Abstract:
1. An editing device configured to dub stream data stored in a source recording medium to a destination recording medium, comprising: a recording unit configured to record data in said destination recording medium; a recording control unit configured to control said recording unit in recording specified ranges of the stream data to the destination medium, based on source management information stored in the source recording medium; and a management information generating unit configured to generate destination management information based on a predetermined relationship between the specified ranges of the stream data and said source management information, which corresponds to the specified ranges of the stream data, wherein the destination management information includes: when dubbing the specified ranges of the stream data, said management information generating unit determines whether a seamless connection is to be performed between first and second ranges of the specified ranges based on a comparison of timing information corresponding to the first and second ranges, the timing information being included in the source management information, and generates connection state information indicating a seamless connection state between the first and second ranges when the seamless connection is determined to be performed; the recording control unit includes the generated connection state information, as additional management information that performs playback control to consecutively play the specified ranges of the stream data at frame timing on the destination medium, in the generated destination management information, and records the destination management information in said destination recording medium such that consecutive playback control between the first and second ranges is performed at the destination recording medium; and said management information generating unit determines whether the seamless connection is to be performed between said first range and said second range based on whether the playback start point of said first range is identical to said playback start point of said playback section data corresponding to the first range.
