Absolute quality graph tab¶
This tab allows you to monitor one or more channels. Use the channel dashboard to select the channel or channels you want to monitor.
Click the <Add metric to graph> icon associated with each channel to add one or multiple graphs. Select a unique color for each graph to make it easy to identity.
There are five metrics. Each one may be color coded and selected to display average, maximum, minimum or range.
Video Quality: aggregation of all four metrics
MOS: mean opinion score; perceived video quality
Blur: image sharpness
Blockiness: discrete cosine transform (DCT) digital encoding artifact
Contrast: difference in color and light over the image
