A video device controller (101) and method for generating a key code enable key code generation by a single instance of manipulation of the controller by a user The video device controller (101) includes a touch pad (110) having a predetermined touch pattern; a coordinate recognition unit (120) for recognizing coordinate values corresponding to a touch trajectory executed with respect to the touch pad (110); a key signal input unit (130), having a plurality of keys, for generating a key signal according to a user selection, the plurality of keys including at least one hotkey corresponding to a set of video device functions; a system controller (140) for generating, in response to a user operation of the hotkey, an OSD command signal for displaying an OSD keypad having a set of menu items corresponding to the video device functions, the OSD keypad being configured according to the predetermined touch pattern, for calculating values of at least one of a direction, speed, and distance of the touch trajectory using the recognized coordinate values, and for outputting a movement command signal based on the calculated values and the key signal, the movement command signal shifting an object among the OSD menu items displayed on the video device; and a key code generator (150) for respectively generating a key code corresponding to the OSD command signal and a key code corresponding to the movement command signal.
