The top line of the display will show the current output resolution selected. Some
units will have a limited number of output resolutions depending on their function
(e.g. Down Converters are more limited than Video Scalers).
HDCP is handled only on certain units with DVI outputs, so this menu may not
appear on your own unit. HDCP is a ‘High-bandwidth Digital Content Protection’
system, which can ensure that a high definition video signal cannot be received by
units not equipped with a HDCP receiver.
This menu lets you see the current status of the output and whether HDCP is
supported or active, and also lets you turn off the output’s HDCP encryption system.
Note, however, that turning HDCP off at the output will also prevent HDCP-encrypted
signals from being received by the unit – see the table below.
By default, HDCP on the output is turned On - so that if your attached DVI display is
HDCP-compliant, then your output will be encrypted (regardless of whether the input
to the scaler is encrypted). Note that you don’t have to attach a display to the output
of the scaler – another unit can be connected instead, in which case that unit is
known as a ‘repeater’.
Please also see the HDCP menu item in ‘Adjust sources’, as this controls availability
of HDCP at the DVI input. The status message given in brackets has the following
meaning:
Status
message Description Effect
Unavailable The device attached is not
capable of supporting HDCP. As the DVI output cannot be HDCP encrypted, then a
HDCP-encrypted source cannot be selected for
scaling.
Supported The device attached is
capable of HDCP, but the
output is not currently
encrypted. As the DVI output is not HDCP encrypted, then a
HDCP-encrypted source cannot be selected for
scaling.
Active The device attached is
capable of HDCP, and the
output from the unit is
encrypted. As the DVI output is HDCP encrypted, then a HDCP-
encrypted source can be selected for scaling. Note
that no other output connector (SDI, CV, YC, YUV or
RGBHV) will function – since they are not encrypted.
Rep. supprt The repeater unit (e.g. scaler)
attached is capable of HDCP,
but the output is not currently
encrypted. As the DVI output is not HDCP encrypted, then a
HDCP-encrypted source cannot be selected for
scaling.
Rep. active The repeater unit (e.g. scaler)
attached is capable of HDCP,
and the output from the unit is
encrypted. As the DVI output is HDCP encrypted, then a HDCP-
encrypted source can be selected for scaling. Note
that no other output connector (SDI, CV, YC, YUV or
RGBHV) will function – since they are not encrypted.
