Programme Delivery Control
Programme Delivery Control (PDC) is a standard (ETS 300 231) to control video recorders using hidden codes in the teletext service. The PDC data indicates to the recorder when a show or program starts.
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+), Accurate Recording is the equivalent feature.
