Abstract:
A method for searching recorded digital data streams, comprising the steps of:(a) retrieving search time information comprising count values counted at constant time intervals while each stream object unit is recorded, each stream object unit having a predetermined number of transport stream units; (b) accessing a stream object unit containing requested search time with reference to the retrieved search time information; (c) retrieving reference information on arrival time added to the start transport stream unit of the accessed stream object unit; (d) determining the arrival time of the start transport stream unit, using the retrieved arrival time reference information and a time value calculated from the search time information corresponding to the accessed stream object unit; and (e) compensating the determined arrival time based upon comparison between the retrieved arrival time reference information and the search time information corresponding to the accessed stream object unit, wherein said step (e) comprises: (e2) judging whether the arrival time reference information added to each transport stream unit has been reset between the start time of the accessed stream object unit and the time value calculated from the search time information corresponding to the accessed stream object unit.
