The chrominance resampling from 8-bpc or 10-bpc to 12-bit color components is always performed using filtering (the scaler unit filter). Chrominance resampling and rescaling can be combined to support native rescaling of YUV formats.
The usage of the scaler unit for resampling the chrominance of YUV420 and YUV422 is shown in Figure 12-337 and Figure 12-338, respectively. The settings of the scaler unit to perform chrominance resampling are described in Section 12.6.3.8.5, DISPC VID Scaler Unit.
The vertical scaler is not a mandatory block for resampling the chrominance of YUV422 data, as shown in Figure 12-338.
Using the filter it is possible to re-sample the chrominance from either MPEG1 or MPEG2 sub-sampled chroma source.
