Neste artigo, discutimos os requisitos de QoE (Qualidade de Experiência) para MVV (Multi-View Video) e transmissão de áudio em redes IP e estudamos o efeito do tempo de buffer de playout, conteúdo e interfaces de mudança de ponto de vista na QoE e no comportamento do usuário. Ao contrário de trabalhos anteriores, que discutem principalmente a transmissão MVV a partir de aspectos de codecs de vídeo, estudamos MVV e transmissão de áudio sob vários tráfego IP e condições de atraso por experimento. Comparamos dois esquemas: um esquema que o usuário observa a partir de um único ponto de vista e aquele em que ele pode escolher um ponto de vista dentre vários. Como resultado, mostramos que os usuários preferem o esquema onde podem escolher um ponto de vista entre vários pontos de vista. Descobrimos que ao usar o tempo de buffer adequado, os usuários sentem mudanças de ponto de vista mais rápidas; melhora sua satisfação em comparação com quando assistem de um único ponto de vista. Percebemos também que o usuário presta mais atenção à degradação do vídeo ao assistir de um único ponto de vista. Observamos que os usuários tendem a mudar o ponto de vista com mais frequência em trânsito leve e baixo atraso.

Abstract: In this paper, we discuss QoE (Quality of Experience) requirements for MVV (Multi-View Video) and audio transmission over IP networks and study the effect of the playout buffering time, contents and viewpoint change interfaces on the QoE and user's behavior. Unlike previous works, which mainly discuss MVV transmission from aspects of video codecs, we study MVV and audio transmission under various IP traffic and delay conditions by experiment. We compare two schemes: a scheme that the user watches from a single viewpoint and the one that he/she can choose one viewpoint from many ones. As a result, we show that the users prefer the scheme where they can choose one viewpoint from many ones. We have found that when using proper buffering time, the users feel faster viewpoint changes; it improves their satisfaction compared to that when they watch on a single viewpoint. We have also noticed that the user pays more attention to the degradation of the video when watching on a single viewpoint. We have observed that the users tend to change the viewpoint more frequently in light traffic and low delay.
