Abstract: A quality-aware rate adaptation algorithm is described to optimize the quality of experience (QoE) for a DASH client. Requesting media at a bitrate higher than the available network bandwidth can lead to re-buffering events that disrupt user experience, while requesting media at lower bitrates may lead to sub-optimum streaming quality. The quality-aware algorithm tries to optimize the QoE of a DASH client by maintaining a better trade-off between buffer levels and quality fluctuations.
