TS Audio Packetizer
Description
The TS Audio Packetizer processing component encapsulates an
audio elementary stream into MPEG-2 transport packets. These packets
can then be sent to a TS multiplexer.

Parameters
For this processing component, you must set the following parameters:
 PCR generation : select the PCR generation mode:
 Add on component : add PCR on the audio component.
 Create independent PCR PID : an independent PID for the PCR is
created. Choose this mode for ISDB-Tb programs. In this case,
you must indicate the PID value in the
TS multiplexer
processing component, in the Input tab, in the PCR PID field.
See section
’TS Multiplexer’ on page 327.
 None : no PCR is added.
 AAC encapsulation (useful only for an AAC component): choose
whether the AAC audio should be encapsulated with
 LOAS/LATM header (mandatory for ISDB-Tb)
 ADTS header (good choice otherwise)
 Audio encapsulation mode : choose whether the number of
frames per PES should be
fixed number of frames per PES or variable
number of frames per PES
.
 fixed number of frames per PES : the number of frames per PES
is fixed. Set the
Number of frames per PES .
 variable number of frames per PES: The number of frames per
PES is variable requiring less bandwidth. However, some
receivers do not support this feature.
