Video Streaming Protocols: What Are They & How to Choose The Best One

As the demand for video streaming has surged with the advent of mobile devices and smart TVs, the evolution of streaming protocols has become a pivotal aspect of the industry. Initially used for live sports in the '90s, streaming technologies have diversified into various protocols, each offering unique benefits and limitations. Among these, HTTP Live Streaming (HLS) is notable for its widespread compatibility and security, though it suffers from high latency. In contrast, protocols like WebRTC and Secure Reliable Transport (SRT) focus on low latency and security, appealing to real-time applications and privacy-conscious industries. Additionally, legacy protocols like RTMP and RTSP, while foundational, face limitations due to evolving technology standards. The choice of protocol depends on factors such as compatibility, latency, security, and cost, with considerations varying based on specific use cases, such as telehealth or remote education. Ultimately, understanding the capabilities and constraints of each protocol informs the optimal selection for developing robust and efficient video streaming solutions.
