3025SW Master Control Switching & Channel Branding
Page 138 Revision 1.0
Background Input: When the DVE is triggered this is the 3025SW input that will be used for the DVE A
or DVE B background. If the background input is configured for PGM/PST then the
background will be the input routed to the PST BUS if the move is previewed and
the input routed to the PGM BUS if the move is taken on-air. Other possible
sources are KEY/FILL 1, 2 & 3, DVE 1 & 2, EMG and AUX 1, 2 & 3. NOTE:
Depending on the version of EMC-Setup you have you might need to convert the
3025EMC background source name to the 3025SW BNC input number. See Page
15 for more details on this
Source: This does not
apply to the 3025SW as there is no upstream router connected
to the 3025SW inputs. This setting should always
be UNCHANGED.
If both DVE A and DVE B are on-air at the same time and the background inputs are different then
whichever DVE, A or B, currently has priority the background source for this DVE will be used.
7.2.2.5. Audio Source
This control allows the user to specify the audio background source for the DVE move. This control will
define if additional audio will be mixed with the Program or Preset sources.
Figure 7-4: Audio Tab
Foreground Source: This is fixed to either Program (Take DVE-A) or Preset Input (Preview DVE-A) for
either a DVE-A or DVE-B move. The ratio is set to a percentage of the overall audio. A
value of 0% is will indicate that the audio from PGM/PST will be muted during the DVE
move.
Background Source: This is selectable from None, V/O1, V/O2, V/O3 or 4 for a DVE-A or DVE-B
Move. The ratio is set to a percentage of the overall audio. A value of 0% will indicate
that the audio from the Background Source will be muted during a DVE move. None
specifies that no audio effects will take place during the DVE move, i.e. the PGM/PST
audio will be unchanged as a result of the move taking place.
Audio Transition Rate: This is the transition rate that the audio is mixed during the Primary DVE move.
This is represented in term of fields for interlaced and frames for progressive. This would
normally be less than the transition rate of the DVE moves itself.
