Hi, Icheng,

We've tested it ,here's our method and the result,

1.our method

in 'BOOL  APP_SplitterMergeEdids(UINT16 SegIdx, UCHAR *EdidBuff) ', we made some modification,using the blue part to instead of read part,

 

BOOL  APP_SplitterMergeEdids(UINT16 SegIdx, UCHAR *EdidBuff)

{

……

#if 0

     VideoMerge = (VID_COMBINE_3D|VID_COMBINE_4K);

     EDID_CombineParams (&EdidParams[1], &EdidParams[0], &CombParams);

    /*====================================

     *

     *===================================*/

    if (EDID_ParmsDiffer (&CurrParams, &CombParams))

    {       /* mbw this will require all packets and enc state

             to be manualy sent from RX to TX  */

        DBG_MSG("New combined EDID created\n\r");

        memcpy (&CurrParams, &CombParams, sizeof(EDID_PARAMS));

        EDID_Construct (CombinedEdid, &CombParams);

        memcpy (EdidBuff, CombinedEdid, 256);

        return (CHANGED_EDID);

    }

    else

    {

        memcpy (EdidBuff, CombinedEdid, 256);

        DBG_MSG("Combined EDID did not change\n\r");

        ADIAPI_XRepRxTriggerReceivedPackets (&Pkts);

        return(SAME_EDID);

    }

#else

if(App_IsEdidCopy()&&(App_IsOutConnectFirst()))

   {

      App_OutConnectFirst(FALSE);

      memcpy(CombinedEdid, EdidBuff, 256);

      return (CHANGED_EDID);

   }

else

{

     memcpy (EdidBuff, CombinedEdid, 256);

     return(SAME_EDID);

}

#endif

}

 

2. the result,

  1. TXB will not be affected when plugout TXA
  2. TXA will not be affected when plugout TXB
  3. EDID won't be updated to RX when plugin TXA, while TXB will be affected by a flash.
  4. TXA won't be affected when plugin TXB, but there's no display on TXB end,which display '-T2: 53:953 #### Muted using: TMDS BLKOUT ASP (RX Video not detected)' in uart information.
