ABMA+: Lightweight and Efficient Algorithm for HTTP Adaptive Streaming.

Currently exploited adaptive video streaming algorithms mainly focus on maximizing video representation while they usually not assess the risk of video freezing and not care about the influence of video representation switching. We propose a new Adaptation & Buffer Management Algorithm, called ABMA+, which selects video representation based on the predicted probability of video freezing. The algorithm continuously estimates segment download time characteristics and use the pre-computed playout buffer map to select the maximum video representation which guarantee smooth content playout. Our algorithm, thanks to the buffer map, avoids heavy online computation so it could be widely deployed on different terminals. The performed simulation and trial experiments confirm the efficiency of our approach.
