To effect a phased approach to enhanced security.

Copy-protected content material is screened for an indication of the availability of an enhanced version of a screening system, and an upgrade to the advanced screening system is forced by refusing to process the copy-protected content material until the upgrade is performed. When security standards change, and security techniques corresponding to the changed security standards are available for downloading to existing consumer products, newly published content material contains an indication to be executed. When the newly published content material is processed by an existing consumer device, the consumer device detects this indication of an available update, and prevents the processing of the newly published content material until the update is received.
