: The API eliminates the need for multiple disparate controllers, allowing a single command to affect complex configurations across various input and output cards. Core Capabilities and Operational Efficiency novastar h series api
The NovaStar H Series represents a paradigm shift in the professional audiovisual (AV) industry, serving as the first all-in-one video splicing processor and controller specifically designed for fine-pitch LED applications. While the hardware provides raw power—supporting up to 520 million pixels and 16 layers per output card—it is the that truly unlocks its potential for large-scale system integration. This API enables third-party developers to move beyond the standard web-based interface, facilitating automated, highly customized control systems essential for modern control rooms, broadcast studios, and live events. A Foundation of Modular Control | Field | Size (Bytes) | Description |
The NovaStar H Series (H2, H5, H9) are high-performance all-in-one LED display controllers widely used in live events, command centers, and fixed installations. This paper details the API capabilities of the H Series, covering TCP/IP-based command protocols, HTTP REST endpoints for third-party control, and integration with show control systems (Crestron, Extron, Q-SYS). Practical examples include input switching, layer management, preset recall, and device monitoring. | | Command Code | 2 bytes |
