An LED processor is specialized hardware that bridges standard video sources and LED display technology. It's an essential component in most LED wall installations, responsible for signal processing and panel control.
**Core Functions**
**Input Processing** - Accept multiple video sources (HDMI, DisplayPort, SDI, DVI) - Decode compressed streams - Switch between sources seamlessly
**Scaling & Mapping** - Scale content to match LED wall resolution - Map video output to physical LED panel arrangement - Handle non-standard configurations (curved, L-shaped, artistic)
**Color Processing** - Calibration data management - Gamma correction - Color temperature adjustment - Brightness control
**Data Conversion** - Convert video to proprietary LED protocols - Generate data streams for receiving cards - Time the data transmission to receiving cards
**Panel Control** - Power management - Temperature monitoring - Module status reporting - Firmware updates to receiving cards
**LED Processor Brands**
Major manufacturers include: - **Novastar**: Popular for rental and fixed installations - **Colorlight**: Wide range from basic to broadcast grade - **Brompton**: Premium broadcast and virtual production - **Megapixel VR**: Specialized for LED volumes - **ROE Visual**: Integrated with their LED products
Each brand uses proprietary receiving cards and protocols, so the processor must match the LED panels.
**Processor Categories**
**Entry-Level** - Basic scaling and source switching - Single output, limited resolution - Small installations
**Professional** - Multiple inputs and outputs - Advanced color processing - Medium to large installations
**Broadcast/Premium** - Genlock and frame sync - HDR processing - On-camera LED volume support - Mission-critical applications
**Do You Always Need a Processor?**
Some LED configurations accept direct HDMI input to receiving cards, bypassing dedicated processors. This works for: - Simple, single-source installations - When CMS software handles all processing - Cost-sensitive projects with basic needs
SPARC integrates with major LED processor brands, providing unified control regardless of the underlying hardware while adding advanced content management capabilities.
