Abstract

A method and apparatus are provided for accessing an Internet storage. In the method, access to a home storage is controlled, and an internet storage which has higher access reliability than the home storage is accessed, if the access to the home storage is not available. Accordingly, even when the home storage is not in operation, it is possible to obtain content and meta data of the content.

Claims

1. A method of accessing storage comprising:

controlling access to a first storage; and

accessing a second storage having higher access reliability than the first storage, if the access to the first storage is not available.

2. The method of claim 1, wherein the first storage is located in a home network, and the second storage is located in the Internet.

3. The method of claim 1, wherein during the accessing the second storage, if it is detected that the access of the server module to the first storage is not available, the server module accesses the second storage instead of the first storage.

4. The method of claim 1, wherein during the controlling the access to the first storage, the access to the first storage is controlled by calling an application program interface (API) which performs an operation to gain access to the first storage, and

during the accessing the second storage, the second storage is accessed by executing the API for the second storage instead of the first storage, in response to the calling the API.

5. The method of claim 4, wherein the API is a universal plug and play (UPnP) action.

6. A storage access apparatus comprising:

a control module which controls access to a first storage; and

a server proxy which accesses a second storage having higher access reliability than the first storage, if the access to the first storage is not available.

7. A computer readable medium having recorded thereon a computer program for executing a method of accessing storage, the method comprising:

controlling access to a first storage; and

accessing a second storage having higher access reliability than the first storage, if the access to the first storage is not available.

8. A method of accessing storage comprising:

performing an operation of a server proxy as a server accessing a first storage in place of a server module accessing the first storage; and

accessing a second storage having higher access reliability than the first storage, corresponding to the operation performed by the server proxy.

9. The method of claim 8, wherein the first storage is located in a home network, and the second storage is located in the Internet.

10. The method of claim 8, further comprising:

transforming access control from a format according to first standards used for the first storage into a format according to second standards used for the second storage,

wherein during the accessing the second storage, the second storage is accessed by using the access control transformed into the format according to the second standards.

11. The method of claim 10, wherein during the transforming the access control, an application program interface (API) for gaining access to the first storage in the format according to the first standards is transformed into the format according to the second standards for gaining access to the second storage, and

during the accessing the second storage, the second storage is accessed by executing the API in the format according to the second standards.

12. The method of claim 10, further comprising:

obtaining a result of the accessing the second storage; and

transforming the result of the accessing the second storage from the format according to the second standards into the format according to the first standards of accessing the first storage.

13. The method of claim 10, wherein the first standards are universal plug and play (UPnP) standards, and the second standards are Distributed Hash Table (DHT) standards.

14. A storage access apparatus comprising:

a first server module which acts as a server accessing a first storage in place of an existing server module accessing the first storage; and

a second server module which accesses a second storage having higher access reliability than the first storage, corresponding to an operation performed by the first server module.

15. A computer readable medium having recorded thereon a computer program for executing a method of accessing storage, the method comprising:

performing an operation of a server proxy as a server accessing a first storage in place of a server module accessing the first storage; and

accessing a second storage having higher access reliability than the first storage, corresponding to the operation performed by the server proxy.

16. A method of accessing storage comprising:

receiving access control to a storage in a format according to first standards;

transforming the access control to the storage from the format according to the first standards into a format according to second standards; and

accessing the storage using the access control having the transformed format according to the second standards.

17. The method of claim 16, wherein the storage is located in the Internet.

18. The method of claim 16, wherein during the transforming the access control, an application program interface (API) for gaining access to the storage in the format according to the first standards is transformed into the format according to the second standards, and

during the accessing the storage, the storage is accessed by executing the API in the format according to the second standards.

19. The method of claim 16, further comprising:

obtaining a result of the accessing the storage in a format according to the second standards; and

transforming the result of the accessing the storage from the format according to the second standards into the format according to the first standards.

20. The method of claim 16, wherein the first standards are universal plug and play (UPnP) standards, and the second standards are Distributed Hash Table (DHT) standards.

21. A storage access apparatus comprising:

a first server module which receives access control to a storage in a format according to first standards;

a transformer which transforms the access control to the storage from the format according to the first standards into a format according to second standards; and

a second server module which accesses the storage using the access control having the transformed format according to the second standards.

22. A computer readable medium having recorded thereon a computer program for executing a method of accessing storage, the method comprising:

receiving access control to a storage in a format according to first standards;

transforming the access control to the storage from the format according to the first standards into a format according to second standards; and

accessing the storage using the access control having the transformed format according to the second standards.
