2 Overview
2.1 Introduction
Epiphan’s VGADVI Recorder Pro™ and VGADVI Broadcaster Pro™ are professional
multi-source audio-video hardware products that combine both Ethernet-based
streaming and recording functionalities. These products are ideal for streaming and
recording multiple visual sources for live events, webinars, presentations, lectures,
and training events. They capture video signals at resolutions up to 2048×2048 and
stream the input channels with a capture rate up to 80 FPS providing a simple and
cost-effective web presentation solution for trainers, tech support, conferences,
enterprises, events, sales staff, distance education providers, and more.
The Pro series of the Epiphan’s broadcasters and recorders features a wide range of
functionalities. It allows you to set up streaming and recording in the most suitable
manner making your video and audio content available for any audience no matter
how large it is. These versatile solutions have a variety options enabling you to
create and configure any number of streaming channels meeting different viewers’
needs whichever they are. Further in this document both products are referenced as
System.
You can configure the System to synchronize, stream and record video sources as
multi video channel streams. It is possible to configure multiple Picture-in-Picture or
Picture-with-Picture layouts, and specify the size and position of all input sources as
you want them to appear in the single output channel.
The System captures data from the following input sources (up to four, depending
on the model):
a DVI/VGA/HDMI source,
an S-Video or composite source, and
an analog audio source.
Having created a required number of channels and configured encoding parameters
for each channel, you can stream video to one or several output URLs. Each channel
being streamed is automatically assigned a unique URL. The channel streams are
viewed in standard browsers and media players. The channel can be recorded to
.AVI or .MOV formatted files.
The key difference between the System models is their form-factors. The form
factor type defines the number of input ports that the model can have and the
possibility to select one of the available storage options for the model.

Confirming that the input signals are being received by the System in Compact formfactor (HD Compact and DL Compact models) can be done once the System has been
powered on and the input sources have been started.
Check that the System’s red LED is blinking. A blinking LED indicates that the System
is capturing images. If the red LED does not start flashing, check the input sources
to ensure that they are transmitting a signal. Additionally, check that all cables from
the input sources to the System are connected correctly.
4.2.1 Checking the Signal from the Input Sources
The System does not come equipped with a mechanism to confirm the quality of
the video input being received via its input video sources prior to recording or
broadcasting signals. However, you can check the presence of the DVI/VGA/HDMI
or S-Video/composite signal on the DVI Source Setup or S-Video Source Setup page
accordingly. These pages are described in the DVI Source Setup and S-Video Source
Setup sections.

Alternatively, the Network Discovery Utility can be used to retrieve the System’s IP
address and access to the Web admin Interface will be done using a browser.
4.4.2 Logging into the Web Admin Interface Using a Web Browser and the
IP Address of the System
The web browser can be running on Windows, Mac OS X, Linux or any other
operating system.
1. Start a web browser on any workstation connected to the same network as
the System.
2. Browse to the System.
http://<IP address of the System>/admin
The IP address of the System can be obtained using any of the following
methods:
a. The Epiphan Network Utility
b. The EpiphanTouch app
c. From the network administrator
d. Using the Factory Default static IP address. Only if the steps in
section, Connecting Directly to the System, are followed
3. Log in as the System’s administrator user
User Name: admin
Password: configured password <ENTER>, there is no factory default
password so unless a password has been configured, just press <ENTER>
The Web Admin Interface opens.
4.5 Users Logging
The System comes with two pre-configured users which are used to log in the
control interface.
The first is the administrator user. Its user name is admin.
The second is the viewer user. Its user name is viewer. Each user can be assigned a
password but their user names cannot be altered. It is not possible to create new log
in users.
4.5.1 The Administrator User
The administrator user is used to log into the System and perform any of the
following functions:
1. Perform configuration changes to the System.
Getting Started

2. Manage the current broadcast. This can include the starting or stopping of the
recording of the broadcast.
3. Manage previously recorded broadcasts including the archiving of recordings.
4. System monitoring. This would involve retrieving any system statuses and
retrieving the solid state memory status.
5. Upgrading the System Firmware from Epiphan Support. New firmware is
released to fix known problems or to add new features.
As a default factory setting, the administrator user does not come with a password
but it is recommended that a password is configured as early as possible for security
reasons.
4.5.2 The Viewer User
The viewer password is used to log in to view broadcasts and does not have any
administrative ability.
As a default, the viewer user does not come with a factory configured password.
Configuring a viewer password is optional.
4.6 Web Admin Interface

6 Video Formats and Standards
The System supports recording and 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 stream. Keep in mind that browser viewer capabilities and compatibilities
are subject to change.
The System can stream video using the following formats: Flash (H.264), ASF
(MPEG4 or H.264 codecs), Motion JPEG or RTSP (MPEG4 or H.264 codecs). A quick
definition of these video streaming methods and the type of application that a
viewer would use to watch that particular video stream is now provided.
The Adobe Flash Video file type is proprietary but is supported on most web
browsers and on many media players including the VLC Media Player. This file type
supports the H.264 standard. This video supports analog audio from an external
source.
The Advanced System Format (ASF) file type also know as Advanced Streaming
format, can be viewed with the Windows Media Player or the VLC Media Player.
Additional codecs may need to be installed to view ASF files. This file type supports
H.264 and MPEG4 standards. This video supports analog audio from an external
source.
The Motion JPEG file type records each frame in the video in JPEG format and can
be viewed using most web browsers. This video format does not support analog
audio from an external source.
The RTSP type supports many media players including QuickTime and MPlayer. This
file type supports H.264 and MPEG4 standards. This video supports analog audio
from an external source.
Media Player, Browser, Viewer capabilities and
compatibilities are subject to change.
