DESCRIPTION

control of coring threshold; see Table 7

bandpass filter selection; see Table 8

peaking factor K; see Table 9

input format and filter control at 13.5 MHz data rate; see Table 10

choice modification; 0 = modification off; 1 = modification on.

DCTI timing range; see Table 11

DCTI gain factor; see Table 12

delay compensation of luminance signal; see Table 13

UV input data code; 0 = two’s complement; 1 = offset binary

blanking level on Y output; 0 = 16 LSB; 1 = 0 LSB

YUV input data solution; 0 = 7-bit data; 1 = 8-bit data

polarity of colour-difference output signals:

0 = normal polarity equal to input signal

1 = inverted polarity
