About Karaoke
When creating a Karaoke title, audio assets must be encoded in the Dolby Digital (AC-3)
audio format with the Bit Stream mode set to Karaoke. For information on the Dolby Digital
(AC-3) encoding parameters, see Appendix B, “AC-3 Encoding.”
Karaoke titles can use multi-channel audio in which every channel is assigned to an
instrument or vocal guideline. This means that the left and right channels can contain only
the instrumental accompaniment, with the guide melody and backing vocals on the other
channels. Any of the channels can be activated in the stereo output of the DVD player, as
chosen by the singer.
Karaoke streams usually include the following channels, which are encoded to a single AC-3
file:
Note: Not all of these channels are required for Karaoke. Depending on the material, you
may find that only the L, R, and C channels are required.
