Abstract

A recording medium, and a method and apparatus for reproducing data from the recording medium are disclosed. A disc package for effectively reproducing data having different attributes recorded in the recording medium, and a method and apparatus for reproducing data of the recording medium and data downloaded from a content provider (CP) are disclosed. A first case in which the CP transmits an updated management file, and a second case in which a disc player forms an updated management file are disclosed.

Claims

1. A method for reproducing data of a recording medium comprising the steps of:

downloading data associated with the recording medium;

storing a local storage file system including the downloaded data in a local storage, the local storage file system including an organization ID directory corresponding to a content provider, the organization ID directory including a disc ID directory corresponding to the recording medium;

binding the downloaded data with data recorded in the recording medium to form a virtual package; and

reproducing at least one of the data recorded in the recording medium and the downloaded data using the virtual package,

wherein the downloaded data includes at least one of an index file including a table listing at least one reproducing unit of the virtual package and an object file to be used in reproducing the data recorded in the recording medium along with the downloaded data;

checking a disc ID of the recording medium;

reading data corresponding to the disc ID from among the data stored in the local storage; and

forming the virtual package by binding the read data and the data recorded in the recording medium.

2. The method according to claim 1, wherein the virtual package includes a Java directory formed by a combination of a Java program file contained in the downloaded data and a Java program file recorded in the recording medium.

3. The method according to claim 1, wherein the local storage further stores binding information for the binding.

4. The method according to claim 1, wherein the binding and reproducing are performed by a virtual system.

5. The method according to claim 1, wherein the local storage stores a directory for a content provider providing the recording medium and the downloaded data.

6. The method according to claim 5, wherein the directory includes a directory for the recording medium.

7. The method according to claim 1, wherein the at least one of an index file and at least one of an object file have the same file names as those of an index and object file recorded in the recording medium.

8. The method according to claim 1, wherein the object file includes a command or program for reproducing data within the virtual package.

9. The method according to claim 1, wherein the object file is a movie object file.

10. The method according to claim 1, wherein the object file is a Java object file.
