Hi Hyun,
Unfortunately we still have a difficulties to extract WSS signaling, while using TVP5150 chip.
We are doing the registers initialization, as described above, on system init.
We are performing C6h register polling just after it and get 40h value (FIFO empty, WSS is not available).
We are using two different CVBS sources with WSS signalling.
Do you have any clue about the possible root of the problem?
Best Regards.
Boris Barak.
