10Gigabit Cable for Audio and Video Applications
Speaker: Steve Lampen, CBRE, Belden
The hottest new thing in data is 10gig, 10GbaseT, and it will be sweeping into audio, video and broadcast applications soon. This presentation shows what it is, how it works, and why previous cable designs don’t work. Connectors, patch panels, and patch cords are also critical and are included.
IP Addressing and Computer Interfacing
Advanced IP / Facilities Management

How Cable Works
Speaker: Steve Lampen, CBRE, Belden
Using lots of pictures and stories, here’s a primer on wire and cable, including multiconductor, twisted pairs and coaxial cable. Find out where they came from, why they were invented, and how they work. Included is an overview of analog and digital signals, frequency and wavelength, resistance, capacitance, inductance, and the result of those three parameters, impedance. There’s also a refresher on unbalanced and balanced lines, return loss, and skin effect.
Antennas 101
Speaker: Bob Surette, Shively Labs
While there has been a host of technology changes over the years when it comes to FM RF transmission systems, there is a need for a good understanding of basic filter and antenna theory starting with isotropic ‘perfect’ sources. This presentation will take the audience through how energy is radiated from a single source and how multiple sources can be connected together to form a simple antenna array.
Using examples, Surette will show how familiar parameters, such as beam tilt and null-fill, are realized within a practical array by varying the amplitudes and phases of the feeds to each source. Expanding the discussion to the differences between isotropic sources and real antennas, he will explain how various methods commonly used to reduce downward radiation are implemented within the practical antenna array.

Integrating ATSC Mobile DTV into a Broadcast Transmission System
Speaker: Richard Schwartz, Axcera
Now that the ATSC M/H (mobile/handheld) standard has been approved, broadcasters are understandably enthusiastic about the new business opportunities that it will provide. In order to take full advantage of this important new technology, it is essential to have a clear understanding of the options and choices for converting transmission facilities to incorporate M/H. This presentation will seek to provide that understanding, covering such areas as exciter conversion, multiplexing, single frequency networks (SFNs), power level and coverage considerations for mobile vs. fixed reception, and all aspects of the transmission chain that are affected. While it is anticipated that most broadcasters will initially convert their existing single transmitter for dual service (fixed and M/H), the different coverage considerations for mobility and reception by a portable receiver may soon encourage the development of a network with multiple transmitters. The presentation will address this migration, and concepts to implement initially, while planning ahead for a multi-transmitter network.
KREX – The Real World of Disaster Recover
Speaker: Craig Beardsley, CPBE, Harris BCD, HPS
For most engineers, the Disaster Recovery Plan is a file on their hard drive that is a rarely updated and a sketchy plan on what should be done if the station is destroyed. Find out what real world lessons in disaster planning were learned when the CBS and Fox affiliate in Grand Junction, Colorado burned completely to the ground and the Super Bowl was just two weeks away.
Broadcast Imaging Technology−The State of the Art
Speaker: Tony Delp, Grass Valley
CCD imagers have been the dominant technology in cameras for all broadcast applications for more than 20 years now. During that time span CCDs have evolved to a high level of performance. This presentation will focus on the core imaging technology that Grass Valley has developed for HD acquisition over the past decade, with an overview of the unique features available in the latest CCD imagers such as the HD-DPM+ technology.
Explore why CMOS imagers are now viable for professional applications and the current status of this imager technology in the broadcast and entertainment market. There will also be a discussion around the design of the XENSIUM™ 2/3 inch full−raster HDTV CMOS imager, its implementation in both the LDK 3000 system camera and the Infinity file-based camcorder and the performance parameters that have been achieved. In addition, the CMOS imager technology holds much promise for the future, including extended dynamic range modes and higher speed signal readout. Finally, learn why the 2/3” CCD or CMOS sensor (and not a smaller version) is the appropriate size−technically and aesthetically−for the current and next generation of broadcast camera.
ATSC Mobile DTV Signaling, Announcements, and Non-Real Time Widgets
Speaker: Mark Rushton, Roundbox
Starting with a brief review of the core, standard ATSC-M/H building blocks, this presentation adds-on ATSC A/153 supplements. It reveals Service and Content Discovery mechanisms that energize with Mobile DTV Widgets, subscription, Ads and PPV revenue. The results are a premium Mobile DTV based service for connected devices.

Providing Media-Rich Content Using Digital Radio
Speaker: Timothy Anderson, CSRE/DRB, CBNT, Harris Corporation
Since its inception, digital radio broadcast technology has held the promise of media-rich visual user experiences and multimedia data transport. Digital radio data services have the capability to deliver new revenue streams to broadcasters. By enhancing digital radio broadcasts with synchronized visual content and leveraging data and file transfer capabilities, it is possible to present media-rich content to the user while creating ubiquitous low cost transport mediums for advertising and information on personal devices as well as public displays through electronic signage. Multimedia enhanced radio services can provide direct revenue streams or may simply enhance the broadcaster’s brand. The one-to-many nature, low cost per data unit, localized footprint, and ubiquitous penetration of radio places radio broadcasting in an enviable position as a data service provider. Digital media over radio creates a new, exciting frontier for creativity and innovation. The author will discuss the principals, systems, protocols and applications required to present graphical content through enhanced broadcast transmission and receiver platforms.
HD Radio™ Power Increase
Speaker: Hal Kneller, CPBE, AMD, DRB, CBNT, Nautel
A digital power level increase was approved by the FCC in January and broadcast engineers now have many questions on how to deal with this. This presentation will review how this managed power increase works and what the options are. In addition, stations who have already implemented HD Radio™ broadcasting may contemplate a digital power increase. This will be discussed from a transmitter and implementation standpoint.
Considerations for Digital Radio Antenna Design
Speaker: Matt Leland, Dielectric Communications, SPX Corp.
With the increase in power for
HD Radio™, station engineers are faced with making the decision of which implementation method will suit their particular station best in terms of both performance and economics. This session details the benefits of the various antenna solutions, including having the ability to utilize existing transmitters while achieving the increase digital ERP desired and significantly lower electricity consumption and operational costs on an ongoing basis.
A Case Study of Inter-modulation Products
Speaker: Bob Surette, Shively Labs
In February of 2009 a new station went on the air in Peterborough, Ontario by sharing an antenna system. The station achieved this by installing a branched combiner system so that the existing station and this new station would not generate inter-modulation products (Spurs). Immediately after the new station starting transmitting the local neighbors complained about interference on their radios. The DOC (Canadian FCC) made measurements and verified that the new station was not in compliance and was forced off the air. By demonstrating the proper methodology in how to measure inter-modulation products, it was shown that the inter-modulation products being heard around the transmitter site were not generated by the transmitters. Instead the inter-modulation products being heard were due to receiver over load forcing the DOC to allow the station to go back on the air. This presentation describes how a transmitter combiner system must be designed to guarantee that Spurs are not generated, what was done to prove that the combiner did meet the spur specification and how test equipment has to be calibrated so that correct measurements can be made.
