It's purpose is to separate Color Signal from the Black and White signal and send both signals to the proper circuits for further processing....
All color TV signals "Blend" the Color and B/W together, BUT it's better if the two never "Blend"....That's why S-Vid connections were so hot years ago...Keeps intermodultion of the signals occurring, which results in less distortion.....
Well the 3D-YC circuit was a genius circuit as it was designed to TRULY SEPARATE the 2 signals with ACTIVE DIGITAL FILTERING....Not passive signal filtering which never removed ALL the color from the Black and White signal....You ended up with color "remnants" distorting the Black/White signal....
The Black/White content of the picture produces the DETAIL, The Brightness, the Contrast and the Synchronizing parts of the picture....so the color would mess up the DETAIL especially....
The 3D-YC Digital filter is the BEST filter above all other designs.....
It intelligently removes color from black/white by storing the previous line and the present line, and the upcoming line by buffering it...it removes the "Present- line" coloring by looking at the previous and the upcoming lines, determining what colors are in both, and removing the color in the present line with that information.....
Sorry that's as detailed as you need to know....all other info is based on Phase relationships of the color signal and that's pretty DEEP stuff....

RE:
What is a 3DYC Digital Comb Filter on an LCD HDTV, and what does it do?

The previous answer is pretty good, but not very accurate.
3D Comb filters work actually in 3 Dimensions (not colors).
These are X, and Y (horiz, vertical) within a frame and Time (filtering across frames)
In a 2D filter all processing is done within the same frame, but in 3D filters you also take into account what happened in the previous frame. 3D filters are also called motion adaptive filters, since you decide on whether you apply 3D filtering based on the amount of motion. For most TVs, 3D comb filtering is almost a given.

Thanks for your details.
i have doubt in viewing 3d videos in same 3dy/c HD TV SET.
Can we see Active shutter glass 3d video through stereoscopic player connected by laptop?
