Abstract
This book addressed key research questions related to audiovisual quality perception for interactive videotelephony applications. Evaluating the experienced quality of videotelephony and more generally of interactive video communication systems requires to design ecologically valid contexts of assessment to reflect realistic usage cases. In the case of video calls, conversational tests constitute an adequate assessment situation as they reflect the natural human process of exchanging information between two conversing partners in a mediated way. In this book, the characteristics of audiovisual conversational quality perception for videotelephony services are evaluated in the framework of the ITU-T parametric model G.1070.
