and USB extension, making them versatile for integrated AV environments.
ensures that AV content can be distributed across indoor and outdoor spaces, including the VIP suite, terrace, and training rooms, with real-time control and monitoring available through touch panels (Figure 5). Intuitive touch panels help manage control of each operator's workstation, enabling real-time switching and monitoring of complex signal flow with ease. Each touch panel interface is integrated with a centralized control processor, allowing for synchronized management of AV sources and destinations. Broadcast feeds are carried in serial digital interface (SDI) formats, including 12G-SDI, a SMPTE standard widely adopted in professional video production environments. This ensures compatibility with high-resolution camera systems and mobile production units. AV POWER MANAGEMENT To ensure long-term reliability and uninterrupted performance, the AV infrastructure integrates redundant signal paths, standardized rack configurations, and comprehensive thermal and power management strategies. Thermal control
is achieved through active ventilation systems, including rack-mounted fans and vented enclosures, with airflow modeling used during design to prevent equipment hotspots and maintain optimal operating conditions. Power integrity is maintained via rack-mounted uninterruptible power supplies (UPS) and power distribution units (PDU) equipped with surge suppression. Critical components within the signal routing backbone feature redundant, hot-swappable power modules, allowing for maintenance or failure recovery without system downtime or service calls. Surge protection is deployed across both indoor and outdoor zones to guard against voltage spikes caused by environmental factors such as heat, humidity, and lightning. While high foot traffic does not directly contribute to electrical surges, it does increase the risk of physical strain on exposed cabling and connectors, which is mitigated through secure cable management and ruggedized infrastructure design. ADVANCED VIDEOWALL AND SIGNAL MANAGEMENT An expansive DVLED display was installed to function as both the stadium’s scoreboard and its primary event presentation screen. The AV system leverages the stadium’s distributed matrix switching architecture to deliver real-time content to the videowall and other
endpoints. This setup enables operators to dynamically route live camera feeds, replays, and sponsor media with minimal latency and consistent image quality. Incoming video signals are resized to match the videowall’s native resolution, ensuring clear, high- resolution delivery regardless of source format. Signals from multiple sources are time-aligned to prevent tearing or jitter, which is critical during live broadcasts and multi-camera productions. In addition, the system automatically adapts incoming signals to the required output format, supporting a wide range of resolutions and frame rates. The scoreboard is connected via high-bandwidth optical fiber and copper tie lines that carry video, audio, control, and data signals throughout the stadium. Tie lines are permanent cabling pathways installed during construction to enable fast, reliable signal transport between key AV zones, such as the field, press box, and equipment rooms. At each tie line endpoint, broadcast panels are installed. Broadcast panels are wall or rack-mounted interface boxes that consolidate multiple AV connections. These allow external production crews to quickly connect their equipment to the stadium’s AV infrastructure. The panels were pre- terminated, meaning both the cabling and connector terminations were completed and tested prior
SEAMLESS INTEGRATION To support live event production, the AV system was designed with dedicated infrastructure for seamless integration with broadcast trucks. A set of transmitters located in a broadcast bunker feeds the fourth-floor matrix switcher, which then distributes content to lower floors via the interconnected switchers (Figure 4). This setup enables broadcast teams to inject live video feeds into the stadium’s AV system and route them to any display or digital signage endpoint. Operators can select between broadcast and videowall feeds using touch panel interfaces located throughout the facility, including classrooms, the box office, and the press box. Optical fiber tie lines and auxiliary input/output connections provide flexible, high-bandwidth connectivity for mobile production units, ensuring smooth integration with the stadium’s AV backbone. Digital signage and classroom displays are also connected to the matrix switchers, allowing videowall feeds, broadcast streams, and instructional media to be routed dynamically. The system’s flexibility
