Method for delivering user input, and device using same

1. A method of delivering a user input received from a Human Interface Device (HID) to a source device by a sink device, the method comprising:

receiving, by the sink device, the user input from the HID, wherein the user input is generated by the HID;

generating, by the sink device, HID user input information including a first field that represents a type of the HID, a second field that represents an interface type of the HID, and a third field that includes the user input received from the HID; and

transmitting, by the sink device, the generated HID user input information to the source device,

wherein the user input generated by the HID is delivered to the source device through a user input back channel which is established between the sink device and the source device, and

wherein the sink device receives multimedia contents from the source device, and the sink device renders the received multimedia contents.

2. The method according to claim 1 , wherein the first field has a value corresponding to one of a keyboard, a mouse, a touch device, a joystick, and a motion device according to the type of the HID.

3. The method according to claim 1 , wherein the second field has a value corresponding one of infrared, USB, Bluetooth, ZigBee, and Wi-Fi according to the interface type of the HID.

4. The method according to claim 1 , wherein the third field comprises the user input in the same format as the user input received from the HID.

5. The method according to claim 4 , wherein the user input in the third field has an HID format defined by a USB standard.

6. The method according to claim 1 , wherein the generated HID user input information further comprises information on a usage of the HID user input information.

7. The method according to claim 6 , wherein the information on the usage represents whether the HID user input information comprises data or control information.

8. The method according to claim 1 , wherein the generated HID user input information is delivered to the source device via TCP/IP.

9. A sink device delivering a user input received from a Human Interface Device (HID) to a source device, the sink device comprising:

a user interface unit that receives the user input from the HID, wherein the user input is generated by the HID;

a control unit that generates HID user input information including a first field that represents a type of the HID, a second field that represents an interface type of the HID, and a third field that includes the user input received from the HID; and

a wireless transmitting/receiving unit that transmits the generated HID user input information to the source device, and

wherein the user input generated by the HID is delivered to the source device through a user input back channel which is established between the sink device and the source device, and

wherein the sink device receives multimedia contents from the source device, and the sink device renders the received multimedia contents.

10. The device according to claim 9 , wherein the first field has a value corresponding to one of a keyboard, a mouse, a touch device, a joystick, and a motion device according to the type of the HID.

11. The device according to claim 9 , wherein the second field has a value corresponding one of infrared, USB, Bluetooth, ZigBee, and Wi-Fi according to the interface type of the HID.

12. The device according to claim 9 , wherein the third field comprises the user input in the same format as the user input received from the HID.

13. The device according to claim 9 , wherein the generated HID user input information further comprises information on a usage of the HID user input information.

14. The device according to claim 9 , wherein the wireless transmitting/receiving unit packetizes the generated HID user input information and transmits the packetized generated HID user input information to the source device via TCP/IP.
