Abstract
A system for controlling reception or recording of television broadcasts according to censorship classifications. One or more persons monitoring broadcasts nominate a classification and cause an appropriate signal to be generated and transmitted to viewers' homes by means of a radio transmission network also used for transmission of other data signals, such as a pocket paging system. Means are provided to ensure that classification signals are transmitted with priority over paging signals or other non-time-critical data.
