基于比特流的方法直观地适合于网络视频服务的质量评估，目前在研究和标准化活动方面正在进行密集的研究。本文分析了可能影响网络视频质量的因素，综述了基于码流的视频质量评估的最新技术和标准化进展。根据对比特流的不同访问级别，描述并比较了三种类型的模型：参数模型、包层模型和比特流-层模型。
Bitstream-based methods are intuitively suited for quality assessment of networked video services, and are currently under intense investigations in terms of research and standardization activities. This article examines the factors that may affect the quality of the networked video, and reviews the state-of-the-art techniques as well as standardization progress in bitstream-based video quality assessment. According to different levels of access to the bitstream, three types of models are described and compared: the parametric, packet layer, and bitstream-layer models.
