2. Select the category button to which the preferred still image or the
audio mix over branding source has been assigned.
3. Enter the source number that designates the preferred source.
Note For example, above in Figure 6 , the SMPTE Bars mnemonic is assigned to
source number 11 in the LOGO category.
4. Press any PST button, which is illuminated green on either the Keyer or
the Audio panel, to assign the selected source to that button. (The type
of panel depends on the source type that you wish to assign)
The text ‘Loading” will then appear in the PST button.
The specified mnemonic for the selected source will then appear in the
PGM LCD button.
Note Assigning a branding element source to a video keyer or audio over mixer
causes the content associated with that source, as defined in the Content Def-
inition table in the Maestro configuration, to be loaded into the on-board
frame buffer (still images) or clip cache (audio files).
When a still image or audio voice over branding source is assigned to a
video keyer or audio over mixer, the following takes place:
• The source is copied from the branding hard drive.
• The still images are converted to a video image.
• The source is loaded into either a Maestro video frame buffer (still
images) or an audio clip cache (audio files).
Note When the mnemonic for the source appears on the LCD button, the process
above is complete. The time it takes to complete this process varies based on
source file size; it can be from near instantaneous to several seconds. The
text “Loading” will be displayed while the file is loading. If the “Loading” text
does not disappear, the source has failed to load.
Source Assignment Considerations
Because of the nature of branding elements, the content that is associated
with a particular branding element may change from time to time. For this
reason, it is important to verify the content of the element on the PST
monitor before it is aired.
Note Branding elements are loaded when they are assigned to a video keyer or
audio over mixer. If the branding element is still loaded in the on-board still
image store and its content has changed on disk, there may be a mismatch
between the expected and observed on-screen content.
