Adaptive Bitrate Streaming is a technology that allows video and audio content to be delivered over the internet in a way that adjusts the quality based on the user's connection speed. This means that if a viewer has a fast internet connection, they will receive a high-quality stream, while those with slower connections will get a lower-quality version. This helps to minimize buffering and interruptions during playback. The process works by encoding the same content at multiple bitrates and resolutions. When a user starts watching, the streaming service automatically selects the best version for their current network conditions. As the connection changes, the quality can adapt in real-time, ensuring a smoother viewing experience.
