TLDR
A video bitrate adaptation strategy, deployed in overloaded channel of an access network, is proposed and evaluated, which takes decisions about bitrate switching based on QoE related parameters to minimize playback stalls.Abstract:
Several reports on Internet traffic have shown that HTTP adaptive streaming is fundamental for multimedia content transport and delivery. Despite the large body of work in this area, running streaming applications on overload channels demands effective delivery strategies. In this work, a video bitrate adaptation strategy, deployed in overloaded channel of an access network, is proposed and evaluated. This strategy takes decisions about bitrate switching based on QoE related parameters to minimize playback stalls. In the experiments conducted to evaluate the effectiveness of the proposed strategy, the average video bitrate, instability and fairness are measured over all of the played video sessions.read more
