From ADV7182 datasheet, its known that Chip supports auto-detect for PAL or NTSC input.We are seeing when we give NTSC input we are getting resolution as 720x254(filed 0) and 720x253(filed 1). It should be 720x240(filed 0) and 720x243(filed 1). and we are displaying incoming Input on TV.When we give PAL input , we are getting proper display and when we give NTSC input, we are getting first few black color line (approximately 10-15 line). I have attached the configuration file. Can you please tell me the reason for the same.
Thanks & Regards
