Audiovisual quality estimation for mobile video services

Popis výsledku v původním jazyce

Provisioning of mobile video services is rather challenging since in mobile environments, bandwidth and processing resources are limited. Audiovisual content is present in most multimedia services, however, the user expectation of perceived audiovisual quality differs for speech and non-speech contents. The majority of recently proposed metrics for audiovisual quality estimation assumes only one continuous medium, either audio or video. In order to accurately predict the audiovisual quality of a multi-media system it is necessary to apply a metric that takes simultaneously into account audio as well as video quality. When assessing a multi-modal system, one cannot model it only as a simple combination of mono-modal models, because the pure combinationof audio and video models does not give a robust perceived-quality performance metric. We show the importance taking into account the cross-modal interaction between audio and video modes also code mutual compensation effect. In this cont
