SIS schedule
The Station Information Service (SIS) provides broadcast station identification and control
information. SIS is transmitted in a series of SIS Protocol Data Units (PDUs). SIS consists of a
number of messages used by the receiver to quickly identify all of the services being broadcast
by your HD station, such as station ID, call sign, station location and service messages. HD
stations send out a 1 frame (made up of 32 payloads) SIS message every 1.5 seconds. These
messages are independent of PSD, audio or data services
From the
SIS Schedule
menu (see Figure 8.140 ) you can set to operate from a basic or default
schedule or you can define up to 16 blocks (0 through 15), each containing up to two payloads,
depending on the length (in bits) of the information
selected
.

Setting basic schedule
When you select
Set Basic Schedule
from the
SIS SCHEDULE
menu (see Figure 8.141 ) you can
set the SIS schedule to operate from a basic schedule. The basic schedule is used for test
purposes and only broadcasts the station FCC ID. It is not intended for normal operation
.
