Conguring DPF Input Files
During start-up, the system automatically detects any associated third-party capture
device and creates a DPF le for each device in the C:\ProgramData\Daktronics\
Vnet4\Content\Devices folder. These input les can be triggered from the system’s
control interface such as Display Studio. A DPF le provides the
player with information for the following actions:
• Select capture device connected to the video stream.
• Specify video ltering.
• Enable/disable audio.
Refer to Figure 55 and the table below.
Note: To customize a DPF le, use the automatically generated DPF le as a template,
make any changes using Windows
®
Notepad, then save the le with a new
name. Since the DPF le is re-generated during each startup, if the customized
le is not re-named, it will be overwritten on the next startup.
