FCC Approves Ibiquity's IBOC Technology
Washington - Oct 10, 2002 - The FCC has approved the in-band
on-channel digital broadcasting technology developed by Ibiquity
Digital Corporation for use by stations. Following an extensive review,
the FCC's decision will allow radio stations to begin immediately
broadcasting digitally using the Ibiquity-developed IBOC technology,
which has been branded HD Radio.
FM stations will be allowed to transmit IBOC signals any time of the day. AM station will only be allowed to transmit IBOC signals during the day. This is due to the skywave interference that was shown to exist in the National Radio Systems Committee (NRSC) tests earlier this year.
Ibiquity previously announced that consumer electronics manufacturers utilizing HD Radio technology will debut products at the upcoming International Consumer Electronics Show (CES) in January.
This ruling allows for broadcasters to proceed immediately with IBOC broadcasting on an interim basis while the final IBOC standards are established. Digital FM has been approved for both daytime and nighttime broadcast, AM digital for daytime broadcast. Ibiquity is working closely with the NRSC, co-sponsored by the National Association of Broadcasters (NAB) and the Consumer Electronics Association (CEA), to develop final FM and AM IBOC standards.
During the interim IBOC operations, stations will broadcast the same main channel program material in both analog and digital modes.
Ibiquity and the NAB have touted the improved audio and additional datacasting capabilities of IBOC as being the key to radio station acceptance and implementation of the technology. The broadcast community is split on its feeling. Those opposed to it feel that the audio improvement is marginal at best, and the data services are not enough to propel consumer desire. One example is that RBDS, which has provided a data stream for FM radio for 10 years, never became popular in the United States. Ibiquity is quick to point out that the RBDS data rate is very low compared to IBOC, but the example at least shows that song title and artist information is not enough for a data service.
Other technology elements would allow listeners to replay audio and access additional data services.
Ibiquity held a telephone press conference following the FCC announcement, which was listened to by Radio magazine. The publications that cover the consumer audience posed lots of questions that dealt with very basic details of digital; details that a Radio magazine reader should already know. These questions show that consumers will also require a great deal of education to understand what HD Radio is and what it can do.
The FCC Vote
The commission voted 4-0 for the adoption of IBOC. The commissioners endorsed the technology, saying that it will benefit the industry and consumers. Commissioner Kathleen Abernathy said, "We don't get many items where it's a win-win for everyone. There's no down side."
FCC Chairman Michael Powell said that he is looking forward to such a dramatic leap forward in technology. "I'm thrilled and excited to see the radio wagon train finally get to the other side."
While the ruling will not take effect until 90 days after the ruling is placed in the Public Register. Until that time, stations will still need to apply for an STA through the commission.
The FCC claims that IBOC is spectrum efficient, allowing digital operations for all existing broadcasters with no new spectrum allocation requirements. The FCC noted that although it is no longer considering the proposed approach of requiring new spectrum in TV Channel 6, this ruling does not categorically foreclose new spectrum options. In the event that new spectrum is identified for broadcast use, further consideration of both IBOC and non-IBOC out-of-band digital audio broadcasting approaches may be warranted.
Redesigned FCC ULS Search Debuts Oct 17
Washington - Oct 3, 2002 - As part of a continuing effort to
strengthen the Universal Licensing System (ULS), the FCC's Wireless
Telecommunications Bureau (WTB) will debut an extensive redesign of the
ULS License Search. Users can access the new site via the Search
Licenses link on the ULS homepage at wireless.fcc.gov/uls.
The new layout and functionality of the ULS License Search provides FCC customers more search options, better control of search criteria, and faster, easier navigation of displayed licensing information. Enhancements include customizable views of locations and frequencies associated with a license, printable page formatting, printable reference copies of authorizations and other new features that will improve performance and provide greater access to the WTB’s license database.
Links to the old system will no longer work after Oct. 17.
FCC To Issue IBOC Decision on Oct 10
On Thursday, Oct. 10, the FCC is expected to pass a ruling allowing
broadcasters to begin transmitting the Ibiquity in-band on-channel
digital format. Radio broadcasters have very mixed feelings on the
chances of success for IBOC, but this step will help IBOC further its
Several public comment periods and NRSC reviews have provided a considerable amount of data to the FCC. Ibiquity has stated that it has answered the FCC's questions to allow the commission to issue a ruling.
The action taken on Oct. 10 should be one permitting broadcasters to begin broadcasting IBOC signals. A subsequent ruling would likely name a standard, which, at this time, only the Ibiquity system has been proposed.
Webcaster Royalty Bill Pulled from House Agenda
Washington - Oct 1, 2002 - On Oct. 1, the U.S. House of Representatives was scheduled to review and vote on H.R.5469, a bill that would help webcasters remain in business while the commercial dispute with record companies and the RIAA is resolved. House Judiciary Committee Chairman F. James Sensenbrenner Jr. (R-Wis.) released the following statement:
"I requested the House leadership pull today's scheduled consideration of H.R. 5469 at the request of the interested parties. The parties involved have assured me they will reach a comprehensive agreement by Friday that will be fair to webcasters, record companies, and recording artists as well as provide the economic certainty and stability necessary for webcasters large and small to succeed. I anticipate legislation codifying this agreement will be considered by the House next week."
The Sensenbrenner bill would have delayed the Oct. 20 royalty
payment deadline by six months, allowing webcasters to complete
negotiations with the record companies. Sensenbrenner has indicated his
intention to reintroduce his bill next week if no progress is made in
the IWA/RIAA negotiations.

Audio-Technica Celebrates 40 Years
Los Angeles and Stowe, OH - Oct 5, 2002 - From its early beginnings
as a manufacturer of phonograph cartridges, Audio-Technica has expanded
over the years to become a company in the design of microphones,
wireless microphones, headphones, mixers and electronic products.
Audio-Technica continues to advance the art and technology of
electro-acoustic design with the manufacturing of products for the
professional recording, broadcast, live sound, and fixed installation
The company began in 1962 when Hideo Matsushita founded Audio-Technica Corporation in Tokyo, Japan, and introduced a moving-magnet stereo phonograph cartridge, which was sold to major audio manufacturers in Japan. During the 1960’s, A-T gained a reputation producing high-quality phono cartridges for some of Japan’s leading companies, including the legendary NHK broadcast organization. It was during that period that A-T received an award from the director of the National Industrial Research Institute, part of the Ministry of International Trade and Industry (MITI) in Japan, for the company's AT1001 tone arm. The company continued to grow and became a major producer of phono cartridges, with its moving magnet (MM), proprietary dual magnet (VM), and moving coil (MC) types, becoming the cartridges of choice for leading hi-fi consumer turntable manufacturers. To meet the market demand, Audio-Technica built a new headquarters and factory in Machida, Tokyo - a facility that remains in operation today.
During the 1970’s and 1980’s, the company continued to develop critically acclaimed phono cartridges, stereo headphones, and microphones that received rave reviews and awards from leading industry organizations, journalists, and audiophiles worldwide. In 1993, Hideo Matsushita assumed the position of chairman and Kazuo Matsushita became president of Audio-Technica Corporation, a title he holds to this day.
In 1992, Audio-Technica launched its groundbreaking AT4033 condenser microphone. The AT4033 received numerous awards and accolades from the industry and is credited as being the first high-quality, studio-grade microphone available at a price within the reach of the growing home and project studio market. The AT4033 was the cornerstone of A-T’s renowned 40 Series line of microphone and headphone products, which was augmented by the recent launch of the AT4040 cardioid condenser studio microphone in 2002. The 40 Series represents the benchmark in studio microphones for leading producers and engineers, as well as high-profile artists in all genres of music.
During the 1990’s, wireless systems became a significant product category for Audio-Technica in the MI, live sound, and fixed installation markets.

Motorola Debuts DSP Radio Design
Austin, TX - Oct 1, 2002 - In an effort to provide improved
terrestrial radio reception, Motorola Semiconductor Products Sector has
developed digital radio technology that provides enhanced sound quality
and improved signal reception for existing analog broadcasts. Designed
for home and automotive stereo systems, Motorola's Symphony Digital
Radio chipset reduces static, fading, pops and hisses, and provide
automatic tuning to eliminate adjacent-channel interference. The
technology acts on the receiving end of the transmission chain, so
radio stations will not have to install any new equipment.
Designed from the 24-bit DSP Symphony Digital Audio architecture, Symphony Digital Radio uses software algorithms to tune, filter and improve the signal in place of methods that are impossible to implement via analog circuits. Software can be downloaded to incorporate new radio features and improvements. The Symphony Digital Radio chipset can be used in any number of radio models, from the feature-rich, high-end systems to entry-level, lower-feature versions.
The FM demodulator algorithm used in Symphony Digital Radio, which separates the FM signal from the carrier, provides range extension and improved signal-to-noise ratio under weak signal conditions over traditional digital demodulation techniques. The variable intermediate frequency filter algorithm used in the Symphony chipset automatically adjusts itself to 100kHz and 200kHz band channel spacing. The Symphony's channel effects equalizer minimizes the effect of multipath, which is further reduced by a diversity antenna system.
The Symphony Digital Radio is expected to provide more than 40dB of stereo separation. Symphony-enabled radios are scheduled to be delivered to the consumer market at the end of 2003.
