ADV7183B
SD_SAT_Cr[7:0] SD Saturation Cr Channel, Address
0xE4[7:0]
This register allows the user to control the gain of the Cr channel
only. The user can adjust the saturation of the picture.
Table 24. SD_SAT_Cr Function
SD_SAT_Cr[7:0]
Description
0x80 (default)
Gain on Cr channel = 0 dB
0x00
Gain on Cb channel = 42 dB
0xFF
Gain on Cb channel = +6 dB
SD_OFF_Cb[7:0] SD Offset Cb Channel,
Address 0xE1[7:0]
This register allows the user to select an offset for data on the
Cb channel only and adjust the hue of the picture. There is a
functional overlap with the Hue[7:0] register.
Table 25.SD_OFF_Cb Function
SD_OFF_Cb[7:0]
Description
0x80 (default)
0 offset applied to the Cb channel
0x00
312 mV offset applied to the Cb channel
0xFF
+312 mV offset applied to the Cb channel
SD_OFF_Cr[7:0] SD Offset Cr Channel, Address
0xE2[7:0]
This register allows the user to select an offset for data on the Cr
channel only and adjust the hue of the picture. There is a func-
tional overlap with the Hue[7:0] register.
Table 26. SD_OFF_Cr Function
SD_OFF_Cr[7:0]
Description
0x80 (default)
0 offset applied to the Cr channel
0x00
312 mV offset applied to the Cr channel
0xFF
+312 mV offset applied to the Cr channel
BRI[7:0] Brightness Adjust, Address 0x0A[7:0]
This register controls the brightness of the video signal. It
allows the user to adjust the brightness of the picture.
Table 27. BRI Function
BRI[7:0]
Description
0x00 (default)
Offset of the luma channel = 0IRE
0x7F
Offset of the luma channel = +100IRE
0xFF
Offset of the luma channel = –100IRE
Rev. B | Page 24 of 100
HUE[7:0] Hue Adjust, Address 0x0B[7:0]
This register contains the value for the color hue adjustment. It
allows the user to adjust the hue of the picture.
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 applies only 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 28. HUE Function
HUE[7:0]
Description
0x00 (default)
Phase of the chroma signal = 0°
0x7F
Phase of the chroma signal = –90°
0x80
Phase of the chroma signal = +90°
DEF_Y[5:0] Default Value Y, Address 0x0C[7:2]
If the ADV7183B loses lock on the incoming video signal or if
there is no input signal, the DEF_Y[5:0] bits allow the user to
specify a default luma value to be output. This value is used if
The DEF_VAL_AUTO_EN bit is set to high and the
ADV7183B 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 8-bit
mode, the output is Y[7:0] = {DEF_Y[5:0], 0, 0}.
DEF_Y[5:0] is 0x0D (blue) is the default value for Y.
Register 0x0C has a default value of 0x36.
DEF_C[7:0] Default Value C, 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
ADV7183B cannot lock to the input video (automatic
mode).
The DEF_VAL_EN bit is set to high (forced output).
The data that is finally output from the ADV7183B 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}.
DEF_C[7:0] is 0x7C (blue) is the default value for Cr and Cb.
