Abstract (en)
[origin: WO9836570A1] An arrangement for the control of viewing of a television programme in which a classification code is transmitted with the video signal, for example in an extension packet of a teletext signal, includes a decoder (23) which detects the received codes and passes them to a microcontroller (27). An authorised user is able to enter codes of permitted programme classifications by means of a remote control unit (28). Codes representing these permitted classifications are stored in a non-volatile memory (29). The received and permitted codes are compared in the microcontroller (27) which inhibits the video (25) and/or audio (32) circuits if the received codes are not permitted codes. An indication means (38) is provided which indicates whether classification codes are being received and detected.
