I am interfacing adv7180 video decoder with video encoder adv7391 through FPGA, i configured decoder and encoder as per attached doc1. and connected all the signal coming from decoder to encoder through FPGA.I applied PAL camera output to video decoder.the problem is
1. sfl signal generated by decoder is not correct.check attachment doc2 for sfl waveform captured in FPGA.
2. output connect to encoder(display) is distorted.
i would like to know where is the problem,how to check decoder output is correct or not?
