What is HDCP?

HDCP stands for High-Bandwidth Digital Content Protection,

a speciﬁ cation developed by Intel

for protecting digital

entertainment content that uses the DVI interface. HDCP is a

copy protection scheme to eliminate the possibility of

intercepting digital data midstream between the video source,

or transmitter - such as a computer, DVD player or set-top box -

and the digital display, or receiver - such as a monitor, television

or projector. In other words, HDCP speciﬁ cation is designed to

protect the integrity of content as it is being transmitted.

English

Products compatible with the HDCP scheme such as DVD

players, satellite and cable HDTV set-top-boxes, as well as few

entertainment PCs requires a secure connection to a compliant

display. Due to the increase in manufacturers employing HDCP

in their equipment, it is highly recommended that the HDTV or

LCD monitor you purchase is compatible.
