BRI[7:0] Brightness Adjust (SDP), Address 0x0A, [7:0]
This register controls the brightness of the video signal through
the SDP core.
Table 50. BRI Function
BRI[7:0]
Description (Adjust Brightness of the Picture)
0x00*
Offset of the luma channel = 0IRE.
0x7F
Offset of the luma channel = 100IRE.
0xFF
Offset of the luma channel = –100IRE.
*Default value.
Rev. A | Page 26 of 104
HUE[7:0] Hue Adjust (SDP), Address 0x0B, [7:0]
This register contains the value for the color hue adjustment.
HUE[7:0] has a range of ±90°, with 0x00 equivalent to an
adjustment of 0°. The resolution of HUE[7:0] is 1 bit = 0.7°.
The hue adjustment value is fed into the AM color
demodulation block. Therefore, it only applies to video signals
that contain chroma information in the form of an AM
modulated carrier (CVBS or Y/C in PAL or NTSC). It does not
affect SECAM and does not work on component video inputs
(YPrPb).
Table 51. HUE Function
HUE[7:0]
Description
(Adjust Hue of the Picture)
0x00*
Phase of the chroma signal = 0°.
0x7F
Phase of the chroma signal = –90°.
0xFF
Phase of the chroma signal = +90°.
*Default value.
DEF_Y[5:0] Default Value Y (SDP), Address 0x0C, [7:2]
In cases where the ADV7189 loses lock on the incoming video
signal or where there is no input signal, the DEF_Y[5:0] register
allows the user to specify a default luma value to be output.
This value is used under the following conditions:
If DEF_VAL_AUTO_EN bit is set to high and the
ADV7189 lost lock to the input video signal. This is the
intended mode of operation (automatic mode).
The DEF_VAL_EN bit is set, regardless of the lock status of
the video decoder.
This is a forced mode that may be useful during
configuration.
The DEF_Y[5:0] values define the 6 MSBs of the output video.
The remaining LSBs are padded with 0s. (For example, in 10-bit
mode, the output is Y[9:0] = {DEF_Y[5:0], 0, 0, 0, 0}.)
Table 52. DEF_Y Function
DEF_Y[5:0]
0x36 (Blue)*
*Default value.
Description
Default value of Y.
DEF_C[7:0] Default Value C (SDP), Address 0x0D, [7:0]
The DEF_C[7:0] register complements the DEF_Y[5:0] value. It
defines the 4 MSBs of Cr and Cb values to be output if
The DEF_VAL_AUTO_EN bit is set to high and the
ADV7189 can’t lock to the input video (automatic mode).
DEF_VAL_EN bit is set to high (forced output).
The data that is finally output from the ADV7189 for the
chroma side is Cr[7:0] = {DEF_C[7:4], 0, 0, 0, 0}, Cb[7:0] =
{DEF_C[3:0], 0, 0, 0, 0}.
In cases of full 10-bit output mode, two extra LSBs of value 00
are appended.
Table 53. DEF_C Function
DEF_C[7:0]
Description
0x7C (blue)*
Default values for Cr and Cb.
*Default value.
DEF_VAL_EN Default Value Enable (SDP),
Address 0x0C, [0]
This bit forces the use of the default values for Y, Cr, and Cb.
Refer to the descriptions for DEF_Y and DEF_C for additional
information. The decoder also outputs a stable 27 MHz clock,
HS, and VS in this mode.
Table 54. DEF_VAL_EN Function
DEF_VAL_EN
Description
0*
Don't force the use of default Y, Cr, and Cb
values. Output colors dependent on
DEF_VAL_AUTO_EN.
1
Always use default Y, Cr, and Cb values.
Override picture data even if the video decoder
is locked.
*Default value.
DEF_VAL_AUTO_EN Default Value Automatic Enable
(SDP), Address 0x0C, [1]
This bit enables the automatic usage of the default values for Y,
Cr, and Cb in cases where the ADV7189 cannot lock to the
video signal.
Table 55. DEF_VAL_AUTO_EN Function
DEF_VAL_AUTO_EN
Description
0
Don't use default Y, Cr, and Cb values. If
unlocked, output noise.
1*
Use default Y, Cr, and Cb values when
decoder loses lock.
*Default value.
