Argument
No arguments.
PHBDescription
PHB sets the upper-bound of the blue portion of the RGB value used for chroma key. The upper-bound of the color is determined by taking the color value that is desired (0-255) and adding a guardband value to take into account accuracy limitations of the hardware. The upper-bound limit is still 255 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 blue portion of the above RGB values plus the guard- band.
PHC
Description
PHC adjusts the horizontal coarse setting.
Argument
The allowable range is 0-255 base10. The factory default is 128.
PHF
Description
PHF adjusts the horizontal fi ne setting.
Argument
The allowable range is 0-248 base10. The factory default is 119.
PHGDescription
PHG sets the upper-bound of the green portion of the RGB value used for chroma key. The upper-bound of the color is determined by taking the color value that is desired (0-255) and adding a guardband value to take into account accuracy limitations of the hardware. The upper-bound limit is still 255 even with the guardband.
