随着社区门户网站和视频分享网站的出现，多媒体内容的生产和消费急剧增加。由于移动设备提供的摄像机具有出色的视频记录功能，以及蜂窝网络提供的增强的数据速率，因此上传高质量的多媒体内容更加现实。目前，大多数视频流量都是基于HTTP的，它提供速率自适应流，称为HTTP上的动态自适应流（DASH）。在这项工作中，我们生成可以在LTE上行链路上支持的DASH视频流，然后将资源分配给视频生产者，从而使点播观众的QoE最大化。
With the advent of community portals and video sharing websites, production and consumption of multimedia content has increased tremendously. It is because of excellent video recording capabilities of cameras available with mobile devices, and enhanced data rates offered by cellular networks, that the uploading of high quality multimedia content is more realistic. Nowadays most of the video traffic is HTTP-based, that provides rate adaptive streaming, known as Dynamic Adaptive Streaming over HTTP (DASH). In this work we generate DASH video streams that can be supported on LTE uplink and then assign resources to the video producers such that the QoE of on-demand viewers is maximized.
