DVI Broadcaster DL User Guide
2Overview
2.1 Introduction
The Epiphan DVI Broadcaster DL is an external device designed for streaming and/or
recording the video content from one connected source and optionally the audio
from one connected audio source. Its DVI In port can support any of the following
video sources:
- DVI (either single link or dual link)
- HDMI
- Other compatible sources with appropriate adapters and/or converters (e.g.
Thunderbolt, DisplayPort, and mini DisplayPort)
This compact external device captures DVI or HDMI video signals in resolutions up to
2048x2048 or2560x1600 for widescreen applications. The DVI Broadcaster DL then
streams the captured content in compatible formats allowing the broadcast to be
viewed with standard internet browsers and media players.
The DVI Broadcaster DL is an Ethernet network device that can be automatically
configured to connect to networks that support DHCP addressing or it can be
manually configured to use static IP addressing to connect to the network. It
supports a 100Mbps Ethernet connection. For more advanced users, the DVI
Broadcaster DL can also be configured prior to connecting it to the network. This is
done by connecting a workstation directly to the DVI Broadcaster DL using its
Ethernet port.
Upon connecting to an Ethernet network, the DVI Broadcaster DL can be configured
and operated through an easy to use web-based administration interface.
Once properly configured, the DVI Broadcaster DL device can broadcast the video
source and the optional audio source over a wired Ethernet cable connected to the
network.
Viewers are simply provided with a URL in order to watch the desired broadcast
stream. Additionally, the DVI Broadcaster DL allows content producers to also
record the broadcast to .AVI or .MOV formatted files.
The Epiphan DVI Broadcaster DL comes with a 4 GB internal solid-state memory for
recording broadcasts which provides buffering such that in the event the network is
experiencing slow transfer rates, no captured data will be lost. In addition to this

Physical Attributes

DVI Broadcaster DL User Guide
built in flash storage, recorded video files can be archived to a network storage
device such as a FTP server or copied to an inserted USB flash drive.
The DVI Broadcaster DL can support streaming over HTTP, RTSP, peer-to-peer RTP
connection, multicast RTP and a Content Distribution Network (CDN) broadcast
network. The decision on how to stream a broadcast will depend on the answers to
the following questions as well as other design decisions. What is the number of
expected viewers? How are the viewers going to stream the broadcast? What are
the network capabilities on the broadcast side and on the viewer side? Should a
Content Distribution Network be used? For further details on broadcasting
strategies, please refer to Streaming.

3.2.5 Power over Ethernet (PoE) Injector
The DVI Broadcaster DL incorporates a Power over Ethernet (PoE) technology. PoE
delivers both data and electrical power to an Ethernet enabled device using a single
Ethernet cable. This eliminates the need for the DVI Broadcaster DL to be situated
close to a power outlet. This allows more freedom in its placement.
PoE injectors supply or inject direct current (DC) power through network cables to
power network devices.
4Getting Started
4.1 Supplying Power to the DVI Broadcaster DL
To provide power to the DVI Broadcaster DL, plug the provided PoE adapter into a
10/100Base-T Ethernet network using an Ethernet cable. This network must be
running the TCP/IP protocol.
If your network does not provide Power over Ethernet, connect the DVI Broadcaster
DL to an AC power outlet with the PoE adapter/injector connected to an Ethernet
cable and plugged into the DVI Broadcaster DL’s RJ45 Ethernet port.
Regardless of the power source once connected, the DVI Broadcaster DL now
powers up. Its power and activity LEDs will now light up following their start up
sequence.
4.2 Confirm Input Signal is Received
Confirming that the input signal is being received by the DVI Broadcaster DL can be
done once the DVI Broadcaster DL has been powered on and the input source has
been started.
First, check that the DVI Broadcaster DL’s red LED is blinking. A blinking LED
indicates that the DVI Broadcaster DL is capturing images. If the red LED does not
start flashing, check the input source to ensure that it is transmitting a signal.
Additionally, check that a cable from the input source to the DVI Broadcaster DL is
connected correctly.
Note that you can check whether the DVI Broadcaster DL is transmitting an audio
signal only in a live stream or when you open a recorded file.
