Abstract An information signal (INF) which is transmitted in coded form (CINF) from a signal source (RC) to a signal receiver (4, 5) is decoded at the receiver and at the same time marked (MINF) by the introduction of an identification infor- mation (ID) which is characteristic of the receiver or its possessor. The signal from a video disc (RC) carrying a coded programme is decoded and marked before it is supplied to a television set (6). Via said identification informa- tion a so called pirate copy is directly traceable to its originator. Thereby a protection against such copying is obtained. A device for the playback of a video disc of this type comprises a decoding and modification unit to which the necessary decoding information and identification information may be supplied from a personal data carrier (ID). (Fig.1).
