Exhibition to emphasize power of supplementary audio services for HD Radio
CINCINNATI, March 17, 2005 – Harris Corporation's (NYSE: HRS) Broadcast Communications Division (BCD) will showcase its support of the Tomorrow Radio Project, spearheaded by National Public Radio (NPR), through a continuous Tomorrow Radio demonstration at NAB2005. Tomorrow Radio, currently in the midst of a multiyear testing phase, enables radio stations to broadcast multichannel services, including secondary audio and data channels, as part of the HD Radio platform. The secondary services are delivered over the same transport stream as a station's main analog channel services, taking full advantage of existing bandwidth. Harris has been providing HD Radio transmission equipment for NPR's testing since the project's inception in 2003.
"Tomorrow Radio is a shining example of HD Radio's capabilities," said Debra Huttenburg, vice president and general manager of the Harris BCD's Radio Broadcast Systems business unit. "The ability to divide an HD Radio signal into two independently programmed channels is a huge forward leap for terrestrial radio. Harris has proven it can deliver a complete HD Radio transmission solution that allows broadcasters to deliver two high-quality channels over existing bandwidth. This demonstration will clearly illustrate Harris' efforts in bringing to market flexible, end-to-end transmission solutions that drive the adoption of digital radio."
At NAB2005, Harris will provide a continuous Tomorrow Radio demonstration featuring its Mini-HD Series of separate amplification transmitters, FLEXSTAR HDI-100 importer, and DEXSTAR® HD Radio exciter. Visitors to the booth can learn how the HDI-100 importer multiplexes supplemental audio and data services together en route to the DEXSTAR exciter, which modulates the multiplexed signal and controls the Mini-HD transmitter to drive the multichannel services to the receiver. The cost-effective Mini-HD Series provides low-power FM HD Radio systems with the same benefits that distinguish Harris' market-leading, higher-power transmitters from the competition.
The Mini-HD Series offers four models with different power levels (ranging from 10-600 watts) to serve the varying needs of different customers and market sizes. All Mini-HD transmitters integrate the Harris DEXSTAR HD Radio exciter with a highly linear RF amplifier in a single rack cabinet. Other standard features include rack-mount UPS and ePAL® audio routing systems. The ePAL exciter/program audio interface automatically ensures audio path integrity and provides terminal gear applications for synchronization, distribution and sample rate conversion. Options include Harris' NeuStar HD/FM pre-codec processor, which maintains the cleanest possible digital audio, even at reduced bit rates. All four transmitters meet FCC and iBiquity HD Radio standards for use in the United States.
The HDI-100 importer is part of the new FLEXSTAR family of radio products, which also includes the HDE-100 exporter. While the importer enables data services and the supplemental audio chain, the HDE-100 exporter multiplexes the main channel audio with feeds from the importer en route to an STL system.
