RTMP, RTSP, SRT, and NDI are all different protocols used for streaming audio and video content over the internet. Each protocol has its own unique features and advantages. In this response, we’ll explore what each protocol is, how it works, and how it’s consumed.

RTMP (Real-Time Messaging Protocol) is a proprietary protocol developed by Adobe. It’s commonly used for streaming video content on platforms like YouTube and Twitch. To use RTMP, you need a video encoder, which captures the audio and video content and compresses it into a digital format. The encoded content is then sent to a streaming server, which distributes the content to the end-users. RTMP has been widely used in the past, but it’s gradually being replaced by more modern protocols like SRT and NDI.

RTSP (Real-Time Streaming Protocol) is an open-source protocol used for streaming audio and video content. It’s commonly used for security cameras and other surveillance systems. To use RTSP, you need an RTSP server, which stores the audio and video content and distributes it to the end-users. RTSP is widely used in the security industry because it supports real-time streaming and is compatible with a wide range of devices.

SRT (Secure Reliable Transport) is an open-source protocol that was designed to address some of the issues with RTMP. SRT is a low-latency protocol that’s optimized for live streaming. It’s designed to work over unreliable networks, which means that it can deliver high-quality audio and video content even in poor network conditions. To use SRT, you need an SRT encoder, which compresses the audio and video content and sends it to an SRT receiver, which decodes the content and distributes it to the end-users.

NDI (Network Device Interface) is a proprietary protocol developed by NewTek. It’s commonly used for streaming video content in the professional production industry. NDI allows you to add multiple video sources to a single network and stream them to multiple devices. To use NDI, you need an NDI-enabled device, such as a camera or a video encoder. The NDI-enabled device sends the audio and video content to an NDI receiver, which decodes the content and distributes it to the end-users.

In terms of consumption, each protocol can be consumed using a variety of devices, such as smartphones, tablets, laptops, and smart TVs. To consume RTMP content, you’ll need a media player that supports the protocol, such as Adobe Flash Player or VLC Media Player. To consume RTSP content, you’ll need an RTSP client, such as IP Camera Viewer or VLC Media Player. To consume SRT content, you’ll need an SRT player, such as Haivision Play or VLC Media Player. To consume NDI content, you’ll need an NDI-enabled device, such as an NDI-enabled camera or an NDI-enabled video encoder.

In conclusion, RTMP, RTSP, SRT, and NDI are all different protocols used for streaming audio and video content over the internet. Each protocol has its own unique features and advantages. The choice of protocol depends on the specific needs of the user, such as the type of content being streamed and the quality of the network connection.
