Avaliação da qualidade de experiência em transmissão de vídeo com codec H.264 utilizando métricas objetivas de referência completa e sem referência

Abstract

With the increasing availability of digital content across various communication channels, it becomes increasingly essential for providers to ensure the quality of the material they offer, be it text, images, or videos. Quality of Experience (QoE) accomplishes this task by allowing the evaluation of the quality as perceived by the user. In the context of videos, Video Quality Assessment (VQA) provides an estimate of the perceptual quality experienced by viewers through the use of quality assessment metrics. VQA is widely employed to assess the quality of video transmissions, facilitating adaptations and improvements in the systems used. In turn, the H.264 codec plays a significant role in these transmissions, enabling compression and greater efficiency in the systems employed for this purpose. This study aims to evaluate the quality of experience of videos transmitted using the H.264 codec, employing two specific types of metrics: full-reference and no-reference metrics.
