Presenter Mode User Guide
Welcome
This document explains how to use the VBrick 9000 encoder when in Presenter Mode.
Presenter Mode requires the use of a Presenter encoder or activation of a
Feature License on a standard encoder.
Note: When viewing the images in Online help, keep in mind that many of the
configuration options for the encoder are mutually exclusive. This means that,
depending on which options you select, you may see new fields or you may not see
previously existing fields. Although the images may not always show all options, they
are fully explained in the text.
Chapter and Topic Organization
This Online help system provides access to the VBrick 9000 Presenter Mode Encoder
documentation. Topics may be used as reference material or as how-to materials for specific
use cases.
For best results, please take a few moments to familiarize yourself with the way the
information is organized. If you find errors or omissions, click the e-mail icon in the upperright corner of this window or send your feedback to

Presenter Mode Features
Presenter Mode Overview
Presentation features support the ability for you to stream video and Webcasts directly from
an encoder using an intuitive Presenter Mode interface. Presenter Mode is based on layouts
defined by an account admin which are covered in the
VBrick 9000 Encoder v4.3 Admin Guide.
When streaming, you may dynamically switch between layouts and video/network inputs
without interruption to the video stream and without the need to restart the player. Layout
configuration values may also be seamlessly switched as well including the background color
and image, borders, and margins. This provides the ability to create very compelling video
Webcasts. Note: These seamless transitions do not apply to changing encoding values within
VBAdmin.
This guide covers how to use Presenter Mode to run a presentation that has been previously
configured by an admin. As noted, how to configure the layouts and set up used in this guide
is covered in the
Presentation Features topic of the VBrick 9000 Encoder v4.3 Admin Guide.
Presentation Features topic of the
Chapter 1
This user guide covers the following topics:
• How to choose and modify a layout for your presentation
• How to start a presentation
• How to broadcast a presentation
• How to record a presentation
Note: The presentation features discussed in this topic are applicable to the Presenter
encoder (number p/n 9311-1612-100) and any standard encoder that has the Presenter
Encoder Feature License (7100-3000) applied (See: Admin >
Manage Configuration > Presenter Encoder Feature License topic for more details on
how to install this license). As a reminder, not all features may be present on encoders
with the Presenter Encoder Feature License installed.
System Configuration >
Presenter Mode Login
If enabled by an admin, the Manage Presentation button will appear on the Login screen
which will enable you to go directly to Presenter Mode without the need to log in to
VBAdmin first.
VBrick 9000 Encoder Presenter Guide 7
Page 8
If this button has not been enabled, logging in to VBAdmin will be required first to enter
Presenter Mode. You may then click the
navigation menu to access Presenter Mode.
Manage an Event
There are three steps to managing an event in Presenter Mode:
1. Select a layout(s)
2. Configure a layout(s)
3. Control your event/presentation
Manage Presentation button at the top of the left
Select a Layout
Your admin has enabled and configured up to seven layouts with default video or network
sources and layout (color/border/margin/background image) configurations that you may
choose to use for your presentation.

Presenter Mode Features
Select a layout from the Layout Selection area and click the Apply button. You may then set
your own values for the selected layout in the
Layout Configuration area if you want to change
the default values your admin has selected.
Tip: Keep in mind that layouts and their configuration values may be switched when
streaming without interruption to the video or layout and without the need for the
audience to restart their players. This provides the ability to create very compelling
video Webcasts.
Field Description
Choose Layout Select from the layouts your admin has enabled for use in your
presentation. If a layout is selected here, it is also selected in the
Layout Scroll bar below the Layout Preview box. If you do not see a
layout that you need, contact your admin to have it enabled.
• Single area layout with the selected video input filling the entire
video image.
• Two area layout with each area approximately the same size,
displayed side by side.
• Two area layout with one large area and a smaller area in the
upper right. This is ideal for a single computer screen capture
with live video of the presenter.
• Three area layout with one large area on the left and two smaller
areas on the right. This is ideal for a single computer screen
capture with two live videos.
• Four area layout with one large area on the left and three smaller
areas on the right.
• Four area layout with one large area on the left and three smaller
areas below.
• Four area layout with areas arranged in a 2x2 grid.

Field Description
Layout Preview Displays the currently selected layout in visual format. Each layout
has predefined, unchangeable video areas. Other items in the layout
are configurable such as background colors and borders and what
video sources are mapped to what areas. You admin has likely given
the video areas a descriptive name such as “Camera 1", “Laptop”, or
“Document Camera” so that you will understand what video will be
visible in each area of the layout.
Layout Scroll Functions the same as the Choose Layout dropdown and selects a
layout to use and set default values for when in Presenter Mode. If a
layout is selected here, it is also selected in the Choose Layout
dropdown.
Configure a Layout
Once you have selected a layout in the Layout Selection area, you may choose to use the
default values selected for it by your admin, or define your own values in the
Configuration section. You must click the Apply button to save any changes you make.

Presenter Mode Features
Field Description
Borders A border value 0-50 may be selected with the default set at 0. If a
border is applied, it will be applied to all video areas in the selected
layout. Video will be scaled down to fit the border with no video lost
due to border size. It should be noted that borders are used in
Presenter Mode to control spacing between video areas and the
background color appears in the border area. Borders are not used to
frame video areas.
Margins Margins are useful when inserting branding. Margins are different
from borders in that borders are applied to all video source areas
whereas the margins define the layout area itself. Margins are
specified in pixels.
Program Name Modifies the title of the Presentation.
Video Area
Mapping
Each area in the layout you have selected is assigned a video input
channel. Only the channel is mapped, not the specific input type. For
example, channel 1 is mapped, not channel 1 VGA. You may remap
each video/audio area as needed. Note the status of each area is
noted to the side of the area.
In addition to video sources, network sources may also be selected
here. However, unlike video sources, only one network source may be
mapped at a time so if you have a network source selected and you
choose another in a different area, the first network source will be
disabled.
The caveats below should be kept in mind when switching between
sources.
If you use an encrypted network source and switch to another
encrypted network source:
• Seamless switching between the two sources occurs if both have
the same encryption.
• Seamless switching between the two sources does not occur if
different encryption methods exist between them or if one is
encrypted and other is not.
VBrick 9000 Encoder Presenter Guide 11
If you switch between a video source and a network source:
• If the network source requires decryption, the switch between
video and network sources is seamless between the local video
input and the decrypted stream.
• However, if the video source is playing first, the first time the
encrypted network source is selected, the switch is not seamless.
Every switch thereafter, is seamless.
Page 12
Field Description
Audio Mapping Similar to video area mapping with the exception that only one audio
channel source is selectable for each layout.
Further, in order to switch audio channels within a presentation and
not reset the stream, all audio channels must have the same sampling
rate and audio rate settings. The easiest way to assure this, and a best
practice, is to create the desired audio configuration for one channel
and then use the
Clone button to copy the Audio Rate settings to
other audio channels. After cloning, you can then manually configure
the setting for
How Audio is Connected for each channel if you have a
mixture of analog and digital audio sources.
You may still change audio channels with different settings, but this
will cause a reset of the stream and attendees/viewers may need to
reset their players as a result.
Note: Changing audio channels during a presentation is not
supported for streams with encryption.
Revert/Apply
Buttons
Click Apply to apply any changes you have made to the layout. Click
Revert to discard any changes you have made.
Tip: Keep in mind that you may switch seamlessly between layouts, configurations,
and video inputs when presenting. (Some caveats apply, see the table above with
regard to Video Area Mapping) As a result, consider a best practice of making border
values, margin values, pause images, and so forth consistent between layouts so you do
not have any odd jumps or glitches when switching between layouts during a
presentation.
Control a Presentation
The Presenter has three methods to controlling a presentation. They are:
• Event start/stop
• Broadcast an event
• Record an event
After selecting and configuring your layout, click
stream will then be available on your network with a graphic displaying the pause message
“The host is not currently broadcasting.”
The image displayed during pauses may be changed by your admin in the
dropdown field by navigating to
Start Program to begin streaming. The
Pause Image
Encoder Configuration > Manage Layout Images.
The status bar will change color from red to orange to indicate that you are now streaming
but viewers cannot see your content or hear any audio.
