NDI in Liberty Court Recorder: What It Is and Why It Matters?

Last Spring (April 2024), Liberty Court Recorder introduced support for Network Device Interface (NDI) video sources, expanding the options for high-quality video capture in courtrooms. This spring, we’re taking it a step further with NDI broadcasting capabilities, allowing real-time video distribution across networks.

What is NDI and Why Does It Matter?
NDI is a high-performance video-over-IP protocol developed by Vizrt NDI AB. Originally designed for the broadcast industry, NDI has become a widely adopted standard in professional AV environments due to its ability to deliver low-latency, high-quality video over standard Ethernet networks. Its efficiency and flexibility make it an ideal solution for government, legal, and courtroom applications where reliable, real-time video transmission is essential.

NDI vs. RTSP: Understanding the Differences
Both NDI and RTSP (Real-Time Streaming Protocol) are used to transmit video over networks, but they serve different purposes:

• RTSP Streams
  Commonly used for security cameras and surveillance, RTSP requires point-to-point connections between devices, often introducing higher latency. While effective for monitoring, RTSP is not optimized for low-latency, multi-source recording in real-time environments like courtrooms.
• NDI Streams
  Designed for professional AV applications, NDI enables multiple video sources to be shared seamlessly across a network with near-zero latency. It eliminates the need for dedicated video cabling, reducing infrastructure costs while improving video quality, flexibility, and ease of setup.

Why NDI is Becoming the AV Standard
NDI adoption is increasing across professional AV environments due to its:

• Broadcast-Quality Video
  Ensures clear, high-definition recordings without excessive compression.
• Efficient Network Usage
  Unlike RTSP, which often requires dedicated network configurations, NDI operates over existing IP networks without overloading bandwidth.
• Proven Reliability
  Originally developed for live television broadcasts, NDI offers stable, high-performance video transmission—critical for court recording.
• Scalability
  NDI allows for easy expansion of multi-camera setups without the need for additional hardware or complex cabling.

NDI Support in Liberty Court Recorder
Liberty Court Recorder now offers two levels of NDI integration:

• Standard NDI
  Included in the base recorder program, ideal for smaller-scale video setups.
• Advanced NDI
  Designed for high-resolution, multi-source video environments, ensuring smooth performance and enhanced processing capabilities.

Getting Started with NDI in Liberty Court Recorder

1. Download the NDI engine from the Liberty Recording website.
2. Extract the files and place them in the same folder as your Recorder program.
3. Define your NDI video sources in the ‘Video’ tab under Liberty options.
4. Start recording with fully integrated NDI-enabled devices.

Future-Proofing Government AV Infrastructure
As courts and government agencies transition to modern AV solutions, NDI offers a scalable, cost-effective, and high-quality alternative to legacy streaming protocols. Its ability to handle multiple video sources efficiently makes it a compelling choice for courtroom recordings, virtual hearings, and council meetings.

By integrating NDI with Liberty Court Recorder, IT professionals can deliver seamless video capture, reduced infrastructure complexity, and greater efficiency in government AV workflows.
