摘要： Provided is a service quality of experience (QoE) predicting and managing system. The service QoE predicting and managing system may include a media quality measurement system (MQMS) to measure a QoE of media, and a quality of service (QoS)/QoE control system (QCS) to measure QoS parameter information, to predict the QoE based on the measured QoS information, to calculate a QoS parameter adjustment value by comparing and analyzing the QoE measured by the MQMS and the predicted QoE, and to transmit the calculated QoS parameter adjustment value to a service quality control system (SCS).

摘要： Provided is a method of assessing an image quality of each of a base layer and an enhanced layer using a different scheme to assess a quality of a multi-level video based on assessment results. A multi-level video quality assessing system includes: a bitstream extractor to separate a multi-level video into a base layer bitstream and an enhanced layer bitstream; a base layer quality assessment module to generate quality assessment result information of a base layer image by assessing an image quality of base layer bitstream; an enhanced layer quality assessment module to generate quality assessment result information of an enhanced layer image by assessing an image quality of enhanced layer bitstream; and a final video quality assessment module to assess a quality of experience (QoE) of multi-level video based on quality assessment result information of each of the base layer image and the enhanced layer image.
摘要翻译：提供了使用不同的方案来评估基础层和增强层中的每一个的图像质量的方法，以基于评估结果来评估多级视频的质量。多级视频质量评估系统包括：将多级视频分离成基层比特流和增强层比特流的比特流提取器; 基层质量评估模块，通过评估基层比特流的图像质量来生成基本层图像的质量评估结果信息; 增强层质量评估模块，通过评估增强层比特流的图像质量来生成增强层图像的质量评估结果信息; 以及基于每个基本层图像和增强层图像的质量评估结果信息的最终视频质量评估模块来评估多级视频的体验质量（QoE）。
