Abstract
A method and apparatus for recording time information for received digital data streams to be recorded on a recording medium such as a digital video disk and searching the recorded digital data streams using the time information. The format of the time information is the same as that of the time data in the navigation information and the time information is used as the low-unit time value of the arrival time of data stream in the case of data search. The error in the start position of each stream object unit, resulting from insufficient resolution of the packet arrival time format, is corrected without additional information indicative of the offset between the start time of a stream object unit and the time value obtained from incremental arrival time information, thereby enabling precise and fast data search capability and increasing recording efficiency.
