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 translation: 公开了用于支持超文本传输​​协议（DASH）上的动态自适应流的技术。 在媒体呈现描述（MPD）文件中描述的以定义的表示中的多个媒体内容段中的每一个可以在网络设备处确定质量度量。 可以在所确定的质量度量低于所选择的阈值的所定义的表示中识别媒体内容段。 所识别的媒体内容段可以由来自在MPD文件中描述的不同表示的对应的媒体内容段替换以形成修改的MPD文件，其中对应的媒体内容段的质量度量大于所选择的阈值，以便 以定义的表示提供媒体内容段的基本上恒定的质量回放。
