Abstract: PURPOSE: An apparatus for converting a digital data stream format is provided to eliminate an inconvenience of controlling an optical disk apparatus in order to control the navigation operation of the optical disk apparatus. CONSTITUTION: In an apparatus for converting a digital data stream format, a partition part(56) divides and extracts a program stream and first navigation data which are incorporated in the digital data stream. An interpreter(88) interprets the extracted program stream to divide and interpret the program stream into second navigation data for system clock data, presentation data and a program reproduce control. An analyzer subdivides the divided and interpreted presentation data into each constituent data, and a timing controller generator(90) produces a reference time for a data packet transfer based on the system clock data. A PSI & CRC generator(86) converts the first and the second navigation data into additional data added into the data packet, and TS packizer & MUX(87) combines each constituent data and the additional data, and constructs the combined result into a data stream of a predetermined format based on the reference time.
