Abstract:
1. Apparatus for copying the data content of a source multi-session DVD-storage medium to a destination multi-session DVD-storage medium, wherein the data content of the source multi-session DVD-storage medium is organized in a plurality of sequential sessions having a second session being adjacent and following a first session, wherein the second session includes a file allocation table and at least one file, the file allocation table storing at least the physical start address of each file within the session, and wherein an address space between two adjacent sessions on said source multi-session DVD-storage medium is different from an address space between two adjacent sessions on said destination multi-session DVD-storage medium, the apparatus comprising: a read unit for reading the plurality of sequential sessions from said source storage medium, an address converting unit adapted to analyze the file allocation table of the second session of the source multi-session DVD-storage medium and to apply a predetermined address offset to each physical start address in the file allocation table of the second session to obtain a converted file allocation table of the second session, wherein the predetermined address offset depends on a difference between an address space between two adjacent sessions on said source multi-session DVD-storage and an address space between two adjacent sessions on said destination multi-session DVD-storage, a write unit for writing the plurality of sequential sessions on said destination storage medium, wherein the write unit is adapted to copy the plurality of sequential sessions, wherein the file allocation table of the second session is replaced by the converted file allocation table of the second session, and a controller unit for controlling said read unit and said write unit.
