A signal transmitting/receiving system and method, signal transmitting apparatus and method, signal processing apparatus and method, recording medium, and program are provided. A signal transmitting/receiving system includes a transmitter configured to transmit signals; and a receiver configured to receive the signals transmitted from the transmitter. The transmitter transmits signals using a first signal having an edge at a position that is 1/n from the beginning of a unit segment and a second signal having an edge at a position of (n−1)/n from the beginning of a unit segment, where n is an integer greater than or equal to three, one of the first signal and the second signal representing logic “0” and the other representing logic “1”. The receiver determines a signal type based on a length of an edge interval of either rising edges or falling edges of the signals received.
