Overlay
The Overlay page allows up to 64 characters of text to be displayed over the streamed video
or test pattern. The text can be displayed continuously only when no signal is detected at the
input or disabled. You can also upload a graphic file to use as logo, overlaying the displayed
channel content or test pattern. The graphic file must be a .bmp format and is always
displayed in white with a transparent background, in the upper left corner.
Figure 21 Overlay
Text Display
You can configure up to 64 characters of text to be displayed over any displayed content either
continuously or when no signal is detected at the input. This allows you to specify different on-
screen text for each condition. In the default setting all overlay content is disabled and the text
entry fields are blank. The characters are 12x24 pixels and can be displayed double height
and/or double width if required. All text is displayed in a single line with no wrap-around. The
text is not scaled to suit the display resolution therefore higher resolution output encoding can
display longer text strings. The starting position of the text can be controlled on the display
using the start column/start row entry.
Note:
To ensure text can be viewed when
On when No Input
, or
On and alternate when No
Input
is configured, you should also configure a solid colour test pattern for the No Input
condition as described in Test Pattern Mode on page 42. (The AvediaPlayer receivers
automatically display a
“Channel Unavailable” message.)
