Audiovisual Quality Model

This chapter presents the parametric audiovisual quality model developed in this work. The model estimates the perceived audiovisual quality of Standard Definition (SD) and High Definition (HD1080, HD720) audiovisual streams. The same model is used for all SD and HD video formats. It is developed for application to network planning and quality monitoring, and is suitable for encrypted audiovisual streams. It covers mainly audio and video compression artifacts and impairments due to packet loss. Addressed audiovisual contents are typical TV programs such as sports and movies.
