For example, if the preset decoder is set for
3D Motion Threshold improves the video, select the
decoder to switch to a 2D adaptive decoder type. If increasing the threshold
improves the video, switch to the
Comb Filter
The comb filter is part of the 2D adaptive comb filter mode. It determines
what component of the video will be used to detect motion (Luma and
Chroma or just the Luma or Chroma portion of the video).
• – when set for both luminance and chrominance, the 2D
Luma + Chroma
adaptive decoder motion detector is controlled by both the luminance
and chrominance magnitude error.
• – in this mode, the 2D adaptive decoder motion selector is con-
Luma
trolled by only the luminance magnitude error in the video.
• – in this mode, the 2D adaptive decoder motion selector is con-
Chroma
trolled by only the chrominance magnitude error in the video.
Luma Level
The Luma Level control sets the magnitude error threshold for the Y or
luminance component of the video signal in the comb filter. The default
value is 56.
Chroma Level
The Chroma Level control sets the magnitude error threshold for the
chrominance portion of the video signal in the comb filter. The default
value is 56.
Luma Bandwidth
The Luma Bandwidth sets the frequency at which the comb filtering occurs.
It can be set for

Note Narrow or Wide bandwidth may be selected according to the chrominance
subcarrier frequency and chrominance bandwidth.
