| HDCP - High-bandwidth Digital Content Protection |
| |
HDCP
is a content protection specification to protect digital entertainment
content across the DVI/HDMI interface. The HDCP provides a robust,
cost-effective and transparent method for transmitting and receiving
digital entertainment similar to DVI/HDMI-compliant digital displays.
HDCP encrypts the data transmitted between the DVI/HDMI connector on
the graphics adapter and the display. To provide this support, both the
graphics adapter and the display need to have an HDCP transmitter and
receiver respectively. |
