Quality of Experience Paradigm in Multimedia Services: Application to OTT Video Streaming and VoIP Services introduces the concept of 'Quality of Experience', presenting all parameters which directly or indirectly influence the user s satisfaction within two well-used Internet services, multimedia OTT streaming and voice over IP. The authors investigate user's QoE, following three directions, methodologies for subjective QoE assessment of video services, approaches to regulate a rate adaptive streaming video in accordance with the user's QoE, and VoIP QoE-based power efficient resource allocation methods for cellular technology. The emerging fast growth of multimedia services has created new challenges for network service providers in order to guarantee the best user's Quality of Experience (QoE) in diverse networks with distinctive access technologies. In fact, it becomes difficult for a network service provider to guarantee a high user satisfaction, as high network Quality of Service (QoS) does not guarantee this aspect.
