Aspect Ratio
Aspect ratio information can be encoded within a video signal following different
standards: AFD 2016, AFD VI, or WSS. The Kaleido-X software may use this information to
render the video raster in the target video window on the monitor wall.
The aspect ratio of video displayed on the monitor wall can be automatically adjusted. With
multiple video players (monitors) on a monitor wall, in multiple formats/aspect ratios, this
makes it easy to switch from one format to another in the same player. Automatic
adjustment can be accomplished in two ways:
• Video monitor slaved to input: A video monitor can be slaved to the input format such
that the video monitor will change its aspect ratio according to the input signal type
(e.g., SD, HD, DVI).
V-chip monitor The V-chip monitor provides a visual indication of the V-chip rating from the
CC (608) metadata in an SD video signal, or from the CC (608) legacy caption
data, when such data is present within an HD video signal. Requires the
CC/XDS option. See
Hardware and Software Options , on page 463, and
Configuring V-Chip Monitors , on page 302.
Clock A clock is the visual representation of time in a video or display. It can be
based on a reference LTC signal or on the multiviewer system time. Clocks
can be in a digital or analog format. See
Configuring Clocks on page 304.
Note: The KMV-3901/3911 supports digital clocks only.
Widget library A widget library is a collection of predefined layout elements. Monitors from a
library can be used to help construct a layout. Default widget libraries are
available from XEdit’s Tools pane. You can also create your own libraries.
See
Managing Widget Libraries on page 318.
Note: As of version 7.40 of the Kaleido-X software, two new 16:9, and 4:3
composite widget libraries with proportional elements are available. In these
libraries, the primary monitors within each composite have all their
dimensions defined as a percentage, which allows intuitive resizing, whereas,
in the legacy maximum video area libraries, some primary monitors have fixed
height or width, to allow more space for the video window. The new
composite monitors with proportional elements suit most purposes. It is
preferable to always use them, unless you specifically require monitors with
fixed dimensions.
