Реферат: The invention provides an information network system which includes a broadcasting center, a broadcasting receiving user terminal, and a data base center connected to the user terminal by a network. The information network system offers bidirectional communication between the user terminal and the data base center and between the data base center and a broadcasting station for a user to enjoy bidirectional communication in regard to broadcasting. The broadcasting center includes a guiding instructions addition section for multiplexing guiding instructions regarding how to access the data base that includes a URL (Universal Resource Locator)for the data base center, into the broadcasting signal for the program to be transmitted. The user terminal also includes a guiding instructions extraction section which extracts the guiding instructions including the URL from the broadcasting signal and a network communication section which accesses the data base and receives a response from the data base center.
