Abstract:
1. A method of generating an improved 4:2:2 chroma comprising: receiving a 4:2:2 chroma; inputting said 4:2:2 chroma into a 4:2:2 to 4:2:0 chroma regenerator; selecting an algorithm to be used by said 4:2:2 to 4:2:0 chroma regenerator; using said algorithm to regenerate 4:2:0 chroma; weaving pixels from top and bottom fields of said 4:2:0 chroma to generate a 4:2:0 chroma frame; interpolating values provided by said 4:2:0 chroma frame to generate an adjusted 4:2:2 chroma; inputting said adjusted 4:2:2 chroma and said 4:2:2 chroma into a blending system used for blending two inputs; determining a first amount of said adjusted 4:2:2 chroma and a second amount of said 4:2:2 chroma for said blending; and adding said first and second amounts to generate an improved 4:2:2 chroma.
