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.

First claim

What is claimed is:

1. A method to operate an electronic apparatus connected to a plurality of clients on a cloud service system, the method comprising:
determining a kind of a protocol provided by a server;
requesting the server to retrieve the protocol;
receiving a response message of the protocol from the server; and
requesting the server to transmit metadata comprising information on the one or more contents included in the server;
receiving, from the server, the metadata comprising the information on the one or more contents included in the server;
selecting, among the plurality of clients, a client which is to reproduce a selected content among the one or more contents;
in response to selecting the client, determining a usable format of the metadata by the selected client;
converting, to the determined usable format, a format of the received metadata of the selected content, wherein converting the format of the received metadata of the selected content to the determined usable format includes:
converting the format of the metadata of the selected content to the determined usable format;
transmitting, to the selected client, the metadata of the selected content with the converted format, the metadata being to be used to reproduce the selected content by the selected client; and
receiving the selected content from the server and transferring the selected content to the selected client using a Digital Living Network Alliance (DLNA) Digital Media Controller (DMC),

wherein the information on the one or more contents is determined by analyzing the received response message of the protocol or using an Application Program Interface (API) provided by the cloud service system.

2. The method of claim 1 , further comprising:
transmitting a Protocol Info message to the selected client; and
receiving a response signal in response to the Protocol Info message from the selected client.

3. The method of claim 1 , wherein the plurality of clients are connected to network comprising a Digital Living Network Alliance (DLNA).

4. The method of claim 1 , wherein converting the format of the metadata of the selected content to the determined usable format comprises:
converting at least one of an Uniform Resource Identifier (URI), a type, a size, duration or a thumbnail URI of contents among the metadata.

5. The method of claim 1 , further comprising:
converting a public Internet Protocol (IP) address to a private IP address, wherein the public IP address comprises an address on a web browser where the one or more contents are posted; and
transmitting a private IP Uniform Resource Identifier (URI) comprising the converted IP address and the converted metadata to the selected client.

6. The method of claim 1 , wherein transferring the selected content comprises:
pushing the received content from the server so that streamed content is reproduced by the selected client.

7. The method of claim 1 , wherein transferring the selected content comprises:
pulling the received content from the server so that streamed content is reproduced by the selected client.

8. An electronic apparatus connected to a plurality of clients on a cloud service system, the electronic apparatus comprises:
a protocol extractor configured to receive, from a server, metadata comprising information on one or more contents included in the server, wherein the protocol extractor is configured to:
determine a kind of a protocol provided by the server,
request the server to retrieve the protocol,
receive a response message of the protocol from the server, and
request the server to transmit the metadata comprising the information on the one or more contents included in the server;

a metadata generator configured to:
select, among the plurality of clients, a client which is to reproduce a selected content among the one or more contents;
in response to selecting the client, determining a usable format of the metadata by the selected client;
convert, to the determined usable format, a format of the received metadata of the selected content, wherein to convert the format of the received metadata of the selected content includes:
convert the format of the metadata of the selected content to the determined usable format; and
transmit, to the selected client, the metadata of the selected content with the converted format, the metadata being to be used to reproduce the selected content by the selected client; and
determine the information on the one or more contents by analyzing the received response message of the protocol or using an Application Program Interface (API) provided by the cloud service system; and

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

9. The electronic apparatus of claim 8 , wherein the DLNA DMC is configured to transmit a Protocol Info message to the selected client and receive a response signal in response to the Protocol Info message from the selected client.

10. The electronic apparatus of claim 8 , wherein a network comprises a Digital Living Network Alliance (DLNA).

11. The electronic apparatus of claim 8 , wherein the metadata generator is configured to convert at least one of an Uniform Resource Identifier (URI), a type, a size, duration, or a thumbnail URI of contents among the metadata.

12. The electronic apparatus of claim 8 , wherein the metadata generator is configured to:
convert a public Internet Protocol (IP) address to a private IP address, wherein the public IP address comprises an address on a web browser where the one or more contents are posted, and
transmit a private IP Uniform Resource Identifier (URI) comprising the converted IP address and the converted metadata to the selected client.

13. The electronic apparatus of claim 8 , wherein the metadata generator is configured to push the received contents from the server so that streamed contents are reproduced by the selected client.

14. The electronic apparatus of claim 8 , wherein the metadata generator is configured to pull the received contents from the server so that streamed contents are reproduced by the selected client.
