What is a source?
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, DVI or HDMI video signal and audio signal output.
The Admin panel automatically discovers all sources connected to your HD Encoders and displays them in the
Stream Setup section of the encoder's channel on the VGA Grid Admin panel after the encoder is added as a
channel to the VGA Grid. (See
).
Video sources are also displayed on the Epiphan Live control interface. See
for more information.
When a source is connected to an encoder, 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, however fine tuning is available through the VGA Grid HD Encoder's Admin
panel.
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)
If there is no signal coming through an HD Encoder, then the default "No Signal" image will display in any
channel where the HD Encoder source is used. You can use Networked VGA Grid.'s default "No Signal" image
for your sources, or you can create your own custom "No Signal" image for your local custom channels to
enhance branding and add professionalism to your display. See
Add a No Signal image to a source
