Description Section
AC-3 DownMix *:
This item is only used if the Modulator setting
is set to ProLogic.
Stereo – If more than 2 audio channels are
present within the service, only the front right
and front left channels will be decoded.
LT-RT - If more than 2 audio channels are
present within the service, all channels are
decoded and downmixed to produce a stereo
compatible output.
Default = Stereo.
Note: * This option is only available if the AC-3
software option has been enabled on
the receiver.
----
The modulation of the audio depends both on the modulation used on the encoder
side, and on the decoder side. Table C.16 below lists what is output on the decoder,
in correlation to the modulator setting, and what is sent from the encoder.
Table C.16: Audio Modulation Results

No. 2 (R) 2 2 2 2 2 1
Single Channel (mono) 1 1 1 1 1 1
The Left output and Right output columns refer to the output at the left and right
audio connector, respectively. L and R refer to the content of the left and right audio
signal present in a stereo transport stream. 1 and 2 refers to the audio signals in
channel 1 and 2 respectively (the two mono signals present in the Dual Channel
audio PID), or 1 for a mono PID.
As seen from the table, Dual Channel PIDs will only provide both channels to the
user if modulation is set to transparent. This could for instance be very useful for a
two language service, where each language is sent as a mono component in a dual
channel PID. In both the stereo and mono configurations, a dual channel PID will
only provide one of the audio channels to the users.
This channel is selected to match the Aud Lang setting set up in the TV Service
Menu (see Table C.6). If the language setting does not match any of the two audio
components in the dual channel stream, the first one will be selected and decoded.
