Abstract: Technology for supporting dynamic adaptive streaming over hypertext transfer protocol (DASH) is disclosed. A quality metric may be determined, at a network device, for each of a plurality of media content segments in a defined representation that are described in a media presentation description (MPD) file. Media content segments may be identified in the defined representation in which the determined quality metric is below a selected threshold. The identified media content segments may be replaced with corresponding media content segments from a different representation that are described in the MPD file to form a modified MPD file, wherein the quality metric for the corresponding media content segments is greater than the selected threshold in order to provide a substantially constant quality playback of the media content segments in the defined representation.

Abstract: Technology for receiving streaming media content is disclosed. A media presentation description (MPD) for the streaming media content can be received at a user equipment (UE). A streaming interval can be selected for the streaming media content. A power consumption level can be calculated for receiving the streaming media content at each of a plurality of media content representations that are described in the MPD. A media content representation can be selected from the plurality of media content representations based on: the power consumption level associated with receiving the streamed media content at the media content representation; and power status information for the UE, using the one or more processors of the UE. The streaming media content can be received at the selected media content representation, at the UE, in accordance with the streaming interval. The streaming media content can be played at the UE.

Abstract: Client devices streaming content adhering to the Dynamic Adaptive Streaming over HTTP (DASH) standard may send Quality of Experience (QoE) information to a DASH manager and request server status updates from the DASH manager. The server status updates may include information regarding one or more content servers including online status information, content availability, load, and content server recommendations. The content server recommendations may be a relative ranking of servers that the DASH manager recommends that the client device select as a source server for desired media content. Based on the server status update information, the client may select a source server. The QoE information sent to the DASH manager may be used by the DASH manager, along with server status information, to generate the relative ranking.

Abstract translation: 遵循动态自适应流过HTTP（DASH）标准的客户端设备流式传输内容可以向DASH管理器发送体验质量（QoE）信息，并从DASH管理器请求服务器状态更新。 服务器状态更新可以包括关于一个或多个内容服务器的信息，包括联机状态信息，内容可用性，负载和内容服务器推荐。 内容服务器推荐可以是DASH管理器建议客户端设备选择作为所需媒体内容的源服务器的服务器的相对排名。 根据服务器状态更新信息，客户端可以选择源服务器。 发送到DASH管理器的QoE信息可以由DASH管理器与服务器状态信息一起使用以产生相对排名。
