Why do live events transmit faster to my digital radio than my TV?

Asked by: Mary Brooks, Totnes

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, or cache, 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.
