New Color Encoding Method And Rgb Primaries For Ultrahigh Definition Television (Uhdtv)

The present study introduces a new RGB-primary set and a new color encoding method suitable for Ultrahigh-Definition TV (UHDTV) that is considered as one of next-generation TV systems. The new RGB primaries for UHDTV were proposed by taking into account real surface colors and the colorimetric characteristics of flat panel displays such as LCD and AMOLED. The new color encoding method was developed to enable luminance and chrominance information to be almost accurately separated in the attempt to solve the drawback that Recommendation ITU-R BT.709 has. The new luma and color-difference signals generated by the newly derived encoding scheme were demonstrated to have insignificant crosstalk. It was also proved that this fact could contribute to improving image quality after subsampling color difference components and to increasing efficiency in the image compression process.
