Apparatus, systems, and methods for checking if a receiver is on a revocation list based on SRMs of DVDs

An article comprising a non-transitory medium storing instructions that enable a processor-based system to:

• process, using a processor included in the system, privilege renewability content, wherein (a) the system is to transfer protected content to a receiver device and (b) the renewability content is to include first and second type renewability content portions that respectively comprise first and second unique privilege-revoked identifiers for receiver devices;
• store, in a memory coupled to the system, the first portion but not the second portion based on whether the system is a first type system, wherein first type devices have less memory capacity to store privilege renewability content than second type devices;
• obtain a unique first identifier for a first receiver device compliant with a version of a content protection protocol;
• obtain a unique second identifier for a second receiver device compliant with another version of the content protection protocol;
• and
• send the protected content from the system to both receiver devices based on determining the first and second identifiers are not included in the privilege renewability content.

An apparatus comprising:

• a processor to process and update privilege renewability content, wherein (a) the apparatus is to transfer protected content to a receiver device and (b) the renewability content is to include first and second type renewability content portions that respectively comprise first and second unique privilege-revoked identifiers for receiver devices;
• and
• a memory, coupled to the processor, to store the first and second portions based on whether the apparatus is a second type apparatus, wherein first type devices have less memory capacity to store privilege renewability content than second type devices;
• wherein the renewability content includes a format that is scalable to operate with source devices of differing types and interoperable to operate with receiver devices compliant with differing content protection protocol versions.
