Input Channels
Delete Channel
Deletes this channel's association with its current multiplexer function.
Function
Use this parameter to set the payload type and processing for this virtual channel.
Program
specifies the channel will carry a program to be multiplexed into the transport
stream of the referenced port.
Using the
PID
option, a single PID’s packets are inserted into the transport stream. The
packets will be remapped to the channel’s PID parameter and inserted into the selected
port's multiplex.
The following principles apply to the PID option:
When a PID is configured for individual extraction, its packets must not be routed
through any other VC on the interface.
No other VC should reference the PID for extraction from the multiplex, either
explicitly or implicitly; otherwise a
Transmit Channel Configuration Error
fault is
triggered.
This function supports “unusual” applications and might require application engineering
support to configure correctly. The VC carrying this single PID may be connected like a
normal multiplexer VC. Some destinations, such as decoders, are unlikely to process it
successfully, but the system does not prevent the connections. The most useful destination
is likely to be a multiplexer VC, whose function is set to insert a specific PID into a multiplex.
When a value of
0
is set in the
Program Number
field, the PID is not added to the PAT or
any PMT. A non-zero value forces the system to search for another channel on the same
interface that carries a matching program (its function should be {program, transrate}, and
the program number should match this channel's value). This channel's PID is then added as
a program element to the identified program, including the associated PMT entry. The
channel's configured stream type is used in the element's PMT entry. If no matching
program channel exists, the channel asserts an alarm configuration error fault.
The VC's interface is an external receiver with passthrough enabled. Some function values
consume limited internal resources. If any constraints are violated, the module will declare a
Configuration Error
fault.
