Commands are sent as JSON strings over UDP to port . Each command is enclosed in square brackets and follows a structured format. The general structure is:
Used in specific legacy implementations or for rapid, unacknowledged broadcast status pings, though TCP is highly preferred for command execution due to its error-checking nature.
When using the HTTP REST engine, a preset switch is handled via an explicit HTTP POST request:
def get_device_info(self): resp = self._send_command(0x10) # Parse ASCII part after cmd byte return resp[8:-5].decode(errors="ignore") novastar h series api
For managed service providers (MSPs) and AV-IT administrators, the API serves as a diagnostic tool:
Before writing code against the API, it is essential to understand the hardware topology it governs. The H Series (including H2, H5, H9, and H15) is a modular, slot-based video wall splicing processor. It simultaneously functions as a pure hardware splice processor and an LED engineering controller.
: ID of the window/layer for positioning and source switching . Commands are sent as JSON strings over UDP to port
To start pushing commands to an H2, H5, H9, or H15 processor, developers must provision security keys natively inside the hardware's management layer.
Modern iterations of the H Series firmware feature a RESTful web API, allowing developers to send JSON or XML payloads via standard web requests ( GET , POST , PUT ). 2. Connection Parameters
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 When using the HTTP REST engine, a preset
: Query the status of cards, switch signal sources, and manage resolutions.
The H Series acknowledges each command with a response string containing the original command and an "Ok" acknowledgment appended.
: Unlike simpler controllers, the H Series API provides deep access to the modular nature of the hardware, allowing for specific control over individual sub-cards.
