Major / Minor Tracking – Place a check mark in this box to enable this mode.
When the unit is in this mode, the service will be selected / maintained using the
major and minor channels referenced from the VCT within an ATSC PSIP
(ATSC A/65) compliant Transport Stream. If this is not ticked the unit tracks the
service by service ID from within the PAT. Within this pair the major channel is
normally allocated by the FCC per broadcaster and the minor channel uniquely
identifies the service, this means in practice the minor channel is used for
tracking.
MSD Hunt – Place a check mark in this box to enable this mode. When the unit
is in this mode it will after first acquisition or update of the PAT, select every
service within the PAT up to the maximum of 24 services for decryption. This
can be confirmed on the Service Plus tab. The first service in the list will be set
to decode.
Descrambling license has been enabled for any of the following CA
systems: BISS, DVB-CI or Director.
MSD Drop – Place a check mark in this box to enable this mode. If MSD Hunt is
enabled and MSD Drop is enabled when a new PAT is detected, the unit will
review the new Service List. If the current selections are not in the service list
those selections will be cleared. If MSD Drop is disabled, unit will hold onto all
current selections until new services are selected. See Figure 3.95.
