28) DISPLAY CONTROL

 

LD/CD

 

 

 

 

Function:

Character display is turned ON/OFF.

 

 

Format:

Integer

D S

 

 

 

 

Explanation:

Contents of the Display Control Register are displayed.

 

 

 

The initial value of the register is 0 and the display switch is OFF.

 

 

 

When it is turned on, (1DS) the chapter number, frame number or

 

 

 

time number and the user’s area can be displayed if an LD is

 

 

 

playing and if chapters are encoded on the disc. If a CD is playing

 

 

 

track, index, time numbers and the user’s area can be displayed.

 

 

 

The display lines are determined by the Register A setting. At

 

 

 

power-on, the default setting for Register A is 3RA. This makes

 

 

 

available the frame or time number on LDs and chapter numbers if

 

 

 

they are encoded on the disc. If a CD is playing, track and time are

 

 

 

available. The actual items to be displayed are determined by the

 

 

 

contents of Register A. See page 4-39 for details about Register A.
