Believe it or not, there are still some U.S. broadcasters tinkering with the HD Radio protocol. One of the latest is Rick Sewell, the manager of engineering for Crawford Broadcasting’s stations in Chicago.
His latest project involved implementing HD’s “Artist Experience” feature – this is a fancy name for what is basically radio with pictures. AE allows HD-compatible stations to send album artwork and advertiser-images to digital radio receivers along with the audio programming; these are things that digital-native audio streaming services such as Pandora and Spotify mastered years ago.
There’s no coordinated drive from the broadcast industry to implement Artist Experience, and HD’s proprietor, Xperi Corporation, isn’t actively marketing the technology to broadcasters much anymore. Apparently, one of Sewell’s colleagues was down in Atlanta and got a rental-car with an HD-compatible receiver. This guy stumbled across a station that had implemented AE and thought, “we should do this too.”
Thus began Sewell’s saga. He’d initially hoped that he would have time to explore the HD system in more detail, but station management had already started pitching the Artist Experience opportunity to advertisters. The first step was to make sure that the HD airchain of the station on which AE would be deployed was totally up to date. That got figured out after Sewell got over his own “ignorance as well as some misinformation along the way.”
