短视频最近已成为现代社交媒体中短期用户生成内容（UGC）的流行形式。短视频内容通常长度不到一分钟，并且主要在智能手机上以垂直方向制作。虽然本质上仍然是流媒体，但短视频传输的明显特征是部署了在用户请求之前预加载的机制。后台预加载旨在消除启动时间，考虑到应用程序设计有助于按推荐顺序即时“滑动”到下一个视频，因此在体验质量 (QoE) 目标中，启动时间的优先级更高。在这项工作中，我们对四种流行的短视频服务进行了全面的比较。特别是，我们探索内容特征并评估每个服务的跨分辨率的视频质量。接下来我们描述每个服务所采用的预加载策略的特征。最后，我们进行了一项实验研究，以调查数据消耗并评估不同网络场景和应用程序配置下所实现的 QoE。
Short videos have recently emerged as a popular form of short-duration User Generated Content (UGC) within modern social media. Short video content is generally less than a minute long and predominantly produced in vertical orientation on smartphones. While still fundamentally being streaming, short video delivery is distinctly characterized by the deployment of a mechanism that pre-loads ahead of user request. Background pre-loading aims to eliminate start-up time, which is now prioritized higher in Quality of Experience (QoE) objectives, given that the application design facilitates instant 'swiping' to the next video in a recommended sequence. In this work, we provide a comprehensive comparison of four popular short video services. In particular, we explore content characteristics and evaluate the video quality across resolutions for each service. We next characterize the pre-loading policy adopted by each service. Last, we conduct an experimental study to investigate data consumption and evaluate achieved QoE under different network scenarios and application configurations.
