The matrix allows transmitting HDCP encrypted and unencrypted signals.The devices will be still HDCP
compliant as they will never output an encrypted signal to a non-HDCP compliant display device. If an

10.2.1. Protected and Unprotected Content
Many video sources send HDCP protected signal if they detect that the sink is HDCP capable – even if
thecontentisnotcopyrighted.ThiscancausetroubleifanHDCPcapabledeviceisconnectedbetween
