Apple DVD Studio Pro 4 - Manual (Page 611)

• Audio Player Config: Use to set up a condition based on the DVD player’s audio
configuration—PCM, AC-3, and MPEG (SPRM 15). The state requires a decimal number
entry.
• GPRM 0 - 7: Use to set up a condition based on the values stored in one of the eight
GPRM locations. The values must first be placed into the GPRM by a separate script
that you have run. The state requires a decimal number entry.
Note: Display conditions can only use full 16-bit GPRMs.
See Scripting Overview for details on scripts, GPRMs, and SPRMs.
Conditional Relationships
There are seven conditional relationships for you to choose from when setting up your
display condition.
• = (equal): The element and state are exactly equal. For example, if you choose the
Player Region Code element, a state of 1-USA, and the “equal” relationship, you can
only play the track if the DVD player is set for region 1-USA.
• != (not equal): The element and state are not exactly equal. For example, if you choose
the Audio Language element, a state of French, and the “not equal” relationship, you
can play the track as long as the DVD player is not set for French.
• > = (greater or equal): The element is either greater than the state, or they are equal.
For example, if you choose the Parental Level element, a state of PG-13, and “greater
or equal,” you can play the track as long as the DVD player is set to PG-13 or higher (R
or NC-17).
• > (greater): The element is greater than the state. For example, if you choose the Audio
Stream Number element, a state of 2, and “greater,” you can play the track as long as
one of the two first audio streams is not selected.
• <= (smaller or equal): The element is either less than the state, or they are equal. For
example, if you choose the Last Track Played element, set the state to 12, and “smaller
or equal,” you can play this track as long as the previous track is from 1 to 12.
• < (smaller): The element is less than the state. For example, if you choose the Subtitle
Stream Number element, set the state to 4, and “smaller,” you can play this track as
long as subtitle streams 1 through 3 are selected.
