9 HDCP notes
HDCP stands for High-Bandwidth Digital Content Protection, an industry-wide copy
protection scheme that is used to prevent the potential interception of digital data between
the source (e.g., a Blu-Ray player) and the target display (e.g., an HDCP compliant display
or monitor). The HDCP format was designed by Intel®, and it uses an “authentication and
key exchange” procedure to accomplish the required protection. For proper implementation,
products that are compatible with the HDCP format require a secure connection to a
compliant display, such as a projector or monitor.
In applications in which the DVI router is used, when an HDCP compliant device is
connected to the router, an HDCP “session” is created. In this session (which is transparent
to the user), “keys” are exchanged between the source device (e.g., a Blu-Ray player) and
the HDCP compliant display.
The source device queries the display to ensure that the equipment is HDCP compliant
before video is shown. Non-HDCP equipment such as PCs will work with any DVI compliant
display, but HDCP compliant equipment only shows “protected” content on HDCP compliant
displays.
