Player baré: um sistema web para execução de vídeos com subsídio à avaliação subjetiva da qualidade percebida realizadas por clientes de prestadoras de serviços de streaming de vídeos

Abstract

Due to the significant advancements in telecommunications and internet technologies, various video streaming service providers such as Netflix, Net, Amazon Prime Video, Globo Player, among others, can make their content available to customers for viewing through video players. In this context, regulatory agencies aim to ensure that customers can truly enjoy the services offered by these providers. The National Telecommunications Agency (Anatel), the regulatory agency in Brazil, requires service providers to conduct customer satisfaction surveys, typically conducted through phone calls or emails. Among the various questions, the one related to the perceived quality of the videos watched by customers, known as Quality-of-Experience (QoE), is generally the most relevant. It is worth noting, however, that there are limitations to the current method used to measure QoE, as surveys are conducted long after the videos have been watched by customers and are carried out by companies hired by the service providers themselves.To address these limitations, this work proposes a WEB application, called Player Baré, which not only plays videos from providers but also allows the recording of subjective evaluations by customers about the perceived visual quality, either during or after watching the videos. Player Baré also sends these evaluations to both service providers and regulatory agencies. The Agile Scrum methodology was adopted as a construction guideline for Player Baré, and various systems analysis and development technologies were used, such as Visual Studio Code, HTML, CSS, JavaScript, Python, Django, OpenCV, NodeJS, MySQL, Unified Modeling Language (UML), Bizagi Modeler, and BrModelo. Several empirical tests were conducted, demonstrating the great potential of Player Baré for both video playback and supporting the subjective evaluation of perceived quality by customers. Additionally, Player Baré contributes to the monitoring carried out by both video streaming service providers and their regulatory agencies.
