Process for automatic censoring of audiovisual programmes enabling the user responsible for a set to eliminate programmes deemed undesirable through considerations such as their origin, nature or content, consisting on the one hand in marking the programmes with the aid of an electronic programme-code inseparable from the programme itself, and on the other hand in equipping the receiving set with the following means: - a means of creating a confidential access code reserved for the responsible user, - a means for selecting permissible limits on the receiving set, which limits are defined with the aid of a receiver-code formulated by the user employing the confidential code, - an automatic means of comparing the programme-code received and the receiver-code, - an automatic means of suppressing the programmes which exceed the limits fixed by the receiver-code, - a means of temporary dispensation allowing momentary cancellation of the censoring, - and an optional means for the remote logging of the receiver-code by an authorised agency, for the purposes of statistical studies of general interest.
