Implementação de uma métrica de qualidade de vídeo em dispositivos móveis que consideram degradações no domínio do tempo e espaço

Abstract

The traffic volume of video streaming service has increased considerably in recent years due to the success of content distributors such as YouTube and Netflix. However, limitations in network capacity and instability, impact the user Quality of Experience (QoE). In this work, a quality assessment model for video streaming service is proposed and implemented in mobile devices. The proposed model considers the spatial degradations of the video frames and the temporal interruptions. The experimental results show the impact of degradation factors on the user's QoE; emphasizing that the proposed model achieved a high correlation with subjective tests. Furthermore, the implementation on the mobile device has a low consumption in both processing capacity and energy.
