I am using ADV 7401 to decode non standard video STANAG A 875 line scheme I have used the script provided in the discussion http://ez.analog.com/message/34616#34616 provided by rob.
But the status register reads(0x10) 6A which means that the 7401 has not locked to the input. I am using the ADV 7401 EVAL board and inputing the signals to Y Pb Pr connectors(P2 phono) ie Y on AIN6 and Pb Pr on AIN5 and AIN4 . Is this correct? Can you please suggest what is the problem?
