DVI Broadcaster DL User Guide
2 Overview
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
Page 9
Physical Attributes
5
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.
4 Getting 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.

5 Video Formats and Standards
The DVI Broadcaster DL supports broadcasting 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 DVI Broadcaster DL, video codec for streaming is selected by an
administrator. After this action the system creates a list of available streaming
formats for this codec. Users can view the broadcast in any available format
depending on their preference. Moreover, multiple users can view the same
broadcast in different formats. The list of formats available for the selected
combination of video and audio codecs displays on the Info page of the Web admin
interface.
The DVI Broadcaster DL can stream video using Flash (H.264), ASF (MPEG4 or H.264
codecs), Motion JPEG, RTSP (MPEG4 or H.264 codecs) or MPEG-TS (H.264). 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 called 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 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.

The MPEG Transport Stream (MPEG-TS) type supports many software and hardware
media players. This stream type conforms to H.264 standards.
Note: Media Player, browser, viewer capabilities and compatibilities are subject to
change.
6 Signal Capture
6.1 Connecting Input Sources
It is recommended that prior to powering up the DVI Broadcaster DL, the input
source is connected first. This input source can be a DVI or HDMI source. Any one of
these sources would be connected to the DVI Broadcaster DL using its DVI input
port. Audio input will be connected to the DVI Broadcaster DL Audio in port.
6.1.1 Connecting DVI or HDMI Input Sources
All DVI or HDMI input sources are connected to the DVI Broadcaster DL using the
DVI input port. How this connection is made and using which cable is dependent on
the input source.
DVI input sources are connected using the DVI to DVI cable.
HDMI input sources are connected using the HDMI to DVI adapter. These sources
should only be non-copy protected content.
Note that an HDMI signal containing audio will not be captured.
6.1.2 Connecting Audio Input Sources
All audio sources are connected to the DVI Broadcaster DL using the audio input
port.
6.2 Frame Grabber Adjustments
A frame grabber is an electronic device that captures individual still frames from a
digital video stream and transmits them in a digital form. An Epiphan frame grabber
is a subsystem component in the DVI Broadcaster DL and can be configured
separately. From the Web admin interface, select Frame Grabber from the main
menu to configure Frame Grabber adjustments.
Page 24
Signal Capture
20
DVI Broadcaster DL User Guide
Normally, making manual image adjustments should not be necessary. This means
that there are no default Frame Grabber adjustment settings. However, special
requirements may exist that produce image quality problems that can only be fixed
by making image adjustments.
The Frame Grabber adjustments page within the Web admin interface contains
most of the information needed to make image adjustments. This includes a brief
description of the effect created as a result of each adjustment and the adjustment
range.
To make an adjustment, add a value to one or more fields and select Apply.
To clear any adjustments, delete the value from one or more fields and select Apply.

Enhanced compatibility
mode (h.264 slicing for
RTP)
This parameter provides operating stability if the
transmitted video/audio stream is not quite supported
by the viewer’s equipment.
When this parameter is activated, each picture is
subdivided into one or more slices. The slice is given
increased importance in H.264 as the basic spatial
segment that is independent from its neighbours. Thus,
errors or missing data from one slice cannot propagate
to any other slice within the picture.
The following streaming settings can be made:

parameter allows how the date and time will be displayed.
Click on Show substitutions and use the Format
substitutions commands to select the desired date and
time format. The commands are described in a table
below.
If time labeling is not required, leave this field blank.
Frame size
Select a frame size from the drop down list to limit the
width and height of the video image. If the video source is
sending resolutions larger than the resolution limit
configured, the video image will be scaled to the
resolution limit. Limiting the frame resolution can help to
reduce bandwidth usage.
Key frame interval
Controls the number of frames. Key frames define the
starting and ending points of any smooth transition.
Limit frame rate
Enter a value in terms frames per second. This field is
used to set a frame rate that is lower than the maximum
frame rate at which the DVI Broadcaster DL can capture
images. Reducing the frame rate reduces the number of
images being captured by the device. Decreasing the
frame rate can help to reduce bandwidth usage.
Bitrate
Enter a DVI signal bitrate. A lower bitrate produces lower
quality videos and smaller file sizes. A higher bitrate
produces better quality videos and larger file sizes.

7.3 Common Settings
The following common parameters can be additionally specified:
Table 9 Common settings
Rate control mode
Used for H.264 and MPEG4 codecs. It specifies the
bitrate encoding for the signal. Select one of the
following:
- Low Delay
Means Constant Bitrate Encoding (CBR) will be used.
CBR is useful for streaming multimedia content on
limited capacity channels since it is the maximum bit
rate that matters, not the average. Therefore, CBR
would be used to take advantage of all of the
channel capacity.
- Storage
Means Variable Bitrate Encoding (VBR) will be used.
This produces a better quality-to-space ratio
compared to a CBR file of the same data. VBR files
vary the amount of output data per time segment
and the FPS value may be lower.
Stream port
The number of the port being used to stream the
broadcast. This value would be used along with the URL
to access the broadcast. In the case where there are two
streams because Independent streaming is being used,
this value remains the same for both of the URLs being
used.
In case of RTSP streaming this value is not considered.

There are several decisions that need to be made when planning the creation of a
broadcast, besides its exact content of the broadcast. Will the broadcast include an
audio component coming from an analog audio source? What video format to use,
what video standard to use, how to stream the broadcast are all questions that have
to be answered when creating a broadcast. Most of the answers depend on the
intended audience of the broadcast, how are the viewers going to view the
broadcast, and how many simultaneous viewers are expected to view the
broadcast? Where are the viewers located in relation to the where the broadcast is
Page 34
Streaming
30
DVI Broadcaster DL User Guide
being streamed? What are the performance expectations? These are the types of
questions that will determine the overall design of the broadcast.
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 System can be
used in this design.
The DVI Broadcaster DL 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 DVI Broadcaster DL, video codec for streaming is selected by an
administrator. After this action the system creates a list of available streaming
formats for this codec. The figure below is representation of the protocol stack
diagram showing how the video data is processed.
Figure 14 Protocol Stack Diagram
How the broadcast will be delivered to its viewers depends on the number of
intended viewers and where the viewers are in relation to where the broadcast is
originating. Are they on the same LAN or will they be accessing the broadcast from
Page 35
Streaming
31
DVI Broadcaster DL User Guide
an external network? The answers to the above questions will help decide the
delivery method of the broadcast.
The DVI Broadcaster DL can support streaming over HTTP, RTSP, peer-to-peer RTP
connection, multicast RTP, MPEG-TS, and a Content Distribution Network (CDN)
broadcast network. Each broadcast delivery method will be now discussed in more
detail.
8.1 HTTP or RTSP Streaming
For HTTP or RTSP streaming the only information required to view the broadcast is
the URL of the broadcast. The DVI Broadcaster DL is ready to go straight out of the
box, without any additional settings. If your broadcast needs to be accessed by
many clients, use a Content Distribution Network as explained in the Using a
Content Distribution Network section.
8.2 Using a Content Distribution Network
A content delivery network (CDN) is a system of computers or servers that ingest an
incoming stream source and rapidly provides this content to numerous users by
duplicating the content on multiple servers and directing the content to users.
CDN distributes a heavy load of traffic to multiple locations in order to avoid
congestion on a network that could impact a user’s Internet experience. A CDN is
highly scalable and can make financial sense to website owners as you will not need
to pay for additional server hardware or routing should your website traffic start to
increase or even decrease. The use of CDN technology has obvious advantages to
those users whose broadcasts have large audiences from locations all over the
world. If dozens or hundreds of viewers happen to select the same Web page or
content simultaneously, the CDN sends the content to each of them without delay
or time-out.
To stream to multiple users, the System can be configured as a client to CDN. Please
click http://epiphan.tv/cdn-partners.php to view the list of CDN providers preferred
by Epiphan. By connecting to a CDN server, the broadcast from the DVI Broadcaster
DL can be streamed to multiple viewers. By using a CDN, the maximum number of
Page 36
Streaming
32
DVI Broadcaster DL User Guide
concurrent clients is increased, while at the same time reducing the load on the
uplink internet connection.
CDN streaming is a very effective approach when you are broadcasting streams from
the Epiphan solutions and want to add scalability to your broadcast. The DVI
Broadcaster DL features the Publish Stream functionality that enables you to stream
the broadcast either via Epiphan’s portal or CDN providers to multiple viewers. You
must use the H.264 codec for CDN streaming.
Using CDN it is possible to set a user name and a password for the broadcast. Each
viewer will have to request it from you before viewing the broadcast. This function
allows you to manage access to your content ensuring visibility only to the
appropriate and authorized viewers.
Figure 15 Using a CDN Service Increases Scalability of Concurrent Viewers
The Publish Stream functionality allows for directing captured video and audio to
servers or clients using one of the available stream modes. The following options are
available:
- Disabled. If this option is enabled, you cannot send multicast RTP stream,
perform CDN broadcasting or stream video to Epiphan’s portal.

- using RTP/UDP push. This option allows for IP multicast broadcasting.
- using MPEG-TS UDP push. This option allows for IP multicast broadcasting
of files in the MPEG-TS format in case when the UDP transportation
protocol is used.
- using MPEG-TS RTP/UDP push. This option allows for IP multicast
broadcasting of files in the MPEG-TS format in case when the RTP/UDP
transportation protocol is used.
These options and settings to be performed are discussed further.

DVI Broadcaster DL User Guide
8.2.3 Setting up Multicast from Publish Stream
A multicast RTP stream provides a one-to-many broadcasting framework. In a
multicast RTP configuration, the DVI Broadcaster DL sends a packet only once to a
router that supports multicasting. This router then distributes the packets to all
intended viewer nodes using a multi-cast protocol.
A multicast address is associated with a group of interested receivers. In IPv4,
addresses 224.0.0.0 through 239.255.255.255 (the former Class D addresses) are
designated as multicast addresses.
Sending multicast streams requires equipment that supports multi-casting,
configuring your network and enabling specific multicasting features on the DVI
Broadcaster DL. Multicast architectures are used predominantly within a high
bandwidth corporate LAN and not on Internet based architectures. Multicast RTP
streaming is not usually propagated outside the LAN though it may be propagated
through VPNs connecting several LANs. Multicast transmission is available during
RTP streaming.
RTP/UDP Push streaming allows you to direct video to a server or client and
generates an SDP file containing the stream description. SDP files can be stored on a
streaming server, or opened by video players.
To use this option:
1. Select Publish Stream from the main menu.
2. Select RTP/UDP Push from the drop-down list.
3. Enter a destination multicast IP address. At this target point the broadcast
will be viewed.
4. Specify the numbers of the video and audio ports where the broadcast will
be received.
5. Click Apply.
6. An SDP file is now generated. It is available in the Info section of the Web
Admin interface. You can either save an SDP file on your local machine or
provide the link to SDP file to your audience.

8.3 UPnP
The DVI Broadcaster DL supports a set of networking protocols named Universal
Plug and Play (UPnP). It allows you to discover a presence of the functioning DVI
Broadcaster DL on the network using a device such as media player connected to a
TV set. Once the DVI Broadcaster DL is connected to a network, it automatically
establishes working configuration with the media player and can share the data
stream.
To use the UPnP functionality, you must configure the following file and streaming
settings in the Web Admin interface:
Video codec
H.264
Audio codec
MP3 or AAC. Alternatively you may configure UPnP without
selecting any audio codec.
File type
MPEG-TS – to obtain access to the files recorded earlier.
This functionality is enabled in the UPnP section of the Web Admin interface. The
media player identifies the DVI Broadcaster DL as a media server. In the
explanations below the UPnP settings are illustrated by the example of the media
player Asus O!Play.
To establish UPnP connection:
1. Set up the DVI Broadcaster DL and start streaming/recording.
Page 46
Streaming
42

10.3.3 Performing Network Diagnostics
A tool in the Network section of the web interface combines the functionality of the
traceroute and ping programs in a single network diagnostic tool.
Traceroute is a computer network diagnostic tool for displaying the route or path
and measuring transit delays of packets across an Internet Protocol (IP) network.
Ping is a computer network administration utility used to test the reachability of a
host on an IP network and to measure the round-trip time for messages sent from
the originating host to a destination computer.
This tool investigates the network connection between the host that the DVI
Broadcaster DL runs on and a user-specified destination host. After entering the URL
Page 77
System Administration
73
DVI Broadcaster DL User Guide
or IP address, click either ping or traceroute. If ping is clicked, the tool determines
the reachability of the user-specified host. If traceroute is clicked, the route and
measures transit delays of packets is displayed. As it does this, the tool displays
statistics about each machine.

11 System Administration
11.1 Setting the Date and Time
The date and time can be set manually or Time synchronization can be enabled on
the DVI Broadcaster DL. Configuring how the date and time is managed on the DVI
Broadcaster DL is done by selecting Date and Time from the Web admin interface’s
main menu.
Page 78
System Administration
74
DVI Broadcaster DL User Guide
Clicking Enable Time Synchronization on the Date and Time page, results in the date
and time being received from a public network time protocol (NTP) server. This is
done by having the DVI Broadcaster DL connect to the server over the Internet. NTP
uses UDP and port 123. The default NTP server is time.nrc.ca. This should be
changed to a NTP server that is recommended for your location. This information
should be available from your network administrator.
For more information about NTP, including a list of recommended NTP servers, refer
to the following webpage: The NTP Public Services Project.
To get the correct time from the NTP server, ensure that the correct Time Zone for
the location of the DVI Broadcaster DL is selected.
If the DVI Broadcaster DL device cannot connect to the Internet and there is an
RDATE server on the network, you can set time synchronization to use RDATE (as
defined by RFC 868). Contact your network administrator for the address of the
RDATE server and enter the RDATE server IP address into the Server IP Address field.
In both cases, how often the date and time is updated can be configured. The Time
Update interval can be every 1, 6, 12, or 24 hours.

11.2 Configuring Administrator Access
Initial factory settings provide no password for the administrator user. For security
reasons, a password to control access to the administration functions should be
added.
The administrator user’s password can be added or changed at any time in the
Access Passwords section of the Web Admin interface.
If you lose or forget the admin password you can reset the device to its factory
default setting. See Restoring the DVI Broadcaster DL Default Factory Configuration
in order to reset the device to factory defaults.
11.2.1 To add or change the Administrator password

2. Select Access Passwords. The password fields should be blank.
3. Select Apply without adding characters to the password fields. The password is
deleted.
11.4 Configuring Viewer Access
Controlling viewer access to a broadcast can be done in two different ways. The first
is to assign a password to the DVI Broadcaster DL’s viewer password and the second
is to enable IP Address based authentication. By default the viewer user does not
have a password to control access and no IP Address based authentication is
enabled. Viewers have access only to Live View functionality in browser or direct
streams in player.
Figure 54 Changing the Viewer Password
11.4.1 To add or change the viewer password
Used to add or change the password associated with the viewer user. The viewer
access password is the same for all viewers until it is changed. Any viewer that
Page 83
System Administration
79
DVI Broadcaster DL User Guide
knows the password will continue to have access until the password is changed. It is
good practice to change the password each time there is a change in the users that
should be authorized to access the broadcast. Please contact your network security
administrator with respect to password management required for your applications.
Once a viewer password is configured, participants must obtain the current viewer
password in order to log in. The user name is always the same: viewer. It cannot be
changed. If the viewer password is changed during a broadcast, the broadcast is
interrupted and all viewers will be required to re-log in using the new viewer
password in order to continue receiving the broadcast. Depending on how the
viewer is receiving the broadcast, this will involve clicking the refresh button in the
viewer’s browser or clicking on the play button in the viewer’s media player.
1. Log into the Web admin interface.
2. Select Viewer Access.
3. Enter and repeat the new password. The password is case sensitive and can
include up to 255 ASCII characters.
4. Select Apply.
5. Distribute or communicate the viewer access password to authorized viewers
of the broadcast.
11.4.2 Configuring IP-based Authentication for Viewers
This function allows the option of providing access to the broadcast to a large
number of users without having each individual user log in with the viewer
username and password. This is done by configuring individual IP addresses or a
range of IP addresses that are either granted access or denied access to the
broadcast. Once set up, users can access the broadcast just by clicking on a supplied
link. The administrator for the broadcast would continue to access the Web admin
interface using the administrator user credentials to access all features.
Figure 55 IP-based Authentication
If any addresses are specified in the Allow IP’s field, access to the broadcast will be
allowed only for these addresses.
Page 84
System Administration
80
DVI Broadcaster DL User Guide
If any addresses are specified in the Deny IP’s field, access to the broadcast will be
forbidden for these addresses and allowed for all other addresses.
The list of denied IP addresses has a higher priority over the list of allowed IP
addresses. An example of how this is implemented would be the following:
1. In the Deny IP’s field enter 172.20.1.20-172.20.1.30.
2. In the Allow IP’s field enter 172.20.1.22, 172.20.1.33.
Access to the broadcast will be forbidden for the entire subset of addresses -
172.20.1.20-30.
The set of users must have a fixed IP address or a range of IP addresses through
which they connect to the internet. Individual computers may have dynamic serverassigned addresses but as long as they use a gateway with a static address to access
the internet, this feature can be configured
IP authentication is primarily about convenience, rather than extra security. The
level of security is comparable with that of a password-based authentication. Bear in
mind that anyone who has access to a computer within the specified range will be
able to access the broadcast without having to provide log in credentials. Also it is
probably not possible to restrict access to a single computer since in most networks
a number of computers share a single gateway to the internet.
The table below shows the fields used in configuring IP-based authentication for
viewers.
Deny IP’s
Enter individual IP addresses separated by a comma or a range of IP
addresses that are denied access to the broadcast. To specify a range
of addresses, use a hyphen (-).
Example 1: 172.20.1.20, 172.20.1.32
Example 2: 172.20.1.1-100
Allow IP’s
Enter individual IP addresses separated by a comma or a subset of IP
addresses that are granted access to the broadcast. To specify a range
of addresses, use a hyphen (-).
11.4.3 Delete the Viewer Password
The viewer password can be deleted if viewers are not required to enter a password
to access the broadcast.

15 Configuring Remote Support
The DVI Broadcaster DL uses remote support settings to communicate with the
Epiphan maintenance server. When enabled, communicating with the maintenance
server allows Epiphan to review the device configuration, firmware version, and
other basic operating parameters. If you contact Epiphan Support for help with the
DVI Broadcaster DL, the support team can use this maintenance information to help
remotely troubleshoot the problem.
The DVI Broadcaster DL device does not send private information to the Epiphan
maintenance server, just basic operation and configuration information. The amount
of traffic sent to the Epiphan maintenance server is small and should not affect the
network or Internet throughput.
By default, communication with the Epiphan maintenance server uses a TCP port 30.
The default address of the Epiphan maintenance server is epiphany.epiphan.com.
The DVI Broadcaster DL must be able to find a DNS server to resolve the default
address and then must be able to connect to this address on the Internet using TCP
port 30. If the DVI Broadcaster DL’s network settings are set to use DHCP, it gets the
Page 95
Configuring Remote Support
91
DVI Broadcaster DL User Guide
address of the DNS server from the DHCP server. If network settings are set to use a
static IP address, the IP address of the DNS server must be entered. This IP address
can be retrieved from your network administrator.
If you have a firewall or some other device protecting the network from the Internet
and you would like to enable remote support, the configuration of this device may
have to be changed for the DVI Broadcaster DL to connect to the Epiphan
maintenance server. Contact your network administrator for assistance.
Remote support is enabled by default. Use the Maintenance section in the Web
admin interface to access the remote support settings and refer to the following
diagram and table for more details on how to configure this feature.

16 Disk Check
A disk maintenance schedule can be set up for checking the DVI Broadcaster DL’s
hard disk for errors. The hard disk maintenance schedule includes running a disk
check after either a configured number of device restarts or after a configured
number of months of operation. This is configured on the Disk Check page which is
opened by selecting Disk Check from the Web admin interface’s main menu.
This page allows the number of the Recorder restarts before a disk check is to be
performed and the number of months to lapse prior to a disk check to be
configured. The system will trigger a disk check based on these values and based on
whichever event occurs first. The actual disk check process will be run the next
time the DVI Broadcaster DL restarts. The disk check occurs during system startup
and can cause a lengthy delay in starting up the device.
Page 98
Disk Status Information

DVI Broadcaster DL User Guide
Alternatively on the same page, select Check disk now to immediately perform the
disk check. Clicking this button causes the device to stop recording and to check the
disk immediately. The disk check process can take a few minutes. The DVI
Broadcaster DL automatically resumes recording after the disk check is complete.
Results of the disk check are not displayed unless errors that cannot be corrected
are found.
Figure 64 Configuring the Disk Maintenance Schedule
17 Disk Status Information
In the Disk status section of the Web admin interface’s main menu, the total
amount of space available on the DVI Broadcaster DL’s solid state memory in GB is
listed. Additionally, the used and available space in GB, and the amount used as a
percentage of the total amount of space on the disk is displayed for quick reference.
If the DVI Broadcaster DL is running low on disk space the administrator can delete
files. The administrator can also configure automatic file uploads to keep the DVI

18 Configuring using a Third-Party Application
The DVI Broadcaster DL can be configured and managed with the third-party
applications or with a script that sends commands to the DVI Broadcaster DL as
URLs. Please contact Epiphan for the most recent updates to the API.
This chapter describes:
- Serial port configuration;
- RS-232 commands;
- Syntax for HTTP API Commands;
- Keys for HTTP API Commands;
- and finally provides some examples.
18.1 Serial Port Configuration
The System’s serial port configuration has the following settings:
Parameter
Value
Speed
19200 bps
Data bits
8
Parity
None
Stop bits
1
Flow control
Hardware
18.2 RS-232 Commands
The DVI Broadcaster DL implements an RS-232 interface allowing for the easy
integration with existing control room and board room equipment.
Some of the commands require channel name as an argument. Channel name
should be separated from the command name by a period – “.”. Either a channel
name or a channel index can be specified. An empty channel name can be provided
for some commands. In this case this setting is interpreted as all channels. If more
than one channel has the same name the command will apply only to one channel,
so the channel index should be used instead.

Table 18 Serial Interface commands and Status Report commands and description
STOP
Stop recording
START
Start recording
SNAPSHOT
Take snapshot (must be MJPEG)
GET.<key>
Get value of a broadcasting parameter <key>.
Please refer to section Broadcasting Setup Keys for
details. The command varies depending on the
stream as shown below.
SET.<key>=<value>
Set value of a broadcasting parameter. Parameter
values containing spaces must be enclosed in
quotation marks (either single or double). New
values might not take effect immediately and will
be lost after the reboot unless SAVECFG command
is issued later. The command varies depending on
the input stream as shown below.
SAVECFG
Save parameters values modified by SET command.
STATUS
Report status of recording service. Note that the
device reports the status information only at the
moment when the status is updated.
Status values are: "Running", "Stopped",
"Uninitialized".
FREESPACE
Report free space on the data partition, in bytes.
RECTIME
Report elapsed time for the current recording file.
If any of the START commands are given while a recording is already in progress, the
current recording will be stopped and a recording with the new settings will be
started. The DVI Broadcaster DL periodically reports its status back using the
following messages:
Status Line Value
RECTL STATUS {UP <time>|DOWN
<time>|UNKNOWN}
Status of the recording
RECTL MICVOLUME <0-100> Level of line-in amplification (percents)
RECTL PCMVOLUME <0-100> Level of line-out amplification (percents)
