Abstract (en)
[origin: WO03058618A1] The invention relates to a cryptographic module for a receiver, for the storage and playback of copy-protected electronic tone and image media which is protected in terms of use. The legal extent of use for the receiver is regulated and maintained by means of said module. To this end, the cryptographic module of the receiver decodes or decrypts fully or partially encoded or encrypted data contents of electronic tone and image media, or keys for decoding said data contents, observing rights of use and conditions of use, and then re-encodes or encrypts said data contents or keys for the purpose of storage or playback, such that license fees can be based on use.
