## 4K HDMI NDI Encoding/Decoding Card All the NDI Power You Need for Stunning 4K Video
4K HDMI NDI Encoding/Decoding Card
Kiloview **RN-40** is a bi-directional HDMI to NDI encoding/decoding card designed for Kiloview rackmount chassis RU01/RU03.
It supports 4Kp60 HDMI encoding to NDI High Bandwidth with loop-through for local monitoring, or decoding NDI High Bandwidth streams back to HDMI output.
Ideal for 4K IP-based production workflows, RN-40 ensures high-quality, low-latency video transmission and supports seamless switching between encoding and decoding modes.

## Bi-directional 4K HDMI ↔ NDI High Bandwidth Conversion The RN-40 supports encoding HDMI signals (up to 4Kp60) into NDI High Bandwidth streams or decoding NDI streams back to HDMI. With HDMI loop-through, it enables real-time monitoring and efficient signal routing, ideal for IP-based 4K/HD workflows.
## True 4K, Broadcast-Ready The RN-40 delivers 4Kp60 video encoding/decoding with YCbCr 4:2:2 color sampling, ensuring vibrant color and consistent image quality for high-end productions.
## Flexible Audio Options for 4K Streaming • HDMI audio embedding & de-embedding for mixer connection
• Real-time analog audio embedding via 3.5mm input
• 2-channel synced audio with up to 16-channel mapping
## Stable NDI Source Switching for HD Production In decoding mode, pre-set up to 9 NDI sources and switch instantly via the web interface—no blackouts, stutters, or signal loss. Transition timing can be adjusted to fit your live production.
## Precision PTZ Control for 4K Workflows Advanced PTZ management supporting USB serial (RS-232/485/422) and IP-based protocols, delivering precise control over 4K camera movements. Designed to enhance complex UHD live productions and remote directing workflows.
