Remote controller for controlling channel search velocity and/or volume level by touch-pad screen

A remote controller for controlling a channel search speed and/or volume level through a touch pad screen is provided to allow a user to quickly move to a desired volume level in proportion to a drag speed in controlling a volume level. A touch pad screen(401) senses a touch input and displays the first pointer for indicating the current channel of a TV. The first input unit(402) senses a drag direction and distance of the first pointer. A display controller(406) outputs a display control signal to display the first pointer on the touch pad screen(401), recognizes the drag direction and distance by the first input unit and outputs a channel search speed control signal. The first driving unit(404) outputs the first pointer on the touch pad screen(401) according to the display control signal. A receiving unit(409) receives the first pointer signal from the TV and outputs it. A controller(407) outputs a transmission control signal for controlling so as to transmit the channel search speed control signal to the TV, and receives the first pointer signal from the receiving part(409) and outputs it to the display controller(406). A transmission unit(408) transmits the channel search control signal to the TV according to the transmission control signal.
