Abstract

A method for converting a sink device and an apparatus for providing a content using the same are provided. The method for converting the sink device includes receiving a sink device conversion command from a first sink device, transmitting the content to a second sink device if a conversion approval of the sink device is received from the second sink device, and transmitting a control authority related to a content provision from the first sink device to the second sink device.

Claims

1. A display apparatus swapping method of a plurality of display apparatuses, each of which is capable of outputting a content transmitted from a source device, the method comprising:

the source receiving a recipient swapping command from a first display apparatus which receives contents provided from the source device, the recipient swapping command relating to swapping the first display apparatus as being a recipient of the contents to a predetermined second display apparatus from among the plurality of display apparatuses;

the source receiving a recipient swapping approval from the predetermined second display apparatus which is a swapping destination;

in response to the receiving the recipient swapping command, suspending the transmission of the content to the first display apparatus;

after the receiving operation that indicates swapping approval, transmitting the content to the predetermined second display apparatus; and

transmitting a control authority related to a content provision from the first display apparatus to the second display apparatus;

wherein the control authority is authority to control operation of the source device,

wherein the source device is controlled based on a command received from a display apparatus having the control authority, and

wherein the transmitting the content comprises separating the content into a video signal and an audio signal;

transmitting the video signal into a video device; and

transmitting the audio signal into an audio device.

2. The display apparatus swapping method according to claim 1, further comprising:

transmitting a turn-off request to the first display apparatus after the suspending operation, wherein the turn-off request relates to automatically turning off power to the display apparatus; and

transmitting a turn-on request to the second display apparatus after the receiving operation, wherein the turn-on request relates to automatically turning on power to the second display apparatus.

3. The display apparatus swapping method as claimed in claim 1, wherein the transmitting includes transmitting the content after the transmission is suspended in the suspending operation.

4. The display apparatus swapping method as claimed in claim 1, wherein the display apparatus recipient swapping command is a command which makes the source device swap from the first display apparatus to the second display apparatus and transmit the content to the second display apparatus.

5. A content-providing system which transmits data to a plurality of display apparatuses with each other which is capable of outputting a content comprising:

a communication interface, implemented by a transceiver, which enables communication between said content providing apparatus and at least a first display apparatus and a second display apparatus, each of which is capable of outputting a content; and

a control unit, implemented by a processor, which receives a recipient swapping command from the first display apparatus which receives contents provided from the source device through the communication interface, receives a recipient swapping approval from the predetermined second display apparatus which is a swapping destination, suspends content transmission to the first display apparatus in response to receiving the display apparatus recipient swapping command from the first display apparatus, transmits the content to the predetermined second display apparatus through the communication interface in response to receiving the recipient swapping approval from the second display apparatus, and transfers a control authority related to a content provision from the first display apparatus to the second display apparatus,

wherein the recipient swapping command relates to swapping the first display apparatus as being a recipient of the contents to the predetermined second display apparatus,

wherein the control authority is authority to control operation of the content-providing apparatus,

wherein the content-providing apparatus is controlled based on a command received from a display apparatus having the control authority, and

wherein the control unit transmits a video signal separated from the content to a video device through the communication interface and transmits an audio signal to an audio device through the communication interface.

6. The content-providing apparatus as claimed in claim 5, wherein the control unit transmits a turn-off request to the first display apparatus through the communication interface after suspending the content transmission to the first display apparatus, wherein the turn-off request relates to automatically turning off power to the first display apparatus, and

wherein the control unit transmits a turn-on request to the second display apparatus through the communication interface if the display apparatus recipient swapping command is received from the first display apparatus, wherein the turn-on request relates to automatically turning on power to the second display apparatus.

7. The content-providing apparatus as claimed in claim 5, wherein the control unit transmits the content to the second display apparatus through the communication interface, after the transmission was suspended.

8. The content-providing apparatus as claimed in claim 5, wherein the display apparatus recipient swapping command is a command which makes the content-providing apparatus swap from the first display apparatus to the second display apparatus and transmit the content to the second display apparatus.

9. A controlling method of a content-providing apparatus comprising:

receiving a recipient swapping approval from a display apparatus which is a swapping destination;

suspending transmission of content to an external apparatus in response to a received recipient swapping command which relates to swapping a recipient of the content;

after the receiving the recipient swapping approval,

transmitting the content to the display apparatus; and

transmitting a control authority related to a content provision from the external apparatus to the display apparatus,

wherein the control authority is authority to control operation of the content-providing apparatus,

wherein the content-providing apparatus is controlled based on a command received from a display apparatus having the control authority, and

wherein the transmitting the content comprises separating the content into a video signal and an audio signal;

transmitting the video signal into a video device; and

transmitting the audio signal into an audio device.
