Abstract:
1. A stream data recording device that records stream data including pieces of clock reference information, the stream data recording device comprising: a getting unit operable to get the stream data; a time clock unit operable to count a time synchronously with a time shown by each piece of clock reference information; a detection unit operable to detect, in the got stream data, an invalid section where a part of packets of the stream data is missing; a generation unit operable to generate index information and time correction information, the index information specifying a position of an end of the invalid section in the stream data, and the time correction information being used for correcting the time of the time clock unit at the end of the invalid section, to a state identical to if the time clock unit synchronizes with a time shown by a piece of clock reference information included in the invalid section; and a recording unit operable to record the generated index information and time correction information in correspondence with the got stream data.
