PROBLEM TO BE SOLVED: To enable a receiver to arbitrarily and simultaneously receive a plurality of digital audio broadcasting programs received and demodulated through a receiving section at a luraility of terminals by applying multipath measures on the programs and arbitrarily selecting the programs at the terminals. SOLUTION: A deinterleaving/error correcting section 24 makes a plurality of audio pograms which are collectively broadcast by digitizing a plurality of quadrature carriers always receivable by performing deinterleaving for frequency and time on a symbol string superimposed upon each carrier separated by means of the QPSK demodulator 23 of quadratwe frequency dividing and multiplexing receiving section 2. At a terminal section 4 having a plurality of terminals, a selector/display 3 selects the data of the category desired by a user from the data sent through a bus line 5 and terminals 41 to 44 control the sending timing of a broadcasting program for sending base-band data stored in a buffer memory to an MPEG audio decoder. |
