YDTO2 Read value range: 0 to 1
Luminance noise detection flag.
At NRDTON = 1, YDTO2 is set to “1” if YAVRO[6:0] > YAVR2[6:0] state continues in 4 frames.
YDTO2 is fixed to “0” in the case of YAVR2[6:0] = 7Fh.
CDTO2 Read value range: 0 to 1
Chrominance noise detection flag.
At NRDTON = 1, CDTO2 is set to “1” if CAVRO[6:0] > CAVR2[6:0] state continues in 4 frames.
CDTO2 is fixed to “0” in the case of CAVR2[6:0] = 7Fh.
YMAXO[4:0] Read value range: 0_0000 to 1_1111
Luminance noise level of 8 frames average (YNAMS = 0), or of 1 frame (YNAMS = 1), of the noise
maximum value of lines detected at NRDTON = 1.
Updated every frame. 3Fh is read out if the noise level exceeds 3Fh.
CMAXO[4:0] Read value range: 0_0000 to 1_1111
Chrominance noise level of 8 frames average (CNAMS = 0), or of 1 frame (CNAMS = 1), of the noise
maximum value of lines detected at NRDTON = 1.
Updated every frame. 3Fh is read out if the noise level exceeds 3Fh.
YBAVRO[6:0] Read value range: 000_0000 to 111_1111
Luminance noise level of 8 frames average (YNAMS = 0), or of 1 frame (YNAMS = 1), of luminance
base noise absolute value average of lines detected at NRDTON = 1
Updated every frame. 7Fh is read out if the noise level exceeds 7Fh.
YBAVRO[6:4] is an integral part and YBAVRO[3:0] is a decimal part.
CBAVRO[6:0] Read value range: 000_0000 to 111_1111
Chrominance noise level of 8 frames average (CNAMS = 0), or of 1 frame (CNAMS = 1), of
chrominance base noise absolute value average of lines detected at NRDTON = 1
Updated every frame. 7Fh is read out if the noise level exceeds 7Fh.
CBAVRO[6:4] is an integral part and CBAVRO[3:0] is a decimal part.
YBDTO Read value range: 0 to 1
Luminance base noise detection flag.
At NRDTON = 1, YBDTO is set to “1” if YBAVRO[6:0] > YAVR1[5:0] state continues in 4 frames.
CBDTO Read value range: 0 to 1
Chrominance base noise detection flag.
At NRDTON = 1, CBDTO is set to “1” if CBAVRO[6:0] > CAVR1[5:0] state continues in 4 frames.
