Can GMSL1 backward compatible devices support HDCP?
Yes, GMSL2 devices supporting HDCP and GMSL1 backward compatibility can support HDCP. However, GMSL2 style "auto-HDCP" or "HDCP" is not support in GMSL1 mode. In the case of GMSL1 mode, all HDCP authentication and integrity checking must be handled by an external host device.
