Georgia Tech Tests Wireless Emergency Alert System for Visually Impaired
Atlanta -Mar 4, 2008 - The Georgia Tech Wireless Rehabilitation Engineering Research Center has successfully tested its Wireless Emergency Communications (WEC) project. Results indicate that 94 percent of blind and visually impaired test subjects found WEC to be a significant improvement over their current methods of receiving emergency alerts.
Given that 18 percent of Americans are thought to have some type of disability, and that an estimated 60 percent of Americans use wireless services, it was not surprising that the Center's survey of user needs revealed that people with disabilities are significant users of wireless products and services. Further, 65 percent of those respondents said that their wireless devices were important because of the role they play in summoning help in an emergency.
This first field test involved participants from the Georgia Radio Reading Service in a full-day study to engage the effectiveness and accessibility of this prototype emergency alerting system. Subjects ranged from sight-enhanced individuals to those who are fully blind. Additionally, the test subjects' level of familiarity and use of wireless technologies ranged from technically savvy to infrequent users.
Mobile phones with WEC custom software featured an audio-oriented interface and text-to-speech reading of emergency alerts for the visually impaired; the capability to recognize an incoming alert of critical importance and override any muted sound or vibration settings to ensure that the critical alarm was delivered; and an alert attention signal that is identical to the national EAS tone familiar to the hearing population.
WEC sent a series of SMS text messages to Cingular 3125 Smartphones provided to each test subject. WEC tested custom software that runs on a Windows Mobile OS, designed to send accessible emergency alerts to short message service-capable handsets. The custom software then presented the content of the text alert in an audio format. WEC engineers simulated the emergency alerts, employing the Common Alerting Protocol, as if they originated from the National Weather Service.
Three separate weather alerts of increasing intensity were issued to participants over a period of time. Many of the test subjects liked the idea that with each test message the alert signal got louder, indicating the severity of the event. In all three test groups, affordability was raised as an important issue. Some noted they liked the repeat option in case they did not hear it clearly the first time, and that it was superior to just receiving alerts from TV, radio or friends, in which cases the alerts might not be targeted or immediate. Others felt that the specialized software would not only benefit them, but also their family and friends who might be on public transportation, biking, hiking or anyone away from home carrying a mobile device.
Additional field tests are slated for upcoming months in 2008, including at Public Broadcasting Atlanta and the National Technical Institute for the Deaf (NTID) in Rochester, New York in June. In the NTID field test the WEC software will have the additional feature of vibration alarms that will notify the deaf and hard-of-hearing population of incoming alerts. A full report on the field tests is expected to be completed in the Fall of 2008, when all the test results and user feedback is complete. Primary funding was made possible by the U.S. Department of Education's National Institute on Disability and Rehabilitation Research.

Arbitron Debuts Personal Home Page for PPM Respondents
Columbia, MD - Mar5, 2008 - Arbitron has introduced a personal home page system for Portable People Meter survey participants designed to track reward points and encourage panelists to carry the meter every waking hour. The site is called My Meter and Me, and the personal panelist website is one of several initiatives that Arbitron has undertaken to improve PPM sample performance and increase industry confidence in the PPM measurement system.
Available in English and Spanish, the My Meter and Me website offers panelists a secure and personalized way to check their earned reward points and see how they're doing toward earning bonuses and sweepstakes entries. PPM respondents can also use the site to graphically review their hour-by-hour carry time over the last seven days, compare personal performance to others in the same household, share compliance tips with any PPM respondent in any city through an anonymous, moderated Web forum, inform Arbitron when they are traveling away from home or change their contact information, ask questions or submit comments, and participate in instant polls.
FCC Issues Update on DST and PSRA/PSSA Operation
Washington - Feb 29, 2008 - Daylight-saving time commences at 2 a.m. on March 9, 2008. Certain AM stations currently operate with Presunrise Service Authorizations (PSRA) and Postsunset Service Authorizations (PSSA). Licensees with PSRAs and PSSAs located in communities that observe daylight-saving time should use the April advanced-time powers and time periods for the period between March 9, 2008, and March 31, 2008. This adjustment is necessitated by the enactment of the U.S. Energy Policy Act of 2005 that extended the effective period for daylight-saving time into March for the first time.
Questions about and reports of potential interference from PSRA and PSSA operation during March 2008 can be addressed to Charles Miller, Susan Crawford or Son Nguyen of the FCC's Audio Division at 202-418-2700.
MRC Rejects PPM in Philly and NYC
New York - Mar 3, 2008 - In January, the Media Ratings Council (MRC) denied accreditation of the Aribitron Portable People Meter (PPM) system in Philadelphia and New York. The notice was revealed in Arbitron's annual filing with the SEC.
Arbitron attributes the decision to old field tests, and the ratings company is hopeful that data gathered from he field trials currently underway will convince the MRC to change its mind. Arbitron's current test has increased the sample size, which was one of the MRC's concerns. The MRC was created following a Congressional call in 1964 to establish standards for media ratings.
Arbitron has already delayed the PPM rollout in the planned markets.

IP Codec Interoperability via SIP Demonstrated
Munich, Germany - Feb 29, 2008 - Audio-via-IP Experts Group members Tieline Technology, Orban/CRL, Mayah Communications, AETA, Prodys, Telos, AEQ, AVT and Digigram recently met in Munich to test IP Interoperability using Session Initiation Protocol (SIP) to connect according to EBU-approved standards.
PJ Fall, Tieline business development manager in Europe, explained that SIP-compatible codecs that are registered to SIP servers can dial and connect to other codecs and VoIP devices without knowing the IP address of the receiving unit. This simplifies remote broadcasting over IP because there is no need for codecs to acquire static IP addresses in order to connect - even if they move between different locations.
Lars Jonsson of Swedish Radio acting on behalf of the EBU thanked manufacturers their work to prepare the successful meeting, despite the different commercial interests. "On behalf of all the EBU-team, I would like to thank you very much for the hard job you all did in Munich. I was so impressed to see you all work together over company and country borders so patiently to solve all small details in good spirit."
When IP codecs connect via SIP, they exchange information about coding algorithms, sample rates and connection bit-rates.

NTI Adds Functions to Minirator MR-Pro
Liechtenstein - Feb 28, 2008 - NTI has extended the functions of the analog signal generator the MR-Pro by introducing the new firmware V2.01. Now Minirator MR-Pro measures the impedance and phase of the connected load and calculates the related power for 70V or 100V distributed loudspeaker systems. An enhanced cable test function and new test signals for amplifier and noise measurements are also added.
XLR-audio cables may be miswired in the soldering process or break during usage. The extended MR-Pro cable test function detects all common XLR wiring faults with a description to the user, such as "2-3 Crossed" or "Pin 2 open." This result gives accurate instructions for the repair of the cable.
Individual user test signals may be stored as uncompressed WAV files in the MR-Pro memory. NTI also offers WAV signals for this purpose. In addition, a set of 1/3 octave, narrow-band pink noise signals is available to measure the airborne noise isolation index. A set of square wave signals is also available for a quick diagnosis of amplifier behavior.
The new firmware is free of charge and available for download at the Minirator support website at support.nti-audio.com/mr2.
