Unformatted text preview: Why HD Radio is Important to You Think of it: one station on one frequency delivering many program feeds. It’s hap- pening now. The first real world, commercial multicasts—multiple digital channel transmissions—in early 2005 used Broadcast Electronics (BE) HD Radio equipment. By multicasting several program feeds, terrestrial radio stations in any given market can approach satellite program variety. A station could have music on one channel, news on another and sports programming on yet another. Or, run three complete- ly different music formats or multiple languages. Or, present variations of the same format targeted to different demographics. Simultaneously, “now playing” text and station branding for readout on the HD Radio receiver can be customized for each of the channels. A small investment in the additional HD Radio equipment required for multicasting can yield big growth in advertising revenue. Additionally, HD Radio lays the technological foundation for radio receivers to provide data to a car’s traffic navigational system or deliver other revenue-generating file transfers. In the world of terrestrial radio where localism is king and listeners want to hear about their community, all these applications allow the station to be the “hyper-local” source for local information on weather, news, traffic, community events and more. At the very least, HD Radio will make a big difference in the sound of AM and FM stations. All one has to do is listen to a digital radio tuned to an HD Radio broadcast. Absent are the hisses and pops typical of analog radio; it’s the closest you’ll get to CD quality on the broadcast dial. Did we mention that HD Radio fits into the same spectrum as current analog AM and FM broadcasts? Broadcasters do not have to eliminate their analog broadcasts to implement HD Radio, and listeners are not required to buy new receivers, or asked to choose between competing radio services on differing frequencies. HD Radio is broadcast together with today’s analog broadcasts within each station’s currently licensed broadcast spectrum. Comparatively inexpensive to implement, HD Radio will mature as a technology at the same rate as its consumer adoption.
