MPEG-DASH, short for Dynamic Adaptive Streaming over HTTP, is a popular streaming protocol that enables efficient delivery of multimedia content over the internet. It provides a standardized approach for adaptive streaming, allowing seamless playback across various devices and network conditions.

With MPEG-DASH, video and audio content is divided into small chunks, each encoded at different quality levels. These chunks are then delivered over HTTP, allowing the client to dynamically switch between different quality levels based on available bandwidth and device capabilities.

This protocol utilizes Media Presentation Description (MPD) files, which contain metadata about the media segments, enabling the client to request and play the appropriate chunks. This adaptive streaming technique ensures a smooth and uninterrupted viewing experience for users.

MPEG-DASH supports a wide range of media formats, including popular codecs like H.264, VP9, and AAC. It also provides support for features like subtitles, multiple audio tracks, and DRM protection.

Overall, MPEG-DASH revolutionizes the streaming landscape by offering a flexible and efficient solution for delivering high-quality multimedia content over HTTP, catering to the diverse needs of modern consumers.
