What is HDCP?

HDCP stands for High-Bandwidth Digital Content Protection, a

®

speci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 specication is designed to

protect the integrity of content as it is being transmitted.

Products compatible with the HDCP scheme such as DVD

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

English

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.
