This report outlines the technical framework for the NovaStar H Series OpenAPI

, designed for third-party control of video wall splicers (H2, H5, H9, and H15). 1. Core API Overview

The H Series OpenAPI allows external systems to perform real-time adjustments to video processing and display settings. It primarily utilizes requests to send JSON-formatted commands. Default Credentials

: HTTP (OpenAPI) and UDP (used by some third-party modules). Version Reference

: Latest documentation as of early 2026 includes updated error codes and device status polling. 2. Essential API Categories Key endpoints for automating video wall operations: Typical Operations System/Device

Read device detailed information, IP settings, and system initialization status. Screen Control

Set screen brightness, adjust Gamma, and display Screen IDs. Input/Output

Configure resolutions, timing, cropping, and read detailed signal info.

Add/delete layers, modify Z-order, and set layer basic information (position/size). Unlocking the Power of Novastar H Series API:

Create, delete, and load presets (the most common automation task). Manage background images and IP camera source lists. 3. Implementation Requirements

To use the API, you must first enable and configure a project within the device's web console: Enable OpenAPI : Navigate to Open API Management in the H Series web interface. Generate Secret Key : Create a new project to generate a Project ID Secret Key for authenticated requests. Command Structure : Usually follows the format

The NovaStar H Series video wall splicers utilize an OpenAPI based on the HTTP protocol with JSON data formatting for third-party control . This API allows developers to manage layers, presets, and input sources remotely . API Access & Setup

To begin using the API, you must first enable and configure the project through the device's web interface .

Login: Access the web console using the device's IP address (default is 192.168.0.10) and credentials (default: admin/admin) . Enable API: Navigate to Settings > OpenAPI Management .

Create Project: Click Add to create a new project. The system will automatically generate a pId (Project ID) and a secretKey required for authentication in your requests . Communication Protocol Method: POST . Format: JSON-based instruction set .

Encapsulation: Commands are typically enclosed in brackets (e.g., [ "cmd": "...", ... ]) .

Port: The default control port is 6000 for UDP-based command packets, though standard API interactions often use the HTTP interface . Key API Command Parameters

When constructing commands, you will frequently reference these specific IDs found in the H Series Splicers Control Protocol : inputId: Unique ID for the signal source channel . screenId: The specific screen being controlled .

layerId: ID of the window/layer for positioning and source switching .

presetId: Used to recall or overwrite saved layout configurations . Common Operations

Third-party developers can perform various tasks via the H Series OpenAPI : Device Control : The API allows developers to

Presets: Read currently played presets, edit preset groups, or overwrite existing ones .

Layers: Adjust position (X, Y) and size (Width, Height) coordinates for precise layout control .

IPC Sources: Manage IP Camera source lists, including adding, deleting, or renaming channels .

Monitoring: Query device status such as temperature, voltage, and connection health .

For detailed command syntax and specific JSON structures, refer to the NovaStar H Series OpenAPI Instructions or the official H Series User Manual .

If you tell me the specific programming language you're using (e.g., Python, C#, JavaScript) or the control system (e.g., Crestron, Q-SYS), I can provide a code snippet for a basic command like switching a preset. H Series Video Wall Splicers User Manual - NovaStar

The NovaStar H Series API: Bridging Proprietary Hardware and Custom Integration

In the rapidly evolving landscape of LED display technology, the ability to interface directly with hardware has shifted from a luxury to a necessity. As display systems grow more complex—spanning stadiums, broadcast studios, and fine-pitch corporate lobbies—the demand for automation, remote monitoring, and third-party integration has surged. NovaStar, a dominant force in LED control systems, addresses this need through the H Series API. Designed for their flagship H Series receiving cards, this API represents a critical evolution: moving from manual, front-panel configuration to software-defined, automated display management.

7. Limitations & Alternatives

No native video feedback via API (use external capture).
Layer z-order not directly settable (use preset recall as workaround).
Alternative: Use NovaStar’s V-Can automation via UI macro recording (not recommended for critical systems).
