1. (amended) A viewing restricting apparatus comprising:
- a receiver that receives a television broadcasting signal, together with first rating information for restricting viewing, and receives electronic program guide information, together with second rating information for restricting viewing;
a program output unit that outputs a video or an audio of a program on the basis of the television broadcasting signal received by said receiver;
an information holding unit that holds the electronic program guide information received by said receiver; and
a controller, wherein said controller has a first information extracting function for extracting the first rating information from the television broadcasting signal received by said receiver, a first output restricting function for restricting the output of the program by said program output unit on the basis of the first rating information extracted by said first information extracting function, a second information extracting function for extracting the second rating information from the electronic program guide information held by said information holding unit, and a second output restricting function for restricting the output of the program from said program output unit on the basis of the second rating information extracted by said second information extracting function.

Abstract
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.

19. A viewing restricting system comprising:
-
a transmitting device that transmits a television broadcasting signal, together with first rating information for restricting viewing, and transmits electronic program guide information, together with second rating information for restricting viewing; and
a receiving device that receives the television broadcasting signal transmitted by said transmitting device, said receiving device comprising a receiver that receives the television broadcasting signal transmitted by said transmitting device, together with the first rating information, and receives the electronic program guide information transmitted by said transmitting device, together with the second rating information, a program output unit that outputs a video or an audio of a program on the basis of the television broadcasting signal received by said receiver, an information holding unit that holds the electronic program guide information received by said receiver, and a controller that extracts the second rating information from the electronic program guide information held by said information holding unit, and restricts the output of the program from said program output unit on the basis of the extracted second rating information.

21. A viewing restricting program, which is readable by a computer, for restricting viewing in a television receiver comprising a receiver that receives a television broadcasting signal, together with first rating information for restricting viewing, and receives electronic program guide information, together with second rating information for restricting viewing, and a program output unit that outputs a video or an audio of a program on the basis of the television broadcasting signal received by said receiver, for causing said computer to perform:
-
processing for holding said received electronic program guide information;
processing for extracting the second rating information from said held electronic program guide information; and
processing for restricting the output of the program from said program output unit on the basis of said extracted second rating information.
