to installation. This ensured consistent performance, reduced the risk of field errors, and minimized the onsite labor during deployment. Now, third-party crews may send live video feeds to the scoreboard, receive audio feeds, and control cameras without rewiring or complex routing. In the press box, broadcast panels are typically used by portable production kits or smaller field units, such as camera operators and announcers. Larger mobile production trailers connect at field-level panels, where vehicle access and infrastructure are designed to support full-scale broadcast operations. AV SYSTEM CONTROL AND AUTOMATION AV system control centralizes the monitoring and streamlined operation of AV functions throughout the stadium. The system includes control processors carefully stationed throughout each equipment room, press box, classroom, and training facility. These processors communicate over IP networks and are programmed to respond to user inputs, scheduled triggers, and conditional system states. They are used for routing signals, adjusting audio levels, and switching between displays, ensuring all AV systems are synchronized and adaptable to a variety of different event types. Thoughtful consideration went into planning control logic distribution among several control
processors situated in different areas of the stadium complex to ensure there were no single points of failure that would adversely affect smooth and reliable operation. The design team also implemented network segmentation and traffic prioritization to prevent congestion and ensure reliable performance. This implementation isolates control signals using VLANs and quality of service (QoS) policies to avoid packet loss and latency issues that could disrupt AV operations (Figures 6 and 7). AV resource management software provides IT and AV administrators with a consolidated control
dashboard. Accessible via web browser on designated workstations, this interface allows staff to monitor the status of matrix switchers, amplifiers, displays, and control processors in real time. It also supports device alerts, log aggregation, and performance analytics, enabling proactive maintenance and rapid fault resolution. Remote access capabilities allow technicians to perform system resets, firmware updates, and configuration changes without needing to be physically present, streamlining operations and reducing downtime. RESULTS The renovation of Mt. SAC’s Hilmer Lodge Stadium delivered a fully integrated AV and data infrastructure built on the college’s unified network backbone. The system supports live broadcast production, instructional AV, and immersive fan experiences. The system enables seamless content routing and real-time signal processing across the stadium, ensuring synchronized delivery to the videowall and other displays. The stadium now operates as a fully digital environment, supporting simultaneous AV over IP and baseband signal workflows across interconnected spaces. The integration of AV over IP is aligned with the ANSI/BICSI 007-2024 standard for Intelligent Buildings, which provides guidelines for AV and IT system implementation over a unified infrastructure. AV system monitoring and control are centralized
through a network-based dashboard interface, allowing authorized staff to manage AV operations, monitor device status, and trigger automation routines. BROADER IMPACT The operational model established at Hilmer Lodge Stadium has inspired the design and implementation of AV systems across other major facilities on campus, including the 145,000-square-foot aquatics and gym complex. The new facility integrates 90 AV over IP endpoints across multiple venues, including the main gym, multipurpose gym, diving pool, and meeting spaces. The complex mirrors Hilmer Lodge’s stadium in its design approach. Content is routed to any combination of displays, videowalls, and digital signage systems, with resolution scaling and audio synchronization handled automatically at each endpoint.
