Unless you work directly with iBiquity to design an Artist Experience
solution for your station, most details are left to a third-party vendor that
handles them for you.

For many that
might be good enough; but some users will want a true understanding of how the
technology and system works — and how to troubleshoot any issues.
“Data services delivered over HD Radio are an exciting and growing
development in the industry,” says Alan Jurison, senior operations engineer for
Clear Channel Media + Entertainment in Cincinnati and a Radio World
Artist Experience is a particularly visible application of that concept.
It uses some of the data bandwidth in the HD Radio stream to deliver graphical
images synchronized with the audio. This involves sending relevant images of
the current song on the air, such as album cover art.
Jurison will speak about technical details of AE on the Sunday morning
of the NAB Show. He plans to define the technology and promises a look at
current and planned receivers that support this technology.
Details of AE implementation are important to users to know about. For
example, he points to importer and exporter configurations.
“Having been part of the implementation of Artist Experience on nearly
400 stations at Clear Channel, a key takeaway for any group owner considering
this technology is to standardize software versions, configuration settings and,
if possible, importer/exporter hardware, to enable rapid mass deployment and
support,” he said.
a new importer software program written by iBiquity that schedules the images;
it is called Multiport Synchronous/Asynchronous Client, or MSAC. Jurison will
discuss the types of messages that a station’s Artist Experience solution needs
to send to the MSAC.
messages allow MSAC to schedule image transfers into the future, and Sync
messages tell MSAC that the song has just started to schedule an image resend
shortly after the song has started.”
Also on tap
are timing requirements to get the images transferred in time before the song
starts, to ensure the image is synchronized with the audio and provide the best
experience to listeners. Further topics include how receivers obtain and store
the image before display, and some of the caching methodologies used by various
manufacturers. His presentation also notes third-party Artist Experience
providers that can assist stations in implementing it.
OEM (factory-installed) HD Radios with Artist Experience will be very common in
a few years,” he said. “It’s important that your company creates a strategy to
implement this technology.”
