ABSTRACT:
A method and apparatus for securely restricting the viewing of television programs. When a television program has been received along with rating data associated with a rating of the television program; length data associated with a length of the program, a microcomputer determines whether the rating data are higher than a predetermined viewing restricting level. If the rating data have been found higher, a muting circuit mutes the television program until it ends with reference to the television program length data, and the program corresponding to the rating data is outputted from a tuner.
