    Broadcast Electronics Demos HD Radio with Four Channels, Closed Captioning
    Quincy, IL - Apr 17, 2006 - At NAB2006, Broadcast Electronics (BE) will host the first public demonstration of four audio program channels via HD Radio plus a closed-caption radio service for the hearing impaired designed by NPR Labs. The captioning runs on part of the Advanced Application Services data stream. The demonstration is sponsored by BE in partnership with Ibiquity Digital with participation from NPR.

    The demonstration is representative of how stations might broadcast multiple services over HD Radio. A news/talk program will be carried on the main channel, with two music formats on the HD2 and HD3 channels. A fourth multicast channel will carry radio reading services for the visually impaired. A separate data channel illustrates closed captioning of the news/talk program for the hearing impaired.

    Mike Starling, chief technology officer of NPR Labs, said, "This demonstration features technology innovation from BE and proves that the concept is not just viable, but also within reach."

    The demonstration will take place at BE's booth N1808. Representatives from NPR Labs will be available at the booth during exhibit hours.

    Harris Sells first High-Power Tube Transmitter for HD Radio
    Cincinnati - Apr 6, 2006 - Harris has sold its first HT-HD+ tube-type HD Radio transmitter to Clear Channel radio stations WCOL-FM in Columbus, OH, and KRFX-FM in Denver. The HT-HD+, to be formally announced at NAB2006, marks Harris'' foray into the HD Radio market with high-power, tube-type transmitters. Dan Mettler, regional vice president of engineering for Clear Channel Radio, will supervise the installation and testing of the first HT-HD+ transmitter at WCOL. The KRFX installations (two 22kW models) will follow shortly after, with a combined TPO of 41kW.

    The HT-HD+ is expected to be available for shipping around July 2006.

    Audemat-Aztec Partners with Global Security Systems

    Harris, NPR Labs to Demo HD Radio Services for Hearing and Visually Impaired
    Cincinnati and Washington - Apr 4, 2006 - Harris and National Public Radio Labs will offer a technology-driven display at NAB2006 demonstrating how HD Radio can offer radio service to listeners who are hearing and/or visually impaired. The demonstrations will be held at the Harris booth C807.

    The demo will preview captioned radio text for the hearing impaired and extended hybrid mode operation of radio reading services for the visually impaired sent over the HD Radio air chain. The complete proof-of-concept design will feature Harris transmission equipment for insertion of the program material in the HD Radio multicasting stream, and Kenwood and Boston Acoustics radios to receive the dedicated Radio Reading Service channel and a radio captioning display of an NPR program.

    Many NPR Member stations broadcast Radio Reading Services for the blind, a program that offers readings of books and publications over analog subcarriers, to about one million weekly listeners, or 10 percent of the potential visually impaired audience. The addition of this service to the HD Radio multiplex of audio and text-based services will provide easier access for listeners and increase reading service audience size. Similarly, the HD Radio multiplex can carry the new captioned radio text service to deliver news, weather and other important information to the hearing impaired.

    FCC's Copps Joins Regulatory Face-Off at NAB2006
    Washington - Mar 30, 2006 - FCC Commissioner Michael Copps will join Commissioners Jonathan Adelstein and Deborah Taylor Tate at the NAB2006 Regulatory Face-off at NAB2006 on April 25. The session, part of the Business, Law and Regulation Conference at NAB2006, will feature all three FCC commissioners as they discuss current regulatory topics facing broadcasters.

    Notes on Booth Numbers
    Navigating the show floors at NAB can be difficult. Here's a breakdown of the different halls and how the booths are arranged.

    N-North Hall
    SU-South Hall upper level
    SL-South Hall lower level
    OE-Outdoor exhibits between the Central and South Halls
    R-RTNDA exhibits in the Hilton
    Lobby-Booths in the lobby areas. The lower booth numbers are in front of Banners restaurant outside the North Hall. The higher booth numbers, such as the SBE in Lobby 28, are near the Broadcast Engineering Conference session rooms S220 through S227.

    In general, the booth number follows a grid. The first digits represent an aisle (or column), the last two digits represent a row. In the North Hall, this is easy to follow. When you stand at the hall entrance near Banners Restaurant, N400 is in the front to the right and N4538 is in the back and to the left.

    The Central Hall is also simple. The aisles start from the front. When standing at the entrance with the bus loading area behind you, C101 is in the front on the left, C11547 is in the back on the right.

    The South Halls can be confusing because the grid system is divided into the front and rear portions of the halls. Standing at the entrance with the Monorail behind you, the lower aisle numbers are on the left and they increase as you move right. The confusing part is that the odd-number aisles are toward the front and the even-numbered aisles are in the back. Both levels are split about the midway point.

    While it seems that SU107 should be across the aisle from SU207, for example, it is not. SU107 would be across the aisle from SU307. SU207 is halfway back and on the left across the aisle from SU407.
