In DAB, the transmission equipment samples the signal in chunks, so it takes a few fractions of a second to convert it into binary. When the signal arrives at your DAB receiver, it streams the data into a buffer, which then passes it to the digital-analogue converter. The lag is the result of these combined sampling delays.
