Aspect Ratios - Crestron C2N-DVP4DI Reference Manual

Crestron C2N-DVP4DI
Reference Guide – DOC. 6177A
The C2N-DVP4DI moves the image ten pixels down and ten pixels to the right.
Then the C2N-DVP4DI scales the image to fit on the reminder of the screen. In this
case, set the horizontal and vertical offset to zero.
Analog Touch Join - Width adjusts the horizontal size of the video. The C2N-
DVP4DI will not display the video if you enter an analog value of zero. The
maximum value assigned to Width is the horizontal resolution of the C2N-DVP4DI
output, not the input resolution.
Analog Initialize Value
When you assign an analog value to height and width, you must also assign an
analog initialize value to that analog join number in SIMPL Windows. Without an
analog initialize value, video will not be present when you do a page flip or sub
page.
An analog value of zero has an image size of zero pixels for height and width.
If you also want the video to appear in a particular position on the screen, you must
set the top and left position values in an analog initialize. If no analog value is
assigned, the C2N-DVP4DI defaults to the upper left corner of the screen, regardless
of where you have drawn the window location in VT Pro-e.
NOTE: When drawing a two-dimensional slider to control the size and position of
the video, the first analog number is for the horizontal axis and the second number is
for the vertical axis.

Aspect Ratios

Maintain the proper aspect ratio when setting the initialize values. Refer to page 97
for additional information on aspect ratios.
•
To maintain a 4 X 3 aspect ratio, multiply the height by 1.33.
•
To maintain a 16 X 9 aspect ratio, multiply the height by 1.78
Example: Assuming the height is 100:
Aspect Ratio Height
4 X 3 100
16 X 9 100
Assigning a Source, Transition and Duration
There are two ways to assign a source, transition and duration (timing) default
analog value:
•
Defaults – allows the user to assign the video source, transition or timing to
be used when a page flip, digital logic join or sub page is activated. The
selection can be overwritten with analog joins (refer to "Changing Size and
Position using Analog Joins" on page 37).
•
Select Properties – allows the user to select the size and position of a video
window, digital feedback joins (used for diagnostics), and allows the user to
enter a project description in the Description field.
For additional software information, consult the VT Pro-e help file.
