Church and Dosch to Talk
"Studios and Surround" at NAB 2005
---
21 March 2005,
Cleveland Ohio, USA
Surround broadcasting is clearly the hot topic at audio, consumer
electronics, and computer shops throughout the world. Visit any of these
locations and you’ll see plenty of surround audio set-ups that can only
lead the man-on-the-street to concur that stereo is nearly obsolete.
However, radio broadcasting has been absent from participation in the
advance of surround listening.
Since radio’s business is uniquely dependent upon creating a satisfying
aural experience for the listener, it’s time for radio to take the next
logical step: developing “Studio Structures for Surround Broadcasting.”
Telos Systems’ founder and CEO, Steve Church, along with Mike “Catfish”
Dosch, president of Telos’ Axia Audio division, will present their white
paper on this topic at the 2005 NAB Convention in Las Vegas on April
18th at 1:30 P.M.
The introduction of iBiquity’s HD Radio™ in the USA and the developing DAB
technology in Europe offers the radio industry an opportunity to provide
consumers with the quality digital surround they have already come to
expect from movie theaters, DVD film, TV broadcasts, surround music
disks, computer audio and portable players. Steve Church points out that
today’s immersive, high-quality surround sound is far different from the
“quad” formats of the Seventies: “Surround is being delivered to
consumers digitally in the so-called 5.1 format, providing six discrete
digital channels. Our modern systems offer a tremendous jump in quality
over the early quadraphonic attempts to woo consumers.”
In their presentation, Church and Dosch will discuss the real-world
practicality of upgrading a radio broadcast facility to surround. As
Dosch tells it, broadcasters will “need to upgrade studio facilities to
surround. Specifically, we need to store, network, and mix in the 2 +
5.1 format. We’ll examine what costs are associated with a surround
upgrade, and how computer networking is a more capable, lower-cost
substitute for obsolete analog and 20-year-old first-generation digital
technologies.” Furthermore, Dosch adds, broadcasters may be surprised to
learn that the “networked” console approach to upgrading for surround is
much less expensive than conventional (router-based) systems for stereo
studios.
“Studio Structures for Surround Broadcasting” will give attendees the
specifics of what will be needed to build a modern 2 + 5.1 plant, with a
careful eye towards costs and covering the routing and distribution
infrastructure. The presentation will also touch on PC-based delivery
systems, mixing console, surround encoding, dynamics processing, STLs
and transmission.
