Everlasting Summer Posted January 29 Share Posted January 29 "RTMP" (Real-Time Messaging Protocol), "SRT" (Secure Reliable Transport), and "NDI" (Network Device Interface) are three different protocols used for streaming and broadcasting video over a network. Each has its unique features, advantages, and use cases: RTMP (Real-Time Messaging Protocol): Purpose: Initially developed by Macromedia, RTMP is widely used for streaming audio, video, and data over the Internet, typically from a media server to a flash player. Key Features: Low latency. Adaptive bitrate streaming, which adjusts the video quality according to the viewer's bandwidth. Usage: Commonly used for live streaming on platforms like YouTube, Facebook Live, and Twitch. Limitations: Being an older protocol, it lacks some modern features like error correction. Many platforms are moving away from RTMP in favor of newer protocols. SRT (Secure Reliable Transport): Purpose: Developed by Haivision, SRT is designed for secure and reliable transport of high-quality, low-latency video across the public Internet. Key Features: High performance in poor network conditions. Supports encryption for secure transmission. Error recovery and jitter control, ideal for unstable networks. Usage: Used in broadcasting where quality and security are paramount, especially over unpredictable networks. Advantages Over RTMP: Offers better security, error correction, and is more suited for unstable network conditions. NDI (Network Device Interface): Purpose: Developed by NewTek, NDI is used for sharing video sources over a local network in real-time. Key Features: High-quality video with low latency. Allows multiple video systems to communicate over a local area network. Usage: Widely used in broadcast studios and live event production, where multiple video sources need to be shared and managed over a network. Advantages: Flexibility in connecting multiple devices and sources. High-quality video suitable for professional production environments. Limitations: Primarily designed for use within a local network and not over the public Internet. So: RTMP is a more traditional protocol best suited for live streaming to large audiences over the Internet. SRT excels in secure and reliable delivery of high-quality video over potentially unstable networks. NDI is ideal for high-quality, low-latency video sharing within a local network, especially in professional production environments. Link to comment Share on other sites More sharing options...
