中文摘要：
网络视频质量评估是保证网络视频业务质量的关键技术。依据对网络视频码流的介入程度,客观网络视频质量评估模型可分为参数规划模型、分组层评价模型、比特流层评价模型、媒体层评价模型及混合评价模型5大类。首先介绍了网络视频质量评估方法的各种分类及应用场景,并基于影响网络视频质量的重要因素,分别详细综述了各模型的特点、关键技术、最新研究成果及标准化进程。
英文摘要：
Assessment of networked video quality is the key to ensure the quality of service for networked video applica-tions.From the viewpoint of the employed video information and the level of access to the bit-stream,objective qual-ity-assessment models can be categorized into the parametric-planning model,parametric packet-layer model,parametric bit-stream-layer model,media-layer model,and hybrid model.The classification and application of networked video quality assessment was first introduced.Then the characteristics,key techniques,state-of-the-art,and standardization process of each model were described based on the key factors which impact the networked video quality.
