摘要

本文利用H.264/AVC的错误隐藏机制和MPEG媒体传输的应用级前向纠错机制，对视频IP传输的主观QoE(体验质量)和客观应用级QoS(服务质量)进行了评估。从QoE的角度来看，这种相互作用有望实现更高效的视频流。实验处理两种内容，两种类型的每帧图像片数，两种类型的视频总比特率及其FEC码。我们试验了几种负载条件。然后，我们将FEC方案与三个码率值和无FEC方案进行比较。我们从评估结果中发现，适当的码率不仅取决于网络条件，还取决于内容。

[Paper] The Effect of MMT AL-FEC on QoE of Error-Concealed Video Streaming

In this paper, we assess subjective QoE (Quality of Experience) and objective application-level QoS (Quality of Service) of video IP transmission with error concealment mechanisms of H.264/AVC and AL-FEC (Application-Level Forward Error Correction) of MMT (MPEG Media Transport), which is an application-level protocol for video transmission. The mutual eﬀect is expected to realize more eﬃcient video streaming from a QoE point of view. The experiment treats two contents, two types of the number of slices per picture frame, and two types of the total bitrate of video and its FEC code. We experiment with several load conditions. We then compare FEC schemes with three code rate values and no FEC scheme. We show from the assessment results that the appropriate code rate for QoE enhancement depends on not only network conditions but also contents.
