Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an international standard for adaptive bitrate streaming over HTTP. It enables high-quality streaming of media content by breaking the content into small segments and delivering them over HTTP. DASH is codec-agnostic and supports various container formats, making it versatile for different streaming scenarios. It allows for adaptive bitrate streaming, adjusting the quality of the media stream in real-time based on network conditions and device capabilities, ensuring a smooth viewing experience for users.
