Figure 26. Test Patterns
•
Color Bars
— Standard full screen color bars overlaid on top of the current layout.
•
Time Stamp — Displays white text with the unit date and time (for example: Fri
Apr 18 HH:MM:SS ) in the top left corner of the display window. It updates every
second.
•
Pulse — Select Pulse to output an audio pulse of 400 Hz at -10 dBu for audio
output testing.
•
Crop — Outlines the active picture area.
•
Aspect Ratio — Three patterns with screen outlines in 1.33:1, 1.78:1, and 1.85:1
for centering and size adjustment.
•
Universal OSD — This pattern consists of white text overlaid atop the source
video content. By default, it appears in the upper left corner of the screen. The
location of the universal OSD is dependant on the position selected for the
metadata OSD. The text includes brief custom text followed by three selectable
elements separated by commas. The options for those elements are listed in
Setting up the universal OSD test pattern
.
The universal OSD pattern can be displayed together with the main AV content
because it overlays the video rather than replacing it. The universal OSD pattern
can be used at any time, not just during setup. It can also serve as an on screen
label for presentations, in addition to metadata labels (see
Encoder Settings and
Metadata on page 42 for more information on metadata within screen layouts).
The selected test pattern is immediately output to the display and reflected in the
preview in the
AV Controls panel. The test pattern displays until another pattern,
or Off is selected from the Test Patterns drop-down list, or until unit power is
recycled.
NOTE: When a test pattern is selected, the test pattern is streamed to the display,
stream, and recording, overlaid atop the source AV material. If Off is selected
from the Test Patterns drop-down list, the test pattern is turned off.
