Abstract

An information storage medium of this invention comprises a first representation object, and a first time map wherein playback management information which controls simultaneous reproduction of the first representation object and a second representation object in at least a specific period includes first reference information to refer to the first time map, the first time map includes second reference information to refer to second management information including first management information about the first representation object, the first management information includes third reference information to refer to the first representation object, the playback management information includes fourth reference information to refer to a second time map, and the second time map has a data structure including fifth reference information to refer to the second representation object.

Claims

1. An information storage medium comprising:

a first representation object; and

a first time map

wherein playback management information which controls simultaneous reproduction of the first representation object and a second representation object in at least a specific period includes first reference information to refer to the first time map,

the first time map includes second reference information to refer to second management information including first management information about the first representation object,

the first management information includes third reference information to refer to the first representation object,

the playback management information includes fourth reference information to refer to a second time map, and

the second time map has a data structure including fifth reference information to refer to the second representation object.

2. An information reproducing apparatus for playing back an information storage medium which stores a first representation object and a first time map and in which playback management information which controls simultaneous reproduction of the first representation object and a second representation object in at least a specific period includes first reference information to refer to the first time map, the first time map includes second reference information to refer to second management information including first management information about the first representation object, the first management information includes third reference information to refer to the first representation object, the playback management information includes fourth reference information to refer to a second time map, and the second time map has a data structure including fifth reference information to refer to the second representation object, the information reproducing apparatus comprising:

a reproducing unit configured to reproduce information from the information storage medium; and

a playback control unit configured to reproduce the second time map using the reproducing unit and reproduce the second representation object on the basis of the fifth reference information included in the second time map.

3. An information reproducing method of playing back an information storage medium which stores a first representation object and a first time map and in which playback management information which controls simultaneous reproduction of the first representation object and a second representation object in at least a specific period includes first reference information to refer to the first time map, the first time map includes second reference information to refer to second management information including first management information about the first representation object, the first management information includes third reference information to refer to the first representation object, the playback management information includes fourth reference information to refer to a second time map, and the second time map has a data structure including fifth reference information to refer to the second representation object, the information reproducing method comprising:

reproducing the second time map; and

reproducing the second representation object on the basis of the fifth reference information included in the second time map.
