Abstract
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.

Unfortunately, to the knowledge of the authors, no citable document describing the VQEG AVHD has been published at the time of writing this book.

Only one video file, present in both the video and audiovisual tests, was corrupted. However, it was crucial for computing the \(Icod_V\) value of several video files with transmission errors and having the same bitrate using the equation \(Itra_V = Qo_V - Icod_V - Q_V\) as shown in Sect. 6.2.2.
