H_4X3G SDI INPUT CARD | Carte d'Entrée Quadruple 3G-SDI Novastar H | Full HD Broadcast

The Novastar H_4X3G SDI INPUT CARD is a professional-grade expansion module designed specifically for the H Series modular video wall processors (H2, H5, H9, and H15). Featuring four independent 3G-SDI ports, this card allows for the seamless integration of up to four uncompressed Full HD (1080p @60Hz) video sources. Developed for the demanding broadcast and live event industry, it ensures rock-solid signal stability over long cable runs without the latency issues common in HDMI conversions.

As a key component of the Pixelight inventory, this card supports Quad-Link 4K configurations, enabling users to combine four SDI inputs into a single UHD source. Its hot-swappable design guarantees maximum uptime, making it an indispensable tool for technical directors requiring reliable, high-bandwidth video ingestion for large-scale LED displays where image integrity and synchronization are paramount.

Professional Broadcast Integration for H-Series Processors

In the world of high-end LED displays, signal integrity is the foundation of visual quality. The H_4X3G SDI INPUT CARD leverages the 3G-SDI standard to provide a robust interface that outperforms consumer-grade connections. Unlike hardware using high-compression codecs, this card manages raw video data, ensuring that the contrast ratio and color depth of your SMD or GOB LED panels are fully preserved from source to pixel.

Ultra-Low Latency and Synchronization

When driving large LED video walls, frame synchronization is critical to prevent tearing. This module supports sub-millisecond processing latency, aligning perfectly with the H-Series' internal throughput. By utilizing the 3G-SDI infrastructure, users benefit from professional Genlock capabilities. This is vital when the refresh rate of the LED wall (often exceeding 3840Hz) must be perfectly phased with camera shutter speeds to avoid flickering or scan lines during live broadcasts.

Advanced Connectivity

• Four Independent 3G-SDI BNC Ports: Reliable locking connectors prevent accidental disconnection.
• Long Distance Transmission: Maintains 1080p signal purity over coaxial cables far exceeding HDMI limits.
• Quad-Link 4K Support: Aggregates bandwidth to handle Ultra-HD content distribution.

Versatile Deployment Scenarios

The H_4X3G SDI INPUT CARD is designed for environments where failure is not an option and signal quality is the priority.

• Television Studios & Broadcast: Perfectly integrates multi-camera feeds into the LED backdrop with zero perceptible lag, ensuring the viewing angle and color reproduction remain consistent for the viewing audience.
• Live Concerts & Touring: High-durability BNC connections are ideal for the rigors of touring, connecting long-range FOH (Front of House) signals to the stage LED screens.
• Control Rooms: Allows for the simultaneous monitoring of four high-definition feeds on a single large-scale LED surface, essential for security or mission control.
• Corporate Events: Enables seamless switching between professional video switchers and the Novastar H-series modular chassis for high-impact presentations.

Technical Implementation & Optimization

To achieve the best performance from your Novastar H_4X3G SDI card, our Pixelight technical team recommends several best practices:

• Cable Quality: Always use high-quality 75-ohm coaxial cables (RG6 or equivalent) to ensure maximum brightness and color accuracy without signal dropouts over long distances.
• Redundancy: For mission-critical events, utilize the multiple inputs to set up primary and backup signal paths within the Novastar H-series software interface.
• Maintenance: Because this card is hot-swappable, it can be replaced while the processor is powered; however, always ensure the locking BNC mechanism is fully engaged to prevent intermittent signal loss.
• Resolution Matching: Align the input resolution (1920x1080) with the native pixel pitch mapping of your LED display to avoid unnecessary scaling artifacts, maintaining a 1:1 pixel mapping for maximum clarity.
