Abstract: 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. The method includes detecting the slave devices, and allocating a device ID to each of the slave devices, identifying to which slave device 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 ID, receiving a predetermined key code from a user's remote control, and determining which device among the master device and the slave devices to control and determining an operation of the device, by referring to an item of mapping table corresponding to the key code, and controlling operation of the device through the communication control line with the use of the device ID.

Abstract: A method and device for controlling slave devices with a master device. The device performs specific functions to control operations of slave devices with a master device, and includes a user input receiving unit that receives an input from a user, a memory unit that stores command sets, each command set corresponding to a series of operation controls of the master device or one of the slave devices, and a control unit that generates operation control signals of the master device or one of the slave devices when an operation control command set is selected, the operation control signals corresponding to the selected operation control command set.

Abstract: A device for controlling in an integrated manner multiple slave devices includes a key input unit that receives a key input by a user, a state determination unit that checks state information of the slave devices, and a control unit that interprets the input key based on the state information of the slave devices and controls a concerned slave device of the slave devices. A method for controlling multiple slave devices includes receiving a key input by the user, checking state information of the slave devices existing on the network, and controlling the concerned slave device by interpreting the input key based on the state information of the slave devices.

Abstract: A method and apparatus for effectively performing optimal connection configuration by recognizing the connection status between a video device and external peripheral devices. The method for identifying predetermined peripheral devices connected to a video device over serial communication control lines, includes, transmitting a command to establish connection of a current peripheral device having no given device ID to its upper peripheral device among the predetermined peripheral devices, and transmitting a command to disconnect a connection to its lower peripheral device; requesting unique device identification information to the predetermined peripheral devices; receiving a response to the request from the current peripheral device; and giving a device ID to the current peripheral device.
