Description
If enabled (by setting bit 31 to 1), the data fetched from memory will
be delayed until line number set here is reached, ie. the data pre-
fetch is disabled.
The number given here must be set to a value earlier in Y position
than LayerNStartY in 10E230 to prevent from layer underflow.
In non-interlaced mode :
In interlaced mode:
Brightness control bit for upper channel.
VCBM_U2B = 1 if brightness control is activated for the upper
channel.
Brightness control bit for middle channel.
VCBM_M2B = 1 if brightness control is activated for the middle
channel.
Brightness control bit for lower channel.
VCBM_L2B = 1 if brightness control is activated for the lower
channel.
Brightness Setting (Signed value ranging from -512 to 511 which is
equivalent to -100% to +100% brightness change for nominal
signals having a range from -256 to 255 with a contrast setting of
256)
Nominal value: 0
Brightness control is performed after e color space conversion in
associated with the contrast control.
Y‘‘ = Y‘ + VCBM_BRIGHTNESS if VCBM_U2B flag is raised.
Two’s complement to binary offset conversion for contrast control
(upper channel Y’/R’ = Y/R + VCBM_BLK_OFFSET)
Needs to be set in case the data format entering the VCBM is YUV
or RGB
Two’s complement to binary offset conversion for contrast control
(middle channel U/G)
Needs to be set in case the data format entering the VCBM is RGB
Two’s complement to binary offset conversion for contrast control
(lower channel V/B)
Needs to be set in case the data format entering the VCBM is RGB.
Back-end reverse offset (for two’s complement mentioned above)
control bit for upper channel.
(Yout/Rout = Yout/Rout - VCBM_BLK_OFFSET described below)
this value is relative to FRAME position. For example, if
LayerNStartY=100, a start fetch position of 98 is deemed earlier
position.
this value is relative to FIELD position. For example, if
LayerNStartY=100, a start fetch position of 52 is deemed one
line too late to start the fetch, because LayerNStartY=100 is
equivalent to field position 100/2=50. Therefore, a start fetch
positon of 48 is a proper one.
