    Abstract: Current legislation requires the possibility of encryption when storing television programmes received by broadcast. However, legacy playback apparatuses will not be able to play back such encrypted data in a regular way, but possibly in a wrong way. This may result in problems like damage of speakers. Therefore, the application intends to hide any of such possibly damaging streams by intentionally providing such streams with a wrong identification during the encryption process. The application provides among others a method and circuit for encryption and a method and circuit for decryption. The application is especially suitable for DVD recorders, but may also be employed for other video and/or audio recorders. The invention may even be used for encrypting non-audiovisual data.

    Abstract: A method of and source device (410) for authorizing access to content (425) by a sink device (400) in accordance with usage rights, the content being stored on a storage medium (420) controlled by the source device. The revocation status of the sink device is verified using the most recently issued revocation information that is available if the usage rights need to be modified as part of the authorization of access to the content, and using revocation information associated with the content stored on the storage medium, preferably the revocation information stored on the storage medium, otherwise. The revocation information on the storage medium, or only the part relating to the sink device, is optionally updated to the most recently issued revocation information if the usage rights need to be modified. Preferably this is done only if the result of the verification is that the sink device has been revoked.

    Abstract: A method, apparatus and signal for combining two robust watermarks, whereby a low complexity watermark is searched for first, and if not found, a second higher complexity watermark is searched for. The low complexity watermark is robust against a limited set of signal processing that can be expected by a "friendly user" under normal conditions. The second higher complexity watermark is robust against all kinds of malicious attacks.
