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.
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.
