FCC Continues to Support Odd-length Federal Political Spots
Washington - Nov 14, 2003 - The FCC denied an NAB petition to reinstate a previous ruling (in effect from 1994 until 1999) that stations are not required to sell odd-length time (for example five-minute ads) to federal candidates. The FCC held that broadcasters' obligation to provide reasonable access to a legally qualified federal candidate 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 the candidate; (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 Additional Unlicensed Spectrum Available
Washington, DC - Nov 13, 2003 - The FCC has made available an
additional 255MHz of spectrum in the 5.470 to 5.725GHz band for
In the Report and Order approved on Nov. 12, the Commission made the spectrum available for use by unlicensed National Information Infrastructure (U-NII) devices, including radio local area networks (RLANs), operating under Part 15 of the FCC’s rules. This increases the spectrum available for use by unlicensed devices in the 5GHz region of the spectrum by nearly 80 percent and is a significant increase in the spectrum available for unlicensed devices across the overall radio spectrum. The FCC expects that this action will also harmonize the spectrum available for these U-NII devices throughout the world, enabling manufacturers to reduce product development costs by allowing the same products to be used in many parts of the world.
The new spectrum is part of an effort to enable continued growth and innovation in wireless broadband services, including services offered by wireless Internet service providers (WISPs). WISPs use unlicensed devices to provide a broadband alternative for rural and underserved areas. Although they are a relatively nascent industry, their deployment rates have been increasing rapidly.
In addition to making additional spectrum available for U-NII devices, the Commission also adopted several allocation changes consistent with the results of the 2003 World Radio Conference and an agreement reached with the U.S. Department of Defense, the National Telecommunications and Information Administration (NTIA). These changes will ensure that critical Federal Government operations are protected from harmful interference. In addition to the allocation changes, to provide federal users with additional protection from harmful interference, the order requires that U?NII devices operating in the 5.250 to 5.350GHz and the 5.470 to 5.725GHz bands use dynamic frequency selection (DFS), a listen-before-talk mechanism and transmit power control (TPC).
Report and Order FCC 03-287, ET Docket No. 03–122.

Arbitron Updates Census Data
New York - Nov 14, 2003 - In its efforts to provide the most
up-to-date survey information, Arbitron has updated the census data
used to determine market rankings for the Fall 2003 ratings period. The
radio ratings service has created an online tool to compare the Fall
2003 and Spring 2003 12+ population estimates. To use the tool, go to
this link at the Arbitron website.
The Market-Specific Population Estimate Comparison Tool provides a side-by-side comparison of market population estimates to show how market estimates have changed from Spring to Fall 2003. The population estimates used for the comparison are those updated yearly by Claritas.
Arbitron notes that certain factors are important to consider when viewing the data. Differences between a market's new population estimates and the current estimates should be viewed as technical differences, not actual movement of people in or out of a market. These differences are a consequence of the estimating process. While the data were updated using a variety of federal, state and local sources, none of these sources are as accurate as the Census itself. In most cases this process is very reliable. In certain situations, however, there is population movement that is undetected or misreported by the statistical sources used to update population estimates.

WNNK to Install Interleaved HD Radio Antenna
Raymond, ME - Nov 20, 2003 - Dielectric Communications is working
with Cumulus on the installation of the Dielectric's first interleaved
analog/IBOC FM antenna. WNNK Engineering Manager Dave Supplee suggested
the Harrisburg, PA, market to Cumulus because of the mountainous
terrain and multipath issues. Gary Kline, corporate director of
engineering agreed because the location should provide an opportunity
to evaluate IBOC in a severe multipath location.
Dielectric’s development of the interleaved antenna design has created an improvement in isolation between the antenna elements. As a result of the increased isolation, the electrical performance of the antenna is stable, effectively eliminating elevation and azimuthal pattern 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 isolation specification for IBOC. Both scale model and full-size tests of the interleaving scheme have shown no change in the antenna patterns by adding the IBOC bays to an existing analog antenna.
WNNK recently took delivery of the two-bay, full-wave-spaced Dielectric DCR-M side-mounted antenna. This antenna will radiate the Class B FM’s analog signal. This month, the interleaved two-bay IBOC antenna and IBOC transmitter will be installed.

Coding Technologies, Beijing E-World form Joint Venture
Stockholm, Sweden - Nov 18, 2003 - Coding Technologies, the creator
of SBR codec enhancement, and Beijing E-World Technology, the creator
of the Chinese Enhanced Versatile Disc (EVD) format, have establised a
joint venture, Beijing Media Works, to create and license a new audio
codec. This new SBR-enhanced codec, EAC 2.0, is already specified in
the EVD format and will also be targeted for use in other Chinese
Beijing Media Works is based in Beijing, with additional engineering facilities in Nuremberg, Germany. This selection of office locations will allow for close business and engineering collaboration between the joint venture and both parent companies.
SBR-enhanced EAC will be licensed exclusively in Greater China by the joint venture and in the rest of the world by Coding Technologies.
Spectral Band Replication (SBR) is a unique bandwidth-extension technique that enables audio codecs to deliver the same quality at half the bit-rate. In practice, SBR is wrapped around a core perceptual audio codec to enhance its efficiency in a backward- and forward-compatible way. Based on the principle that the high and low frequencies of an audio signal are highly correlated, SBR-coupled codecs use the core to only encode the low frequencies and use the SBR to encode the high frequencies with low overhead.
Enhanced Audio Codec (EAC) is an enhanced audio codec developed and owned by Beijing E-World that uses a unique perceptual model to compress the audio signal by using the redundancy as well as the relevancy. The EAC codec supports mono, stereo and 5.1 surround-sound modes for encoding and decoding. EAC is part of the EVD system specification.
