What is HDCP?

HDCP stands for High-Bandwidth Digital Content Protection,

a speci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 specication is designed to

protect the integrity of content as it is being transmitted.

English

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.

2.8 Jumpers Setup

The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose
pin1 and pin2 are “Short” when jumper cap
is placed on these 2 pins.

Jumper Setting Description

Clear CMOS Jumper

(CLRCMOS1)
(see p.2, No. 26)

Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the
system parameters to default setup, please turn off the computer and unplug

the power cord from the power supply. After waiting for 15 seconds, use a
jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However,
please do not clear the CMOS right after you update the BIOS. If you need

to clear the CMOS when you just nish updating the BIOS, you must boot
up the system rst, and then shut it down before you do the clear-CMOS ac­tion. Please be noted that the password, date, time, user default prole, 1394

GUID and MAC address will be cleared only if the CMOS battery is removed.
