Method and apparatus for reproducing data using management data

A method of reproducing data from a recording medium with a reproducing device, the recording medium including a plurality of stream object units and reproduction management information recorded thereon, the method comprising:

• reproducing, via the reproducing device, at least one of the plurality of stream object units from the recording medium based on the reproduction management information,
• wherein the plurality of stream object units and the reproduction management information recorded on the recording medium
• include recorded stream units of a digital data stream along with their arrival time references representing the arrival times of the received stream units on the recording medium,
• the received stream units being grouped into the plurality of stream object units of a predetermined size, such that a maximum search time for a stream object unit is almost uniform among the recorded stream object units, and
• the reproduction management information being created and recorded regarding the stream object units on the recording medium.

A non-transitory recording medium including data to be read by a reproducing device, the recording medium comprising:

• stream units of a digital data stream along with their arrival time references representing the arrival times of the stream units;
• the stream units being grouped into stream object units of a predetermined size, such that a maximum search time for a stream object unit is almost uniform among the stream object units;
• and
• reproduction management information for reproducing the stream object units
• wherein the reproducing device reads the reproduction management information form the recording medium, and reproduces at least one of the plurality of stream object units from the recording medium based on the read reproduction management information.

A reproducing device, comprising:

• a reading unit configured to read at least one of a plurality of stream object units recorded on a recording medium;
• and
• a reproducing unit configured to reproduce the read at least one the plurality of stream object units based on a reproduction management information,
• wherein the plurality of stream object units and the reproduction management information recorded on the recording medium include stream units of a digital data stream along with their arrival time references representing the arrival times of the stream units on the recording medium, the stream units being grouped into the plurality of stream object units of a predetermined size, such that a maximum search time for a stream object unit is almost uniform among the stream object units.
