Network Redundancy Application
The stream is duplicated for redundancy purposes and is conveyed by
two paths, one being more direct than the other one.
Figure 1-12. System application: network redundancy
For instance, on Figure 1-12 , the stream is conveyed more quickly by
path #1 than by path #2. Consequently, the second stream arrives later
tha
n the first one.
In this case, Amethyst III’s time delay feature lets you apply a delay on
input 1 (path #1). Secondly, the delay compensati
on feature lets you
resynchronize the two streams. Stream conveyed by path #1 is thus
del
ayed to be synchronized with the stream of path #2. In this case,
sync
hronization is made on a user-defined PID (e.g.: PAT with PID=0).
