    摘要： Methods, systems and machine readable storage medium for allowing playback of streaming media at playback rates of other than 1× are described. In one embodiment, a method can determine different sets of I-frames that are available before a display deadline, where each set can have a different cadence, and one of the sets can be selected for download and display to achieve playback at other than 1×. Byte range requests from a client device can be used to retrieve each of the I-frames. Other methods, system and media are also described.

    摘要翻译： 描述了用于允许以除1×之外的回放速率回放流媒体的方法，系统和机器可读存储介质。 在一个实施例中，一种方法可以在显示截止日期之前确定可用的不同的I帧集合，其中每个集合可以具有不同的节奏，并且可以选择其中一个集合进行下载和显示以实现不同于1的播放 ×。 来自客户端设备的字节范围请求可用于检索每个I帧。 还描述了其他方法，系统和介质。

    摘要： Methods and apparatuses provide real-time or near real-time streaming of content using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method includes providing multiple redundant locations that provide media content to client devices using alternative streams. To implement failover protection, a first server device or first content distribution service creates a stream, or multiple alternate bandwidth streams and generates playlist file(s). A second server device or second content distribution service creates a parallel stream, or set of streams. A client attempts to download the playlist file(s) from a first uniform resource locator (URL) using a first stream associated with the first server device or the first content distribution service. If a client is unable to download the playlist file(s) from the first URL, the client attempts to switch to an alternate stream associated with another URL.
