Method for configuring composite file structure for data reproduction, and method and apparatus for reproducing data using the composite file structure

A method for reproducing data, comprising:

• recognizing identification (ID) information of a recording medium recording main data;
• determining whether sub-data having the same ID as that of the recording medium is present in a local storage;
• configuring, at a device, a composite file structure for simultaneously reproducing the main data and the sub data if the sub data is present in the local storage;
• and
• reproducing the main data and the sub-data using the configured composite file structure,
• wherein the configured composite file structure includes a downloaded playlist for reproducing the main data and the sub data.

An apparatus for reproducing data, comprising:

• a pickup unit configured to read main data from a recording medium;
• a local storage configured to store sub data associated with the main data;
• a decoder configured to decode the main data and the sub data;
• and
• a controller configured to form a composite file structure and control the decoder using the configured composite file structure, such that the main data and the sub data are simultaneously reproduced,
• wherein the composite file structure includes a downloaded playlist for reproducing the main data and the sub data.

A method for reproducing data, comprising:

• recognizing identification (ID) information of a recording medium in which main data is recorded;
• determining whether sub data having the same ID as that of the recording medium is present in a local storage;
• forming, at a device, a composite file structure for reproducing the main data and the sub data;
• and
• reproducing the main data and the sub data using the configured composite file structure,
• wherein the forming a composite file structure includes substituting a playlist file recorded in the recording medium with a downloaded playlist file.

A method for reproducing data, comprising the steps of:

• recognizing identification (ID) Information of a recording medium in which main data is recorded, and determining whether sub data having the same ID as that of the recording medium is present in a local storage;
• forming, at a device, a composite file structure for reproducing the main data and the sub data;
• and
• reproducing the main data and the sub data using the configured composite file structure,
• wherein the forming a composite file structure includes adding a downloaded playlist file to the composite file structure.

An apparatus for reproducing data, comprising:

• a pickup unit configured to read main data from a recording medium;
• a local storage configured to store sub data associated with the main data;
• a decoder configured to decode the main data and the sub data;
• and
• a controller configured to form a composite file structure and control a decoding process of the decoder using the composite file structure,
• wherein the controller substitutes a playlist file recorded in the recording medium with a downloaded playlist file.
