Preface
This book presents a new approach to examine the perceived quality of audiovisual sequences. Standard subjective quality tests record a subjective quality judgment in order to draw conclusions about the user’s quality perception. It remains unclear how exactly this judgment is formed within the test participant, and what might be the physiologically-based implications when exposed to lower quality media. Therefore, electroencephalography (EEG) is used to address these issues within this work. First, a series of studies using short (audio)visual recordings of a human head uttering a syllable were conducted. Here, short-term reactions within the EEG are examined, using event-related potentials (ERP). It was shown that when perceiving short video snippets, a neural reaction is observed. The recorded ERP was different for different intensities of stimulus degradation. Subsequently, it was examined how quality degradations affect the mental state of participants w
