Abstract

A method and a digital device for controlling a connection between a plurality of nodes through an interface are discussed. The method according to an embodiment includes receiving control information including identification information of a destination node and a connection command. The destination node is connected with the interface based on the connection command, and the destination node maintains a connection state until a disconnection command is detected. The method further includes transmitting, according to the control information, response information including identification information of a source node.

Claims

1. A method for controlling a connection between a plurality of nodes through an interface, the method comprising:

receiving control information including identification information of a destination node and a connection command, wherein the destination node is connected with the interface based on the connection command, and the destination node maintains a connection state until a disconnection command is detected,

wherein during the connection state, a physical connection between the plurality of nodes is maintained to receive the disconnection command through the interface, and

wherein if the disconnection command is detected, the destination node is released from the interface and the physical connection between the plurality of nodes is maintained to receive a new connection command through the interface; and

transmitting, according to the control information, response information including identification information of a source node.

2. The method of claim 1, wherein the identification information is a unique physical node identifier.

3. The method of claim 1, wherein the control information and the response information are preformatted.

4. The method of claim 1, wherein the destination node is at least one of a digital versatile disc (DVD) player, a digital television (DTV), or a set-top box (STB).

5. A digital device for controlling a connection between a plurality of nodes through an interface, the digital device comprising:

a receiver configured to receive control information including identification information of a destination node and a connection command, wherein the destination node is connected with the interface based on the connection command, and the destination node maintains a connection state until a disconnection command is detected,

wherein during the connection state, a physical connection between the plurality of nodes is maintained to receive the disconnection command through the interface, and wherein if the disconnection command is detected, the destination node is released from the interface and the physical connection between the plurality of nodes is maintained to receive a new connection command through the interface; and

a transmitter configured to transmit, according to the control information, response information including identification information of a source node.

6. The digital device of claim 5, wherein the identification information is a unique physical node identifier.

7. The digital device of claim 5, wherein the control information and the response information are preformatted.

8. The digital device of claim 5, wherein the destination node is at least one of a digital versatile disc (DVD) player, a digital television (DTV), or a set-top box (STB).
