Harris Corporation’s New SynchroCast3 Enables Radio Broadcasters to Create Single-Frequency Networks over IP Links
New Simulcasting Product Expands Broadcast Coverage Area and Listener Base
CINCINNATI.-(Booth #N2502, LVCC) — Harris Corporation (NYSE: HRS), an international communications and information technology company, will introduce SynchroCast3™ and IP simulcasting capability with its Intraplex® NetXpress™ IP multiplexer at the 2008 National Association of Broadcasters (NAB) convention being held April 14-17, 2008, in Las Vegas.
With SynchoCast3™ IP simulcasting, Intraplex® NetXpress™ customers now have the ability to use Harris Corporation’s proven simulcast technology to create Single-Frequency Networks (SFN) over IP transport networks, which allows them to expand their coverage area and listener base.
SynchroCast3™ features of upgraded hardware modules plus brand new software that interfaces SynchroCast3 technology with the Intraplex® NetXpress™ audio over Internet Protocol (IP) networking platform. Until now, SynchroCast3™ was only available for Intraplex® multiplexers, which use dedicated, wired T1/E1 telco circuits.
“SynchroCast3™ IP is an innovative product that makes it possible to construct SFN simulcast networks over IP links — a capability that is new to the radio broadcast market,” said Steve Edie, product manager for the Intraplex® product line for Harris Broadcast Communications. “SynchroCast3™ IP adds the precision of digital GPS timing to increase coverage areas — especially in geographical regions with difficult terrains. It also reduces interference that commonly results when different transmitters operate simultaneously on a single radio transmitter network.”
Intraplex® NetXpress™ audio over IP platform enables customers to send multiple audio programs in multiple formats (including HD Radio™), data, and PBX telephone communications over a single IP connection. IP transport solutions offer greater cost- and bandwidth-efficiency than expensive, fixed bandwidth T1, microwave, or fiber T1/E1 circuits.
At NAB2008, Harris also will demonstrate network interface module redundancy on its NetXpress™ IP multiplexer platform. When combined with existing power supply redundancy features, network module redundancy virtually eliminates the potential for system-level hardware failure.
“The greater bandwidth and cost-efficiency of IP networks promotes the transmission of more audio channels over IP, with one device feeding the same signal to multiple devices,” said Edie. “So, if that originating device should fail, large parts of the network would fail.”
Since the NetXpress™ NIM-1 control module and the MIU-201 interface module are single points of failure on the IP network, module redundancy allows the user to add a second NIM-1 and MIU-201 to the NetXpress™ chassis. Edie added, “Should either of the primary modules fail, the back-up unit activates and keeps the system online and on the air.”
Intraplex® NetXpress™ is among the wide range of Harris solutions that optimize the radio networking and infrastructure workflows of today’s broadcast operations.
Harris Broadcast Communications provides products, systems, and services that deliver interoperable workflow solutions that span the entire broadcast delivery chain. The Harris ONE approach brings together highly integrated and cost-effective products that are ideal for emerging media business models and for customers upgrading media operations to digital and high-definition services.
