The ImagePRO-II supports
High-Bandwidth Digital Content Protection
(HDCP), an
industry-wide content protection system designed to prevent illegal copying of digital audio
and video content across interfaces such as DisplayPort (DP), High-Definition Multimedia
Interface (HDMI), and Digital Visual Interface (DVI). HDCP prevents the display of
encrypted content on devices that do not support content protection.
The HDCP format was designed by Intel
®
Corporation, 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.
When an HDCP-compliant display is connected to the ImagePRO-II, 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
displayed. Non-HDCP equipment such as a PC will work with any DVI-compliant display,
but HDCP-compliant equipment shows protected content only on HDCP-compliant
displays.
With the HDCP option enabled, the ImagePRO-II accepts encrypted content from an
external source, decrypts the signal for internal processing such as scaling or color
balance, then re-encrypts the output video for display. During this process, all
ImagePRO-II output connectors that are not HDCP-compliant are turned off.
This feature is available on the ImagePRO-II’s
DVI
,
HDMI
, and
DP
input and output
connections.
