INPUT DATA FORMAT
Input Digital Level
The content conforms to CCIR601 (ITU-601).
For chrominance input Cb and Cr, 2’s complement and offset binary formats are available by
setting of internal registers.
Input values outside the specified range are limited by internal clipping processing.
The valid input levels of luminance signal and chrominance signal are shown below.
Basic Pixel Sampling Ratio
4:2:2 and 4:1:1 sampling are supported. An internal register can control the sampling ratio.
