First Claim
1. An apparatus for controlling selective viewing of a broadcast program for a video appliance, comprising:
- a receiving section for receiving a broadcast program signal through a receiving antenna;
a control signal receiving section for receiving a broadcast program selection control signal simultaniously transmitted with the modulation broadcast program signal, the control signal representing a viewing-restriction grade;
a determining section for determining viewing-restriction grades, the determining section including a coding section for qualifying a particular user to determine the viewing-restriction grades, and a viewing grade determining and releasing section for the user'"'"'s determining and releasing of the viewing-restriction grade;
a discriminating section for discriminating the viewing-restriction grade of the received broadcast program by comparing the viewing-restriction grade of the received broadcast program with that determined by the determining section;
a control section for determining whether admit the viewing of the received broadcast program in accordance with a discrimination result from the discriminating section;
a video/audio output section for outputting the video and audio signals of the broadcast program under the control of the control section;
wherein the program selection control signal received through the control signal receiving section is a multi-step signal which is composed of a plurality of control signals which are combined in accordance with the viewing-restriction grades of the broadcast program; and
wherein said pluralty of control signals forming said multi-step signal include first, second, and third control signals that are combined in hierarchical manner according to view restriction grade such that;
only said first signal is appended when viewing is permitted for a first restriction grade;
said first and second signals are appended when viewing is permitted for a second restriction grade; and
all of said first second, and third signals are appended when viewing is permitted for a third restriction grade.

Abstract
An apparatus and method for transmitting a broadcast program selection control signal, and controlling selective viewing of a broadcast program for a video appliance in which a viewing-restriction grade is set for a broadcast program and viewing of the broadcast program is restricted in accordance with the set viewing-restriction grade. According to the apparatus, the viewing-restriction grade of the broadcast program is determined and a control signal corresponding to the determined viewing-restriction grade is transmitted along with the broadcast program signal. In a television receiver, whether to admit the viewing of the received broadcast program is discriminated by comparing the viewing-restriction grade corresponding to the control signal with that predetermined by a user.
