    • Systems, methods, apparatuses, and software for provide a digital media caching environment are provided herein. In one example, a method of operating a content node to provide a digital media caching environment is provided. The method includes receiving a request transferred by an end user device for digital media content. Responsive to the request, the method includes retrieving at least a header portion and a content subset of the digital media content from an origin server and transmuxing the content subset of the digital media content from an origin format into a stream format suitable for streaming to the end user device, and streaming the content subset in the stream format for delivery to the end user device.
    • 本文提供了用于提供数字媒体缓存环境的系统,方法,设备和软件。 在一个示例中,提供了操作内容节点以提供数字媒体缓存环境的方法。 该方法包括接收由终端用户设备传送来的用于数字媒体内容的请求。 响应于该请求,该方法包括从原始服务器检索数字媒体内容的头部部分和内容子集,并将数字媒体内容的内容子集从原始格式转换成适合流式传输到 最终用户设备,并以流格式流式传输内容子集以传送到最终用户设备。

    • Methods, media processing devices and cache nodes for enabling instant synchronization of processing of data units of a primary media stream and of one or more secondary streams by at least one media processing device are described. The method may comprise the steps of: selecting a primary media stream that is broadcasted by a broadcast source, said primary media stream being associated with at least one secondary stream; receiving data units of said primary media stream and data units of said at least one secondary media streams; providing cache timing information associated with a time delay between the availability by said at least one media processing device to data units of said primary stream and to corresponding data units of said secondary stream; and, requesting one or more cache data units from at least one cache server on the basis of said cache timing information, wherein at least part of said cache data units correspond to data units of said primary media stream that, at the time the primary media stream was selected by said media processing device, were already broadcasted by said broadcast source.
    • 描述了用于使由主要媒体流的数据单元和至少一个媒体处理设备的一个或多个次要流的处理的即时同步的方法,媒体处理设备和高速缓存节点。 该方法可以包括以下步骤:选择由广播源广播的主要媒体流,所述主要媒体流与至少一个次要流相关联; 接收所述主媒体流的数据单元和所述至少一个次要媒体流的数据单元; 提供与由所述至少一个媒体处理设备的可用性与所述主要流的数据单元和所述次要流的相应数据单元之间的时间延迟相关联的高速缓存定时信息; 并且基于所述高速缓存定时信息从至少一个高速缓存服务器请求一个或多个高速缓存数据单元,其中所述高速缓存数据单元的至少一部分对应于所述主要媒体流的数据单元, 流由所述媒体处理设备选择,已由所述广播源广播。
