The following delays occur:
Maximum Delay
Time taken for the signal to travel from the playout center (MIP inserter) to the
transmit antenna for regular transmission. This delay is set in the SFN adapter and
is the default for all transmitters of the SFN.
Network Delay
Time taken for the signal to travel from the playout center (SFN adapter) to the
input of the exciter. With IP feed, the time for forward error correction (FEC) and
packet reordering is added to the Network Delay. This delay depends on the used
transmission path.
Processing Delay
Minimum transit time of the signal through the exciter. This delay depends on the
set transmission parameters.
Dynamic Delay
Period of time by which signal processing is delayed artificially in order to achieve
the desired time of transmission.
Total Delay
Actual transit time of the signal through the exciter. This time is the sum of Pro-
cessing Delay plus Dynamic Delay.
Static SFN Delay
Positive or negative offset (set manually for the individual transmitter location) of
the time of transmission relative to the regular time of transmission preset under
Maximum Delay. The Static SFN Delay is used to compensate for differences
between transmission systems from different manufacturers.
Dispatch Time
This is the actual time of transmission. It is the networkwide Maximum Delay plus
the transmitterspecific Static SFN Delay.
