Description
Alpha mode to color key convert
Samples with alpha component below 80 (hex) are replaced with
values defined in CKEY_COMP 1-3.
Color keying replace mode
Color key mask component 1
Defines bits of color component that are compared against color key
value setting to key sample.
Color key mask component 2
Defines bits of color component that are compared against color key
value setting to key sample.
Color key mask component 3
Defines bits of color component that are compared against color key
value setting to key sample.
Alpha value
Defines the alpha value to be used for keyed samples.
Color key component 1
Defines value of color key for component 1 (red or Y).
Color key component 2
Defines value of color key for component 2 (green or U).
Color key component 3
Defines value of color key for component 3 (blue or V).
Base address mode
Output format endian mode
00 = no alpha manipulation
01 = reserved
10 = reserved
11 = alpha to color key convert
00 = no color component manipulation
01 = replace keyed color components with black (10, 10, 10)
10 = replace keyed color components with gray (80, 80, 80)
11 = replace keyed color components with last non-key value
00 = single set (e.g. progressive video source)
base 1-3 according to number of planes (plane 1-3)
01 = alternate sets each line (e.g. anti-flicker mode)
base 1-3, first line out, etc. (plane 1-3)
base 4-6, second line out, etc. (plane 1-3)
1x = reserved
0: same as system endian mode
1: opposite of system endian mode
