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.

Abstract: Provided are a voice command processing system and method. A voice command processing method includes constructing a plurality of databases, in which voice commands including an operation name are stored, receiving a voice command to separate the received voice command into an operation name and an object name, finding a database corresponding to the operation name within the plurality of databases, and finding the object name in the found database. According to the voice command processing system and method, time required to access a database corresponding to a voice command input by the user can be reduced.
