Abstract
Copy-protected content material is screened for an indication of the availability of an enhanced version of a screening system and forcing an upgrade to the advanced screening system by refusing to process the copy-protected content material until the upgrade is preformed. When security standards change, and corresponding security techniques are available for downloading to existing consumer devices, newly published content material will contain an indication to that effect. When the newly published content material is processed by an existing consumer device, the consumer device will detect this indication of an available update, and will prevent the processing of this newly published content material until the update is received. In this manner, a phased approach to enhanced security can be effected.
