    Hi,

    Does anyone here know what the proper formula would be as to converting chroma/luma values to R-Y and B-Y???

    For example:
    Texas Instruments TMS9918A Medium Green
    Y' (luminance) = 0.53
    A' (amplitude) = 0.27
    Phase angle = 237
    I = -0.11
    Q = -0.24
    R-Y = -0.25
    B-Y = -0.29

    Bolded entries are what I need help for conversion to and from R-Y and B-Y.

    Thank you,
