ABSTRACT:
A bidirectional broadcasting method and system allows, even when an existing telephone voting service is used to respond to a bidirectional broadcast, broadcasting wherein a plurality of questions are related to each other. A broadcasting station broadcasts questions, answer choices for a response to each question and responding destination telephone numbers for the individual answer choices, and successively broadcasts evaluation information for allowing receiver apparatus to perform evaluation of histories of responses to the questions and determine whether or not the responding persons of the individual receiver apparatus are response allowed persons. Each receiver apparatus stores the history of responses to the questions into a memory and, based on the evaluation data from the broadcasting station, evaluates the history of responses to the questions. Then, based on the selection data from the broadcasting station and a result of the evaluation, it determines whether or not a given person is allowed to respond to a later question. When it is determined that such person is not a response-allowed person, the receiver apparatus prevents origination of a call for a later response therefrom.
