FCC Continues to Support Odd-lengthFederal Political Spots

Washington - Nov 14, 2003 - The FCC denied an NAB petition toreinstate a previous ruling (in effect from 1994 until 1999) thatstations are not required to sell odd-length time (for examplefive-minute ads) to federal candidates. The FCC held that broadcasters'obligation to provide reasonable access to a legally qualified federalcandidate precluded any blanket ban on non-standard length time.Stations still may evaluate requests for time on a case-by-case basis,taking into consideration: (1) how much time was previously sold to thecandidate; (2) disruption to station's regular programming; (3)likelihood of equal opportunity requests by opposing candidates; and(4) the timing of the request.

FCC Makes AdditionalUnlicensed Spectrum Available

Washington, DC - Nov 13, 2003 - The FCC has made available anadditional 255MHz of spectrum in the 5.470 to 5.725GHz band forunlicensed devices.

In the Report and Order approved on Nov. 12, the Commission made thespectrum available for use by unlicensed National InformationInfrastructure (U-NII) devices, including radio local area networks(RLANs), operating under Part 15 of the FCC�s rules. Thisincreases the spectrum available for use by unlicensed devices in the5GHz region of the spectrum by nearly 80 percent and is a significantincrease in the spectrum available for unlicensed devices across theoverall radio spectrum. The FCC expects that this action will alsoharmonize the spectrum available for these U-NII devices throughout theworld, enabling manufacturers to reduce product development costs byallowing the same products to be used in many parts of the world.

The new spectrum is part of an effort to enable continued growth andinnovation in wireless broadband services, including services offeredby wireless Internet service providers (WISPs). WISPs use unlicenseddevices to provide a broadband alternative for rural and underservedareas. Although they are a relatively nascent industry, theirdeployment rates have been increasing rapidly.

In addition to making additional spectrum available for U-NII devices,the Commission also adopted several allocation changes consistent withthe results of the 2003 World Radio Conference and an agreement reachedwith the U.S. Department of Defense, the National Telecommunicationsand Information Administration (NTIA). These changes will ensure thatcritical Federal Government operations are protected from harmfulinterference. In addition to the allocation changes, to provide federalusers with additional protection from harmful interference, the orderrequires that U?NII devices operating in the 5.250 to 5.350GHz and the5.470 to 5.725GHz bands use dynamic frequency selection (DFS), alisten-before-talk mechanism and transmit power control (TPC).

Report and Order FCC 03-287, ET Docket No. 03�122.

Arbitron Updates CensusData

New York - Nov 14, 2003 - In its efforts to provide the mostup-to-date survey information, Arbitron has updated the census dataused to determine market rankings for the Fall 2003 ratings period. Theradio ratings service has created an online tool to compare the Fall2003 and Spring 2003 12+ population estimates. To use the tool, go tothis link at the Arbitron website.

The Market-Specific Population Estimate Comparison Tool provides aside-by-side comparison of market population estimates to show howmarket estimates have changed from Spring to Fall 2003. The populationestimates used for the comparison are those updated yearly byClaritas.

Arbitron notes that certain factors are important to consider whenviewing the data. Differences between a market's new populationestimates and the current estimates should be viewed as technicaldifferences, not actual movement of people in or out of a market. Thesedifferences are a consequence of the estimating process. While the datawere updated using a variety of federal, state and local sources, noneof these sources are as accurate as the Census itself. In most casesthis process is very reliable. In certain situations, however, there ispopulation movement that is undetected or misreported by thestatistical sources used to update population estimates.

To see the current rankings of the surveyed radio markets, follow this link.

WNNK to Install Interleaved HD RadioAntenna

Raymond, ME - Nov 20, 2003 - Dielectric Communications is workingwith Cumulus on the installation of the Dielectric's first interleavedanalog/IBOC FM antenna. WNNK Engineering Manager Dave Supplee suggestedthe Harrisburg, PA, market to Cumulus because of the mountainousterrain and multipath issues. Gary Kline, corporate director ofengineering agreed because the location should provide an opportunityto evaluate IBOC in a severe multipath location.

Dielectric�s development of the interleaved antenna design hascreated an improvement in isolation between the antenna elements. As aresult of the increased isolation, the electrical performance of theantenna is stable, effectively eliminating elevation and azimuthalpattern deviation between the analog and digital signals.

Combined with the use of circulator technology in the RF system,Dielectric expects this design to meet or improve on the 36dB isolationspecification for IBOC. Both scale model and full-size tests of theinterleaving scheme have shown no change in the antenna patterns byadding the IBOC bays to an existing analog antenna.

WNNK recently took delivery of the two-bay, full-wave-spaced DielectricDCR-M side-mounted antenna. This antenna will radiate the Class BFM�s analog signal. This month, the interleaved two-bay IBOCantenna and IBOC transmitter will be installed.

Coding Technologies, BeijingE-World form Joint Venture

Stockholm, Sweden - Nov 18, 2003 - Coding Technologies, the creatorof SBR codec enhancement, and Beijing E-World Technology, the creatorof the Chinese Enhanced Versatile Disc (EVD) format, have establised ajoint venture, Beijing Media Works, to create and license a new audiocodec. This new SBR-enhanced codec, EAC 2.0, is already specified inthe EVD format and will also be targeted for use in other Chineseapplications.

Beijing Media Works is based in Beijing, with additional engineeringfacilities in Nuremberg, Germany. This selection of office locationswill allow for close business and engineering collaboration between thejoint venture and both parent companies.

SBR-enhanced EAC will be licensed exclusively in Greater China by thejoint venture and in the rest of the world by CodingTechnologies.

Spectral Band Replication (SBR) is a unique bandwidth-extensiontechnique that enables audio codecs to deliver the same quality at halfthe bit-rate. In practice, SBR is wrapped around a core perceptualaudio codec to enhance its efficiency in a backward- andforward-compatible way. Based on the principle that the high and lowfrequencies of an audio signal are highly correlated, SBR-coupledcodecs use the core to only encode the low frequencies and use the SBRto encode the high frequencies with low overhead.

Enhanced Audio Codec (EAC) is an enhanced audio codec developed andowned by Beijing E-World that uses a unique perceptual model tocompress the audio signal by using the redundancy as well as therelevancy. The EAC codec supports mono, stereo and 5.1 surround-soundmodes for encoding and decoding. EAC is part of the EVD systemspecification.
