HDCP

Last Updated: Dec 01, 2015 04:15PM EST
High-bandwidth Digital Content Protection (HDCP) is a "feature" that is built-in to consumer HDMI interfaces that prevents content from being displayed unless both ends of the HDMI connection are licensed.

HDCP was insisted on by content owners (Hollywood, broadcasters, etc.) to help prevent consumers from making digital copies of DVD's, BluRay, or TV programs.  Of course, as is always the case, work-arounds quickly emraged and are in widespread use but nevertheless HDCP is mandatory on all consumer devices that deliver commercial content.

You should think of HDCP as being supported on virtually all TV HDMI inputs,   

Similarly, HDCP is supported on virtually all Cable-TV boxes, DVD and BluRay players,and on streaming boxes like Roku, Amazon, and similar outputs.

HDCP is generally not supported and not needed on consumer camera outputs.  A camera does not send a signal to a TV display saying "this signal requires HDCP", and TV's will display such a signal.

Encoders, (Spirit, Streamsie, etc.) and capture devices (Captiva, etc.) do not support HDCP input.  Therefore, you cannot connect a consumer Cable-TV box to an encoder without making provisions to deal with HDCP.
