TS Output Constant Bit rate – Specifies the output transport stream bit rate
(Mbps) when configured for Constant Bit Rate mode. This may be configured up
to 200 Mbps. The output Transport Stream will be extended with NULL packets
to ensure this bit rate on the output. A Filter Output Overflow alarm will be raised
if the output requires a higher bit rate to be played out properly.
Insert Nulls on Failure – Checking this box will ensure that a constant bit rate is
maintained even if the source Transport Stream is unlocked.
Over Rate Protection – In CBR mode the output TS bit rate may not be
sufficient to allow for the maximum instantaneous bit rate of the services
selected for filtering. This can especially be a problem in Stat MUX systems
where each service within a multi-service transport stream may continuously
vary its bit rate. To handle this, Over Rate Protection allows the peak packets to
be passed rather than clipped by to maintain the constant bit rate on the output
Transport Stream.
Service Splitting – Enables service splitting on the IP output. Service splitting
can be configured on Service Split tab. Refer to section 3.19.5, Service Splitting.
Remove CA descriptors – Removes the CA descriptors from the filtered output
Transport Stream.
This feature is only effective when the TS Feed setting on the Output Tab is set
to Descrambled and when the Service Filter Mode is configured to MULTI
SERVICE or SINGLE SERVICE (these modes are exposed depending on
license options enabled on the IRD). Internally in the RX8000, the Transport
Stream output from Service Filtering module is routed to the Service Splitting
module so services selected for Service Splitting will be affected.
It only supports stripping out CA descriptors for one service only, i.e. one PMT.
It does not support multiple services.
If enabled, will strip out the CA descriptors from the PMT of the service selected
for service filtering on the ASI and IP output being descrambled:
For MPTS, the Remove CA Descriptors feature will strip out the CA
-
descriptors from the PMT for the single service selected for descrambling
and decode. Descrambled services that are not selected for decode shall
not have their associated PMTs regenerated and shall remain unaffected.
i.e. If no service is selected for decode, then no CA descriptors are removed.
For SPTS, the Remove CA Descriptors feature will strip out the CA
-
descriptors from the PMT for the single service selected for descrambling
regardless of whether it is selected for decode or not, i.e. where there is only
one service in the Transport Stream being descrambled, it will always have
CA descriptors removed when this feature is enabled.
The Remove CA Descriptors feature will not modify the CAT and do not
remove any components listed in the CA descriptors removed and therefore it is
possible that these components will become ghost PIDs on the output transport
stream.
