A/V system available for integrated control and method of controlling the same
First Claim
1. A method for controlling a plurality of devices including a master device having AV terminals and slave devices connected to the master device through a communication control line, with the use of a single remote control, comprising:
- (a) detecting the slave devices, and allocating a device ID to each of the respective detected slave devices;
(b) identifying to which slave device of the detected slave devices each AV terminal is connected, by controlling the detected slave devices to be powered on or off through the communication control line with the use of the device IDs;
(c) receiving a predetermined key code from a user'"'"'s remote control; and
(d) determining which device among the master device and the detected slave devices to control and determining an operation of the determined device, by referring to an item of a mapping table corresponding to the key code, and controlling an operation of the determined device through the communication control line with the use of the device ID of the determined device.

4. A master device for identifying a slave device connected thereto through a communication control line, comprising:
-
a control signal transceiver transmitting a packet including various control commands to the slave device and receiving response packets to the control commands; a control signal generating unit generating the control command in the form of a digital signal in compliance with a predetermined protocol; and a device ID generating unit allocating a device ID to the slave device, wherein, when the communication control line is in a series communication mode, the control signal generating unit generates a control signal to disconnect terminals connected between slave devices and a control signal to connect the connected terminals.

5. A slave device connected to a master device through a communication control line, which is identified by the master device, comprising:
-
a control signal transceiver receiving a packet including various control commands from the master device and transmitting response packets to the control commands; a communication control line through which the master device and the slave device are connected and through which the packets move; a memory storing therein the device ID received from the master device; a buffer which connects communication between the slave device and another slave device; and a buffer control unit disconnecting or connecting the buffer according to the control signal received from the master device, when the communication control line is in a series communication mode.
