Abstract: When advertising information is included in a received broadcasting wave, viewer attributes which have previously been registered in an IC card is collated with a target ID added to the advertising information, and the advertising information (icon) in which both of them coincide is selected and displayed (S3, S4). When there is a requesting operation of detailed information, the detailed information is obtained by link information. The detailed information can be obtained from the broadcasting wave (S11, S12) or can be obtained from a homepage via the internet (S17, S18). The detailed information is displayed in place of the picture plane of a program. When a viewer requires to finish the display, the display of the detailed information is finished (S14, S20). When the detailed information is displayed, the presence of the request for the detailed information is recorded as a history.

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.

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.

Abstract: A plurality of classification items each including a plurality of detailed items for recognizing broadcasting programs per se and program elements included in each of the broadcasting programs are provided wherein the contents of each of the broadcasting programs are represented by the classification items and the detailed items that are respectively represented by the identification data are used to form scheduled program information. The scheduled program information is broadcast together with the corresponding table data for the identification data and the data for character display of the classification items and the detailed items corresponding to the identification data. Program schedules for various kinds of broadcasting programs can be broadcast with a reduced amount of data.

Abstract: In a microcomputer system with an asynchronous working central processing unit (CPU) and a cathode ray tube (CRT) display, a memory access control apparatus includes a memory, particularly a video RAM, a CRT controller connected to the CRT for accessing the memory, a system clock for generating system clock pulses which are supplied to the CPU, a multiplexing clock for generating multiplexing clock signals based on the system clock and having a frequency which is one-half the frequency of the system clock pulses, and a multiplexer connected to the CPU and the CRT controller through which the CPU and the CRT controller selectively access the memory in a time sharing manner according to the multiplexing clock signals.
