With aging gear and a major video board upgrade looming, the time was right for the Mariners to rethink how their control room fuels the fan experience. They weren’t looking for a standard update. Their vision was bold: create a modern production hub that empowers their crew, amplifies storytelling, and sets the stage for the next era of in-venue entertainment.
This wasn’t maintenance. It was momentum, turning technical limitations into creative opportunity. To make it happen, they called in a trusted technology partner who knows the ballpark almost as well as they do — Diversified.
“This wasn’t just about replacing aging equipment. It was about rethinking how we tell the Mariners story and create unforgettable moments for our fans.”
Rather than tearing everything down at once, the Mariners took a strategic, phased approach. Phase one focused on critical infrastructure — replacing the aging video router and laying the groundwork for the control room’s IP-based backbone. Phase two brought the full vision to life: a completely reimagined control room built on the SMPTE ST 2110 standard, ready for HDR, and packed with cutting-edge gear designed to meet the creative ambitions of their production team.
Driving the Seattle Mariners’ newly updated production control room is a state-of-the-art SMPTE ST 2110-based solution built on Imagine Communications’ Selenio Network Processor (SNP) and Magellan Control System. The widely deployed combination handles a mix of UHD, HD, and HDR content, ensuring that all audio and video feeds — whether from cameras capturing live game action or filming the crowd — are delivered in pristine quality to the right locations. Additionally, NMOS-based orchestration ensures efficient control and management of video network-connected devices, guaranteeing that each piece of equipment operates in harmony.
Imagine’s SNP is the industry’s first fully network-attached media processing platform, offering a unique architecture that is easily reconfigured with different functionality by simply enabling the appropriate features. At T-Mobile Park, the SNPs serve as HDR up/down/cross converters and SDI/IP gateways, as well as highly scalable, low-latency production multiviewers, which enable content from different video formats and HDR systems to be integrated into a consistent display environment.
The Magellan Control System delivers SDI/IP routing control, orchestration, and real-time monitoring and analytics through user-friendly, highly customizable interfaces and panels. Equally compatible with SDI, SMPTE ST 2110, VSF TR-08 JPEG XS, and MPEG-2 TS signals, Magellan Control integrates readily with other systems, enabling new production environments to be easily brought online. For the control room operators at T-Mobile Park, the system’s intuitive work surface and advanced control environment makes the IP technology underneath feel and act just like a traditional SDI router.

We invested in powerful new gear and reimagined the layout of the control room. It’s not just about better tech — it’s about giving our crew the tools to work more efficiently, communicate, and execute at a higher level every night.”
The new control room unlocked a new level of creative potential for the Mariners’ production team – which they will continue to realize over many years to come. With expanded camera coverage, modern infrastructure, and streamlined workflows, they can now deliver more dynamic, engaging content that puts fans at the center of the experience. From sharper visuals to new fan-focused features, the technology elevates every moment—whether it’s showcasing live activations within the facility’s entertainment district or creating captivating content worthy of a national broadcast.
The shift to an IP-based, HDR-ready environment positions the organization for whatever comes next, giving the team flexibility to experiment and grow without limitations. And for the crew behind the scenes, a better-designed space means smoother shows, improved collaboration, and room to push the envelope. This isn’t just a new control room—it’s a launchpad for next-level storytelling and a future-ready foundation for one of the most electric game-day experiences in Major League Baseball.
“Being at the ballpark is more than just watching baseball. There’s nothing like 40,000 plus fans rising as one. It’s feeling the roar, the unity, the heartbeat of the game. This control room brings that energy to life — turning game day into a lifelong memory.”
