Patent attributes
This communication system has a transmitter and a receiver for repeatedly transmitting a frame of steering signal having a plurality of channels. The transmitter stores an identification data of a control parameter of a specific operation object in a first empty channel within one frame and stores a characteristic data of the control parameter of the specific operation object in a second empty channel to transmit along with steering data of other channels. Since the identification data and the characteristic data are transmitted at the same time along with the control data, the control parameters can be changed during steering of the operation object. Since the characteristic data and the identification data are transmitted in the same frame as a pair, when at least the one frame is received, the setting of the control parameter can be changed.
