Loss of Input PSI Timeout

Loss of PSI is used to determine when a service that was previously received is no
longer on the input stream. For a service to be remultiplexed by the APEX1000, the input
PAT must reference the applicable service number. In addition, the input PMT must be
received.
The Input PAT is used to determine the input PMT PID value. If either the PAT or the
PMT are determined to be missing, the APEX1000 will stop remultiplexing the service.
This provides you with a real time update for each service.

Detection of Lost Input Services

The APEX1000 can detect the loss of an input service, based on missing PSI on the
input. This is an option that may allow some receivers/decoders to better react to lost
services.
If this mode is enabled, the behavior described below may be expected:
•
If an Input PMT is deemed lost: To ensure that the associated SN reference is
removed, the APEX1000 will remove the associated output PMT and will update the
output PAT. If the input PMT reappears, the APEX1000 will immediately begin
re-inserting the output PMT.

Definition/Range
The APEX1000 can detect the loss of an input stream based on missing PSI on
the input (missing PATs and/or PMTs). (This field is grayed out if Detect Loss of
PSI Enabled is not checked.)
Range: 1 – 21600 (seconds)
See Loss of Input PSI Timeout below for more information.
Note: For VOD input streams, this setting should be set to at least 10 minutes
(600 seconds).
Insert a value to bound the minimum PSI version number for PATs and PMTs.
Range: 0 – 30
Caution: PSI Range Stop must be greater than PSI Range Start.
Insert a value to bound the maximum PSI version number for PATs and PMTs.
Range: 1 – 31
Caution: PSI Range Stop must be greater than PSI Range Start.
Insert a value to randomize the starting PAT version number after a reboot.
Range: 0 – 15
Insert a value to randomize the starting PMT version number after a reboot.
Range: 0 – 15
