Figure 101. Stereo to Mono Down Mix
In Figure 102 , only the main stereo signal is available, with no surround
sound and no Mandarin or Cantonese versions. The table is used to up-mix
the stereo to the surround outputs, as well as down-mix the stereo program
to both the Mandarin and Cantonese mono outputs. The stereo-to-sur-
round up-mix is set up to provide signals from the left and right speakers
as well as create a center channel signal.
Figure 102. Stereo to All Output Groups Mix
Figure 103 shows an input table where there is only a surround audio
source available, and a stereo down-mix is created. The values used for the
down-mix create a Lo-Ro (Left only/Right only) mix for the stereo output,
while passing the Surround version with 1:1 mapping.
