Abstract: Techniques are described for providing rendition manifests for the playback of video content or other types of content on a user device. The response to a request for content may serially include data objects for one or more rendition manifests as Data Uniform Resource Indicators (URIs) or in another data format. By incorporating the data of the rendition manifest(s) in the response, implementations may forego a network request to retrieve the rendition manifest(s) and thus reduce the latency for presenting content. In some cases, the incorporated rendition manifest(s) may list locations for a subset of chunks of a content file, and the content may be marked as live content, to reduce the size of the response and further reduce latency. In some cases, locations for chunks from multiple content files may be included in a same set of one or more rendition manifests in the response.

Abstract translation: 描述了用于提供用于在用户设备上播放视频内容或其他类型的内容的再现清单的技术。 对内容请求的响应可以串行地包括用于一个或多个再现清单的数据对象作为数据统一资源指示符（URI）或另一数据格式。 通过将再现清单的数据合并到响应中，实现可以放弃网络请求来检索再现清单，从而减少呈现内容的延迟。 在一些情况下，所合并的再现表单可以列出内容文件的块的子集的位置，并且可以将内容标记为实况内容，以减小响应的大小并进一步减少等待时间。 在一些情况下，来自多个内容文件的块的位置可以包括在响应中的一个或多个再现清单的相同集合中。
