of the plurality of providers of copy protection technology,
• wherein the second field is for containing the identities of the plurality of devices that are unauthorized for the use of the content and wherein the plurality of devices are associated with the one of the plurality of providers of copy protection technology identified in the first field, and
• preventing the use of the content in accordance with the data in the first plurality of packets,
• wherein the transport stream further includes a second plurality of packets that includes the content, and
• wherein none of the packets of the first plurality of packets contains the content.

A system for preventing a use of content by a plurality of devices that are unauthorized for the use of the content and that have identities, the system comprising:

• another device having a processing unit operable to execute software routines, and
• programming logic executed by the processing unit, wherein the programming logic comprises:
• means for providing a transport stream in which the content is embodied,
• wherein the transport stream comprises a first plurality of data packets, a second plurality of data packets, and a third plurality of data packets;
• wherein the first plurality of data packets includes data that forms a first table,
• wherein each data packet of the second plurality of data packets comprises an identifier,
• wherein the identifier is referenced in the first table,
• wherein the second plurality of data packets includes data that forms a data structure comprising a second table having a first field and a second field,
• wherein the first field is for containing an identity of one of a plurality of providers of copy protection technology, wherein the first field further is for enabling a creation of a plurality of instances of the second table when the second plurality of data packets includes a plurality of identities of the plurality of providers of copy protection technology, wherein each of the plurality of instances is for a different identity of the plurality of identities of the plurality of providers of copy protection technology,
• wherein the second field is for containing the identities of the plurality of devices that are unauthorized for the use of the content and wherein the plurality of devices are associated with the one of the plurality of providers of copy protection technology identified in the first field,
• wherein the third plurality of data packets includes the content, and
• wherein none of the packets of the first and second plurality of packets contains the content.

A data structure stored on a non-transitory computer-readable storage medium, wherein the data structure is for use with a first table, for use with identities of a plurality of devices that are unauthorized for use of content, and for use with an identity of at least one of a plurality of providers of copy protection technology, the data structure comprising:

• a second table having a first field and a second field,
• wherein the second table is formed from a plurality of packets of an MPEG-type transport stream, wherein each of the plurality of packets includes an identifier, wherein the identifier is referenced in the first table,
• wherein the first field of the second table is for containing the identity of the at least one of the plurality of providers of copy protection technology, wherein the first field further is for enabling a creation of a plurality of instances of the second table when the plurality of packets includes a plurality of identities of the plurality of providers of copy protection technology, wherein each of the plurality of instances is for a different identity of the plurality of identities of the plurality of providers of copy protection technology;
• wherein the second field of the second table is for containing the identities of the plurality of devices that are unauthorized for the use of the content, wherein the plurality of devices are associated with the at least one of the plurality of providers of copy protection technology identified in the first field.
