    • Methods and systems for 2D comb filtering of a PAL video signal are provided. The method may comprise generating a plurality of interpolated pixels for corresponding video samples in non-adjacent pixel lines for a video frame. At least one direction of least bandwidth may be determined among the video samples and the interpolated pixels. The method may blend combing in the determined direction of least bandwidth. A plurality of interpolated pixels for corresponding video samples may be generated in a first pixel line of the video frame. The plurality of interpolated pixels in the first pixel line may be shifted, so that each of the plurality of interpolated pixels in the first pixel line is one quarter cycle phase-shifted from a corresponding adjacent pixel in the first pixel line.

    • Methods and systems for time constant for a 3D comb filter of a video signal are provided. Aspects of the method may include assigning a weight to a 3D comb mesh value. Combing may be blended according to the assigned weight of the 3D comb mesh value. The weighted 3D comb mesh value may be accumulated in order to generate accumulated mesh value. If the accumulated mesh value exceeds a saturation value, the accumulated mesh value may be reduced to the saturation value. If the 3D comb mesh value is smaller than a first threshold value, the accumulated mesh value may be reset to zero. A multiplier may be generated according to the accumulated mesh value. If the accumulated mesh value is between a second threshold value and a third threshold value, the multiplier may be blended.
