A process and network able to restrict a video appliance equipped with either a single tuner or with multiple tuners, from receiving and subsequently displaying video image signals represented by an accompanying broadcast discretionary control data to include a high level of objectional content. A multi-tuner television receiving appliance may be constructed with at least two tuners receiving a program; a viewing restricting portion detecting a discretionary control data of the program received through one of the tuners and blocking AGC signals of the tuner receiving the program when the discretionary control data is greater than a discretionary threshold; a control portion blocking AFT signals of the other tuners when the viewing of the program received the receiving tuner is restricted.
