6.2.10 Single-Service Filtering (RX8XXX/SWO/SING/SERVFILT)
This option is available for the RX8200, 8310, 8315, 8320 and 8330 Receivers.
This option filters a complete service from a Multiple Program Transport Stream
(MPTS) source and generates an Single Program Transport Stream (SPTS). When
the Output tab/Filter Group/Service Filter Mode/Single Service option is selected the
Filter column of the ServicePlus web page is enabled (see 5.2.10 Service Plus web
page description).
The service may be selected using the Service Program Number and the selection
will be retained during rebooting operations. All components of the service are
automatically filtered and available at the output. If a different service is selected, the
new components will replace those of the previously selected service.
If the RX8XXX can decrypt the source TS, the output of the filtered service may be
selected for descrambling.
The output bit rate, which is selected by the user, may be constant (by inserting
NULL packets) or variable (plus the increment due to the PSI SI insertion).
In Constant mode, if overrate protection is ticked the unit will not clip any services
which ‘over rate’ the selected bit rate. The unit also has the option to insert nulls on
failure. Both of these functions are available from the Output tab of the web control.
6.2.10.1 PSI/SI Insertion
When the input to the receiver is a DVB TS, the PAT and the SDT-Actual are
regenerated. The PMT regeneration is forced in case the PID is shared by more
than a PID. If this is not the case, PMTs will be passed through as will CATs, NIT-
Actual, TDT and TOT PIDs.
If the input to the receiver is an ATSC TS, only the PAT will be regenerated. THE
VCT PID will be passed through as will PMTs, CAT,TDT and TOT PIDs.
6.2.10.2 PID Remapping
This feature allows the filtering of a service from a Multiple Program Transport
Stream (MPTS) source and generates a custom Single Program Transport Stream
(SPTS) with components selected from those included in the service. These
components and the PMT PID can be remapped.
This service may be initiated by selecting the Output tab from the top of the current
web screen then selecting Filter Group>Service Filter Mode>REMAP. This enables
the REMAP column of the Serviceplus table. The required service is selected by
service program number and will be retained after rebooting. To select the
components which are to be filtered and remapped, the Details link should be
selected. Configuration is by component type or Input PID and relies on a best-
match algorithm where the most significant parameter is the component type. This
configuration is only available via the web interface.
