Voice & Video Analysis : Summary voice and video statistics
Summary voice and video statistics
Summary voice and video statistics are displayed in the Summary view of capture windows and saved capture files. A Voice & Video summary statistics group displays values collected and aggregated across all calls within the capture or file.
NOTE: If you want statistics for just one call, you must filter the data accordingly.
To view summary Voice & Video statistics:
1. Select the Summary view in a capture window.
2. Scroll to Voice & Video to see summary voice and video statistics for this capture.
The following table describes each voice and video statistic displayed in the Summary view:
Voice and Video Statistic
Description
Total Calls
All calls for the capture. Includes opened and closed calls, as well as recycled calls.
Current Calls
Calls currently displayed in the Calls view. Calls (Current) = Calls (Total) – Calls (Recycled).
Open Calls
Open calls currently displayed in the Calls view.
Closed Calls
Closed calls currently displayed in the Calls view.
Recycled Calls
Calls that are no longer in the Calls view. The call limit is 2000. After 2000 calls, calls are recycled. Calls (Recycled) = Calls (Total) – Calls (Current).
Average Call Duration
The average call duration (for all calls). Includes both open and closed calls.
Max Calls Time
Max Calls Time references the point in time when Omnipeek’s maximum call limit was reached. Once the maximum call limit has been reached, closed calls (and their respective media flows) drop out of the Calls/Media views as new calls come in.
Total Media Packet Loss %
Expected but never received packets as a percentage of expected packets (expected - captured) / (expected). Calculated using all media flows (supported codecs only) for all closed calls.
Voice Packet Loss %
Expected but never received packets as a percentage of expected packets (expected - captured) / (expected). Calculated using all voice score elements.
Voice Score Elements
Total number of voice media flows (supported codecs only) for all closed calls.
MOS-LQ
An estimated listening quality Mean Opinion Score, suitable for comparison with published MOS scores.
MOS-CQ
An estimated conversational quality Mean Opinion Score, incorporating factors (such as echo and delay) that affect conversational quality.
R Factor Listening
Provides an estimate of the effects that packet loss, jitter, and codec type had on listening quality for the call.
R Factor Conversational
Provides an estimate of the perceptual quality of the call, incorporating factors that affect conversational quality.
R Factor G.107
The ITU-T G.107 R-factor calculated for the audio stream.
Video Packet Loss %
Expected but never received packets as a percentage of expected packets (expected - captured) / (expected). Calculated using all video score elements.
Video Score Elements
Total number of video media flows (supported codecs only) for all closed calls.
MOS-AV
(MOS-Audio Video)
Audiovisual MOS, a 1-5 score that considers the effect of picture and audio quality and audio-video synchronization on overall user experience.
MOS-V
(MOS-Video)
Video Mean Opinion Score, a 1-5 score that measures the impact of the video codec, image size, frame rate, packet loss distribution, GoP structure, content, and frame loss concealment on viewing quality.
