Table 6-4 provides examples of this functionality. In the example, the pool contains Input Video, AES 1,
AES 3, AES 5, and AES 8. Also in each case, the transition will be from the primary bank to the
secondary one.

In this case, both banks have the same
signals present. If any of the signals in
the primary bank disappears, a switch to
the secondary bank will occur.

The secondary bank is missing AES 1. If
AES 3, 5, or 8 disappear in the primary
bank, a switch will NOT occur, because
the secondary bank does not have AES 1
present. If AES 1 also disappears, then a
switch will occur.
A switch will occur if the input video signal
is lost, regardless of the state of the AES
signals.

In this case, a switch will occur because
