ABSTRACT:
A malfunction of interpreting one remote control operation as a plurality of remote control operations by mistake is prevented without impairing the responsiveness of a remote controller. A counter code which is updated each time a key of the remote controller is operated is added to a remote control signal. If an electronic device acquires the remote control signal from a control bus, the counter code contained in the remote control signal is checked to determine whether or not a remote control signal having the same count has already been acquired from the remote control light reception unit. If such a remote control signal has already been acquired, the remote control signal acquired subsequently is invalidated. Consequently, it is possible to prevent the inconvenience of a plurality of operations from being carried out due to validated remote control signals subsequently obtained through the control bus, without setting a certain time period in which all signals are considered to be the same.
