Advertisements Programme Delivery Control is a system used in Europe where a signal is transmitted (once a second) as part of the digital broadcast. It has two main purposes. It can tell you when a program starts and stops so that it is easier to record accurately if the start and stop time of a show varies from schedule. The second purpose is to allow the network to send scrambled signal to confuse the DVR so that the program can't be recorded. The latter purpose can be defeated by simply setting the recorder for a fixed start and stop time. Any chance that TV (cable or OTA) in the USA will adopt a similar standard?
