High Bi-directional Transfer

Enables high-bandwidth two-way conversion between 4K HDMI and full NDI. It encodes 4Kp60 HDMI to full NDI or decodes 4K full NDI to HDMI. With HDMI in/out, it loops the encoded feed for monitoring or outputs the decoded video via HDMI.

Key Features

Dual Power Options

Support both Power over Ethernet (PoE) and traditional USB-C power supply. This dual capability empowers users with flexibility and convenience, allowing users to choose the most suitable power source based on their specific requirements.

High Bidirectional Transfer

Enables high-bandwidth two-way conversion between 4K HDMI and full NDI. It encodes 4Kp60 HDMI to full NDI or decodes 4K full NDI to HDMI. With HDMI in/out, it loops the encoded feed for monitoring or outputs the decoded video via HDMI.

Next-Level NDI Conversion

Featuring professional-grade Full NDI encoding technology, it supports encoding and decoding of video up to 4Kp60 resolution. Full YCbCr 4:2:2 chroma-subsampled video streaming is supported, meeting the demands of high-end production.

Intuitive Status Display

Features a LCD display showing real-time tally lights, network status, bitrate and key parameters. The intuitive interface with buttons enables quick adjustments even in fast-paced production environments.

Flexible Audio Mixing

Supports HDMI embedded audio and 3.5mm analog line input and output. Whether it's HDMI-embedded audio or external sources like professional mixers, or media players, our flexible configuration.
