APPENDIX

default for PIP 4 = Sand (R:255,G:204,B:153)

default guardband = 50

The default for this command is the green portion of the above RGB values minus the guardband.

PLR

Description

PLR sets the lower-bound of the red portion of the RGB value used for chroma key. The lower-bound of the color is determined by taking the color value that is desired (0-255) and subtracting a guardband value to take into account accuracy limitations of the hard- ware. The lower-bound limit is still “0” even with the guardband.

Argument

The allowable range is 0-255 base10. The default value is dependent on which one of the PIPs being addressed. There are currently four chroma key colors used as default colors they are the following:

default for PIP 1 = Cyan (R:0,G:255,B:255)

default for PIP 2 = Magenta (R:255,G:0,B:255)

default for PIP 3 = Chartreuse (R:135,G:255,B:0)

default for PIP 4 = Sand (R:255,G:204,B:153)

default guardband = 50

The default for this command is the red portion of the above RGB values minus the guard- band.

PON

Description

PON toggles the RGB PIP ON/OFF.

Argument

Provide a “1” to turn ON and a “0” to turn OFF.

PPC

Description

PPC changes the size of the RGB PIP. The aspect ratio of the native glass (4:3) is maintained by the display.

Argument

The allowable range is 10-800 base10. Providing a value of 800 makes the PIP fi ll the display.
