VGA Grid User Guide
This chapter outlines how a suitable design of a broadcast can be architected based
on these types of questions and their resulting answers and how the VGA Grid can
be used in this design.
The VGA Grid supports streaming of various standards and formats. The choice of
video format will depend on the broadcast content and performance requirements.
For example, Motion JPEG does not support audio from an external source. It also
depends on how the intended viewers are planning to receive and play the
broadcast. Keep in mind that browser viewer capabilities and compatibilities are
subject to change.
With the VGA Grid, the video stream format is selected by an administrator. All
users must view the broadcast in this format. In the case where an experienced user
wants to view the same broadcast but requires different stream formats, it is
possible to configure channels for streaming different video formats of the same
broadcast to meet this requirement.

video data is processed.
