H_1X12G-SDI OUTPUT CARD | Carte de Sortie Single 12G-SDI Novastar H | 4K Broadcast

The Novastar H_1X12G-SDI Output Card is a professional-grade expansion module designed for the Novastar H Series video wall processors. This high-performance card provides a single 12G-SDI output port, enabling the seamless transmission of uncompressed 4K Ultra HD signals via a single BNC coaxial cable. Developed for demanding live environments, it allows users to output processed content for external recording, studio monitoring, or downstream distribution without signal degradation. The card's architecture ensures zero-latency performance, bridging the gap between high-end LED display processing and professional broadcast workflows. With its hot-swappable design, it integrates perfectly into the modular H Series chassis, offering the reliability and scalability required by modern AV integrators and broadcast engineers looking for high-bitrate video delivery.

Broadcast Excellence & Signal Integrity

In the world of professional LED displays, signal quality is paramount. The H_1X12G-SDI Output Card utilizes advanced FPGA processing to ensure that the uncompressed 4K video signal maintains its color accuracy and bit depth. While typical LED installations focus on SMD or GOB pixel pitch and nits, this output card focuses on the back-end integrity of the video pipeline.

High Bandwidth & Technical Reliability

• 12G-SDI Standard: Delivers 12 Gbps bandwidth, supporting 4K resolution at 60Hz over long cable runs where HDMI or DisplayPort might fail due to distance limitations.
• Backward Compatibility: Fully compatible with 6G, 3G, and HD-SDI standards, ensuring interoperability with legacy studio equipment.
• Low Latency Processing: Designed to sync perfectly with the high refresh rates and fast frame multiplexing of modern LED controllers, preventing lip-sync or motion artifacts.
• Hot-Swappable Module: Allows for maintenance and configuration changes without powering down the entire H-Series chassis, a critical feature for high-uptime environments like control rooms and live television.

Versatile Applications for Professional Workflows

The H_1X12G-SDI Output Card is engineered for environments where video signal routing extends beyond the LED wall itself:

• Live Broadcast Studios: Sending the final processed visual mix from the H-Series processor back to the master control room (MCR) for live televised events.
• Event Recording: Capturing high-resolution 4K archival footage of a live event directly from the processor output to professional external recorders.
• Corporate Control Rooms: Distributing visual data to remote viewing stations or secondary monitoring arrays while maintaining the primary feed to the 4K LED command center wall.
• Hybrid Events: Managing the viewing angles and visual consistency of a physical LED stage while simultaneously providing a clean SDI feed for web streaming or satellite uplink.

Technical Implementation & Best Practices

To maximize the performance of your H_1X12G-SDI Output Card, consider these technical guidelines from our engineering team:

• Cabling Requirements: Always use high-quality 75-ohm BNC cables rated for 12G-SDI to prevent signal jitter or packet loss, especially when transmitting 4K content beyond 50 meters.
• Synchronization: Ensure your entire broadcast chain is synced. The H-Series controller supports Genlock, which should be used in conjunction with the SDI output for flicker-free integration with studio cameras.
• Signal Monitoring: Use the SDI output for reference monitoring on professional OLED or high-contrast ratio monitors to verify color grading before the signal reaches the LED tiles.
• Firmware Alignment: Always verify that the firmware version of the output card matches the H-Series chassis master controller to ensure full feature compatibility and stable EDID management.
