What is a source?
A source can be an image, video, or audio from a camera, a computer screen or any device that provides a
VGA, S-Video, SDI, DVI or HDMI video signal and audio signal output.
Video sources
The web interface automatically discovers all video source ports and displays them in the
Sources
section of
the web admin interface.
Each video input on the back of the system is a frame grabber. Input sources are identified by their frame
grabber serial number. Each frame grabber has one DVI port, one SDI port, one S-Video port, and one audio
port. DVI ports are listed with the suffix .vga, SDI ports with the suffix .sdi, S-Video inputs are listed with the
suffix .video, and audio inputs are identified by the word audio. Video sources include a preview of the images
they are capturing. It is a good practice to view the images from each source to confirm what is captured. See
below.
When a source is connected, the system automatically detects and adjusts the image capture settings at start
up and continues to adjust every 60 seconds during operation (interval is configurable). The system’s goal is to
produce the best quality captured image given the source equipment used. Generally no further
configuration is needed.
VGA Grid HD Encoders can also be used as sources for your Networked VGA Grid Concentrator.
To accomplish this, you must first add your HD Encoder(s) to a channel and then add the channel
as a source. See
Add an HD Encoder as a source (custom channel)
for more information.
If there is no source connected to a specific port , then the default "No Signal" image will display in any channel
where the source is used. You can use Standalone VGA Grid.'s default "No Signal" image for your sources, or
you can create your own custom "No Signal" image for your channels to enhance branding and add
professionalism to your display. See
