A control-based algorithm for rate adaption in MPEG-DASH

Abstract

Although MPEG-Dynamic Adaptation Streaming over HTTP (MPEG-DASH) eliminates data packet loss, based on the rate adaptation strategy adopted by the user and the network conditions, still playback interruptions may not be avoided. In this paper an algorithm for rate adaption in MPEG-DASH is proposed that employs fuzzy logic to estimate the resolution of the next video segment that each client should obtain from the server. In this way, the buffering time at each client is kept above a target buffering time and thus buffer overflows and unnecessary bit rate fluctuations are avoided. Simulation results showed that the proposed rate adaptation strategy has a beneficial effect on the quality each user perceives.
