Abstract: An information transmission apparatus 2 makes transmission objective data redundant using a predetermined method, divides the redundant data into N (N?2) data elements, the transmission objective data being reproducible on the basis of any arbitrary combination of m (m<N) or more data elements, and sequentially transmits short-range communication signals respectively including the N data elements obtained by the division. A terminal apparatus 3 which receives the data elements tries to reproduce the data using the received data elements, and transmits short-range communication signals including the received data elements.
