Abstract

A method of sharing a function via a network includes selecting a second device having a shared function desired by a first device from among at least one device connected to the network, linking the first device with the second device via the network, transmitting original multimedia content from the first device to the second device via the network, and performing the shared function with respect to the original multimedia content in the second device and transmitting result data of the performing of the shared function to the first device via the network.

Claims

1. A method of sharing a function between devices via a network, the method comprising:

receiving, by a first device, an instruction from a user to play multimedia content,

selecting, by the first device, from among a plurality of devices connected to the network, a second device that is capable of processing the multimedia content by at least one of encoding the multimedia content in a format supported by the first device and decoding the multimedia content;

transmitting the multimedia content with information indicating that processing to be performed by the second device is one of the encoding and the decoding the multimedia content, from the first device to the second device via the network; and

receiving, by the first device, the processed multimedia content from the second device via the network,

wherein the first device selects the second device and transmits the multimedia content to the second device when the first device is unable to play the multimedia content, and

wherein the processed multimedia content is playable by the first device.

2. The method of claim 1, wherein selecting the second device comprises:

searching for at least one device capable of processing the multimedia content from among the plurality of devices connected to the network; and

selecting the second device from among the at least one device found based on the search.

3. The method of claim 1, wherein selecting the second device comprises:

receiving a device property list with respect to a function of each of the plurality of devices connected to the network; and

selecting the second device in reference to the device property list.

4. The method of claim 1, wherein, in transmitting the multimedia content, the multimedia content is converted to a Transport Stream (TS) and the TS is transmitted to the second device.

12. A non-transitory computer readable recording medium having recorded thereon a computer program for implementing the method of claim 1.

5. An apparatus for sharing a function with an external device via a network, the apparatus comprising:

a processor configured to;

receive an instruction from a user to play multimedia content; and

select the external device from among a plurality of devices connected to the network, the external device being capable of processing the multimedia content by at least one of encoding the multimedia content in a format supported by the apparatus and decoding the multimedia content; and

a transmitter-receiver configured to;

transmit, to the external device via the network, the multimedia content with information indicating that the processing to be performed by the external device is one of the encoding and the decoding the multimedia content; and

receive the processed multimedia content from the external device via the network,

wherein the processed multimedia content is playable by the apparatus, and

wherein the processor selects the external device and the transmitter-receiver transmits the multimedia content to the external device when the apparatus is unable to play the multimedia content.

6. The apparatus of claim 5, wherein the processor is further configured to receive a device property list with respect to functional capabilities of each of the plurality of devices connected to the network and select the external device in reference to the received device property list.

7. The apparatus of claim 5, further comprising an output unit configured to play the processed multimedia content received by the transmitter-receiver.

8. The apparatus of claim 5, further comprising a storage unit configured to store the processed multimedia content received by the transmitter-receiver.

9. The apparatus of claim 5, further comprising an output unit configured to display a user interface for the user to select the external device from among the plurality of devices and select whether the processing to be performed by the external device is encoding or decoding the multimedia content.

10. A system for sharing a function between devices via a network, the system comprising a first device and a second device,

wherein the first device is configured to:

receive an instruction from a user to play multimedia content;

select the second device from among a plurality of devices connected to the network, the second device being capable of processing the multimedia content, and the processing the multimedia content including at least one of encoding the multimedia content in a format supported by the first device and decoding the multimedia content; and

transmit the multimedia content with information indicating that processing to be performed by the second device is one of the encoding and the decoding the multimedia content, to the second device via the network, and

the second device is configured to;

process the multimedia content based on the received information; and

transmit the processed multimedia content to the first device, the processed multimedia content being playable by the first device,

wherein the first device selects the second device and transmits the multimedia content to the second device when the first device is unable to play the multimedia content.

11. The system of claim 10, further comprising a relay unit configured to link the first device with the second device, manage a device property list with respect to functional capabilities of each of the plurality of devices connected to the network and provide, to the first device, either all of the device property lists or a device property list corresponding to a specific device capable of processing the multimedia content.
