2.2.4 Y/C Separation  
Y/C separation may be done using 3D or 2D adaptive 5-line (5-H delay) comb filters or chroma trap filter  
for both NTSC and PAL video standards as shown in Table 2-1. The comb filter can be selectively  
bypassed in the luma or chroma path. If the comb filter is bypassed in the luma path, then chroma notch  
filters are used. TI's patented adaptive comb filter algorithm reduces artifacts such as hanging dots at  
color boundaries. It detects and properly handles false colors in high-frequency luminance images such as  
a multiburst pattern or circle pattern.

2.2.5 3D Frame Recursive Noise Reduction  
The TI proprietary frame recursive noise reduction or 3DNR reduces the level of noise in CVBS, S-Video,  
or component inputs by comparing multiple frames of data and canceling out the resulting noise. The  
3DNR uses the same frame buffer memory used by the 3DYC. The 3DNR may function concurrently with  
3DYC.  
There are various modes of operation for the 3DNR and 3DYC:

2.2.6 Time Base Corrector  
The time base corrector monitors and corrects for horizontal PLL phase offsets up to ±80 pixels. This  
improves video decoder output quality by removing artifacts due to jittery horizontal syncs from broadcast  
stations. It also reduces line tearing during VCR trick modes such as fast forward and rewind. 3DYC,  
frame recursive noise reduction (3DNR), and time base correction (TBC) can be used simultaneously or  
independently. Because TBC does not require any external memory, it can be used in all configurations.  
2.2.7 IF Compensation  
Attenuation of higher frequencies from the tuners input characteristics or due to channels that are not  
correctly tuned can be corrected in the IF compensation block. This block can correct for uneven  
sidebands resulting in incorrect and uneven UV demodulation.
