The values shown in Table 66 are optimized for the EBU colour bar (100% white and 75% chrominance amplitude)
signal. The decoder output signal level fulfils the CCIR 601 specification. The input of 100% colour bar level is possible,
but the signal (white) peak function reduces the digital luminance output. With a different set-up it is possible to proceed
100% colour bar signal without luminance colour bar reduction. The method is to modify the AD input range for this input
level by reducing the gain reference value (SBOT > 06h) and adjusting the digital Y output level with contrast and
brightness control.
