Der Rückblick zum TEWI-Kolloquium von Savvas Argyropoulos, Telekom Innovation Labs, TU Berlin am 23.11.2012 beinhaltet die Folien:
Abstract: The proliferation of IPTV services during the last years has necessitated the development of objective video quality assessment methods. It has become evident that network parameters which define the Quality of Service (Qos) are not sufficient to estimate the service quality perceived by the user, typically referred to as Quality of Experience (QoE). This talk will present an objective no-reference bitstream and hybrid video quality assessment method and provide details on the algorithms which are employed to evaluate different types of degradations, such as compression artefacts, packet loss impairments, playback freezing and re-buffering .
