ABSTRACT:
A two-way broadcasting system and method by which the amount of accesses from the reception side can be controlled with certainty by the broadcasting side and a receiving apparatus for use with the method wherein, information of a reply to a question from a broadcasting side is transmitted from a reception side to the broadcasting side by way of a telephone line. Each receiving apparatus on the reception side has individual identification information, and the broadcasting side broadcasts information regarding a reply destination and telephone call origination limiting information for limiting transmission of the information of a reply in a multiplexed condition with a broadcasting signal from the broadcasting side. On the reception side, transmission of the information of a reply to the reply destination is inhibited when the identification information peculiar to a receiving apparatus on the reception side satisfies a condition provided by the telephone call origination limiting information for inhibiting a telephone call origination of a reply to the reply destination.
