PURPOSE: An automatic remote controller sensing controlling method through a gyro sensor is provided to reduce location variation width of a pointer according to a remote controller operation in case the pointer escapes from an effective area on an IPTV screen. CONSTITUTION: A controlling unit transmits a second pulse signal(S120). The second pulse signal is a signal for informing that a remote controller moves to be operated at an initial point. A signal processing unit generates a control signal for commanding the location change of a pointer according to the second pulse signal(S130). The controlling unit determines whether the pointer is located in an effective area according to the control signal(S140). The controlling unit reduces the location variation width of the pointer(S180). |
