All DAB digital radio receivers come with a small screen. This screen serves two purposes: first it lets you scroll through a list of stations to find the one you want, and then, once you’ve settled on a station, it displays a line of scrolling text generated by that radio station.
Most stations already use scrolling text to broadcast their name and music format. Some also identify the track and artist you’re listening to, tell you what songs are coming up next, deliver news headlines, sports results, contact web addresses and telephone numbers.
