Operating the Multiplexer using nCompass Control
4.10 Set up Single Program Clock Reference (Remultiplexed
Input)
4.10.1 Incoming Transport Stream
Unless the incoming transport stream has exactly the same 27 MHz reference as
the local Multiplexer, Single-PCR operation is only supported for Ericsson Encoder-
based services. When operating in this mode, the Encoders and Multiplexer/s must
be frequency locked to the same studio clock reference source.
4.10.2 Mixed PCR System
The PCR PIDs of the remote input can be remultiplexed (if it has a separate PCR)
or, if the input is a component, it will be removed with its embedded PCR. This is
termed a Mixed PCR system.
4.11 Clone a TS in the Clear
This configuration produces a cloned output in addition to the main scrambled
output. This could be used for local monitoring purposes.
The process has three steps:
1. Add an output device to the Physical Map
2. Configure the Multiplexer to produce the Clear stream
3. Connect the Multiplexer to the Output device.
Figure 4.5 Clone a TS in the Clear
An output is a data stream leaving the system. Each output needs to be defined and
labeled.
Note: See the nCompass Control User Guide for further information.
