A system and method to facilitate editing of content data. An update metadata identification block identifies metadata that is affected (or must be updated) by destructive edit processing by a material data destructive edit processing block. If the metadata is required for updating, a realtime metadata update block updates realtime metadata and a nonrealtime metadata update block updates nonrealtime metadata in correspondence with the destructive edit processing. A proxy data update block updates proxy data. A clip information file update block updates a clip information file. A clip write block records the data of each clip updated by the above-mentioned processing to an optical disc.
