0 = data from input ports is encoded; default state after reset
1 = colour bar with fixed colours is encoded
These 2 bits are reserved; each must be set to a logic 0.
0 = horizontal and vertical trigger is taken from RCV2 and RCV1 respectively; default
state after reset
1 = horizontal and vertical trigger is decoded out of “ITU-R BT.656” compatible data at
MPEG port
0 = YC
1 = YC
0 = CVBS output signal is switched to CVBS DAC; default state after reset
1 = advanced composite sync is switched to CVBS DAC
0 = input data is twos complement from MPEG port fader input
1 = input data is straight binary from MPEG port fader input; default state after reset
0 = input data is twos complement from Video port fader input
1 = input data is straight binary from Video port fader input; default state after reset
Key colour 1 lower and upper limits for U, V and Y. If MPEG input signal is within the
limits of key colour 1 the incoming signals at the Video port and MPEG port are added
together according to the equation:
FADE1
Default value of all bytes after reset = 80H.
Key colour 2 lower and upper limits for U, V and Y. If MPEG input signal is within the
limits of key colour 2 the incoming signals at the Video port and MPEG port are added
together according to the equation:
FADE2
Default value of all bytes after reset = 80H.
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
