PATTERN SUMMARY

In the example above, the HDCP authentication process is successful. Note that the sink (Rx) was not identified as a repeater. For a display, this is normal.

A repeater is defined as an active device which has one or more HDMI inputs and one or more HDMI outputs that work with HDCP. A repeater is an active device because it decrypts HDCP content on the input (Rx) and re-encrypts on the output (Tx).

Motion
