- 10. The method of claim 1, further comprising:
recording the map information in a storage.
- 11. The method of claim 10, wherein in the recording step, the storage is either an internal memory or an optical disc.
- 12. The method of claim 1, further comprising:
accessing one of the object units based on the map information.
- 13. A recording medium for providing management information, comprising:
a plurality of object units stored on the recording medium, the object units representing groups of data of a digital data stream; and map information stored on the recording medium for accessing the data, wherein the map information includes access time information and object unit information associated with the object units.
- 14. The recording medium of claim 13, wherein the object unit information includes object unit size information and object unit presentation time information associated with each of the object units.
- 15. The recording medium of claim 14, wherein the object unit size information of an object unit identifies a size of that object unit.
- 16. The recording medium of claim 14, wherein the object unit presentation time information of an object unit identifies a playing time of that object unit.
- 17. The recording medium of claim 13, wherein the access time information includes a plurality of index numbers each associated with one of the object units.
- 18. The recording medium of claim 17, wherein the access time information further includes location information for each of certain object units.
- 19. The recording medium of claim 18, wherein the access time information further includes time duration information identifying a time duration between two start presentation time positions associated with the data.
- 20. The recording medium of claim 14, wherein the access time information includes a plurality of index numbers each associated with one of the object units.
- 21. The recording medium of claim 20, wherein the access time information further includes location information for each of certain object units, and time duration information identifying a time duration between two start presentation time positions associated with the data.
- 22. The recording medium of claim 13, wherein the recording medium is an optical disc.
- 23. An apparatus for providing management information, comprising:
means for grouping data of a digital data stream into a plurality of object units; and means for creating map information for accessing the data, wherein the map information includes access time information and object unit information associated with the object units.
- 24. The apparatus of claim 23, wherein the object unit information includes object unit size information and object unit presentation time information associated with each of the object units.
- 25. The apparatus of claim 24, wherein the object unit size information of an object unit identifies a size of that object unit.
- 26. The apparatus of claim 24, wherein the object unit presentation time information of an object unit identifies a playing time of that object unit.
- 27. The apparatus of claim 23, wherein the access time information includes a plurality of index numbers each associated with one of the object units.
- 28. The apparatus of claim 27, wherein the access time information further includes location information for each of certain object units.
- 29. The apparatus of claim 28, wherein the access time information further includes time duration information identifying a time duration between two start presentation time positions associated with the data.
- 30. The apparatus of claim 24, wherein the access time information includes a plurality of index numbers each associated with one of the object units.
- 31. The apparatus of claim 30, wherein the access time information further includes location information for each of certain object units, and time duration information identifying a time duration between two start presentation time positions associated with the data.
- 32. The apparatus of claim 23, further comprising:
means for recording the map information in a storage.
- 33. The apparatus of claim 32, wherein the storage is either an internal memory or an optical disc.
- 34. The apparatus of claim 32, further comprising:
means for accessing one of the object units based on the map information.
