Configuring .DPF Input Files
During start-up, the system automatically detects any associated third-party capture
device and creates a .DPF file for each device in the
C:\ProgramData\Daktronics\
Vnet4\Content\Devices
folder. These input files can be triggered from the system’s
control interface such as Display Studio. A .DPF file provides
the DMP-8000 with information for the following actions:
• Select capture device connected to the video feed.
•
Specify video filtering.
• Enable/disable audio.
Refer to
and the table below.
Note:
To customize a .DPF file, use the automatically generated .DPF file as a
template, make any changes using Windows
®
Notepad, then save the file
with a new name. Since the .DPF file is re-generated during each startup, if the
customized file is not re-named, it will be overwritten on the next startup.
