    (54) Method of transmitting data in RDS broadcasting


    (57) A data transmitting method in the RDS broadcasting in which, when a data group of a group unit comprising four blocks is inserted into a radio broadcasting wave and transmitted, data is effectively inserted into each block and inserted data can be effectively used upon reception. According to the first feature, high order four digits and low order four digits of the PS data of at most eight digits are respectively transmitted as the data in the third and fourth blocks in each group, so that the broadcasting station name can be promptly displayed. As another feature, the PI code of the station itself is transmitted as the PI code in the first block in one group and, if a station which broadcasts a program different from the program of the station itself for only a predetermined time zone exists in the same network stations, the PI code of such a station is transmitted as the PI code in the third block.
