Whenever there is a mismatch in the incoming and outgoing aspect ratio, the Aspect-Ratio
control options allow you to define how the incoming video signal is altered to fit into the
image space of the selected output resolution. To change selection, click radio button
corresponding to desired operating mode from the following options:
-
Minimal – Minimal is the default selection. Minimal attempts to process incoming images
without scaling and will only scale images that do not fit into the selected output resolution.
Incoming images are centered over a black background with the image space of the selected
output resolution. Input video with resolutions lower than the selected output resolution
will display with black bars on all four sides of the output image; as the input resolution
increases, the size of the black bars decrease accordingly in the output image. With input
resolutions higher than the output format, the output image resolution is down-scaled to fit
the transport format. In all cases, the original aspect ratio of input video is maintained in
the output image.
-
Scale-to-Fit – Scale-to-fit will up-scale or down-scale images to just fit within the selected
output image resolution while maintaining the aspect ratio of the original image. Black bars
may appear on the output image in pillarbox fashion on the sides or letterbox fashion at the
top and bottom of the image – but not both
-
Full-Screen – Full-screen scales the input image both horizontally and vertically to
completely fill the output image space – this setting can alter aspect ratio of original input
signal.

Display Output Type
Output Port selection determines type of the video output signal from the RX module. To
change selection, click radio button corresponding to desired output port from the following
options:
-
Auto – Automatically selects DVI or analog output type same as type of input signal to the
Vidblox TX module based on data contained in the auxiliary data packet embedded into the
SDI signal received from transmitter. If the input signal to the RX module is a source other
than a Vidblox TX module, the output type is selected to be the same as the incoming video
signal.
-
DVI – Active output signal is present only on DVI-D outputs of DVI-I connector.
-
Analog – Active output signal is present only on analog outputs of DVI-I connector.
