Formulation of the YUV 422 Video Component Set
The C300 Mark II can alternatively be switched to originate a Luma Y and two Chroma Cr and
Cb 4:2:2 component set at a 10-bit depth and which can be selected to operate at all
international picture capture rates up to 60 fps.

The technical advantages of the Oversampling HD Processing for the RGB 4:4:4 and YCrCb
4:2:2 component sets are significant and can be summarized as follows:
4:2:2 component sets are significant and can be summarized as follows:
•
Luma & Chroma Resolution is improved
– Improved control of H & V sampling sidebands and extension of optical low pass filter
•
Luma aliasing is reduced
– Sampling sideband control and pre-filtering
•
Luma noise is reduced
– The upsampling process spreads the total noise power over a wider frequency range.
The subsequent filtering and downsampling reduce the noise power and imparts a finer
grained appearance to the output noise
grained appearance to the output noise
•
False Color Moire is reduced
– By special False Color Suppression following structuring of RGB HD frames
