GUI Überblick

Video Metrics
Video Perceptual Quality provides the most essential QoE scoring metrics such a Video MOS scores
Degradation Factors provide insight into the nature of MOS score
Video Jitter Metrics provide amount of
Average Frame and I-frame Inter Arrival Jitter
Average and Peak Frame Arrival Delay in miliseconds
Video Scene Analysis Metrics provide proportions of the stream with Detail, Panning, Motion and Static Image.
These factors weight on the overall Video MOS score.

Packets Metrics
Transport Packets are MPEG-TS packets that carry Packet Elementary Streams (PES).
Statistics of these MPEG-TS Packets such as lost, discarded, corrected, out-of-sequence and duplicated packets allow detection of this major source of video picture degradation.
RTP Packet Metrics ( if available) are statistics of RTP protocol encapsulation. RTP encapsulation is optional and is used to provide independent timestamping to video and audio. But it also adds overhead to the transmission.
Tracking RTP statistics allows problem isolation to the RTP encapsulating device.
Jitter Metrics focus on the PCR Jitter which is defined as TimeStamp arrival time jitter.
PCR Jitter is a mjor contributor to loss of frames due to router or STB buffer overflow.

TR101290 Metrics
TR 101290 Second Priority list Error Counters recommended for continuous or periodic monitoring
TR 101290 First Priority lists Loss and Error counters that are essential for video de-codability

Audio Metrics
Audio Decription Information is similar to Video Decription Information providing essential reference information about the stream.
Audio Bandwidth Metrics provides bandwidth average and peak rate with and without headers
Audio Perceptual Quality Metrics are MOS scores with subjective test content calculated with a specialized VQMON audio algorithm.
Degradation Factors provide severity of degradation due to Packet Loss, Packet Discard, Codec, a Recency of burst packet loss

Video Frames Metrics
Video Frames (MPEG-TS) statistics provide the total number of Received and Impaired frames I, P , B and optional SI and SP. This breakdown allows better diagnostics of the distorted video.
Packet statistics such as Packet Lost, Packets Discarded and Packets Impaired correspond to the MPEG-TS frame statistics and they allow more detail breakdown of the diagnostics.

Video Bandwidths Metrics
Video Bandwidth of I, P,B, SI and SP frames provides a useful information for traffic engineering. Looking and MOS and other metrics one can determine how much less or more bandwidth to add or reduce to maintain the quality goal and bandwidth utilizations at the same time.

Graphs
Any two metrics can be displayed as histograms allowing correlation of events for diagnostics
