摘要:近年来,随着多媒体通信技术和视频压缩技术的迅速发展,各种数字视频业务广泛地
深入人们的生活。传统的基于 QoS 参数的视频质量方法使用网络的技术参数作为关键性能
指标,并不能直接反映用户的实际体验。而基于用户体验质量( Quality of Experience,
QoE)评价方法从用户的角度出发,评价用户对业务的总体满意程度,因此能够更准确的预
测用户的主观体验。本文提出了一个基于用户体验质量的无参考视频质量评价方法,用于
预测用户对视频流媒体业务的主观感受。通过进行视频质量主观人群测试,本文验证了这
一方法在预测视频流媒体业务的用户体验质量的优秀性能。

Abstract: With the development of munication technology and pression
technology, various digital video applications enter our daily life, which makes the requirement of
video quality assessment e more and more important. Conventional QoS based video
quality evaluation method, which work parameters as key performance indicators, cannot
directly reflect actual user experience. While QoE based method evaluates overall user satisfaction
from users' point of view. This paper proposes a QoE-based quality evaluation method on video
streaming service. The performance of this method has been verified through a subjective crowd
test.
