Seamlessly switch an input source within an active layer.
The NovaStar H Series breaks the traditional mold of LED controllers by utilizing a modular, card-based design that combines video processing and display control into a single chassis. It is specifically engineered to handle fine-pitch LED displays, supporting massive pixel capacities.

Bring layers to the front or send them to the back.
Saved configurations of layers, sources, and window positions. novastar h series api
The is a network-based protocol designed for intelligent, automated control of NovaStar H-series splicers. Using a RESTful HTTP/HTTPS approach (commonly utilizing POST requests), it allows external control software (like Crestron, Q-SYS, or custom applications) to interact directly with the device. Key Benefits of the API:
The H Series handles dozens of layers depending on the chassis size. The API allows you to: Dynamically change layer coordinates (X, Y positions). Scale layers in real time (Width, Height). Adjust Z-order (layer priority/stacking). Configure Picture-in-Picture (PIP) and transparency. Device Status Monitoring & Environmental Feedback
Specifies the action (e.g., brightness adjustment, preset load). Data Length: Indicates how many bytes of parameters follow.
The API is exposed via the (LAN) or the dedicated Gigabit Ethernet port running in control mode. Ensure your firmware is updated to at least version 1.7.0, as earlier versions had limited API endpoints. Seamlessly switch an input source within an active layer

are you using (e.g., Crestron, Python, C#)?
Every screen or screen group on the H Series supports multiple layers. Through the API, developers can programmatically manipulate layers in real-time: Using a RESTful HTTP/HTTPS approach (commonly utilizing POST
Programmatically toggle live mode on or off depending on whether you want changes to broadcast instantly or stage them first. Why Use the NovaStar H Series API?
The H-Series API functions primarily over standard network protocols, allowing developers to send commands from any network-connected device. 1. Communication Protocol
