Memory database creation system for encrypted program material

摘要

A memory database creation system for encrypted program material in which received encrypted material is first descrambled or decrypted and parsed to allow the generation of location identifiers for portions of the material. Once parsed, the location identifiers are stored in a database in a receiver and the material is again encrypted at the receiver prior to storage in memory. Typically, the steps of the method and system are performed at one instant thereby preventing unauthorized access to the material when it is in a descrambled or decrypted form.
