An Integrated Receiver/Decoder(IRD) is a reception device for Pay-TV, comparable to a set-top box
. The integrated receiver/decoder can receive encrypted TV signals, decrypt them and decode them for playback on the TV screen. Data streams from data -reduced digital TV are converted into a video signal
by the IRD box. The differences to the set-top box are not clear, but the IRD does not have a connection to the telephone network and is therefore not suitable for interactive distribution services.
