| 20090052313 | MANUFACTURING RECORD CARRIERS SUITABLE FOR POST-RECORDING - The present invention relates to a method and to an apparatus for manufacturing a record carrier having stored a content information in the form of a modulated bitstream | 02-26-2009 |
| 20090067311 | METHOD AND APPARATUS FOR RECORDING SECONDARY INFORMATION ON A RECORD CARRIER - The present invention relates to a method of recording secondary information on a record carrier, in particular on an optical record carrier, besides its content information, whereby it is possible to differentiate the record carrier from other record carrier bearing the same content information, for example by recording an individual identifier. The secondary information is recorded by: forming at predetermined positions dummy patterns ( | 03-12-2009 |

| 20080317170 | Embedding a Secondary Information Signal in a Channel Data Stream - The present invention relates to a method and a corresponding device for embedding a secondary information signal in a channel data stream of encoded primary information signal. In order to make it more difficult for unauthorized persons or devices to retrieve the location of storage of the secondary information signal or its content itself a device is proposed according to the present invention comprising: | 12-25-2008 |
| 20090303848 | OPTICAL DISCS WITH IDENTIFICATION CODE - An individual code can be recorded on optical discs with post-recording techniques like for example laser-ablation. This normally requires the presence of an ad-hoc decoder in a corresponding playback apparatus. According to the invention this individual code is recorded by using an encoding scheme which is different from the encoding scheme proper of the user data but equal to the encoding scheme proper of control data already foreseen in the disc, like for example PIC in the case of a BD. In this way an ad-hoc decoder is no longer required and a suitable playback apparatus capable of acquiring individual code can be obtained with minimal modifications of an existing playback apparatus. | 12-10-2009 |
