Abstract: In a streaming media method, a set of one or more server devices can provide media playlists that skip media segments. For example, a client device can receive a full media playlist from a server device, and the full media playlist can indicate that the server device supports providing updated playlists that are condensed by skipping media segments. The client device can then request an updated playlist that skips media segments and use that updated playlist to request and receive steaming content.

Abstract: Systems and methods use a new syntax defining a daterange tag that allows an author of a media stream to embed an arbitrary set of defined ranges in the media stream associated playlist. The defined ranges may be used to provide an overview of or otherwise define the playlist and media stream structure. When a playlist is updated and the timing window of the playlist advances, any daterange tags in the playlist that map to any defined range or media segment in the updated playlist will persist in the updated playlist. Any daterange tags in the playlist that map to defined ranges that have completed will be dropped from the updated playlist.

Abstract translation: 系统和方法使用新的语法来定义daterange标签，允许媒体流的作者在媒体流关联的播放列表中嵌入任意一组定义的范围。 定义的范围可以用于提供播放列表和媒体流结构的概述或以其他方式定义播放列表和媒体流结构。 当更新播放列表并且播放列表的定时窗口前进时，映射到更新的播放列表中的任何定义的范围或媒体片段的播放列表中的任何daterange标签将保持在更新的播放列表中。 映射到已完成的定义范围的播放列表中的任何daterange标签将从更新的播放列表中删除。
