Virtual canvases mapped to physical LED or LCD displays. Layers: Individual video windows placed onto a screen.
Network drops happen. Design your control driver to monitor socket status. If a connection breaks, the software should attempt background reconnection routines at increasing intervals (exponential backoff) without freezing the entire control UI. 3. Rely on Presets Over Raw Layer Creation
Despite its advantages, the H Series API is not without complexities. NovaStar, like many industrial hardware vendors, prioritizes stability over open standards. The API documentation is typically provided under non-disclosure or only to authorized system integrators. This creates a barrier for smaller developers or open-source projects. novastar h series api
By using the H Series OpenAPI , integrators can automate complex video wall tasks, including layer positioning, preset recalls, and real-time status monitoring, without manually using the web interface or front-panel LCD.
This comprehensive guide explores the multiple API protocols supported by the H Series—including HTTP RESTful API, UDP/RS232 command‑based control, and SNMP monitoring—and provides practical insights into how developers can leverage these interfaces for advanced LED display management.
For applications requiring low latency or operation in secure networks without internet access (e.g., broadcast control rooms), the H Series can be controlled locally via TCP. | Interface | Protocol | Port | Use
Session-based authentication token acquired via a initial POST request containing admin credentials. 3. Core Capabilities Handled via the API
: Bring layers to the front or send them to the back of the visual stack.
In a news studio, LED walls must change inputs automatically based on the show timeline. Design your control driver to monitor socket status
LED sending cards, HDMI multi-viewers, and preview cards.
Seamlessly route any physical input card source (HDMI, DVI, SDI, DP, IP streams) to any configured screen or layer.
