Professional Broadcast Conversion Engine

The UDC-4K is a compact, rugged Mini-Converter designed for high-end broadcast and production environments. It performs up/down/cross conversion between 4K/UHD and HD formats while maintaining exceptional image fidelity.

Advanced Frame Synchronization

With built-in frame sync capabilities, the device aligns untimed or wild video sources to a reference signal. This ensures perfect timing consistency for multi-camera productions, live events, and broadcast workflows.

High-Quality Signal Processing

Using 12-bit processing and AJA’s polyphase scaling technology, the UDC-4K delivers sharp, artifact-free video conversion. It also includes motion-adaptive deinterlacing for smooth handling of interlaced sources.

Flexible SDI and HDMI Integration

The unit supports both 12G-SDI and HDMI 2.0 inputs and outputs, enabling seamless integration between modern HDMI devices and professional SDI infrastructure.

Distribution and Workflow Efficiency

Beyond conversion, the UDC-4K functions as a 1x4 SDI distribution amplifier, allowing multiple outputs from a single input. This makes it ideal for production trucks, DIT carts, and live event setups.

HDR and Audio Support

HDR workflows are fully supported with proper metadata handling for both SDI and HDMI. It also supports embedded audio processing with sample rate conversion and passthrough modes.
