摘要： A device and method provides a means for monitoring a media segment of a Real-time Transport Protocol (RTP) media stream without interfering with end-to-end monitoring of the RTP media stream. The device includes a media segment monitor to generate segment control messages associated with a selected segment of the RTP media stream transmitted between a source endpoint and a destination endpoint in a packet network. The device further includes an interface to transmit and receive the segment control messages; and a processor to process the segment control messages, the segment control messages including call quality metrics related to the selected segment of the RTP media stream.

摘要： An audio and/or visual transmission quality device estimates transmission quality as perceived by a user based on observation and processing of objective metrics. The device preferably includes a primary integrator to generate an instantaneous estimate of user annoyance based on occurrence of frame loss events in a received signal. The device further preferably includes secondary integrators to process the instantaneous estimate of user annoyance in selected time intervals and generate a plurality of time-varying estimates of user annoyance valid over the selected time intervals. The device may further include a plurality of scaling modules to scale the plurality of time-varying estimates and generate a corresponding plurality of estimates of transmission quality as perceived by the user. The device may further include a modulation network to modify a sensitivity of the primary integrator to the occurrence of frame loss events in the received signal.

摘要： An embodiment may include an apparatus comprising a dejitter buffer to receive packets containing audio data, a codec coupled with the dejitter buffer, the codec to receive coded audio frames from the dejitter buffer and decode them, and a concealed seconds meter coupled with the dejitter buffer, the concealed seconds meter to record concealment events by the decoder to provide an objective measure of media impairment. Another exemplary embodiment may be a method comprising receiving packets containing audio information at a dejitter buffer, decomposing the packets to coded audio frames, sending the coded audio frames to a decoder and decoding the frames, generating a concealment output stream if the decoder does not receive a valid frame from the dejitter buffer, and recording concealment events to provide an objective measure of media impairment.
