The NovaStar H20 represents the pinnacle of video wall splicing technology, tailored for fine-pitch LED screens and large-scale installations. It is part of NovaStar’s H-Series lineup, which is renowned for delivering exceptional image quality and advanced processing capabilities.

Unlike basic controllers, the H20 is engineered for professional environments where precision, flexibility, and reliability are paramount. Whether you’re managing multi-screen configurations, handling high-definition inputs, or orchestrating intricate layer-based content management, the H20 is built to meet these demands seamlessly.

As a modular system, the H20 integrates both video processing and control functionalities, making it an ideal choice for projects requiring centralized management and long-term stability.

The NovaStar H20 distinguishes itself through its innovative design, robust hardware architecture, and versatile feature set. Below are some key aspects that make it a leader in the field:

2.1 Modular and Plug-In Design

The H20 adopts a modular structure, allowing users to configure input and output cards based on their specific needs. This flexibility ensures that the system can be tailored to fit any project size or complexity.

• Input Cards: Support a wide range of connectors, including HDMI, DVI, DP, VGA, CVBS, SDI, and IP.
• Output Cards:Offer options like 4K sending cards, fiber outputs, and HDBaseT ports for ultra-long-distance transmission.
• Hot-Swappable:Input and output cards can be replaced without shutting down the system, minimizing downtime.

2.2 Advanced Video Processing

The H20 supports 10-bit video source input and HDR10/HLG processing, ensuring unparalleled image clarity and color accuracy. With support for resolutions up to 8K, it delivers stunning visuals even in the most demanding scenarios.

2.3 Multi-Screen and Multi-Layer Management

One of the standout features of the H20 is its ability to manage multiple screens and layers simultaneously. Each screen can have its own resolution, and the system supports up to 320 layers (16 per card), enabling highly dynamic content arrangements.

2.4 Web-Based Control

The H20 uses a B/S architecture, allowing cross-platform access from Windows, Mac, iOS, Android, and Linux devices. This web-based interface simplifies setup and collaboration, with real-time monitoring and firmware updates available directly via the browser.

2.5 Redundancy and Stability

Equipped with redundant power supplies and backup mechanisms between devices and ports, the H20 ensures uninterrupted operation. Its self-test functionality and automatic monitoring further enhance reliability.

In a typical LED video wall installation, the NovaStar H20 serves as the central hub, connecting video sources, processing signals, and transmitting data to LED sending cards.

3.1 Signal Input and Processing

The H20 accepts video signals from various sources—computers, media players, cameras, or broadcast equipment—through its input cards. These signals undergo advanced processing, such as scaling, cropping, and layer composition, before being routed to the appropriate outputs.

Key features include:

• Auto Decryption: Automatically decrypts HDCP-encrypted sources.
• Frame Synchronization:Ensures all output connectors display images synchronously, eliminating tearing or lag.
• Low Latency: Reduces latency to as low as one frame, critical for live events and real-time applications.

3.2 Layer-Based Content Management

The H20 excels in managing layered content, allowing multiple video sources to coexist within the same output space. For example:

• A background layer might display static imagery.
• Overlay layers could show dynamic content like scrolling text or logos.

This approach simplifies content adjustments without requiring physical changes to signal connections.

3.3 Output and Transmission

After processing, the H20 sends the finalized video data to LED sending cards through its output architecture. The system supports three types of 4K sending cards:

• H_20xRJ45 Sending Card:Loads up to 13 million pixels.
• H_16xRJ45+2xFiber Sending Card:Provides backup between Ethernet and fiber ports.
• H_4xFiber Sending Card:Supports independent, copy, and backup modes.

These options cater to diverse installation requirements, from short-range to ultra-long-distance transmission.

3.4 Centralized Operation

With its centralized control capabilities, the H20 streamlines system management. Users can adjust screen layouts, manage content layers, and monitor inputs/outputs—all from a single interface.

The versatility and performance of the NovaStar H20 make it suitable for a wide range of industries and applications:

4.1 Energy and Power

In control rooms and command centers, the H20 manages complex visualizations of energy grids, weather patterns, and operational metrics.

4.2 Judicial Departments and Prisons

For surveillance and monitoring purposes, the H20 provides clear, synchronized feeds across multiple screens.

4.3 Military Command

Its low-latency processing and multi-layer capabilities are crucial for tactical operations and decision-making.

4.4 Exhibitions and Presentations

At trade shows and conferences, the H20 powers immersive LED walls with seamless transitions and vibrant visuals.

4.5 Stage Rental and Events

From concerts to corporate events, the H20 ensures reliable performance and stunning image quality under pressure.

The NovaStar H20 is positioned in the premium segment of video wall splicers. Prices typically start around USD 6,000, depending on configuration and additional accessories. While this may seem steep compared to entry-level controllers, the H20’s advanced features and scalability justify the investment for professional-grade installations.
