摘要： The invention relates to a video quality monitor (101) for determining a network video quality measure (O) for a plurality of video clients (103_ 1,..., 103_N) in a communication network (115), each video client (103_1,..., 103_N) employing a video buffer for buffering video information receivable over the communication network (115). The video quality monitor (101 ) comprises: a data interface (107) configured to capture network data packets (113) comprising video information, the data interface (107) being configured to determine a network rate r(t) and a video playback rate v(t) from the captured network data packets (113); and a processor (111) being configured to emulate a storage capacity behavior of a set of video buffers to determine a set of video quality measures, each video quality measure being associated with a video buffer, each video buffer being associated with a probability of appearance in the communication network (115), the processor (111) being further configured to assign a probability of appearance of a respective video buffer to an associated video quality measure to obtain a statistical distribution of the video quality measures in the communication network (115), the statistical distribution of the video quality measures forming the network video quality measure (O).

摘要： The invention relates to a method (100) for modeling a service being delivered through a terminal to a user over a communication network during a service session, a progress of the service being determined by the user interacting with the service through the terminal. The method (100) comprises: determining (101) a service implementation type indicating an implementation of the service; assigning (103) a user experience centric service model to the service implementation type, the user experience centric service model comprising a first service state and a second service state; determining (105) a transition between the first service state and the second service state by observing the progress of the service during the service session; and determining (107) a user-originated reason for the transition based on the user experience centric service model.
