Dear expert,

There are some repeaters in market will block HDCP function. It couldn’t be used in factory.

May I learn from you if TPD158 can bypass HDCP1.4/2.2 or not?

Ben

  • HDCP handshakes are done through DDC, and we recommend DDC snoop mode, so DP158 is just monitoring for changes in TMDS_CLOCK_RATIO_STATUS. 

    DP158 just retransmit the HDMI signals, it doesn't deal with encrypted video. As long as both the HDMI source and sink supports HDCP, then HDCP will work.

    Thanks

    David
