PDC meaning in Networking ?

Programme delivery control (PDC) is specified by the standard ETS 300 231 (ETSI EN 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 (also known as Enhanced Teletext Packet 8/30 Format 2) 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 also known as format 2. Effectively, the two systems do the same thing and most modern VCRs and stand-alone DVD recorders work with both signals.

The VPS system was invented by Mit-hat Sheqerolli in April 1983 under the name of "Run-time controller for the recordings of television programmes by means of a videorecorder".

In digital TV (see Freeview+), the feature Accurate Recording (AR) that was based on the PDC specification for analogue recording devices is now used for a DVB-SI event based scheduling system. This was due to the BBC discontinuing the Ceefax service.
