发明名称 Viewing limit apparatus, viewing limit system, and viewing limit program
摘要 First rating information, together with a television broadcasting signal, is transmitted, and second rating information, together with electronic program guide information, is transmitted. A controller extracts the first rating information from video data decoded by a video decoder, and extracts the second rating information from EPG data decoded by an EPG processor. At the time of reserving a program, it is judged whether or not the program can be reserved by restricting viewing on the basis of the second rating information, and the result of the judgment is displayed on a program reservation setting guide.
