The user perceived quality or Quality of Experience (QoE) is of significant importance to multimedia service providers because of its relevance for efficient management of provided services. However, due to its subjective nature, QoE is difficult to estimate. Subjective methods are costly and impractical, while objective methods do not correlate precisely with the subjective perception. In addition to the challenges in estimating QoE, further challenges are presented in determining the means of managing the QoE in today's complex and varied multimedia distribution systems. As a result of the high number of components and parameters that affect the perceived quality, from content creation to delivery and presentation, the QoE aware management in these highly versatile environments becomes increasingly difficult.
