Kiloview N50 12G-SDI to NDI Bi-Directional Converter

N50 12G-SDI All-in-One Encoder/Decoder
Kiloview N50 is a 12G-SDI bi-directional video converter designed for IP-based video workflows. It employs efficient AVC, HEVC, and NDI codecs for both encoding and decoding, supporting a broad array of streaming protocols such as NDI High Bandwidth, NDI HX2/HX3, SRT, RTMP, HLS, TS-UDP, RTP, and RTSP. Built for professional broadcast, it delivers exceptional 4:2:2 10-bit HDR image quality. For remote and cross-network workflows, the N50 also supports seamless internet transmission through the NDI Bridge Utility. Fully compatible with the latest NDI 6.2, it offers improved performance and workflow efficiency. Additional features such as PoE, Tally, PTZ control, KIS Pro intercom, and 3.5mm audio embedding further complete its professional IP production capabilities.

Bi-directional Encoding & Decoding Converter
The N50 is a versatile converter that integrates both encoding and decoding functionalities in one compact unit.

• In encoding mode, the N50 easily converts a 4K 12G-SDI video into NDI High Bandwidth, NDI HX2/HX3, SRT or RTMP video streams.
• In decoding mode, it automatically detects and adapts to incoming NDI High Bandwidth, NDI HX2/HX3, SRT, or RTMP streams. A loop-out also allows monitoring on a display or projector for easy video signal check in real time.
• With its dual-mode flexibility, the N50 is ideal for a wide range of professional AV workflows

4K HDR Tier-1 Image Quality
Kiloview N50 delivers 4:2:2 10-bit HDR 4K video, providing exceptional color accuracy, rich tonal range, and lifelike, vivid visuals. This high-end image quality is ideal for professional applications such as broadcasting, medical imaging, and content creation.

Comprehensive Protocol Support for Seamless Format Conversion
The N50 supports all major IP transmission protocols—NDI High Bandwidth, NDI HX2, NDI HX3, SRT, RTMP, RTSP, HLS, UDP, and RTP, allowing effortless conversion and interoperability between different streaming formats. Whether you’re pushing a high-quality NDI feed to the network or pulling an SRT or RTMP stream for local output, the N50 bridges protocols and devices, ensuring smooth operation in any hybrid workflow.

Broadcast-Grade Interlaced and Progressive Signal Handling
The N50 fully supports 1080i60 interlaced signals throughout the entire processing chain:

• 1080i50/i60 in → 1080i50/i60 out
• 1080i50/i60 in → 1080p50/p60 out
• This flexibility ensures smooth operation in studios working with both interlaced and progressive formats.
• N50 supports injection of SEI timecode and synchronization of multi-camera feeds to embedded system time or source device time.​
• *N50 supports processing of 1080i50/i60 signals, with the capability for native 1080i50/i60 output. This feature is available when the device utilizes ​ NDI HB or H.265 codec, but is ​not supported under the H.264 codec.

Flexible Audio Options, Just the Way You Need
The N50 offers comprehensive audio integration to suit a wide range of production scenarios:

• SDI audio de-embedding for direct mixer connection
• Real-time analog audio embedding via 3.5mm input
• Up to 8-channel synchronized audio decoding transmission

Large-sized Color LCD Screen with Tally

• Clear status display with intuitive navigation: Real-time display of network connection, operating mode, and device information keeps you fully informed, while the intuitive scroll wheel allows quick navigation and precise adjustment of key settings.
• Tally Indicators: Front panel LCD, rear Tally LEDs, and external Tally support provide clear red/green indicators for PGM (program) and PVW (preview) status.

Redundant Power Supply wtih PoE
The N50 features dual Gigabit Ethernet ports, one supporting PoE for combined power and network over a single cable. The dual network port design provides primary-backup redundancy. If the primary port fails, the backup port ensures service continuity. Additionally, these ports support bonding function, allowing different network to share data transmission—ensuring uninterrupted video streaming.​

Fast and Easy PTZ Control
The N50 supports controlling external PTZ camera via USB to serial (RS-232/RS-485/RS-422) or over network protocols such as VISCA, VISCA over IP, and Pelco. It enables precise adjustment of pan, tilt, and zoom, making it ideal for studios, conferences, live events, and other professional scenarios with easy operation and fast response.

Flexible Storage Options
The N50 offers three flexible recording options:

• Local TF card storage
• USB external drives
• Network-attached storage (NAS)
• Recording format, mode, and file splitting can be customized for both local (TF card/USB) and NAS storage, with support for MOV and MP4 formats.
• *Note: Some USB drives may not be supported if their power requirements exceed the N60’s output capacity.

Real-Time Voice Communication for Efficient On-Site Coordination
The N50 supports USB-connected microphones and headsets when integrated with Kiloview’s KIS intercom system to enable instant voice communication and seamless remote collaboration——ideal for live directing, remote production, and mobile reporting.

Centralized Management with Kilolink Server Pro
The N50 seamlessly connects to the KiloLink Server Pro once registered, enabling centralized remote management with real-time monitoring of device status, including connectivity, video preview, bandwidth, and IP address—all in one interface for streamlined oversight.

Visual Input Loss Alerts for Instant Issue Identification
When a video source or network stream is interrupted, the system automatically displays a preset “No Video” screen or a custom PNG image (1920×1080 or 1280×720), instead of defaulting to a black or blue screen. This maintains a clean, professional output while helping users quickly pinpoint input-side issues—minimizing downtime and avoiding confusion.

Compact Design with Easy Camera Mounting
The N50 features a compact design and comes with a standard threaded cold shoe mount, making it easy to attach directly to a camera.
