## What is SRT? Secure Reliable Transport (SRT) is an open-source video streaming protocol designed to deliver high-quality, low-latency video over unpredictable networks, such as the public internet. Developed to address the challenges of real-time video delivery, SRT combines robust security, reliability, and efficiency, making it a preferred choice for broadcasting, live streaming, and remote video contribution. Secure Reliable Transport (SRT) was developed by Haivision, a leading provider of video streaming solutions.

It uses advanced error correction techniques to maintain stream integrity. - **Low Latency**: Optimized for real-time applications, SRT minimizes delays, enabling near-instantaneous video delivery for interactive and live scenarios. - **Robust Security**: With 128/256-bit AES encryption, SRT protects content from unauthorized access, ensuring secure end-to-end transmission. - **Firewall-Friendly**: SRT’s handshake mechanism allows outbound connections without requiring open inbound ports, simplifying network configuration while maintaining security. - **Reliable Performance**: SRT’s Automatic Repeat Request (ARQ) recovers lost packets, ensuring consistent video delivery even on congested or unreliable networks. - **Open-Source Collaboration**: Freely available, SRT fosters widespread adoption and interoperability across hardware and software solutions, with a growing community driving continuous innovation. ### Why SRT Stands Out Unlike traditional streaming protocols, SRT is built to handle the unpredictable nature of IP networks. Its ability to adapt to fluctuating conditions ensures smooth, high-quality video delivery, making it ideal for applications like live sports, news broadcasting, and remote production. The protocol’s open-source nature eliminates licensing costs, encouraging broad adoption and seamless integration across diverse platforms. ## Industry Recognition SRT’s innovative approach to video transport has earned it prestigious recognition, including an Emmy® Award for Technology and Engineering from the National Academy of Television Arts and Sciences (NATAS) in 2018, highlighting its impact on live video contribution and distribution. This accolade was awarded to Haivision, SRT’s developer, for pioneering a reliable transmission method for live TV links, as noted in their official announcements and industry reports (Haivision, 2018; Sports Video Group, 2022). **REF:** [Haivision Wins Technology and Engineering Emmy® Award](https://www.haivision.com/about/press-releases/haivision-wins-emmy/) ## Use Cases for SRT SRT is versatile and supports a wide range of applications, including: - **Live Event Streaming**: Deliver broadcast-quality video for concerts, sports, and conferences. - **Remote Production**: Enable real-time collaboration between remote crews and central studios. - **Cloud Workflows**: Securely transmit video to and from cloud-based platforms for processing or distribution. - **Edge-to-Core Connectivity**: Stream video from remote locations, such as branch offices or field cameras, to central hubs. ## Using SRT with ORBNET Streaming Engine The ORBNET Streaming Engine is a powerful platform that fully leverages SRT’s capabilities to provide flexible, high-performance video streaming solutions. It supports both ingestion and distribution of SRT streams, enabling seamless video workflows with or without Milestone XProtect integration. ### Key Benefits of ORBNET Streaming Engine with SRT - **SRT Ingestion and Distribution**: The Streaming Engine can ingest SRT feeds from diverse sources, such as IP cameras, drones, or mobile devices, and stream out in SRT to remote sites, cloud platforms, or other systems. This ensures secure, low-latency video delivery over unpredictable networks. - **Milestone XProtect Integration**: Stream live or playback video from XProtect cameras using SRT for secure, low-latency delivery to remote sites, cloud platforms, or third-party systems. The Streaming Engine supports easy configuration and resilient streaming, even in high-availability setups. - **Standalone Mode**: Without XProtect, the Streaming Engine can ingest SRT feeds and redistribute them to other platforms or VMS solutions, making it ideal for edge deployments, pop-up setups, or cloud-based workflows. - **Protocol Flexibility**: In addition to SRT, the Streaming Engine supports RTSP, RTMP, WebRTC, HLS, and MJPEG, allowing you to mix and match protocols for ingestion and distribution. - **High Availability**: With intelligent load balancing and auto-reconnect features, the Streaming Engine ensures uninterrupted streaming, even during network disruptions or server failovers. - **Developer-Friendly**: A robust REST API and Swagger UI simplify integration with analytics, monitoring systems, or custom workflows. ### Example Scenarios - **Branch-to-HQ Streaming**: Ingest SRT streams from remote office cameras and distribute them securely to a central monitoring hub over the public internet using SRT output. - **Cloud-Based Analytics**: Ingest SRT feeds from edge devices and stream them to cloud platforms for real-time processing, with SRT output ensuring reliable delivery. - **Live Broadcasting**: Ingest SRT streams from field cameras and redistribute them via RTMP to platforms like YouTube or Twitch, leveraging SRT’s low-latency and secure transport. ## Get Started with ORBNET Streaming Engine The **ORBNET Streaming Engine** makes it easy to harness the power of `SRT` for both ingesting and streaming video.
