Arbitron Accelerates Start Date for Cell-Phone-Only Sampling
New York - Oct 2, 2008 - Arbitron has announced plans to introduce cell-phone-only households to its diary survey sample, starting with 50 markets for the Spring 2009 survey. This is six months earlier than the company first planned. Arbitron will also establish a sample-quality benchmark in diary markets for persons aged 18-54 equal to a Designated Delivery Index of 80. Reporting of the diary market sample performance versus the new benchmark will begin with the current Fall 2008 survey.
"The Radio Advisory Council and the Diary Market Owner Operator Caucus, which have been working closely with Arbitron on these matters since last year, deserve credit for encouraging Arbitron to speed the introduction of cell-phone-only sampling in diary markets and to introduce a sample quality benchmark for 18-54 year olds, the demographic on which most radio advertising is focused," said Steve Morris, chairman, president and chief executive officer, Arbitron. "This new benchmark will narrow the present sample guardrails in diary markets and add greater transparency to the sample quality in all diary markets."
Beginning with the Spring 2009 survey, Arbitron will add cell-phone-only households to the sample frame in 50 diary markets. Arbitron also plans to expand cell-phone-only household sampling to a total of 125 diary markets with the Fall 2009 survey. The specific market lists are not yet finalized. Portable People Meter markets already include cell-phone-only households in their panels.
Starting with the Fall 2008 survey, Arbitron plans to establish a sample benchmark for persons aged 18-54 in all diary markets equal to a Designated Delivery Index of 80. The new benchmark is based on the same metric the company uses to gauge its PPM sample quality performance. The DDI is defined as the actual sample size for a given demographic (persons aged 18-54, in this case) divided by the target sample size times 100. Should the actual sample performance fall below an 80 DDI in a given market/survey, Arbitron will focus its efforts to bring the sample performance above that threshold in subsequent surveys.
FCC Sets Plans for 700MHz Public Safety Block
Washington - Sep 25, 2008 - The Federal Communications Commission adopted a third further notice of proposed rulemaking that proposes to license the 700MHz D Block spectrum as part of a revised 700MHz public/private partnership for a nationwide, interoperable broadband network in the 700MHz band. The notice proposes to retain a public/private partnership framework for the 700MHz band absent other sources of funding. It proposes a modified set of rules to govern the D Block and a revised auction plan for assigning D Block licenses.
Specifically, the FCC proposes to use the competitive bidding process to determine whether, based on greatest population coverage and highest bid(s), the D Block spectrum would be licensed to a single licensee on a nationwide basis or to regional licensees on the basis of 58 public safety regions. If the D Block is licensed on a regional basis, the auction results also would determine the particular air interface technology that would be deployed across the nation by the D Block licensee(s) when building out the interoperable broadband network(s), which would facilitate the ability of public safety entities to communicate outside of their home regions. With regard to the D Block license term and performance requirements, the notice proposes to extend the license term to fifteen years and to adopt performance benchmarks applicable at the fourth, tenth, and fifteenth years under the life of the license(s).
The Notice also proposes and seeks comment on rules involving significant clarifications and revisions of the respective obligations of the D Block licensee(s) and the public safety broadband license regarding the construction and operation of the shared wireless broadband network.
The clarifications and revisions address the use of spectrum in the shared wireless broadband network (including requirements regarding public safety priority access to commercial capacity in emergencies), the technical requirements of the shared wireless broadband network (including detailed proposals relating to interoperability, robustness, capacity, quality of service, and security), the coverage requirements of the broadband network(s), and the respective operational roles of the D Block licensee(s) and the public safety broadband licensee.
Because the D Block did not meet its $1.3 billion reserve price in the 700MHz auction held in early 2008, the FCC sought comment in May on whether it should revise the 700MHz public/private partnership and reauction this spectrum. These rules included the creation of a 10MHz license in the D Block to be part of a public/private partnership with the adjacent 10MHz of spectrum dedicated to a public safety broadband license. To ensure that all aspects of this critical initiative are given careful consideration, the Commission seeks additional public comment on this latest proposal, which was largely developed from the input, ideas and recommendations received from public safety organizations and officials, government representatives, wireless carriers and manufacturers across the country.
The public comment period for this Notice will begin once it is published in the federal registry and run for a period of 30 days, with reply comments due within 40 days from federal register publication.

Ibiquity Releases Reference Designs for Portable and USB Products
Shenzhen, China - Oct 8, 2008 - Ibiquity Digital is offering its licensed HD Radio developers a reference platform for low-cost, low-power, battery-powered portable and USB-connected HD Radio products. Available for demonstration for the first time at the Hong Kong Electronics Show, the developers' package includes schematics, bill-of-material, layout and software.
This provides portable product manufacturers with a standard reference design to enable quicker time to market development. The reference platform is based on Samsung EM's Core-CR module measuring 20.0 x 13.0 x 2.3mm. The Core-CR module is a surface-mount device (SMD) package, which consists of a dual chip (RF -IF Peripheral and Baseband), dedicated memory SDRAM (64Mbit), and flash memory (8Mbit). The Samsung Core-CR Module has a total power consumption of 210mW and allows for 15 hours of continuous operation.
The portable HD Radio unit uses an Atmel AVR32 (AT32UC3A) as its host microprocessor. The portable reference platform has support for MP3, USB on-the-go, and an SD card interface. The reference has monochrome graphic LCD 128 x 64 and uses two AA alkaline batteries.
Ibiquity states that the USB design will greatly assist its partners in developing HD Radio data services and advanced visual-radio user interfaces. The USB reference design provides manufacturers with a path to add HD Radio technology to a PC, a portable navigation device or any device featuring a USB port.
The reference platform is capable of working with various new-generation radio modules (using Ibiquity's 2129 or 2023 interfaces). With the ability to accept two modules, the reference is suitable for developing products requiring a second tuner for data applications. The reference is provided in a hide-away-box form factor measuring 145 x 100 x 42mm and requires only USB and antenna connections.
The USB HD Radio reference design uses Atmel's AVR32 (AT32UC3B) as its slave microprocessor. Any attached USB host processor is able to receive audio and communicate with the reference platform over standard protocols (USB audio-class/USB HID-class), thereby requiring no proprietary drivers. In addition to USB audio, the reference design provides analog audio output and digital SPDIF output. The device can be powered by USB or an external supply.

NTI Extends Minirator MR-Pro Capability
Beginning in fall 2008, new deliveries of MR-Pro will include extended mass storage RAM capacity of 512MB, allowing storage of 16 times more test signals. The extended memory capacity enables clients to store all their important audio test signals, audio announcement and favorite listening tracks of up to 80 minutes in the non-volatile memory. All earlier MR-Pro units can be factory upgraded with the new memory.
A new firmware version 2.10 has been released for the MR-PRO, offering compatibility with the Apple MAC OS versions 10.4 onwards running on G4/ G5 as well as on the new X86 architectures. Also, in response to customer feedback the impedance measurement of the MR-PRO now handles power calculations for 35V, 140V and 200V voltage distribution systems. This test of the calculated apparent power simplifies the load verification in distributed loudspeaker systems.
Along with the firmware V2.10, a WAV file set with sinusoidal subsonic frequencies between 1Hz and 10Hz is available for download. Each file generates a pure, low distortion sinusoidal waveform at a fixed frequency. With this set of wave files the MR-PRO serves as a signal stimulus for vibration sources.
Sound Devices Updates 788T Firmware
San Francisco - Oct. 3, 2008 - With the latest revision of firmware, the 788T gains several key features including improvements in metadata handling, where changes are applied to files across all attached drives, and all files for a given take. This helps to further streamline the communication between crew in the field and in post. To allow for the connection of digital microphones, users can now enable the 788T's on-board sampling rate converters when needed to support multiple AES42 microphones. This makes the 788T one of the first recorders to allow for the connection of an AES42 digital microphone.
As multi-microphone surround recording becomes more prevalent, the firmware helps provide several new headphone modes for the 788T to facilitate monitoring multi-mic surround recording in the field. The update also provides new capabilities to the limiter, to offer the user more recording options.
Sound Devices Updates Wave Agent Utility Software
San Francisco - Oct. 3, 2008 - Compatible with both Mac and PC platforms, the new software provides comprehensive metadata editing tools for WAV and associate metadata files, as well as file playback for sound files recorded with the company's 7-Series Digital Recorders.
Available immediately, as a no-charge download from the company's website, Wave Agent helps users manage and edit Broadcast Wave file metadata and iXML metadata as well as allowing for batch editing of large file libraries. Wave Agent users are offered the flexibility to modify sound report templates to meet the needs of each project. Additionally, the software generates sound reports in PDF format, ensuring the reports can be viewed regardless of the editing application being used.
The software's interface is user-friendly and is designed for speed, making sense of the often-complex metadata generated by the current generation of field recorders. Wave Agent has a large display for time code, actual time, and remaining time counters.
In addition to the administration of metadata, the software allows for the playback and conversion of any type of WAV file (poly, mono, bit depth, sample rate). Wave Agent converts WAV file between monophonic and polyphonic formats. It also features an intelligent batch mono-combine function. Users also have the ability to control the gain, pan, solo and mute tracks during playback. To help correct sync issues in post, Wave Agent users can modify time code frame-rates to correct mistaken frame-rate settings.
