Our customer uses ADV7393 at input of BT656 and output of NTSC.
Register 0x30 is default setting.
0X30 = 0
0：External HSYNC, VSYNC and field inputs
1：Embedded EAV/SAV codes
ADV7393 output video signal (NTSC) correctively when H and V input signal is not connected.
1. Does ADV7393 determine Timing of H and V from input of BT656 when H and V signal is not connected and 0x30= 0?
2. If we need any other settings, please let me know your advice.
