In systems with dynamic behavior on the input, it is recommended to create a rule for all PIDs to
be added to the output if a fixed and dedicated line-up is required. This way, it is easier for this
system to decide what action to take when the input changes. In some cases, a lack of
definition will force the system to temporarily stop PIDs.
For example, a TTX PID in Passthrough mode changes on the input to a PID value already
assigned manually on the output. In this case, the PSI system will stop the signaling of that TTX
PID until the system has decided what to do with the TTX PID – i.e. automatically map it to a
new, free PID value.
In an output service, if a video PID with PCR is stopped then this will be stopped
on the output, but the PCR can be extracted and output. This can be used in
cases where you would like to create a radio service using a PCR from a
signaled video PID in the service.
7.3.8.2 Component multiplexing
With Service component multiplexing it is possible to add an Audio, Teletext, DVB
Subtitle, AIT, HbbTV-carousels or private component from another input source to an
outgoing service. This PID will be multiplexed into the outgoing stream and signalled in
the PMT of the service.
Adding components to an outgoing service is done on the Components Mapping section
by clicking the plus button. This will show a selection dialog where all valid Audio,
Teletext, DVB Subtitle, AIT, HbbTV-carousels or private PID that can be selected for
output.
