Technology transitions can take many shapes and forms, and some would say we are always in a state of transition. This is true for radio and television broadcasters, and this presentation will focus on tectonic trends that are impacting our business and some specific ways our industry is responding. For radio broadcasters, there is an evolving automotive landscape with great opportunities for engaging listeners in new ways with metadata and connectivity, as well as threats to longstanding services such as AM radio. This talk will explore the digital and legislative realities and options. Television broadcasters in the U.S. have filed a petition with the FCC seeking a full transition to ATSC 3.0 with a defined 5-year timeframe. This talk will lay out what has been requested, how it might be implemented, and the benefits to consumers, plus an innovative new service that can help ensure our economic and national security, the Broadcast Positioning SystemTM (BPSTM).

When something doesn't sound right, what's the first thing you turn to? The audio processor! But what if that's not the issue? Where do you look next? Mike Erickson from Orban Labs will talk about everything you need to consider when you work on or troubleshoot your airchain. With close to 30 years of on-site experience with setting processing, he will explore the good and bad habits broadcasters fall in to when diving into the sound of their stations

Emerging advancements in FM broadcast antenna technology will provide broadband performance while eliminating technical limitations of previous designs such as high wind load, poor circularity, narrow band components, and power limiting geometry. This presentation will propose three key innovations poised to shape the future of FM broadcasting: the Ring 360, RingMaster™, and DCPC antennas. The Ring 360 antenna offers improved circularity and lower wind load over master panel systems while utilizing proven high power antenna bays. The RingMaster™ will provide a compact, broadband-capable solution, maintaining uniform gain and low VSWR compared to standard antenna layouts. Furthermore, the DCPC antenna introduces a new panel concept with increased broadband capability and power handling while maintaining azimuth performance across the band. Collectively, these technologies will redefine FM transmission capabilities, offering scalable, efficient, and high-performance solutions for the broadcasting landscape of tomorrow.

Historically, ATSC has been used as a medium to transmit information to the local communities. The majority of viewers of OTA content can be divided in two categories: The cord-cutters, looking to cut cost but still have access to information, and the local communities, who are looking for content created for them by the local station. Through the use of LLMs (Large Language Models), we can now add additional subtitling tracks by doing speech-to-text translations that would correspond to the needs of the local communities in the area of an ATSC 3.0 station. We will present our tests performed at a local ATSC station, looking into the results along with the (legal and technical) challenges of adding additional subtitling languages.

On the morning after an ice storm, the 300' guyed steel tower tor WRDB in Reedsburg fell to the ground. A herculean effort took place to get the station back on the air, then the time came to investigate a replacement. A fiberglass pole turned out to be the answer.
Karl Lahm, Broadcast Transmission Services
Any tilting of the tower's antenna aperture, whether by guy wire mis-tensioning, tower deterioration, or loading changes, has the potential to affect the coverage and service of stations in the VHF and UHF bands. This presentation will take a detailed look at how any unintended tilting of the antenna aperture of a tower might impact coverage and service. It will begin with a review of the underlying physics, then consider several different real-world scenarios.

As broadcasters transition into the world of High Dynamic Range (HDR), they face a complex landscape of competing standards, legacy infrastructure, and evolving viewer expectations. This presentation explores the multifaceted challenges of working with multiple HDR formats in live and post-production broadcast environments. Key topics include managing simultaneous HDR and SDR deliveries, handling wide color gamuts, and the intricacies of tone mapping and real-time HDR-to-SDR conversion-particularly in live workflows. -- We'll also address compatibility issues with legacy equipment, the visual impact of HDR on graphics and overlays, and emerging solutions such as AI-based upscaling and SDR-to-HDR conversion. Designed for broadcast engineers and managers, this session will offer practical insights into maintaining visual fidelity and operational efficiency in hybrid HDR/SDR pipelines.

ATSC 3.0, marketed as "NEXTGEN TV" to consumers, now reaches 76% of U.S. viewers including those in the Green Bay-Appleton, Wisconsin market; Minneapolis-St. Paul in Minnesota; Champaign-Springfield-Decatur and Chicago markets in Illinois; and Davenport and Des Moines in Iowa.
Broadcasters are sharing transmission facilities, anticipating the eventual end of ATSC 1.0 and full transition to ATSC 3.0 service. While the policy discussions are underway in Washington, TV broadcasters are innovating and adding new features and capabilities to ATSC 3.0 broadcasts. Local stations are adding High Dynamic Range video and Dolby Atmos audio signaling, which greatly enhances the consumer experience (until the eventual arrival of broadcast 4K, after the transition is complete.)
Innovations like "Program Re-Start" and interactive gaming channels are also coming online, as are virtual channels made possible by ATSC 3.0's internet connectivity, allowing local stations to stream weather forecasts, news reports, sports updates, and more. In the wings are future enhancements like specific emergency and information alerting by zip code and new revenue from datacasting, since broadcasting itself is the original wireless platform. A panel of industry experts who serve ATSC - The Broadcast Standards Association -- will address these developments.
Jeff Welton, Nautel
We put transmitters in uninsulated cinderblock buildings at the base of several hundred foot (or taller) lightning rods, at the extreme end of the AC line from the power company. This session will talk about hardening the site - looking at various aspects of infrastructure including grounding, cooling, physical security, and maintaining data integrity. With almost 35 years of visits to hundreds of transmitter sites, Jeff says, "I never say I've seen it all, as that's frequently taken as a challenge." There will be photos of things that could be improved, as well as things being done right, as we look at ways to continually get the best performance from our equipment without breaking the budget.

As the local broadcasters keep rolling out ATSC 3.0 throughout the U.S., many are still bound by the limitations of their production facility (too expensive to upgrade), of their distribution contracts (affiliate station will only receive a feed in 720p60) or even the content itself (original content was captured in HD with 5.1 audio). In this presentation, we will discuss the tools available TODAY for broadcasters to improve the experience of their viewers by using HDR conversions, by leveraging dynamic metadata generation in ST2094, by upmixing the audio from 5.1 to 5.1.4 and, finally, by improving the efficiency of their ATSC 3.0 PLPs with Statistical Multiplexing.

With the new administration in Washington, saying that there has been lots of change in Federal regulation and how it affects broadcasters, would be an understatement. David Oxenford of the Wilkinson Barker Knauer law firm will try to untangle what all of the changes mean for broadcasters on Capitol Hill and at the FCC. We'll talk about reform of the broadcast ownership rules, what's next for the ATSC 3.0 roll-out, what we can expect from Delete Delete Delete, the latest on AM in cars, questions about the FCC's ability to issue fines for violations of its rules, changes in EAS regulation, changes in environmental policies affecting tower construction, and as many other topics as we can fit into this session on the state of broadcast regulation in Washington DC.
