在基于分组的网络上传送的多媒体服务的增加引起了终端用户更高的质量期望。考虑到视听内容可能沿着广播系统遭受的不同降级，这导致了对用于评估视听内容的观众所感知的体验质量的技术的深入研究。在本文中，一个全面的研究影响IPTV中的视频和音频的传输错误的影响。有了这个目的，主观评估测试进行了提出了一种新的方法，试图保持尽可能接近家庭环境的观看条件。此外，并排格式的3DTV内容已被用于实验中，以比较退化的影响。结果提供了一个更好的理解传输错误的影响，并表明，与3DTV的第一种方法相关的QoE是可以接受的，但它引起的视觉不适应该减少。
The increase of multimedia services delivered over packet-based networks has entailed greater quality expectations of the end-users. This has led to an intensive research on techniques for evaluating the quality of experience perceived by the viewers of audiovisual content, considering the different degradations that it could suffer along the broadcasting system. In this paper, a comprehensive study of the impact of transmission errors affecting video and audio in IPTV is presented. With this aim, subjective assessment tests were carried out proposing a novel methodology trying to keep as close as possible home environment viewing conditions. Also 3DTV content in side-by-side format has been used in the experiments to compare the impact of the degradations. The results provide a better understanding of the effects of transmission errors, and show that the QoE related to the first approach of 3DTV is acceptable, but the visual discomfort that it causes should be reduced.
