    Abstract: Example implementations are directed to systems and methods for radio access network (RAN) load balancing that takes into account the end-to-end application requirements. Example implementations involve systems and methods by which RAN level information such as existing base station load and channel conditions can be combined with application information to perform application aware RAN load balancing. By implementation of the examples provided in the present disclosure, end-to-end quality of service (QoS) of the all users in the cellular network may be improved. Example implementations may be implemented by a method for dynamic caching and predictive maintenance of the network using intelligent video Quality of Experience (QoE) metrics feedback from the edge of the network.

    Abstract: MMTデータ伝送制御シグナリングの伝送量を削減する。 DDMTにおいて、MPUと合致させたディレクトリー下のファイルの詳細な情報を伝送せず、DAMTにおいて、ディレクトリーと合致させたMPU下のアイテムの詳細な情報を伝送しないようにする。ディレクトリーと合致するMPU下のアイテムの詳細情報を記述したファイルを1つのアイテムとして記述してそのMPUに転嫁して伝送する。また、DAMTに、MPUがディレクトリーと合致することを示すMPUノード記述子を配置して、ディレクトリーとのマッチングをとる。

    Abstract: A streaming method comprises determining deviation information representative of a deviation between an expected publication time of a media segment at a streaming server (10) and an actual publication time of the media segment at the streaming server (10). The streaming method also comprises transmitting the deviation information to a user client (20) requesting media segments from the streaming server (10). The deviation information can then be used by the user client (20) when scheduling transmissions of requests for media segments to the streaming server (10). As a consequence an improved and more accurate scheduling is achieved that can compensate for a jittery publication of media segments at the streaming server (10).

    Abstract translation: 流传输方法包括:确定表示流媒体服务器(10)上的媒体片段的预期发布时间与流媒体服务器(10)上的媒体片段的实际发布时间之间的偏差的偏差信息。 流传输方法还包括将偏差信息发送到从流传输服务器(10)请求媒体段的用户客户端(20)。 然后,当向流式传输服务器(10)调度对媒体片段的请求的传输时,该偏差信息可以由用户客户端(20)使用。 因此,实现了可以补偿流服务器(10)处的媒体片段的抖动发布的改进和更准确的调度。

    Abstract: 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.

    Abstract: 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.
