Hello all,

 

We input data 0 to ADV7171KSUZ.
Output NTSC waveform has been measured by oscilloscope.
Value of brightness signal after Back porch  is lower than value of back porch and front porch (0IRE).
We think that  brightness is higher value than 0IRE on NTSC specification.
Please let me know about the reason of above issue.
