    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: A method in an apparatus 301 for adapting play out of data packets during a handover of a user equipment (UE) 302 between a first radio network node (RNN) 304 and a second RNN 306. The packets relate to a real-time service application. The UE, first and second RNNs are comprised in a communications system 300. The method comprises generating at least one message to an adaptation control module. The at least one message is generated based on collected historical handover information and on current handover information. The method comprises further, by means of the adaptation control module, adapting the adapting the play out of the packets in dependence of the at least one message such that radio quality degradation in the real-time service application is controlled.
