Streaming protocols are sets of rules that allow data, such as audio and video, to be transmitted over the internet in real-time. They ensure that the content is delivered smoothly and efficiently, enabling users to watch or listen without significant delays. Common examples of streaming protocols include HTTP Live Streaming (HLS) and Real-Time Messaging Protocol (RTMP). These protocols manage how data packets are sent and received, helping to maintain quality and reduce buffering. They also adapt to varying internet speeds, ensuring a better user experience. By using streaming protocols, services like Netflix and YouTube can deliver content seamlessly to millions of viewers.
