Abstract: Method for converting non copy protected data into copy protected data. The non copy protected data includes data structure data, controlling data and content data. The content data are embedded into data structures defined by the data structure data, and are processed using the controlling data. The method includes transferring part of the data structure data or the controlling data via a first network, from a first to a second network location, generating modified data structure data or modified controlling data at the second network location based on the data structure/controlling data supplied to the second network location, transferring the modified data structure/controlling data via a second network from the second to a third network location, where the copy protected data is generated by embedding the content data into modified data structures based on the modified data structure data or by replacing the controlling data with the modified controlling data.

Abstract: An optical disc including: sectors each having a sector ID; a first area having a first set of sectors sequentially arranged on the disc according to their respective IDs; a second area having a second set of sectors sequentially arranged on the disc according to their respective IDs, the second area being located after the first area in respect of a disc scan direction, the second area including all information needed for playback of the entire disc and having at least one sector ID which duplicates that of a sector in the first set of sectors.

Abstract: An optical disc (11 to 18) having sectors (3) each having a sector ID further comprises: a first area (4) having a first set of sectors (313-315) sequentially arranged on the disc (11 to 18) according to their respective IDs, a second area (5) having a second set of sectors (316-318) sequentially arranged on the disc (11 to 18) according to their respective IDs, the second area (5) being located after the first area (4) in respect of a disc scan direction (B) and having at least one sector ID which duplicates that of a sector in the first set of sectors, a start sector (33) located before the first area (4), and navigation data indicating to an optical disc reader, after having read the start sector (33), to displace its pickup reader device to a first target sector (316, 317, 352) having a sector ID of one of the sectors of the second area (5) or of a sector located after the second area (5), wherein the number of sectors between the start sector (33) and the first target sector is chosen such that the

Abstract: The invention relates to a method for effectively converting non copy protected data (1) into copy protected data (5). The non copy protected data (1) comprises data structure data, controlling data and content data. The content data are embedded into data structures defined by the data structure data, and are processible by using the controlling data.
