Abstract

An electronic apparatus is capable of transferring contents on a cloud system to a device connected to a DLNA. In a method for operating a client on the cloud service system, a stream meta data table including information of one or more contents is received from a server. Meta data of contents selected from the contents are converted such that the meta data coincide with a format used by a device selected from one or more devices connected to a network. The selected contents are streamed from the server and transferred to the selected device.

Claims

1. A method for operating an electronic apparatus on a cloud service system, the method comprising:

receiving a stream meta data table comprising information of one or more contents from a server;

converting meta data of contents selected from the contents such that the meta data coincide with a format used by a client selected from one or more clients connected to a network; and

streaming the selected contents from the server to transfer the same to the selected client.

2. The method of claim 1, further comprising:

determining a kind of a protocol provided by the server;

requesting the server to GET the determined protocol;

receiving a response message of the determined protocol from the server; and

requesting the server to transmit the stream meta data table.

3. The method of claim 2, further comprising:

determining meta data information of one or more contents provided by the server.

4. The method of claim 3, wherein determining the meta data information of one or more contents provided by the server comprises:

determining the meta data information of one or more contents by analyzing the received response message of the protocol or using an Application Program Interface (API) provided by a cloud.

5. The method of claim 1, further comprising:

determining accessibility of the selected client.

6. The method of claim 5, wherein determining accessibility of the selected client comprises:

transmitting a ProtocolInfo message to the selected client; and

receiving a response signal to the ProtocolInfo message from the selected client.

7. The method of claim 1, wherein the network comprises a Digital Living Network Alliance (DLNA).

8. The method of claim 1, wherein converting the meta data of the contents selected from the contents such that the meta data coincide with the format used by the client selected from one or more clients connected via the network comprises:

determining that one of the one or more contents has been selected;

determining meta data of the selected contents among meta data information of the determined one or more contents; and

converting the determined meta data such that the meta data coincide with a format used by the selected client connected to a Digital Living Network Alliance (DLNA).

9. The method of claim 8, wherein converting the determined meta data such that the meta data coincide with the format used by the selected client connected to the DLNA comprises:

converting at least one of an Uniform Resource Identifier (URI), a type, a size, duration, and a thumbnail URI of contents among the determined meta data such that the meta data coincide with the format used by the selected client.

10. The method of claim 8, further comprising:

converting a public Internet Protocol (IP) address, which is an address on a web browser where the one or more contents are post, to a private IP address; and

transmitting a private IP Uniform Resource Identifier (URI) comprising the converted IP address and the converted meta data to the selected client.

11. The method of claim 1, wherein streaming the selected contents from the server to transfer the same to the selected client comprises:

pushing the streamed contents from the server such that the streamed contents are reproduced by the selected client.

12. The method of claim 1, wherein streaming the selected contents from the server to transfer the same to the selected client comprises:

pulling the streamed contents from the server such that the streamed contents are reproduced by the selected client.

13. A method for operating a client on a cloud service system, the method comprising:

receiving meta data coinciding with a format of a network in use from an electronic apparatus; and

streaming arbitrary contents from the electronic apparatus.

14. The method of claim 13, further comprising:

determining accessibility via the electronic apparatus.

15. The method of claim 14, wherein determining accessibility via the electronic apparatus comprises:

receiving ProtocolInfo message from the electronic apparatus; and

transmitting a response signal to the ProtocolInfo message to the electronic apparatus.

16. The method of claim 13, wherein receiving the meta data coinciding with the format of the network in use from the electronic apparatus comprises:

receiving the meta data and a private URI of arbitrary contents together.

17. The method of claim 13, wherein the network comprises a Digital Living Network Alliance (DLNA).

18. An electronic apparatus on a cloud service system, the apparatus comprises:

a protocol extractor configured to receive a stream meta data table comprising information of one or more contents from a server;

a meta data generator configured to convert meta data of selected content among the contents such that the selected contents coincides with a format used by a client selected among one or more clients connected to a network; and

a Digital Living Network Alliance (DLNA) Digital Media Controller (DMC) configured to stream the selected content from the server to transfer the selected content to the selected client.

19. The apparatus of claim 18, wherein the protocol extractor is configured to:

determine a kind of a protocol provided by the server,

request the server to GET the determined protocol,

receive a response message of the determined protocol from the server, and

request the server to transmit the stream meta data table.

20. The apparatus of claim 19, further comprising:

a meta data generator configured to determine meta data information of the one or more contents provided by the server.

21. The apparatus of claim 20, wherein the meta data generator is configured to determine the meta data information of one or more contents by analyzing the received response message of the protocol or using an Application Program Interface (API) provided by a cloud.

22. The apparatus of claim 18, wherein the DLNA DMC is configured to determine accessibility of the selected client.

23. The apparatus of claim 22, wherein the DLNA DMC is configured to transmit a ProtocolInfo message to the selected client and receives a response signal to the ProtocolInfo message from the selected client.
