    摘要: 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 optical disc reader jumps from the start sector (33) to the first target sector using a cross track mode.

    摘要: A record carrier for storing at least one stream of linked content cells thereon, which linking is performed based on navigation data. The record carrier includes modified navigation data and/or a stream arrangement of at least one stream of linked content cells, so that an access of the at least one stream of linked content cells on the record carrier under consideration of the navigation data is not disturbed, whereas a generally linear access of the at least one stream of linked content cells on the record carrier is disturbed.

    摘要: 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.
