2.2. This is an issue if the output of the Radiance Pro is connected to a HDCP 1.X TV, or projector, since the
Radiance Pro will then be required to disable video, because the TV, or projector, is not HDCP 2.2.
Generally, if a HDCP 2.2 capable set top box or UHD Bluray player sees a HDCP 1.X device on its output, it
will downgrade the video resolution and output as HDCP 1.X. This command allows the user to tell the
Radiance Pro to report only HDCP 1.X capability back to the source so at least a downgraded video format
will be output from the set top box or UHD Bluray player for 4k sources, and the Radiance Pro can output
the HDCP 1.X video to the HDCP 1.X TV, or projector. The command is:

HDMI Video Type
By default, the HDMI input format is detected automatically using the
HDMI Info Frame
. For DVI sources,
the Auto mode selects RGB format. For sources that do not report their format correctly, the input format
can be selected manually.
Set to “Auto” for YCbCr 420.

Input Level
This command specifies if RGB HDMI inputs use video levels or PC levels. The input video level should be
set to match the expected range of the video source. A mismatch can cause the image to be too dark or too
bright. The command is only applicable for the RGB input format. The command is:

Auto Aspect Selection
For HDMI sources (not DVI), aspect information may be sent from the source. Enabling HDMI Auto-Aspect
allows the source to select the input aspect ratio using the HDMI Info Frame aspect ratio information. The
Radiance Pro can also automatically detect the input aspect ratio by analyzing the image to see if it fills the
height of the source raster. Options for Auto Aspect are Off (default), HDMI (only), Image (only) or HDMI
plus Image based auto aspect.
Note:
This feature is intended to be used to detect changes from OSD to movie/program, and not to detect
changes in aspect ration within a program. There is a hysteresis time of several seconds before a change
takes effect. This is not an issue at the beginning of a program, but it is not fast enough to use when the
aspect ratio of the source changes within the program.
Since the image-based auto aspect analyzes the video, it is possible in rare cases that one aspect ratio
might be mistaken for another. This typically only occurs with very poor-quality video originally shot, and or
edited, in the analog domain.
If the user manually selects an aspect-ratio, by default, that aspect-ratio will be used until the next aspect
ratio change is detected by the Radiance Pro. If enabled, the Sticky Aspect Override feature will disable the
image-based aspect-ratio detection and the selected aspect will be used until the input is reselected, the
Input
button is pressed, or a memory (e.g.
MEMA
) button is pressed.
Some users prefer that, for example, 16:9 sources use the NLS function to always stretch the image to fill
an anamorphic screen. If the
NLS when applicable
feature is enabled, when the Radiance Pro detects 4:3,
16:9, or 1.85 as the source aspect, the NLS features is automatically applied if appropriate.
The user can also select whether the automatic aspect ratio detection applies Letterbox Zoom to letterboxed
sources, or not. See the Letterbox Zoom section for more information on letterbox zoom.

Input Aspect Selection Mode
By default, the input aspect ratio can be unique for each input resolution. When a control system is used to
control the input aspect ratio it may be desirable to have a common aspect ratio for a given configuration
memory and allow the control system to select it without regard to the input resolution. This command
controls whether the input aspect is common for all input resolutions for a given configuration memory, or if
each input resolution has a unique aspect ratio. The command is:
