For PID conflicts, the system will only automatically change the duplicated
output PID numbers. If both PE actions are set to
Map
, the output PID
number of the higher PE is changed. Otherwise, the output PID number of
the mapped PE is changed. For example, if the PMT PID of PE1 matches the
ES PID of PE2, the ES PID of PE2 is changed. The new PID number selected is
the next number that does not appear in the output of any PE and it is not in
the current transport input.

From the
Descrambled
drop-down list, choose whether the receiver should
scramble the output even if it is authorized to receive the channel. The default is
Descrambled.
Descramble Mode Description
Scrambled
Scrambles the output channel even if the PE is authorized and can
descramble the channel.
Descrambled
Descrambles the output channel, and passes in-the-clear channels.

Choose
Yes
to insert null packets in the output stream from the
Null Packet
Insertion
drop-down list. Otherwise, choose
No
. Null packets are always
inserted if the
Rate Control
is set to
User
and the configured output bit rate is
higher than the payload rate of the transport stream to be encapsulated.
Note:
We recommend that the
Null Packet Insertion
is set to
Yes
.

In the
SAP Multicast IP Address
field, enter the Session Announcement Protocol
destination IP address. This is the IP address where the SAP announcements are
sent, if required.
Note:
It is not recommended to change the default IP address (224.2.127.254).
9
In the
SAP Destination UDP Port
field, enter the SAP destination port number
(1 to 65534). This is the UDP port where the SAP announcements are sent, if
required.
Note:
It is not recommended to change the default SAP port 9875.

From the
FEC Scheme
drop-down list, choose the FEC packet sending
arrangement (Block Aligned or Non-Block Aligned). They are defined in the pro-
MPEG FEC and SMPTE-2022 standards.
