Harris Corporation to Receive Technical Emmy(R) Award for ATSC Broadcast Transmission System RF Filters

CINCINNATI, Oct. 23 /PRNewswire-FirstCall/ -- Harris Corporation (NYSE:HRS) , an international communications and information technology company, will be awarded a Technology & Engineering Emmy(R) Award from the National Academy of Television Arts and Sciences (NATAS) for developing special transmission filters that help broadcasters improve the quality and reduce the costs of operating digital television signals. Harris will be presented the award for developing the ATSC Broadcast Transmission System RF Filters at a ceremony January 7, 2008, at the International Consumer Electronics Show (CES) in Las Vegas.

The ATSC RF filter technology, which was awarded a U.S. patent in 2005, was pioneered by Robert J. Plonka, principal engineer with Harris Corporation (now retired), to overcome potential quality and interference problems stemming from operating adjacent analog and digital channel assignments. The resulting band-pass RF filters maintain highly reduced side-band emission levels to eliminate interference with other signals in adjacent channels, particularly when broadcasting at full power DTV with dual-purpose capability to use that same filter as an adjacent channel combiner.

In November of 2000, KFSN-TV, the ABC affiliate in Fresno, Calif., became the first station to employ the technology in its broadcast operation, broadcasting its digital signal on VHF channel 9. Today, the ATSC Broadcast Transmission System RF Filters have become an industry-standard component deployed across a variety of ATSC DTV transmission platforms by third-party vendors

Tim Thorsteinson, president of Harris Broadcast Communications, said, "We're thrilled to have been selected by NATAS for our efforts to advance ATSC signal transmission through the use of sharply tuned band-pass RF filters. Today, DTV stations in the United States use these RF filters to stay in strict compliance with FCC specifications. Ensuring that DTV signals maintain highly reduced side-band emission levels means that adjacent spectrum may be used reliably for other purposes without the risk of interference."
