Audio Output Group Substitution
Typically, there is a one-to-one correspondence between audio input
groups and audio output groups as seen in
Figure 146 on page 234 . How-
ever, it is possible in some cases that an audio input group does not exist
for all audio output groups. In this case, it may be desirable to map one
input group to several output groups so that an audio signal exists on all
output groups.
Figure 147 shows an example of this where the “Main
Stereo” audio input group is mapped to the “Spanish” and “French” Mono
output groups since there are no Spanish and French audio input groups in
the source.
Figure 147. Audio Output Group Substitution
This scenario requires a down mix of the stereo input group to the mono
output groups. There is a known set of possible channel mappings and
down-mix, up-mix definitions for each of the available audio groups in
Maestro (mono, stereo, Dolby 5.1, Dolby 7.1 and Dolby E Pass Through).
These mappings are built into Maestro and require no configuration.
