Audiovisual quality estimation device, audiovisual quality estimation method, and program

摘要

An audio-visual quality estimation device includes an audio quality estimator to estimate audio quality for each unit time starting from a playback start time of an audio-visual content, based on a parameter that affects the audio quality among parameters related to the content; a video quality estimator to estimate video quality for each unit time, based on a parameter that affects the video quality among the parameters related to the content; a unit time quality estimator to unify the audio quality and the video quality for each unit time, to estimate audio-visual quality for each unit time; an encoding quality estimator to unify the audio-visual quality for the unit times into one value, to estimate audio-visual encoding quality with respect to encoding degradation, in which temporal quality fluctuation is taken into consideration; and an audio-visual quality estimator to estimate the audio-visual quality perceived by a viewer after an end of the content, based on the audio-visual encoding quality.
