Programme Delivery Control
Programme Delivery Control (PDC) is specified by the standard ETS 300 231, published by the European Telecommunications Standards Institute (ETSI). This specifies the signals sent as hidden codes in the teletext service, indicating when transmission of a programme starts and finishes.
PDC is often used together with StarText, enabling the user to select a programme to record using specially coded teletext programme listings. The combination of features is often called PDC/StarText
In Germany and some other European countries, the older standard Video Programming System (VPS) is in use. Effectively, the two systems do the same thing and most modern VCRs and stand-alone DVD recorders work with both signals.
In digital TV (see Freeview+), the feature Accurate Recording is based on the PDC specification.
