We are using ADV7182 chip to receive PAL/NTSC composite video. When we give NTSC input we are getting upper 12 lines extra (black line) when we check the resolution its shows that 720x253 and 720 x254 instead of 720x240. Please can you check and let me know the reason for this.
I have attached the ADV7182 configuration files with this mail.
Thanks & Regards
