IPTV Analysis
The IPTV Analysis tab allows you to configure the unit for video testing.
The parameters are the following:
³
Join Multicast Address is the 
multicast address of the channel 
that is automatically requested to 
join when running the video 
analysis during the auto test.
³
Monitoring Interval is a list of 
time interval values - 8, 16, 32, or 
64 min - to set the length of time 
for which data is plotted on a graph.
³
Test Thresholds allow you to set critical quality of service (QoS) 
values for delivering IPTV over DSL.
³
Max Packet Jitter (ms) is a value in accordance with the network 
characteristics, ranging from 0 through 99 milliseconds, to be used 
as the pass or fail criteria for QoS.
³
Max Lost Packet Ratio (%) is a percentage of the total packet rate, 
ranging from 0 through 10.00, to use as pass/fail criteria for QoS.
³
Max ZAP Time(ms) is the time in milliseconds, ranging from 
0 through 999, required for a channel change and to be considered 
when evaluating IPTV QoS.
³
MAX PCR Jitter (ms) is the short-term variation in milliseconds, 
ranging from 0 through 999, of the arrival of the PCR (program 
clock reference) information at the video decoder.
³
Max MDI:DF (ms) is the media delivery index (MDI) to delay factor 
(DF) in milliseconds, ranging from 0 through 999.
³
Max MDI:MLR (packs/s) is the media delivery index (MDI) to 
media loss rate (MLR) in packets lost per second, ranging from 
0 through 999.
