近年来，随着OTT （Over the Top）服务的兴起，视频流量大幅增加。除了传统的视频点播（VoD）流媒体服务（如Netflix， YouTube），直播视频服务（如Twitch）。tv, youtubeaming, Facebook Live)也带来了巨大的互联网流量份额。在直播服务中，游戏视频流占有很大的份额，比如Twitch。目前，仅电视就负责美国第四高峰的互联网流量。因此，由于游戏视频是人工合成的，我们有必要研究一下游戏视频在压缩和最终用户QoE方面的特殊性。在本文中，我们对常规视频和游戏视频进行了客观和主观的质量比较研究，其中30个视频序列（每种类型15个）使用最先进的编码器HEVC进行编码。我们讨论了这两种视频类型之间的相似性和差异性，并讨论了如何使用这些观察结果来改善最终用户的QoE。
Recent years have seen a tremendous increase in video traffic with the rise of Over The Top (OTT) services. Along with traditional Video on demand (VoD) streaming services (e.g., Netflix, YouTube), live video services (e.g., Twitch. tv, YouTubeGaming, Facebook Live) have also resulted in a tremendous share of Internet traffic. Among the live streaming services, gaming video streaming has a major share, with Twitch.tv alone currently responsible for the fourth highest peak Internet traffic in the US. As a consequence of this, and due to the fact that gaming videos are artificial and synthetic, it is worth investigating the specificity of gaming videos in relation to compression and the consequent end user QoE. In this paper, we present an objective and subjective quality comparison study for regular videos and gaming videos, with 30 video sequences (15 per type), encoded using the state of the art encoder HEVC. We discuss the similarity and dissimilarity between the two video types and also discuss how these observations can be used to improve the end user QoE.
