<p>The present invention relates to a digital data stream recording method. The present digital data stream recording method creates an additional empty stream object unit (SOBU) with only stuffing packets, if transport packets, received before a counted incremental packet arrival time for a SOBU exceeds a predetermined maximum incremental packet arrival time defined in a provisional standard related with a treamer, do not compose a single complete SOBU because the inpt bit rate of transport packets is so low that a SOBU is not fully written with transport packets within the maximum incremental time, and writes the time difference between the counted incremental packet arrival time and the maximum time in a mapping list entry associated with the created empty SOBU. Accordingly, an incremental time sum calculated from the mapping list is exactly matched with real incremental time counted for associated SOBUs, therefore, a target position can be exactly found with the incremental time inforamtion written in the mapping list.</p> |
