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 plus the guard- band.
PLB
Description
PLB sets the lower-bound of the blue 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 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 blue portion of the above RGB values minus the guardband.
PLG
Description
PLG sets the lower-bound of the green 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:
