10 a.m.-11 a.m.
FM Boosters – Opportunities and Challenges
Stan Salek, Senior Engineer, Hammett & Edison
FM boosters have been in regular use for about 20 years. Over that time, many systems have been designed and constructed, with some notable successes, but also a number of disappointments. The key has been to adequately isolate the FM booster signal from that of the main station operating on the same channel in areas of population to be served. This workshop will cover the technical elements needed for successful implementation of FM booster transmitting facilities. Examples of both successes and failures will be presented, along with consideration of performance expectations when FM boosters are designed for IBOC digital radio compatibility.
11 a.m.-12 p.m.
Advances In Remote Control Technology
Tony Peterle, Technical Support Manager, Audemat
Broadcasting is in the midst of a digital revolution. Advanced technology is spreading rapidly throughout the industry, from all-digital television to HD radio to audio over IP to advanced all-digital audio processing and RF test and measurement equipment. One area that has lagged somewhat behind the technological tidal wave is remote facility control, but that is now beginning to change. This workshop presentation explores the new technology being applied to remote facility control.
1:30 p.m.-3:30 p.m.

Next Generation IP-based Audio
Tag Borland, President, Logitek
Network aware professional audio equipment has a poor record of interoperability. Recently available protocols allow multicasting systems, like digital mixers, to automatically find and select the many settings required for network communication to work. Consoles can now find other audio equipment, negotiate communication methods and receive a list of available sources just by turning on the power. Some user groups have started requiring a minimum set of protocols in the networked equipment they buy. Now is the time to start planning for the coming change.
9 a.m.-10 a.m.
High Bandwidth Capacity RF STL/TSL Connectivity
Jim Moody, Senior Consultant, James Moody Associates
Larry Miller, Senior Partner, Schwartz, Woods & Miller
This session will examine and present possible solutions for high bandwidth studio-to-t ransmitter, studio-to-studio and transmitter-to-transmitter connectivity problems. Modern broadcast data connections such as T1, DS3, OC3, and 100baseT Ethernet were not even contemplated when the FCC drafted the rules that govern STL connectivity. Those rules have not evolved with the demands of technology, and broadcasters are now faced with a connectivity dilemma that often dictates looking beyond Part 74 to Part 101 of the FCC rules .
10 a.m.-12 p.m.
HD Radio Measurements Workshop
David Maxson, Managing Partner, Broadcast Signal Lab
HD Radio technology and its implementation require an understanding of measurements techniques not familiar to most radio engineers. Some of what will be covered in this special workshop includes: the HD Radio signal and spectrum, the HD Radio Mask evolution, the current state of the rules, what is PSD and measuring PSD.
2 p.m.-3:30 p.m.
The Embedded Exporter Technical Panel
Moderator: David Layer, Director, Advanced Engineering, NAB
Panelists: Dan Dickey, Vice President, Engineering, Continental Electronics Corp.
Scott Martin, Head of Data Systems, Nautel Limited
Ted Lantz, HD Radio Product Manager, Broadcast Electronics
Tim Anderson, FM/Digital Radio Product Line Manager, Harris Corporation, Broadcast Communications Division
HD Radio transmission equipment has recently advanced to the next level with the unveiling in April of the "Embedded Exporter." HD Radio stations use the Exporter to combine multicast audio channels and advanced data services along with a station's main audio channel into a format suitable for transmission. In this session, the differences between the previous generation of Exporter equipment and the new Embedded Exporter will be explained, with a focus on how this new technology promises enhanced reliability and a greater feature set while at the same time substantially lowering the cost of upgrading to HD Radio technology.

Orban Optimod 8585
Digital surround audio processor
Starting with the technology of Orban's Optimod 6300 two-channel processor for digital transmission media, the 8585 incorporates multichannel processing that reflects the latest psychoacoustic research into loudness perception. The 8585 features Optimod-quality two- and five-band audio processing for surround sound broadcasting, netcasting and mastering. Thanks to versatile compression ratio controls and a mastering-quality look-ahead peak limiter, the 8585 is ideal for mastering audio in broadcast productions. The 8585 is built on Orban's flagship hardware platform. This features a GUI displayed on a quarter-VGA active matrix color LCD, making it easy to do all setup and adjustment from the 8585's front panel. A new third-generation CBS Loudness Controller helps retain audiences by controlling both subjective loudness and annoyance. The multichannel and 2.0 processors can operate with separate audio processing parameters like release times.
The Harris HDE-200 exporter supports the delivery of multiple HD Radio program streams over a single, dedicated IP connection. The development of the new exporter is driven by the need to fortify the E2X (exporter-to-exciter) protocol in the HD Radio transmission chain while minimizing implementation costs for the radio station. The Harris Pacific Design Center has embedded new software code from Ibiquity Digital into a fully functional hardware component with no moving parts, which enables increased reliability. At only 1RU, the HDE-200 offers a drastically reduced footprint with more features and options than its predecessor. The exporter supports TCP over IP transport of the E2X protocol, as well as HD Protocol (HDP). The HDE-200 exporter also includes remote and front-panel metering and monitoring features and an internal GPS module, as well as options for profanity delay, diversity delay and an Arbitron People Meter.
