Disclosed is an information distribution system in which a receiving terminal installed in a mobile object can reliably receive high quality distribution information from the beginning. The information distribution system comprises data transmission units, each for transmitting a plurality of data signals including same distribution information using a plurality of different radio channels with sequentially delaying the transmission start time of the data signals; an auxiliary transmission unit for transmitting signals according to communication status of the data transmission units; a communication control unit for controlling the auxiliary transmission unit and the data transmission units; and detection means for detecting the velocity control information for the mobile object. A receiving terminal for receiving the data signals transmitted from the data transmission units is installed on the mobile object. The communication control unit selects a data transmission unit in a communication status according to the velocity control information out of the data transmission units, and controls the auxiliary transmission unit so as to notify the receiving terminal of the communication information corresponding thereto.
