摘要： The invention relates to a method for performance reporting in a wireless network, wherein at least one terminal is associated to a terminal report server by means of information in the terminal. Prior to initiating the performance report, information on operator identity is retrieved. The operator identity is combined with information identifying the associated terminal report server to compile a fully qualified domain name. Connectivity information to the terminal server report is requested and received from a domain name server, whereupon a performance report session to the terminal report server is initiated using the received connectivity information. The invention also relates to a terminal wherein the inventive method is applied.

摘要： Method and arrangement for supporting quality estimation of streamed video. The method comprises obtaining an indicator of a number of discontinuities related to a segment of a video stream, and an indicator of a number of received packets related to said segment of the video stream during a predefined period of time. The method further comprises converting said obtained indicators, by use of at least one mapping function, into a set of parameters suitable for use as input parameters to a parametric video quality estimation model. The method and arrangement enables parametric quality estimation based on the basic parameters reported by legacy equipment.

摘要： Identifying lost data packets and at least two intra coded frames of a video stream can be useful in determining the quality value of the video stream. The intra coded frames having maintained image quality can be determined based on estimating whether an intra coded frame is associated with a lost data packet. This allows a distance to be estimated between each one of the lost data packets and a next respective, subsequent intra coded frame having a maintained image quanta. Based on the distances, a quality value for the video stream can be generated.

摘要： One or more embodiments herein dynamically and objectively estimate user-perceived quality of an encoded video stream in dependence on the underlying video content of that stream. Estimation processing according to these embodiments includes generating a chronological sequence of the absolute or relative sizes of encoded video frames in the stream. Processing further entails analyzing this sequence to identify a plurality of reference characteristics that are defined in a reference model. These reference characteristics are more specifically defined in the reference model as parameters that characterize or are otherwise associated with content-dependent variations in user-perceived quality. For example, the reference characteristics in some embodiments comprise reference patterns or reference statistical measures that have been determined based on analyzing frame size sequences generated for reference video streams with known qualities. Regardless, processing finally includes estimating the user-perceived quality of the stream based on the identified reference characteristics, according to the reference model.
摘要翻译：本文中的一个或多个实施例根据该流的底层视频内容动态和客观地估计编码视频流的用户感知质量。根据这些实施例的估计处理包括生成流中编码视频帧的绝对或相对大小的时间顺序。处理进一步需要分析该序列以识别在参考模型中定义的多个参考特征。这些参考特征在参考模型中被更具体地定义为表征或以其他方式与用户感知质量的内容相关变化相关联的参数。例如，一些实施例中的参考特征包括已经基于分析为已知质量的参考视频流生成的帧大小序列而确定的参考模式或参考统计量度。无论如何，处理最终包括根据参考模型基于所识别的参考特征来估计流的用户感知质量。

摘要： There are provided a plurality of methods for detecting a scene change in a streamed video, the streamed video comprising a series of pictures. An example method comprises calculating, for a plurality of positions, a difference between the costs of coding macro-blocks at the same position in successive pictures. The method further comprises identifying a new scene when the sum of the differences for a plurality of positions meets a threshold criterion. There is further provided a method of determining the perceptual impact of a packet loss on a streamed video the method comprising: identifying a packet loss; and determining if the lost packet contained information relating to a picture at the start of a new scene, wherein a new scene is detected using one of the methods disclosed herein.
