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.
