the client dynamically selects the appropriate quality level for the next segment based on real-time network conditions.This adaptive approach allows DASH to seamlessly switch between different quality levels, preventing buffering issues in situations of varying bandwidth availability.DASH relies on the Media Presentation Description (MPD) file, which contains metadata about the available representations and their corresponding URLs.The client uses this information to make informed decisions about the next segment to request.The combination of adaptive bitrate streaming and the MPD file ensures that DASH adapts to network conditions in a granular and responsive manner, enhancing the overall quality of the streaming experience.HTTP Live Streaming (HLS) employs a similar adaptive streaming approach to dynamically adapt to changing network conditions.HLS divides the video content into small segments, typically a few seconds in duration, and encodes them at different quality levels.The client device continuously monitors network conditions and dynamically adjusts the quality of video segments during playback.HLS uses the M3U8 playlist file to manage the sequence and quality of these segments.The client periodically downloads the playlist, allowing it to make informed decisions about the appropriate quality level for the upcoming segments based on real-time network conditions.One of the notable aspects of HLS adaptation is its ability to handle disruptions in network conditions gracefully.When network bandwidth decreases, HLS can smoothly switch to
