HLS, or HTTP Live Streaming, is a media streaming protocol developed by Apple. It allows users to stream audio and video content over the internet in real-time. HLS works by breaking the media into small segments, which are delivered to the viewer's device as they are needed, ensuring smooth playback even with varying internet speeds. One of the key features of HLS is its ability to adapt to different network conditions. It automatically adjusts the quality of the stream based on the viewer's bandwidth, providing a better user experience. HLS is widely used for live broadcasts, online video services, and mobile applications.
