ABSTRACT:
A two-way broadcasting system and a receiving system which can be realized at a low cost and is not required to newly connect the connecting cables and extended wiring layout. A multiplexed broadcast signal is transmitted from the broadcasting side under the condition that the two-way broadcast program information can be separated from the principal audio signal of the broadcast program and the two-way broadcast program information can be reproduced as the audible sound in the receiving side. In the receiving side, such broadcast signal is received and the reproduced voice signal including the two-way broadcast program information is reproduced from a loud speaker system. The two-way broadcast program information is extracted from the collected voice signal and is then decoded in a decoding means. Using this decoded information, the response information to the two-way broadcast program can be transmitted to the predetermined response sending destination through the communication line.
