Figure 3-238. PS audio extractor parameters
Parameters
The parameters you set here act as filters for the component extraction,
that is, the Electra VS will extract the component(s) it finds that matches
the parameters you defined.
For this processing component, you must set the following parameters:
 Maximum number of audio channels : if the expected audio if
5.1, set this value to 6 , if it is stereo, set this value to 2 , and if it is mono,
set this value to 1 .
 Stream Id : Stream identifier. If set to First component , the Electra VS
will extract the first component it finds that matches the parameters
you defined. If set to
All , the Electra VS will extract the all components
it finds that matches the parameters you defined.
 Codec : AAC , MPEG-1 layer 2 , AC3 or Any . If set to Any , the codec is
automatically detected.

Language : leave to Any if you do not want to specify the language of
the audio component, or use the ISO codes
1
to specify it (for instance,
enter eng for English, spa for Spanish, etc.).
 Clock management : if set to Convert to device internal clock
(default value), then the input clock is converted to the device clock. If
set to
Keep input clock , then the input clock is kept. When you want to
multiplex components from different input programs (to create a
mosaic for instance), the clocks shall be converted to the device clock.
