to or the Minimum Required Playout Delay (ms) status value.
The
Minimum Required Playout Delay
(in the
Status
section below) is the
sum of the maximum network jitter and the network path differential.
Keep the
Playout Delay
above the
Minimum Required Playout Delay
for
proper operation of IP receivers.
IGMP Leave Delay (ms)
When in Make After Break Switch Mode, as set on the
Program
Configuration: Input Tab
(on page 94), this value (measured in
milliseconds) is how long this device will wait for the current stream to
leave before timing out on the Next Source switch.
Check with the network switch documentation to determine how long the
switch will take to perform an IGMP leave.
IGMP Join Delay
When in Make Before Break Switch Mode, as set on the
Program
Configuration: Input Tab
(on page 94), this value (measured in
milliseconds) is how long this device will wait for the current stream to join
before timing out on the Next Source switch.
Check with the network switch documentation to determine how long the
switch will take to perform an IGMP join.
Status
Minimum Required Playout
Delay (ms)
This read-only parameter reports the minimum required playout delay
level in milliseconds.
Switch Duration
The Switch Duration indicates now long a switch will take to perform a
change from one multicast stream to another. This value is affected by
the Playout Delay as well as the IGMP join & leave Delay values.

Video IP DSCP
This field allows you to choose the Differentiated Services Code Point (DSCP) value.
Options include:
•
Default Forwarding: best effort traffic
•
Expedited Forwarding: low-loss, low-
latency traffic
•
Voice Admit: the same as default
forwarding, except with a call-admission
control that prevents oversubscription
