Adaptive Bitrate for Video Streaming
Adaptive Bitrate for Video Streaming Adaptive bitrate (ABR) is a smart way to deliver video that changes quality in real time. When a viewer’s connection varies, ABR helps keep playback smooth and enjoyable. It reduces pauses and keeps the image as clear as possible without wasting bandwidth. How ABR works Video is encoded into several quality levels, or representations. Each representation has its own bitrate and resolution. The player downloads short segments and measures how fast data arrives and how full the buffer is. Based on those measurements, the player chooses the next segment from the best-fitting quality ladder. Standards like DASH and HLS provide a map (manifest) of available representations. A typical ladder ...
