The same methods are used to decimate the color difference
outputs. Simple decimation by removing every other sample
of color information may yield unsatisfactory results due to
aliasing. This is a problem because the color difference sig-
nals have not been transformed with the higher-bandwidth
luminance signals and therefore have higher bandwidths than
they had before the transform. The best performance is
obtained by using a precise low-pass (half-band) decimation
filter such as the TMC2242B to remove aliasing components.
See Figure 11.
The TMC2242B is a bi-directional, selectable rate filter/
interpolator/decimator.
