What is DVI with HDCP?

[Aspdu]

Is there a difference between DVI-D and DVI w/HDCP when it comes to their structures? Or it's just the same? Sorry about this, I just don't have any idea about this thing.

DVI-D is a type of cable/port. It carries a digital video signal (hence the D).
HDCP is a form of copy protection that keeps you from easily copying whatever you can play on your monitor (streaming video or similar). Certain protected content won't play if you don't use both a HDCP supported output and screen.
Most DVI outputs support HDCP. Most monitors with DVI inputs support HDCP.
