Patent ID: 8014484

Claim:
A stream data reproducing device that reads stream data including pieces of clock reference information from a recording medium and reproduces the stream data, the stream data reproducing device comprising: a reading unit operable to read the stream data; a time clock unit operable to count a time synchronously with a time shown by each piece of clock reference information; an information getting unit operable to get index information and time correction information, the index information specifying a position, in the stream data, of an invalid section where a part of the stream data was missing, and the time correction information being used for correcting the time of the time clock unit; a resetting unit operable to reset the time clock unit based on the time correction information, when performing reproduction at the position specified by the index information; and a reproduction control unit operable to reproduce a frame in the stream data at a predefined presentation time, based on the time of the time clock unit; wherein the resetting unit resets the time clock unit when judging that the piece of clock reference information included in the invalid section shows a discontinuous time for synchronization of the time clock unit.
