摘要： Systems, methods and apparatus are provided for computing quality scores for a media session delivered using an adaptive streaming protocol, where the quality score may be an estimate of a mean opinion score. The quality score reflects the impact of network delivery on a viewer's quality of experience (QoE). In particular, the quality score is generally based on the effects of stream switch events, as stream switches may be the result of impaired network delivery. Other network events, such as re-buffering events may also be incorporated in the score.
摘要翻译：提供了用于计算使用自适应流传输协议传递的媒体会话的质量得分的系统，方法和装置，其中质量得分可以是平均意见分数的估计。质量得分反映了网络传递对观众体验质量（QoE）的影响。特别地，质量得分通常基于流切换事件的影响，因为流切换可能是网络传送受损的结果。其他网络事件，如重新缓冲事件也可以纳入评分。

摘要： Methods and systems for controlling quality of a media stream in a media session. The described methods and system control the quality of the media stream by controlling transcoding of the media session. The transcoding is controlled at the commencement of the media session and dynamically during the life of the media session. The transcoding is controlled by selecting a target quality of experience (QoE) for the media session, computing a predicted QoE for each of a plurality of control points, where each control point has a plurality of transcoding parameters associated therewith, selecting an control point of the plurality of control points, wherein the predicted QoE for the selected control point substantially corresponds with the target QoE and signaling the transcoder to use the selected control point for the media session.
摘要翻译：在媒体会话中控制媒体流的质量的方法和系统。所描述的方法和系统通过控制媒体会话的转码来控制媒体流的质量。在媒体会话开始时，媒体会话期间动态地控制转码。通过选择用于媒体会话的目标体验质量（QoE）来控制代码转换，计算多个控制点中的每一个的预测QoE，其中每个控制点具有与其相关联的多个代码转换参数，选择控制点所述多个控制点，其中所选择的控制点的所述预测QoE基本上与所述目标QoE相对应，并且指示所述代码转换器将所选择的控制点用于所述媒体会话。

摘要： Methods and systems for delivering multimedia content in various telecommunications networks while optimizing quality of experience (QoE). The described methods and systems implement a fast processing path and a slow processing path. In the fast processing path, minimal packet processing is performed to reduce latency. In the slow processing path, increased packet processing is performed to identify media sessions and to perform further data processing. The slow processing path can be used in an online or offline mode, depending on a current flow state.
