Integrating ATSC M/H into a Broadcast Transmission System 10:50-11:35 a.m.
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.
Mobile DTV Middleware 11:35 a.m.-12:20 p.m.
Speaker: Claude Seyrat, Expway
Mobile DTV hit the market recently in the USA. Japan and Europe had some mixed experience about deploying Mobile DTV. The challenges are clear now - delivery a crystal clear video to handheld devices, with no gaps in the reception. Additionally, broadcasters and manufacturers noticed that a richer experience (i.e. more than a TV) engage the end-users and by consequence, keep the user in front of its screen.
This presentation reviews the capabilities offered to broadcasters to deliver richer Mobile DTV experience, the underlying technology and the key technical challenges to successfully deploy Mobile DTV Service.
LUNCH (included) 12:20-1:30 p.m.
P2 Workflow 1:30-2:15 p.m.
Speaker: Wes Carr, Panasonic
P2 as a solid state acquisition media was so radical when it was introduced in 2003 that most discussion rarely got past the departure from video tape. Now that memory prices have come down and with encoding de-coupled from the media any encoder can be chosen, so solid state memory might undercut the cost of professional tape. As the reluctance to move beyond video tape has evaporated, it is worth looking at the reasons for risking a brake with a tried and true technology in the first place.
The original incentive to pursuing a tapeless media was a desire to store the media file in camera as easily accessed data, just as it lives on the editing platform; so that:
- Editing can be done directly from the media
- Copies of contents can be made significantly faster than real time
- Files need not be trans-coded or even re-encoded, and a complete end-to-end solution can be created with CPU based processing
This presentation will follow the video files all the way through the post production process focusing on areas where speed advantages are most pronounced. Examples in broadcasting and field production will be detailed with specific tools cited and advantages unique to P2 and common all file based acquisition highlighted.
Broadcast Imaging Technology−The State of the Art 2:15-3:00 p.m.
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.
Joint Sessions
Digital Signage – Content and Ad Delivery in the Public Environment 3:15-4:00 p.m.
Speaker: Jim Schoedler, CBNT, JB Schoedler Associates, LLC
Digital signage, also known as "digital out of home" has emerged as a way to deliver highly customized and targeted content in a variety of public and private spaces. Domestic revenue from digital signage is expected to grow by 33% in 2009, despite a very difficult economic environment. One digital signage company alone is responsible for 120,000 screens.
Similarities between digital signage and traditional broadcast technology, such as the means for scheduling, billing, and automating content delivery will be explored. Some interesting implementations by Denver-based Four Winds Interactive that marry digital signage content with traditional and new media technologies will also be reviewed.
Tower Catastrophes: Lessons Learned 4:00-4:45 p.m.
Speaker: James Heard, Electronics Research, Inc.
Five structural failures involved towers that were supporting PBS and or NPR stations, and four of those structural failures resulted in all or part of the tower collapsing. This session includes a brief review of the investigation into the failures, as well as a discussion on lessons learned in investigating these failures.

Content Management and Control of HD Radio™ Networks
via HD Protocol Sidebands 10:50-11:35 a.m.
Speaker: Timothy Anderson, CSRE/DRB, CBNT, Harris Corporation
With the advent of the third generation HD Radio™ architecture, including the Embedded Exporter platform and v.4x software, a significant paradigm shift has taken place within the HD Radio broadcast system. In order to meet the needs of today’s diverse broadcast system topologies and enhance the utility of HD Radio, this new architecture defines both a Content Management Framework and a common communications protocol between the various HD Radio components for command and control.
HD Protocol or HDP is now the standard protocol used by the HD Radio Broadcast System and will support content creation and distribution, command and control of the entire HD Radio system from local, centralized and remote locations as well as providing options to improve robustness and security.
In this presentation, the form and structure of the Content Management Framework and the HDP protocol is reviewed. We will discuss the current implementations that are available today for system wide command and control as well as pending future developments and network architecture that will allow both centralized and distributed content creation, management and insertion.
HD Radio™ Power Increase 11:35 a.m.-12:20 p.m.
Speaker: Hal Kneller, CPBE, DRB, Nautel
A digital power level increase has been proposed to the FCC and the industry awaits action. We will discuss how this managed power increase works, and if approved, 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.
LUNCH (included) 12:20-1:30 p.m.
A Case Study of Inter-modulation Products 1:30-2:15 p.m.
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.
Considerations for Digital Radio Antenna Design 2:15-3:00 p.m.
Speaker: Matt Leland, Dielectric Communications, SPX Corp.
With the forthcoming potential increase in power for HDRadio, 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.
