3DYC, frame recursive noise reduction (3DNR), and time base correction (TBC) can be used simultaneously
or independently.

NOTE: The SDRAM configuration register must be programmed before enabling features that
require the SDRAM. Failure to do so will result in incorrect operation of the memory controller.
3DYC:
0 = Disable; the 2D adaptive 5-line comb filter is enabled (default)
1 = Enable
3DYC enhances 2D Y/C separation by utilizing temporal-based, or frame-based information. 3DYC
requires the use of the frame buffer memory and can be used simultaneously with 3DNR and TBC.
TBC:
00 = Disable (default)
01 = On
10 = Automatic selection
11 = Automatic selection
Line-based time correction corrects for horizontal phase errors encountered during video decoding up to
±80 pixels of error. TBC can be used simultaneously with 3DYC and 3DNR. TBC does not require external
memory.
Chrominance adaptive comb enable:
0 = Enable (default)
1 = Disable
This bit is effective on composite video only.
3DNR:
0 = Disable (default)
1 = Enable
Frame recursive noise reduction minimizes the amount of noise in interlaced CVBS, S-Video, or
component inputs. 3DNR requires the use of the frame buffer memory and can be used simultaneously
with 3DYC and TBC.
NOTE:Noise reduction can not be used on progressive inputs.
Automatic color gain control (ACGC) [1:0]:
00 = ACGC enabled (default)
01 = Reserved
10 = ACGC disabled, ACGC set to the nominal value
11 = ACGC frozen to the previously set value
