Abstract

Aiming at the existing problems of the dynamic adaptive bit-rate selection algorithm, an improved dynamic adaptive bit-rate selection algorithm based on DASH technology is proposed. To solve the optimal allocation of resources in the process of streaming media transmission, the algorithm reduces the number of video re-buffering by dynamically adjusting the buffer’s key value, and improves the broadcasting quality of video by effectively reducing the startup time of video playback and switching frequency between videos with different quality. Simulation results show that the proposed algorithm can better adjust the playback bit-rate and increase the quality and stability of video playback under various bandwidth conditions. It can optimal configuration of DASH service and provide users with a good video playback experience.
