发明名称 External control of parental content controls in institutional television receivers
摘要 An institutional television receiver includes parental content controls for selectively blocking television signals based upon encoded ratings therein. The television receiver is coupled to a control center via a communications path. User preferences regarding the parental content controls are set, enabled, and disabled from the control center. User commands are supplied from the television receiver to the control center which, in turn, sends appropriate commands back to the receiver for controlling it.
