1. What Is the NovaStar H2 Video Processor?
It is a video wall splicer — a device that takes multiple video inputs, processes them, and sends the combined output to an LED screen. Think of it as the “brain” of a large LED display system: it combines video sources and controls how they appear on screen. It belongs to NovaStar’s H Series, which also includes larger models like the H5 and H9.

What makes this processor different from a basic LED sending card is its modular design. You choose which input cards and output cards to install based on your project’s needs. The NovaStar H2 can work as both a video processor and a video controller, or as a pure splicing processor when paired with external sending devices.
The H2 is the central hub between your video sources (cameras, computers, media players) and your LED screen. It decides how many sources show up at once, where they appear, and how smoothly they transition.

3. Key Features of the NovaStar H2

01. Modular and Hot-Swappable Design
All input and output cards on the NovaStar H2 are plug-in modules. You can add, remove, or swap cards without powering down the device. This means you can start with a basic setup and expand later, or replace a faulty card without interrupting a live event.
02. Multi-Layer Display
A single NovaStar H2 card supports up to 16 single-link (2K) layers, 8 dual-link layers, 4 4K layers, or 2 8K layers. Layers can cross output connectors, and cross-connector output does not reduce the available layer count.
What this means in practice: You can display multiple video sources at the same time — cameras, presentations, advertisements, and monitoring feeds — without needing additional processors. For a control room, this lets you watch security cameras, data dashboards, and live TV feeds on one screen simultaneously.
03. Multi-Screen Management
You can control multiple LED screens from one NovaStar H2, each with its own resolution. Preset groups let you save layouts across several screens and load them with one click — useful for venues with multiple displays that need coordinated content changes.
04. BKG and OSD Support
Background images (BKG) do not consume layer resources and support resolutions up to 64K pixels wide. On-screen display (OSD) options include static text, scrolling text, time, weather, and image overlays — all configurable per screen.
05. Web-Based Control
The NovaStar H2 uses a browser-based interface (B/S architecture). No software installation is needed — you control everything from a web browser on Windows, Mac, iOS, Android, or Linux. Multi-user collaboration is supported, meaning your video engineer and LED technician can work on the same project simultaneously from different computers. The interface also allows firmware updates directly through the browser.
06. Backup and Reliability
The NovaStar H2 supports three levels of backup:
| Backup Type | How It Works |
|---|---|
| Device backup | A secondary NovaStar H2 takes over automatically if the primary fails |
| Card backup | Sending cards configured in primary-backup pairs for seamless failover |
| Input backup | If one video source drops, the backup source takes over without blackout |
This makes the NovaStar H2 suitable for 24/7 operation in control rooms and live broadcast environments where downtime is not acceptable.
07. Additional Processing Features
Beyond basic splicing, the NovaStar H2 includes 3D display support (when paired with NovaStar’s EMT200 3D emitter), low-latency mode (as low as 1 frame from input to receiving card), input source cropping and renaming, channel logo overlays, and reverse control of source PCs from the web interface.
4. NovaStar H2 Applications

The NovaStar H2 fits a wide range of LED display projects, including rental LED screens and stadium LED screens:
| Application | Why the H2 Works Well |
|---|---|
| Broadcast studios | 10-bit processing, Genlock for frame sync, 3,840Hz output avoids camera flicker |
| Control rooms | Multi-layer display, IP camera decoding (up to 512 sources), multi-screen management |
| Live events & staging | Hot-swappable cards, preset switching with fade effects, compact 2U touring size |

8. How to Set Up the NovaStar H2
If you are setting up a NovaStar H2 for the first time, here is a simplified overview of the workflow:
- Install your input and output cards into the chassis slots (hot-swappable, no tools needed)
- Connect video sources to the input card connectors (HDMI, DP, SDI, etc.)
- Connect the output card to your LED sending cards or directly to LED cabinets via Ethernet/fiber
- Connect the control PC to the H2’s Ethernet port on the control card
- Log in via web browser using the device IP address (default: 192.168.0.10)
- Configure the LED screen in NovaLCT or SmartLCT — set cabinet size, verify the LED screen resolution, then define the connection topology and receiving card layout
- Create your first preset — arrange layers, assign input sources, and save for one-click recall
For detailed step-by-step instructions, refer to the NovaStar H Series user manual or ask your supplier for setup support.
9. Is the NovaStar H2 Worth Buying?
For most mid-size LED projects, yes. Here is a quick breakdown.
Buy the H2 if you:
- Run 3 or more video sources on one screen
- Manage multiple LED displays from one system
- Need backup reliability (live events, broadcast, 24/7 control rooms)
- Expect your setup to grow over time
Skip the H2 if you:
- Only send 1-2 sources to a single screen
- Have a simple fixed sign — a basic sending card is enough
Why the H2 delivers good value: It packs the same core processing engine as NovaStar’s larger H5 and H9 models into a compact 2U chassis. You buy only the input/output cards you need today and add more later — no need to replace the whole unit. For rental crews, hot-swappable cards mean a failed module is swapped in seconds without powering down.
If you are building a mid-size LED project with room to grow, the H2 is a one-time investment that won’t hold you back. If your needs are simple and static, save the budget.
