Resumo

O tráfego de vídeo em redes aumenta exponencialmente, e, assim, a quantidade de tempo que deve ser usado para navegar por catálogos de conteúdos. Portanto, são necessários sistemas de vídeo sob demanda [VoD] que possam ter em conta as emoções como parâmetro para acelerar o acesso aos conteúdos. Este artigo apresenta o desenho e implementação de um serviço de VoD baseado em emoções, cujos principais componentes são: o catálogo de conteúdos musicais conformado e o sistema hardware-software que permite definir o nível de estresse mental e a inferência de emoções do consumidor enquanto este interage com o sistema. O produto final foi submetido a testes de eficiência e stress, com resultados satisfatórios: o tempo utilizado pelo servidor web com 200 conexões sequenciais variou entre 0,050 e 0,675 segundos, e entre 0,030 e 0,675 segundos quando simultâneas. Também conseguiu responder adequadamente perante 20.000 conexões sequenciais, com tempos de resposta de menos de 1 a 36 segundos e suportar sem entrar em colapso, 18.000 conexões simultâneas, com tempos de resposta entre 7 e 62 segundos. O projeto oferece um serviço open source que fornece as bases para futuros projetos.
