Abstract

A method and an apparatus for estimating a quality of an audio-video signal includes calculating audio and video quality factors from audio and video technical characteristics. An audio-video quality factors interaction is computed from an interaction between the audio and video quality factors. At least one of an audio quality, a video quality and an audio-visual quality is computed using the audio and video quality factors and the audio-video quality factors interaction.
