Abstract: A system for evaluating quality of video delivered over a telecommunications network is provided. The system includes one or more monitoring probes coupled to one or more network interfaces providing direct communication between two or more networked devices. The monitoring probes are adapted to capture video data from the network interfaces. The system further includes a processor adapted to analyze the data captured by the monitoring probes. The processor is operatively configured to determine a number of lost data packets within the captured video data. The processor is further operatively configured to determine probability of unrecoverable losses within the captured video based on the determined number of lost data packets. The processor is also operatively configured to calculate a video quality index value based on the determined probability of unrecoverable loses.
