Identify sources
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. For the Networked VGA Grid, sources are remote
from the VGA Grid and are connected to VGA Grid HD Encoders.
This chapter covers the following sections:

Previewing captured stream from sources
Connecting sources
You can connect sources to the Networked VGA Grid at any time, either before or after the system is powered
on. Similarly you can disconnect a source from a port and even connect a different source at any time.
Changing the source connected to a port that is being streamed or recorded can result in the
recording stopping or the stream frame size changing depending on how your channel is
configured.
If the frame size changes, viewers may be disconnected and need to re-connect to the stream.
Connect the input sources to the following input ports on the system:
Table 19 Cable and port connections
Cable Input Port
VGA, HDMI or DVl DVI port
composite or S-video source S-Video port
audio Audio Input port
The web interface automatically discovers all input source ports and displays them in the Stream Setup section
of the encoder's channel on the VGA Grid web admin interface after the encoder is added as a channel to the
VGA Grid. (See Add an encoder to the VGA Grid ).
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. Fine tuning is available through the VGA Grid HD Encoder's web interface.
