PROBLEM TO BE SOLVED: To relieve a load of a public line by transmitting not only an interrogation image but also a program to discriminate correctness/error with respect to an answer of a viewer and to display the result from a broadcast center to each home terminal and allowing each terminal to execute the program so as to eliminate the need of a procedure to send the answer from each terminal to the broadcast center. SOLUTION: A multiplexer section 202 of a transmitter 101 multiplexes navigation information 200 and video audio data 201, a Carousel repeater transmission section 203 transmits the multiplexed data to a terminal 104a as broadcast data 105 adopting the Carousel system, a demultiplexer section 206 demultiplexes the data into video audio data 201 and information 200, which is stored in a storage section 207. On the other hand, a video audio reproduction section 208 decodes the data 201 and a television receiver 211 displays the decoded data. In parallel with the reproduction of the video image and the music, a byte code execution section 209 conducts processing of presentation of questionnaires. The execution section 209 accepts selection of an image object through the control of a remote commander 210 on the other hand and completes entry of an answer. Furthermore, the execution section 109 displays correctness / wrong answer on the television receiver 211. |
