20080226067 | Method and Circuit for Encrypting a Data Stream - 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. | 09-18-2008 |
