Abstract

A method and apparatus for reproducing data from a recording medium are disclosed. The method and apparatus calls for downloading data associated with data read from the recording medium. The downloaded data is stored in a local storage using an organization ID directory. The downloaded data from the local storage and the data from the recording medium are ultimately bound together to form a virtual package.

Claims

1. An apparatus for reproducing data of a recording medium, the apparatus comprising:

a pickup unit configured to read data from the recording medium;

a local storage configured to store downloaded data associated with the recording medium, the local storage storing a 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; and

a controller configured to

check a disc ID of the recording medium,

read data corresponding to the disc ID from the local storage,

bind the read data with data recorded in the recording medium to form a virtual package.

2. The apparatus of 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 apparatus of claim 1, wherein the local storage further stores binding information for the binding.

4. The apparatus of claim 1, wherein the local storage stores a directory for a content provider providing the recording medium and the downloaded data.

5. The apparatus of claim 4, wherein the directory includes a directory for the recording medium.

6. A method for reproducing data of a recording medium comprising

downloading data associated with the recording medium in a local storage;

storing a local storage file system including the downloaded data in the 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;

checking a disc ID of the recording medium;

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

binding the read data with data recorded in the recording medium to form a virtual package.

7. The method of claim 6, 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.

8. The method of claim 6, wherein the local storage further stores binding information for the binding.

9. The method of claim 6, wherein the local storage stores a directory for a content provider providing the recording medium and the downloaded data.

10. The method of claim 9, wherein the directory includes a directory for the recording medium.
