NAB Launches Technology Advocacy Program
Washington - Apr 9, 2007 - The National Association of Broadcasters has created a long-term technology advocacy program to seek and facilitate development and commercialization of new technologies for radio and TV. The multi-year, multi-million dollar program will be named NAB Fastroad (Flexible Advanced Services for Television and Radio On All Devices).
NAB Fastroad is a result of the NAB Technology Advocacy Committee in accordance with the sustained priority placed on technology by NAB Joint Board Chairman Bruce Reese and NAB President David Rehr. Consisting of NAB Board members, the NAB Technology Advocacy Committee held its first meeting in March 2006 and subsequently conducted a year-long decision-making investigation, including briefings by outside consultants, economic and technical analysis of technology developments, and a technical review of potential projects through a technology discovery group process. Based on this work, the NAB board of directors decided unanimously in January 2007 to launch the program and NAB's executive committee approved organizational details in late March.
NAB Fastroad will be managed overall by a steering committee consisting of NAB executive staff, board members and other representatives from NAB broadcast member organizations. Project selection and implementation will be handled by a technical committee of selected NAB member company engineers and staff from the NAB Science and Technology Department. Participation by NPR Laboratories and MSTV has also been established to coordinate with other ongoing technical programs in the radio and TV broadcasting sectors. The program will principally concentrate on technologies and services related to over-the-air digital transmission.
IBS Partners with Backbone to Create Internet Radio
Worcester, MA - Apr 9, 2007 - The Intercollegiate Broadcasting System (IBS) has partnered with Backbone Networks to create an Internet radio network called the Digital Radio Network. Through this network, student-operated stations can syndicate live and produced programming among member stations, as well as automatically access royalty-free programming from worldwide third-party sources, such as Trakheadz.com. The network will use Backbone's client-server radio software.
The network builds on MPEG-4 AAC as its streaming format. This standard ensures universal acceptance across all listening platforms, and enables each school to partner with the Apple's Itunes store in preparing material, including artist/album annotation and cover art images that display to listeners' free Quick Time or Itunes players. Stations only need a Macintosh computer, a microphone and a DSL connection to be on the air. All program automation software is provided by Backbone, as well as all server storage, streaming broadcast bandwidth and automated reporting software.
IBS Digital Network member stations, as non-commercial entities, will be covered by a maximum royalty obligation of $500 per year, according to the recent CRB ruling. Stations will be able to generate RIAA-compliant listener logs specifying the per-performance records required by the CRB.

Tieline Launches Interoperability Over IP with other Brands
As telco providers cut back and in some cases discontinue offering ISDN service in the United States and Europe, the European Broadcast Union (EBU) is establishing operability standards that will allow IP codecs from different manufacturers to communicate with each other. At NAB2007, Tieline Technology demonstrated codecs that are compliant with the new audio-over-IP interoperability standards issued by the EBU.
While most ISDN codecs have been able to establish ISDN connections regardless of the manufacturer for more than 10 years, IP connectivity does not always provide the same cross-compatibility. The EBU is establishing a global standard for broadcasting via IP networks and interoperability between codec brands.
Part of this compatibility includes the use of the Real-time Transport Protocol (RTP), which defines a standardized packet format for delivering audio and video over the Internet, and Session Initiation Protocol (SIP ), an Internet application-layer protocol that allows audio and video sessions to be established over the Internet. SIP provides many features to simplify a codec connection across the Internet including the ability to register a name or number to a codec to simply dialing via a SIP server; a mechanism to allow the best algorithm that is common to both codecs to be used; correctly setting sample rate, bit-rate and mono/stereo mode; and an option to send only, receive only or standard send/receive mode.
Tieline plans to extend its support for phone voice mode to include SIP VoIP over IP connections. Tieline now offers voice-mode connectivity on POTS, GSM, ISDN and IP.

X-Digital XDS-Pro 4
The XDS-Pro 4 satellite receiver is designed as a professional device enabling networks with up to four audio outputs with 32 relays. Each live stream can be routed to any of the balanced outputs. Media files can be transmitted into local Flash, a local hard disk or onto a mounted Network File Server device. Audio files residing on the mounted device can be inserted into live or recorded media being output via the MPEG decoder, providing localization into live and stored programming.The XDS-Pro is capable of recording and playing back any broadcast channel. All units are equipped with as many as 32 programmable Form-A relays that can be actuated via network control or ancillary data channels, providing a legacy interface for many existing radio station automation systems.
Inovonics Band Scanner
FM scanning receiver
The Band Scanner is a tool to evaluate FM broadcast band congestion and to log station identification parameters. The system is powered by the USB port of any Windows PC. The Band Scanner generates a graph showing RF level vs. frequency for every station in the market. It then analyzes each carrier and creates a station list. Stations with an RDS presence are further refined to show all the radio data groups being transmitted. Its interface is like a portable radio: It may be tuned manually through the receiver screen or by double-clicking a point on the spectrum plot or an entry on the station list. Spectrum plots may be saved as jpg or bmp files. The RDS data error level is graphed in a separate window on the receiver screen. The program can be monitored with headphones plugged into a standard 1/8" jack.
Pristine Systems Informant
Audio silence monitor
The Informant is an audio silence monitor with e-alterts. The unit continuously monitors incoming audio using high-speed A/D converters with a specially weighted algorithm to detect silence below a user adjustable threshold. When the length of silence on any channel exceeds the user-determined duration, an e-mail/SMS text message is sent to the corresponding e-mail address from that channel's time schedule.
