BIT
SYMBOL
FADE1[5:0]
DESCRIPTION
7 to 6
5 to 0
These 2 bits are reserved; each must be set to logic 0.
These 6 bits form factor FADE1 which determines the ratio between the MPEG and
video input signal in the resulting video data stream if the key colour 1 is detected in the
MPEG input signal.
FADE1 = 00H: 100% MPEG, 0% video
FADE1 = 3FH: 100% video, 0% MPEG; this is the default value after reset

0 = fader operates in normal mode; default state after reset
1 = the entire video input stream is faded with the colour stored in the LUT
(subaddresses 51H to 53H) regardless of the MPEG input signal. The colour keys are
disabled.
0 = fader operates in normal mode; default state after reset
1 = the entire MPEG input stream is faded with the colour stored in the LUT
(subaddresses 51H to 53H) regardless of the video input signal. The colour keys are
disabled.
These 6 bits form factor FADE2 which determines the ratio between the LUT colour
values (subaddresses 51H to 53H) and the video input signal in the resulting video data
stream if the key colour 2 is detected in the MPEG input signal.
FADE2 = 00H: 100% LUT colour, 0% video
FADE2 = 3FH: 100% video, 0% LUT colour; this is the default value after reset

DESCRIPTION
7 to 6
5 to 0
These 2 bits are reserved; each must be a logic 0.
These 6 bits form factor FADE3 which determines the ratio between the MPEG and
video input signal in the resulting video data stream if neither the key colour 1 nor the
key colour 2 is detected in the MPEG input signal.
FADE3 = 00H: 100% MPEG, 0% video
FADE3 = 3FH: 100% video, 0% MPEG; this is the default value after reset
