A method for transmitting teletext signals from a transmitter to a plurality of receivers wherein a plurality of successive and numbered teletext pages are transmitted currently. In addition to the teletext pages determined for all the receivers, it is possible to transmit a plurality of pages which are determined to be received only by one or more selected receivers. Each of these receivers has been allocated a digital address and comprises a store for storing teletext pages. Control signals are transmitted to the selected receiver or receivers on a given teletext page, said control signals comprising addresses of the selected receiver or receivers as well as information on the point or points of time at which teletext pages determined for said receivers will subsequently be transmitted. Then the pages determined for said receivers are transmitted, and said pages are received by said receivers and stored in the store of each receiver. |
