Adaptive bitrate, also known as ABR, is a video streaming technology that automatically adjusts the quality of a video based on the available network bandwidth. This means that the video will adapt and change its bitrate, or the amount of data being transmitted per second, to ensure a smooth and uninterrupted viewing experience for the user. By constantly monitoring the network conditions, ABR allows for seamless streaming without interruptions or buffering, providing the best possible quality for each individual viewer. This dynamic and intelligent approach to video streaming has become increasingly popular, especially with the rise of online video platforms, as it allows for a personalized and optimized viewing experience for every user.
