I understand video signal in the ADV728x-M goes like
NTSC in --> BT656 --> CSI2-Tx --> D-Phy
and then fed to a back end Processor w/CSI2-Rx.
*Timing information(V/H/F) embedded on BT656 transffered to CSI2 format.
Can you exlpain how the back end processor to know field bit information because this is not mentioned in ADV728x docs? I'm afraid this might be specific on CSI2 protocol itself..but I'd like to have your advise on this.
