Dynamic Adaptive Streaming over HTTP (DASH) is a technology that allows video content to be delivered over the internet in a way that adapts to the viewer's network conditions. It breaks video files into small segments and encodes them at different quality levels. This enables the streaming service to switch between these segments based on the user's available bandwidth, ensuring smooth playback without interruptions. DASH works by using standard web protocols, making it compatible with various devices and platforms. It enhances the user experience by providing high-quality video while minimizing buffering, even in fluctuating network environments.
