About how digital audio formats are output
Note
• Depending on the disc, the number of channels may differ.
• Depending on the connected HDMI device, the HDMI output audio and number of channels may differ.
• Three types of audio are recorded on BD video discs.
– Primary audio: The main sound.
– Secondary audio: Additional sound added supplementarily, such as comments by directors, actors, etc.
– Interactive audio: Sounds such as clicks heard when operations are performed. The interactive audio differs
from disc to disc.

Method of
conversion
Only the primary audio (the
main sound for movies, etc.) is
output. The secondary audio
and interactive audio are not
output.
The primary audio, secondary
audio and interactive audio are
converted into PCM audio and
output simultaneously.
The primary audio, secondary
audio and interactive audio are
converted into PCM audio then
converted again into Dolby
Digital audio or DTS audio and
output simultaneously.
