SPRM 11: Player Audio Mixing Mode for Karaoke
Karaoke-capable DVD players can blend several audio streams together.
Note: Refer to SPRM 15 to identify whether or not a DVD player is karaoke-capable.
The primary stream is usually a music-only track in stereo (L and R). It is usually stream
number 1 or 2. To those streams you can mix a melody stream (M) or vocal streams (V1
and V2). The melody stream and the vocal streams are usually stream numbers 3, 4, and
5. The values of SPRM 11 are listed in the table below:
