configurations that exceed the normal processing capacity of the unit causing it to not
perform optimally. Corrective action usually involves reducing a video rate or disabling a
stream or transmitter. In general, video quality improves when video rate is increased toward
the maximum of 20 Mbps. In short, video quality is subjective and relates to other
components such as the response of the human eye, the quality of the original content and
signal, and the quality of the decoder and monitor.
As a general rule, use the lowest video rate that best suits the application. When configuring
VBrick devices, pay close attention to the total bit rate of all streams exiting the unit. The
sum of all streaming traffic should be closely monitored and kept to a minimum whenever
possible. Once you have selected and applied a configuration to the unit, you can check the
status of the processor and device load using VBAdmin or CLI. The CPU utilization and
overloaded status variables are an excellent indication on the unit's overall health. If the CPU
utilization is high or an overloaded condition is occurring, you can simply reduce bit rates;
reduce the number of streams, transmitters, or served clients; and re-run the test. As a part of
regular maintenance, you should periodically check the
(on the Monitor > Monitor the System page) to ensure the unit remains within normal

operating limits.

Step-by-Step Initial Set Up Overview

This section gives a quick overview of the steps you would typically need to perform to
configure a VBrick 9000 Encoder. As shown in the figure below, the encoder supports up to
four video input streams (two in each slot) and four audio input streams (two in each slot). It
also support a fixed number (shown in parentheses) of programs, streams, transmitters, and
servers.
Keep in mind that the encoder you actually purchase comes in a variety of models with
different connectors and slot configurations.
To quickly configure an encoder:

1. Set up the encoder and connect a video source. See: Getting Started Guide.
2. Configure the Video and Audio sources.
3. Configure the Programs associated with each stream.
4. Configure the Streams for the programs.
5. Configure the Transmitters for the streams.
6. Configure the Servers for the streams.
7. Configure the Archivers for the streams.
8. If you complete the above steps successfully, the encoder will be configured.
