+#### ```abrBandWidthFactor```
+(default : 0.8)
+
+scale factor to be applied against measured bandwidth average, to determine whether we can stay on current or lower quality level
+If ``` abrBandWidthFactor * bandwidth average < level.bitrate ``` then ABR can switch to that level providing that it is equal or less than current level
+
+#### ```abrBandWidthUpFactor```
+(default : 0.7)
+
+scale factor to be applied against measured bandwidth average, to determine whether  we can switch up to a higher quality level
+If ``` abrBandWidthUpFactor * bandwidth average < level.bitrate ``` then ABR can switch up to that quality level
