CBENB
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.

SYMP
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 BT656”compatible data at
MPEG port
0 = YC
B
C
R
-to-RGB dematrix is active; default state after reset
1 = YC
B
C
R
-to-RGB dematrix is bypassed
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 2’s 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 2’s 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:
