Digital audio or video is transmitted as a series of binary bits. Like a dam holding back water in a stream, broadcast equipment stores up a backlog of data. Then, if there are dropouts in transmission, there’s a sufficient supply to maintain the signal without interruption. Some services buffer more than others, explaining the discrepancy between digital radio and digital TV.
