New IO [io] 8000 / 8001 features
Media Delivery Index (MDI)
+ Measurement of network “quality“
+ Network jitter
+ Packet loss
+ Delay Factor (DF)– DF = [max(X) – min(X)] / media rate
+ Media Loss Rate (MLR)– MLR = [expected – received] / time interval

New IO [io] 8000 / 8001 features
Usage of Media Delivery Index (MDI)
1. Identify, locate and address any packet loss
2. Identify, locate and measure jitter (using DF)
3. Establish an infrastructure monitor
=> Monitor qualityof video stream => Show system margin
=> MDI requires a network margin indication that warns system operators of impending operational issues.
