Preface
Modern IP-based networks and video communication solutions (VVoIP) offer the opportunity to easily communicate and share moments with family and friends on the one hand and to remotely work with colleagues by replacing physical meetings on the other hand. Although, the advantages of videotelephony over speech-only telephony seem to be obvious, videotelephony has not quite replaced it notably due to both human and technical factors. Poor-delivered technical quality or a low level of social presence constitute such limitations. Therefore, there is a need to develop a comprehensive model to evaluate and instrumentally predict the audiovisual quality as perceived by the user. Particularly, quality aspects are crucial when it comes to mobile usage with limited bandwidth, signal processing capabilities, or rendering technologies. The current technological limitations in terms of signal compression and network transmission lead to various types of ar
