Abstract

A multimedia content redirection method is provided. The multimedia content redirection method reproduces media content at a sink node employing enhanced media reproduction performance by redirecting a current media content being reproduced to the sink node when the sink node, such as audio device or media player, capable of reproducing multimedia contents is discovered in a network while a source node such as mobile terminal is reproducing the media content in an ad-hoc network.

Claims

1. A multimedia content redirection method for redirecting a multimedia content to a remote sink node in proximity and reproducing the multimedia content at the sink node, comprising:

reproducing multimedia content locally;

searching a proximity for a sink node;

determining whether it is possible to redirect the multimedia content to the sink node;

establishing a connection to the sink node;

dynamically extending functions of the sink node; and

redirecting the multimedia content to the sink node.

2. The multimedia content redirection method as claimed in claim 1, wherein the dynamically extending the functions of the sink node comprises transmitting a necessary mobile code when the redirection is possible.

3. The multimedia content redirection method as claimed in claim 1, wherein the reproducing the multimedia content locally comprises:

reproducing the multimedia content using a local media player, and

storing component information comprising at least one of information relating to the multimedia content and information relating to the local media player, as log information.

4. The multimedia content redirection method as claimed in claim 2, wherein the searching the proximity for the sink node comprises determining whether at least one of a beacon message and a greeting message is received from the sink node.

5. The multimedia content redirection method as claimed in claim 4, further comprising:

requesting device information from the sink node; and

receiving the device information from the sink node.

6. The multimedia content redirection method as claimed in claim 5, wherein the device information comprises at least one of component information and a data type.

7. The multimedia content redirection method as claimed in claim 5, wherein the determining of whether it is possible to redirect the multimedia content comprises comparing the device information received from the sink node with stored device information.

8. The multimedia content redirection method as claimed in claim 7, wherein the determining of whether it is possible to redirect the multimedia content comprises:

transmitting a connection ready message to the sink node; and

determining whether the sink node requires the mobile code.

9. The multimedia content redirection method as claimed in claim 8, further comprising:

receiving a connection ready message from the sink node; and

transmitting at least one of a media player session information and a connection request message to the sink node.

10. The multimedia content redirection method as claimed in claim 1, wherein the dynamically extending of the functions of the sink node comprises connecting the multimedia content to a media player of the sink node.

11. The multimedia content redirection method as claimed in claim 2, wherein the mobile code comprises at least one of a CODEC, a transport protocol (TP), a format parser, a transmission control protocol (TCP), and a user interface.

12. The multimedia content redirection method as claimed in claim 3, further comprising:

determining that at least one of a beacon message and a live message is not received from the sink node within a time period after dynamically extending the functions of the sink node;

terminating the redirection and the connection to the sink node in relation with the multimedia content; and

executing a new connection to the local media player.

13. A multimedia content redirection method for receiving and reproducing a redirected multimedia content from a source node which locally reproduces the multimedia content, comprising:

receiving a connection ready message from the source node;

determining whether a function extension is required to receive a redirected multimedia content;

requesting and receiving a mobile code from the source node;

dynamically extending functions based on the received mobile code when the function extension is required;

connecting a media player to the multimedia content; and

receiving the redirected multimedia content from the source node.

14. The multimedia content redirection method as claimed in claim 13, further comprising:

reproducing the redirected multimedia content at the media player.

15. The multimedia content redirection method of claim 14, wherein the redirected media content is reproduced after the redirected multimedia content is received.

16. The multimedia content redirection method as claimed in claim 13, further comprising:

transmitting at least one of a beacon message and a greeting message to the source node;

receiving a device information request message from the source node; and

transmitting device information to the source node in response to the device information request message.

17. The multimedia content redirection method as claimed in claim 16, wherein the connection ready message is received from the source node after the transmitting of the device information to the source node.

18. The multimedia content redirection method as claimed in claim 13, further comprising transmitting a connection ready message to the source node after the functions are dynamically extended.

19. The multimedia content redirection method as claimed in claim 18, further comprising receiving media player session information of the source node from the source node after the connection ready message is transmitted to the source node.

20. The multimedia content redirection method as claimed in claim 13, wherein the mobile code comprises at least one of a CODEC, a transport protocol (TP), a format parser, a transmission control protocol (TCP), and a user interface.

21. A computer readable medium having stored thereon instructions for executing a multimedia content redirection method for redirecting a multimedia content to a remote sink node in proximity and reproducing the multimedia content at the sink node, the instructions comprising:

a first set of instructions for reproducing multimedia content locally;

a second set of instructions for searching a proximity for a sink node;

a third set of instructions for determining whether it is possible to redirect the multimedia content to the sink node;

a fourth set of instructions for establishing a connection to the sink node;

a fifth set of instructions for dynamically extending functions of the sink node; and

a sixth set of instructions for redirecting the multimedia content to the sink node.

22. A computer readable medium having stored thereon instructions for executing a multimedia content redirection method for receiving and reproducing a redirected multimedia content from a source node which locally reproduces the multimedia content, the instructions comprising:

a first set of instructions for receiving a connection ready message from the source node;

a second set of instructions for determining whether a function extension is required to receive a redirected multimedia content;

a third set of instructions for requesting and receiving a mobile code from the source node;

a fourth set of instructions for dynamically extending functions based on the received mobile code when the function extension is required;

a fifth set of instructions for connecting a media player to the multimedia content; and

a sixth set of instructions for receiving the redirected multimedia content from the source node.
