In Frame-lock mode, the output resolution is independent of the lock source, but the frame-rate must
match that of the source (e.g. 1280x1024 60Hz can be frame-locked to 640x480 60Hz). Frame-lock is very
useful for synchronizing a HD-SDI output (e.g. 1080i 59.94Hz) to a composite video source (e.g. NTSC), or
for scaling one resolution to another while avoiding any potential frame-rate conversion artifacts.
'H/V shift' can be used to align the output to the input more accurately, but this may cause instability until
the lock is re-acquired ('Frm.lock' will flash).
Before turning the Lock feature on, you first must select a valid Lock source. Some units may not have all
Lock sources available, depending on hardware limitations – see Specifications for details of limitations on
your unit.
If the Lock source you choose is not valid, then Genlock or Lock & Mix will be temporarily disabled, until
the Lock source becomes valid again. When disabled, the resolution previously specified in ‘Output res’
becomes the output resolution.
Your unit can handle a very wide array of inputs and convert them all to a single output signal with
defined characteristics. This output resolution will remain in place until changed or it may be overridden
by the lock mode and source.
The top line of the display will show the current output resolution selected. The default output resolution
is 720p60.
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 status of the output and whether HDCP is supported or active, and 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’.
It is important to note that if your source is HDCP encrypted (for example, from a Blu-ray player) then you
cannot output any un-encrypted signals that use this source (such as SDI, analog YPbPr, etc.). Only HDCP-
encrypted DVI or HDMI can be output. If your source is encrypted, ensure that this HDCP setting is On
and that your display is HDCP compatible.
Please also see the HDCP menu item in ‘Adjust sources’, as this controls availability of HDCP at the DVI
input.
