Operation
HDCP MODE: It sets the working mode of HDCP function. There are PATTERN and
PROGRAM two modes for switch.
It automatically executes the HDCP setting. If the HDCP is set up
successfully, the display device will show the pattern directly. If failed,
error messages will show on the display device. The HDCP LINK
process checks if Ri = Ri’ every 2 seconds when the setup is OK. The
LCD panel stops HDCP LINK and beeps when an error is found during
check. The display device may show a noise screen.
This function is mainly to work with Program Run for doing factory
tests. It can set the HDMI Timing or DP Timing respectively to have the
HDCP LINK process or not under the HDCP Enable state. For this
selection, the HDCP ENABLE in HDMI or DP Timing Format should be
set by VPGMASTER or the VPG (the default is NO which means there
is no HDCP LINK process), and save it to a new user timing then it will
have the HDCP LINK process function.
■ Following is the operating example of PATTERN Mode
(1) Select PATTERN mode.
(2) Use a device that supports HDCP and select a mapped timing (ex: HDMI Timing #601)
for output. An HDCP PATTERN Mode verification screen will appear on the screen.
The VPG runs HDCP verification program automatically, and an error message will appear
on the display if the verification fails. When the verification is OK, a selected pattern will
show on the screen and a window will appear on the left corner. The HDCP LINK checks if
Ri is equal to Ri’ every 2 seconds. For the DisplayPort interface, since Ri and Ri’ are
checked at Sink site, their values remain the same during display except the checked
results are changed.
