How to read out H/V polarity for SOG ( sync-on-green) with ADV7850

Hi,

  Please check with below registers to read out the H/V polarity,

0xB5[3] and 0x4F[3] are used to read the Hsync Polarity of channel 1 and channel 2 SSPD.
0xB5[5] and 0x4F[5] are used to read the Vsync Polarity of channel 1 and channel 2 SSPD.

Thanks,

Hi Poornima,

These two registers are for the H/V Sync or CSync, but they do not work for the SOG (Sync-On-Green) case. SOG uses embedded Sync, and its polarities cannot be read out through these two registers.

Thanks,

Hi,

  I don't think there is separate Hsync/Vsync register which is available for SOG Since you would need the sync separator circuit if you want H/V syncs.
