ABSTRACT:
Herein described is a system and method for improving the appearance of video by generating an improved 4:2:2 chroma. The system comprises a 4:2:2 to 4:2:0 chroma regenerator that regenerates 4:2:0 chroma given a received 4:2:2 chroma, and a 4:2:0 to 4:2:2 chroma generator that weaves and interpolates the regenerated 4:2:0 chroma to yield an adjusted 4:2:2 chroma. The system further comprises a blending system used for blending the adjusted 4:2:2 chroma with the received 4:2:2 chroma based on a control input provided by a motion indication signal. The method comprises regenerating a 4:2:0 chroma from a received 4:2:2 chroma using an algorithm. The method further comprises generating an adjusted 4:2:2 chroma using the regenerated 4:2:0 chroma using another algorithm. The method further comprises blending the adjusted 4:2:2 chroma with the received 4:2:2 chroma to generate an improved 4:2:2 chroma.
