to open the SIS data schedule window. Ten SIS
messages are available for scheduling, as shown
in the following illustration.
Choices that are not supported in the current
iBiquity software release are grayed out (Call Sign
Universal and Slogan Universal).
The Station Message box will be grayed out if
the Message entry box does not have any text en-
tered in the
System Mode Settings window.
SIS data is structured into 32 payloads, which
constitute one frame. These 32 payloads are di-
vided into 16 blocks of two payloads each and are
numbered along the left side of the SIS window.
SIS messages vary by payload requirements.
Some messages require a single payload, some
require two payloads, or more, to fully deliver their
message content. It all depends upon the length of
the respective message.
SIS Messages are deployed in the schedule as
either single or double message payloads. You are
free to schedule your SIS messages however you
choose, but there are some restrictions. Single pay-
load messages can generally be placed anywhere,
while multiple payload messages must be placed
in the first payload of a block leaving the second
payload of that block empty.
There are a few arcane restrictions regarding
the placement of payloads beyond the above de-
scription. Fortunately, the ECC software disciplines
these restrictions for you. You simply click and drag
the desired SIS message block from the top of the
window to one of the available payload slots. Per-
mitted placement choices are clearly indicated, and
the application will not permit you to place a mes-
sage in a restricted payload location.
Note that if a message requires more than two
payloads to deliver its respective message, only a
portion of the message gets broadcast each time
the message is scheduled since each frame (16
blocks) are sent at a rate of one frame per 1.5
seconds.
