QoE Metric | Description |
---|---|
Corruption duration metric | The time period from the NTP time of the last good frame before the corruption to the NPT time of the first subsequent good frame |
Successive loss of RTP packets | The number of RTP packets lost in the successive per media channel |
Frame rate | The playback frame rate is equal to the number of frames displayed during the measurement resolution period divided by the time duration (in seconds) of the measurement resolution period |
Jitter duration | Jitter happens when the absolute difference between the actual playback time and the expected playback time is larger than JitterThreshold milliseconds |
Sync loss duration | Sync loss happens when the absolute difference between value A and value B is larger than SyncThreshold milliseconds |
Round-trip time | The RTT consists of the RTP-level round-trip time, plus the additional two-way delay due to buffering and other processing in each client |
Average codec bitrate | The bitrate is used for coding “active” media information during the measurement resolution period |
Codec information | The codec information metrics contain details of the media codec settings used in the receiving direction during the measurement resolution period |
