6.2.10Single-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.

6.2.10.1PSI/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.

6.2.10.2PID 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.
