A transmission and reception system including a transmitter for transmitting a signal including identification (security) information and function information, and a receiver for receiving and decoding the signal and for executing the operation defined by the function information upon verification of the identification information. The transmitter divides one or more of the identification information and the function information into two or more bit groups, and transmits these bit groups such that identification information bit groups are separated by function information and function information bit groups are separated by identification information. In one embodiment, the intermixed function and identification bit groups are transmitted without a time gap, and in another embodiment the function bit groups and the identification bit groups are arranged in groups containing one or more function information bit groups and one or more identification information bit groups, these groups then being transmitted with a time gap therebetween. The receiver includes information necessary for recombining the identification information and the function information for performing verification of the identification information and execution of the operation defined by the function information. In a further embodiment the identification information includes both fixed and variable codes, the variable code being changed after each transmission.
A signal generation method for a system including a transmitter and a receiver in which a transmission signal is transmitted from the transmitter to the receiver, the transmission signal including a transmitted-signal group comprising identification information and command information, the identification information including a first plurality of bits and the command information including a second plurality of bits, the transmission signal being received, decoded and processed by the receiver, the signal generation method comprising the steps of:
