About the DCS-200
^=tçêÇ=^Äçìí=ea`m
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 a DCS-200 is used, when an HDCP compliant device is connected
to the DCS-200, 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.
Please note the following important points:
When an HDCP compliant device is connected to the DCS-200 and that specific
input is selected, the Status Menu indicates if HDCP is enabled.
If the “session” determines that the target display device is non-HDCP compliant
(e.g., if the user is attempting to make an illegal copy on an external recorder), an
error message appears on the DCS-200’s Status Menu, indicating that video
cannot be shown.
HDCP compliant repeaters cannot be connected to the output of the DCS-200, as
the DCS-200 must be the last device in the HDCP "chain" — prior to the HDCP
compliant display. If an HDCP repeater is connected, the message “HDCP
Violation” appears on the Status Menu. In Chapter 4, refer to the “Status Menu
section on page 44 for additional details.
