Building Type 1, Type 2, and Type 3 Commands 209

4 Set the Jump To menu to First Play PGC.

The Type 1 command appears in the Command List, indicating that the button is linked

to the First PGC in the System Space (JumpSSFP_DOM). In the Scenario Editor, the Btns

ﬂag for the menu PGC turns yellow.

Building a Type 2 Command

The following procedure documents how to build a Type 2 command in the Simulation

window (a Compare command will be added to the Type 1 command created in “Building a

Type 1 Command” on page 207).

A Compare command compares one navigation parameter value to another, such as:

If the GPRM7 value equals the SPRM9 value, play Title 3.

A Compare command can also compare a navigation parameter to a speciﬁed value, such as:

If the SPRM13 value is greater than 6, Jump to PGC in System Space.

In either case, if the comparison is true, the DVD player performs the instruction. If the

comparison is false, the DVD player ignores the instruction.

Note: SetSystem and Set are classiﬁed as Type 2 commands even when they are not

combined with a Link or Compare command.
