A stream data recording device is provided for recording stream data on a recording medium. The stream data recording device includes a stream reception/analysis unit (), acquiring stream data from reception data, a a missing portion detection unit () detecting a missing packet portion in the acquired stream data, a section information generation unit () generating time information specifying the duration of the unreceivable section including the packets whose missing portion has been detected and position information specifying the position of the unreceivable section in the stream data, and a recording unit () recording the acquired stream data, the generated time information and position information on the recording medium. Thus, even if the recording-target stream data is missing a portion during reception of the stream data, the data can be correctly played back from the seek time specified by a user.

When recording stream data, index information and time correction information are recorded in correspondence with the stream data. The index information specifies a position of an invalid section in the stream data. The time correction information specifies a time which, supposing that a PCR included in the invalid section was able to be got, a time clock would have shown in synchronization with the PCR. When reproducing the stream data recorded together with the time correction information and the index information, at a position where the invalid section ends, the time clock can be set to a time intended by a broadcasting system, by referencing the index information and the time correction information.
