    摘要： It is provided a method, performed by a MOS, Mean Opinion Score, estimator, for predicting a multimedia session MOS. The multimedia comprises a video and an audio, wherein video quality is represented by a list of per time unit scores of a video quality, an initial buffering event and rebuffering events in the video, and wherein audio quality is represented by a list of per time unit scores of audio quality. The method comprises: generating video features from the list of per time unit scores of the video quality; generating audio features from the list of per time unit scores of the audio quality; generating buffering features from the initial buffering event and rebuffering events in the video; and estimating a multimedia session MOS from the generated video features, generated audio features and generated buffering features by using machine learning technique.

    摘要： A method of determining loss of IP packets that are transported over a network (102), where each IP packet comprises a number of data packets. The method comprises: i) extracting (501) a first data packet from a first IP packet (41), ii) extracting (502) a second data packet from a second IP packet, iii) retrieving (503, 504) a first sequence number from a first data packet and a second sequence number from a second data packet, where each of the sequence numbers is indicative of a sequence of data packets and has a value belonging to a set of a number of unique values, iv) calculating (505) a difference (&Dgr;cc) between the sequence numbers, and v) determining (506) a number (k) of lost IP packets, as a function of the difference (&Dgr;cc) between the sequence numbers. Related computer readable medium and customer equipment are also described.
