GOSTREAM BRD Indicators and Switches
The GOSTREAM BRD card can be installed in the 20-slot DFR-8321 or OG-3 frames. The 10-
slot DFR-8320 frame is not supported. Prior to installing the card, first install the corresponding
rear panel I/O module.
Rear I/O Panel Indicators
There are two types of rear I/O panels available for the GOSTREAM BRD, depicted below.
Both types include one ASI input, one ASI output, one composite output and one SDI output on
standard BNC connectors, one HDMI output and one 100/1000 Mb/s Ethernet port on a standard
RJ-45 connector. The panels differ only on the type of analog audio output: one type has
balanced audio on terminal blocks, and the other type has unbalanced audio on RCA connectors.
The ASI input port has a green indicator LED, with the following states:
LED off: ASI port is disabled.
LED flashing once every 3 seconds: the ASI port is not locked to a signal (i.e., there is
no input signal).
LED flashing once per second: the ASI port is locked to a signal.
The ASI output port has a green indicator LED, with the following states:
LED off: ASI port is disabled.
LED flashing multiple times per second: ASI port is transmitting packets.
The Video output ports share one green indicator LED, with the following states:
LED off: the BRD is not currently decoding a stream. There may be a valid video signal
in the output, but it does not correspond to a decoded stream.
LED flashing once per second: the BRD is currently outputting an SD stream on the
selected output ports.
LED flashing multiple times per second: the BRD is currently outputting an HD stream
on the selected output ports.
The Gigabit Ethernet port has two indicator LEDs, with the following states:
Green LED:

Front Panel Default Switch
The front panel has a recessed switch that can be used to restore the unit to its defaults. Use a
pen or a small screwdriver to press this switch.
If the switch is pressed during normal operation, the control port IP address, mask and gateway
are restored to the following factory default settings:
IP Address: 192.168.1.30
Subnet Mask: 255.255.255.0
Gateway: 192.168.1.1
The STAT front panel indicator will change colors for about 3 seconds to acknowledge the
change. Note that this operation may glitch the video.
If you press and hold this switch when the unit is powered off, and then power up the unit while
holding the switch, the following actions will be performed:
The control IP address, mask and gateway are reset to the factory defaults as described
above.
The unit configuration is cleared.
The unit reverts to the factory-installed firmware.
As before, the STAT LED will temporarily change color to acknowledge the command. When it
changes color, you can release the switch. You can use this feature in the unlikely event of a
corrupted firmware upgrade or a corrupted configuration.
19
GOSTREAM BRD Operation and Management
The GOSTREAM BRD is configured using the free Dashboard application, which is available
for Windows, Apple OS X, and Linux. Dashboard can be downloaded from this link:
http://www.opengear.tv/dashboard-software
3
The GOSTREAM BRD user interface is depicted below. As with any openGear® card, it is
divided into a statistics panel on the left, and a configuration panel on the right. Each panel has
multiple tabs, corresponding to the various functions in the card. Note that the Card State alarm
indicator is also reflected in the green/red Status LED in the front of the board or the Status
button in the GOSTREAM BRD. The Status LED will be green when Card State is green or
yellow, and will be red when Card State is red.
For the remainder of this manual, all described features are available for the GOSTREAM BRD
card and stand-alone model unless explicitly stated. Both products are referred to as the BRD
decoder.
The following tabs are available:
Product: this tab provides general information on the card, including firmware version,
uptime, temperatures, and other parameters. It appears only on the Statistics panel.
Network: this tab is used to configure the IP addresses and network information for the
Ethernet ports. The statistics side of the panel includes some additional information such
as link state.
ASI Input: this tab is used to configure/monitor the ASI Input port.
ASI Output: this tab is used to configure/monitor the ASI Output port.
Decoder: this tab is used to configure/monitor the decoding function.
IP Outputs: this tab is used to configure/monitor the ASI to IP turnaround function.
Monitoring: this tab is used to configure the decoder stream monitoring function, and to
inspect any monitoring alarms.
Admin: this tab is used for general administrative functions, such as firmware upgrades,
licensing, logs, and configuration management.

21
Product Tab
The Product Tab contains basic information about the BRD.
The following information is available:
Build Date: Date the firmware image was built.
Supplier: Niagara Video Corporation.
Product: GOSTREAM BRD.
Software revision: This indicates the firmware revision currently running. The format is
Major Version Minor Version Build Number.
22
DSP version: This indicates the firmware revision for the decoding subsystem. The
format is Major Version Minor Version. DSP firmware will only occasionally be
updated by Niagara Video.
Serial Number: This is the serial number of this particular BRD card or stand-alone unit.
Hardware Version: This indicates the board version number. All board versions are
functionally equivalent.
Rear Module: This indicates the status of the Rear I/O Module. It can have one of the
following states:
o OK: The Rear Module is the correct module for the GOSTREAM BRD. In the
GOSTREAM BRDc/d this indicator will always indicate OK.
o Not Installed: The GOSTREAM BRD is not connected to a rear module. The
card is operating normally, but it will not be useful as there are no input and
output connections to it.
o Wrong Module: The GOSTREAM BRD is connected to a rear module that
was not designed for it (most likely from another openGear™ vendor).
Depending on the signals present on that module, there may be a small chance of
damage to the GOSTREAM BRD; Niagara Video recommends that this situation
be rectified immediately. This alarm will cause the front status LED to turn red.
Analog Audio Output: The BRD can be fitted with either balanced or unbalanced
analog audio outputs. The openGear GOSTREAM BRD can be ordered with either
balanced or unbalanced rear I/O panels. The same card will support both types. The
stand-alone GOSTREAM BRDc/d factory-configured with balanced or unbalanced audio
at the time of ordering. This parameter indicates the type of analog audio installed with
this decoder.
Card Uptime: Indicates how long the card has been running since it was last rebooted.
Ambient Temperature: Temperature, in degrees centigrade, of the air intake of the card
(measured at the front edge of the card).
Internal Temperature: Temperature, in degrees centigrade, at the back of the card.
MDP Core Temperature: Temperature, in degrees centigrade, of the core processing
element.
Card Power (W): Indicates the current power draw of the unit, in watts.
The openGear™ frame is designed to operate in environments with up to 40
o
C ambient. There is
typically a 5
o
C temperature raise from the external ambient to the “Ambient Temperature”
measured by the GOSTREAM BRD. If that measurement is at 45
o
C or higher, action must be
taken to cool down the ambient temperature. The GOSTREAM BRD will log excessive
temperature events.
The GOSTREAM BRD stand-alone version is designed to operate in environments with an
ambient temperature between 0 and 50
o
C.
23

If the BRD has connectivity to the Internet and there is no DNS in your local network, Niagara Video recommends
using the Google public servers at addresses 8.8.8.8 and 8.8.4.4.
24
IGMP Version: The GOSTREAM BRD implements the IGMP protocol for multicast
reception. This parameter controls the version of the protocol to be used.
o Auto-Detect: The BRD will attempt to auto-detect the IGMP version in use by
inspecting the Group Membership Requests received from the router. It defaults
to IGMP Version 3 if no messages are received.
o IGMP Version 1: Force the use of Version 1 only (not recommended)
o IGMP Version 2: Force the use of Version 2 only
o IGMP Version 3: Force the use of Version 3 only
Interface speed: Configures the speed of the interface. The following modes can be
selected:
o Auto-Negotiate: The Ethernet port will auto-negotiate the speed. All modes are
available.
o 100 Mb/s Full-Duplex: Force the port to 100Mb/s Full-Duplex mode. Note that
the port will still perform auto-negotiation, but it will only advertise this mode.
o 1Gb/s Full-Duplex: restrict the operation to 1Gb/s Full-Duplex mode. Note that
the port will still perform auto-negotiation, but it will only advertise this mode.
Interface Settings: If you make any changes to the IP Address, Subnet Mask, Default
Gateway and/or DNS fields, the Apply and Cancel buttons become active. The changes
only take effect when you press the Apply button. Pressing the Cancel button reverts the
fields back to their original values. Note that the BRD will check the consistency of the
data entered and will reject invalid combinations. Once the Apply button is pressed, a
status message appears just below the Cancel button, as follows:
Network Statistics Tab
The Network Statistics Tab reports the current IP configuration the Ethernet port, as well as its
link state and running status.
25
The following parameters are reported in the Network Statistics tab:
Alarm on Link Loss: Reports the current setting of this parameter.
IP Address: Reports the current IP Address for the port.
Subnet Mask: Reports the current Subnet Mask for the port.
Default Gateway: Reports the current Default Gateway for the port.
DNS Server 1, DNS Server 2: Report the current DNS IP addresses.

board will also be red. If Alarm on Link Loss is set to No, this indicator will still be
red, but the alarm will not propagate.
Link Speed (Mb/s): This parameter reports the actual speed negotiated with the switch
for the port. If the port has no link, the value reported here is zero.
MAC Address: This reports the MAC address of the Ethernet port.
26
ASI Input Port Tab
The BRD decoder has one fixed-function ASI Input Port. This tab is used to configure and
manage it.
ASI Input: Configuration Tab
The Configuration Tab for the ASI inputs is shown below:
The Configuration tab is divided into two areas:
The ASI Input table, which displays an overview of the ports. It contains the following
fields:
o Status: Indicates the current status of the port. The possible values are:
Locked: the port is enabled and locked to a valid ASI signal.
Unlocked: the port is enabled, but has no signal.
Disabled: the port is disabled by user configuration.
o Size: Indicates the detected ASI transport packet size (188 or 204 bytes). If the
port is disabled or unlocked, this field will show a value of 0 (zero).
o TS Bit Rate (b/s): Measured transport stream bit rate, in bits/second.
o Port Name: All BRD ports can be assigned a user-defined name, which is
displayed here. The default name is ASI Input 1.
o Edit: This button, when clicked, brings up the configuration area of the port.
The configuration area of the port, which is accessed by clicking on the Edit button, as
shown below.
27
Click here

The following parameters are available:
Port Name: All BRD inputs and outputs can be assigned a user-defined port name. This
name is used to identify the port later when making connections. Use any descriptive
name suitable for your application, or accept the default.
Enabled: the ASI Input can be enabled/disabled using this parameter. When the port is
disabled, the corresponding LED in the front and back panels stays off.
Once the desired configuration is entered, click on the Apply button to have them take effect.
This will cause the changes made in the Configuration Parameters to be implemented. Clicking
on the Cancel button will discard any changes.
ASI Input: Statistics Tab
The Statistics Tab for the ASI Ports provides a quick visual summary status for the ports. A
sample is depicted below:
The ASI Input Port indicator can have the following values:
RX Locked: The port is locked to an input signal.
RX Disabled: The port is disabled.
RX Unlocked: The port is not locked to any signal.
28
ASI Output Port Tab
The BRD decoder has one fixed-function ASI Output Port. This tab is used to configure and
manage it.
ASI Output Port: Configuration Tab
The ASI Output Configuration Tab is show below:
The ASI Output table is always displayed, and its columns are:
Status: Indicates the port status. It can contain the following values:
o OK: Port is operating normally.
o Unlocked: Port is unlocked. This status means that the port is in Automatic mode
and it has no input.
o Overflow: This means that the ASI Output is in Manual mode, and the configured
bit rate is insufficient to carry the input connected to it. This situation will raise
an alarm.
Size: Indicates the transport packet size, in bytes.
Source: Indicates the current source for the data being outputted in the port.
TS Bit Rate (b/s): This reports the actual transport stream bit rate, in bits/second.
Port Name: This reports the configured Port Name.
Edit Button: Clicking on this button allows reconfiguration of the port. The ASI Port
Configuration screen appears, with the settings for the port.
Clicking on the Edit button will cause the configuration area of the port will to open, as depicted
below. The configurable parameters are:
Port Name: All BRD inputs and outputs can be assigned a user-defined port name. This
name is used to identify the port later when making connections. Use any descriptive
name suitable for your application, or accept the default.
Packet Size: Select between 188 or 204 bytes.
ASI Rate: The available selections are:
o Manual: In this mode, the ASI output bit rate is manually set. If the content
routed to the port exceeds the configured bit rate, packets will be dropped and the
port will raise an alarm.
o Automatic: In this mode, the ASI output bit rate is automatically set by the BRD
to match the source connected to the port.
29
Bit Rate: This field is only shown if the ASI Rate control is set to Manual. Enter the
desired bit rate in bits/second.
Source: This field indicates the source for the ASI Output content. For the current
firmware version, the only option is the ASI Input content. Future versions of the
firmware will offer additional options.
Once the desired configuration is entered, click on the Apply button to have them take effect.
This will cause the changes made in the Configuration Parameters to be implemented. Clicking
on the Cancel button will discard any changes.
ASI Output Port: Statistics Tab
The Statistics Tab for the ASI Output Port provides a quick visual summary status. An example
is depicted below.
The ASI Port indicator can have the following values:
TX OK: The port is operating normally in transmit mode (ASI Output).
TX Overflow: The port is in manual bit rate setting, and the connected bit rate is
excessive. The Dashboard Card State will be red and the Status LED in the front of the
board will also be red. To correct this problem, either externally reduce the input bit rate,
or increase the ASI output bit rate, or configure the port in Automatic mode. If this
alarm is active, data is being dropped.
TX Unlocked: The port is in transmit mode, automatic bit rate, and there is no data
rate coming to it. Any downstream ASI receivers will lose lock.
30
Decoder Tab
The Decoder Configuration Tab contains the configuration parameters for the decoding function.
The Statistics tab provides quick feedback on the configuration and status of the decoding
process.
Decoder Configuration Tab
The decoder configuration tab is divided into two bottom tabs (depicted below):
The Configuration tab, where all the main decoder parameters are configured.
The Program Info tab, where program-specific information is displayed. If the decoder
is in HLS mode, this tab allows for manual configuration of the decoded profile.
The decoder configuration tab is divided into the following functional areas:
The Decoder Input configuration area
The Program and Audio Selection configuration area
The Output Configuration area
The Analog Audio Configuration area
The Apply/Cancel buttons
The settings displayed in each of the areas will vary according to the specific configuration.
Decoder Input Configuration
The primary decoder input configuration parameter is the Source, which selects the input and
protocol from which the decoder will take its content:
The following stream sources are supported:
ASI Input: the decoder will accept content on its ASI Input port.
31
UDP/RTP Stream: the decoder will accept content on Ethernet over UDP/RTP, with
optional support for SMPTE-2022 FEC. The BRD also supports the notion of a backup
flow – if the primary flow disappears, the decoder will switch to the backup. Note that,
in the stand-alone GOSTREAM BRDc, UDP/RTP streams are only accepted in the
streaming Ethernet port.
HLS Stream: the decoder will retrieve the stream in real-time from an HTTP Live
Streaming web server.
RTMP Client: the decoder will retrieve a Flash stream from an RTMP Server, such as
the Adobe Media Server or similar.
RTMP Server: the decoder will accept a Flash stream from a publishing RTMP client.
RTSP Client: the decoder will connect to an RTSP server, such as an IP Camera, and
play the content.
Color Bars: the decoder will output standard color bars.
The remaining parameters in the Decoder Input section will depend on the Source selection.
ASI Input
When ASI Input is selected, the following control becomes available:
On Input Loss: selects the decoder behavior when the input signal disappears. If Freeze
Frame is selected, the decoder displays the last valid frame; if Go to Black is selected,
the decoder resets the signal and goes to black. The criterion for signal disappearance is
loss of tables.
UDP/RTP Stream
When UDP/RTP Stream is selected, the following controls become available:
32
On Input Loss: selects the decoder behavior when the input signal disappears. If Freeze
Frame is selected, the decoder displays the last valid frame; if Go to Black is selected,
the decoder resets the signal and goes to black. The criterion for signal disappearance is
loss of tables.
Primary Reception: select between Unicast and Multicast. In Unicast mode, the
stream must be sent to the decoder’s streaming port IP address (see the Network Tab). In
Multicast mode, the decoder will join an IP Multicast stream. When this mode is
selected, a new field appears for the multicast address:
o Primary Multicast Address: enter the desired IP multicast address. The decoder
will only accept addresses between 224.0.0.0 and 239.255.255.255 in this field.
Primary UDP Port: enter a valid UDP port. Valid values are between 1 and 65535.
Redundant Reception: if this box is checked, a backup UDP flow can be configured. If
the BRD stops receiving packets in the primary flow, it will switch to the backup. When
this box is checked, the following new fields appear:
o Flip Time (s): this configures how long the BRD will wait to decide to flip between
primary and backup streams.
o Backup Reception: select between Unicast and Multicast. In Unicast mode, the
stream must be sent to the decoder’s streaming port IP address (see the Network Tab).
In Multicast mode, the decoder will join an IP Multicast stream. When this mode is
selected, a new field appears for the multicast address:
o Backup Multicast Address: enter the desired IP multicast address for the backup
stream. The decoder will only accept addresses between 224.0.0.0 and
239.255.255.255 in this field.
o Backup UDP Port: enter a valid UDP port for the backup stream. Valid values are
between 1 and 65535.
33
o Flip Redundancy: if this button is clicked, the BRD will manually flip to the other
stream (i.e., if it is receiving from the primary, it will go to the backup, or vice-versa).
Reset Network Statistics button: when clicked, this button causes the UDP/RTP
statistics shown in the Network Tab on the Statistics area to be cleared. This is useful to
manage network performance (i.e., packet loss) from a known state.
The BRD will automatically detect UDP/RTP/SMPTE-2022 FEC (if licensed).
HLS Stream
In this mode, the decoder can access and play a stream from a web server with an HTTP Live
Streaming service. Access to the server can be either from the control or streaming ports. The
configuration parameters are:
HLS URL: Enter a valid HLS URL. The URL must start with http:// or https:// and
must end with either .m3u or .m3u8. In order to use a server name instead of an IP
address, the decoder must have at least one DNS server configured and accessible. DNS
servers can be specified in the Network Configuration Tab, or, for the GOSTREAM
BRDc stand-alone unit, also in the Control Port Configuration Tab or obtained by DHCP.
Restart HLS Playback: HLS content in the server may be a continuously-running live
stream or a VOD stream. If it is a VOD stream, the decoder will stop at the end of the
stream. Clicking on this button makes it play it again. The type of stream (Live or VOD)
is reported in the Network Tab in the Statistics area.
RTMP Client
In this mode, the decoder can access and play a Flash stream from an RTMP Server such as the
Adobe Media Server or similar. Note that not all Flash streams are supported. The BRD will
only support the following types of streams:
Video Compression: H.264
Audio Compression: MPEG-1 Layer III or AAC-LC.
An RTMP access point is defined by the following:
An RTMP URL, of the form:
rtmp[t][e][s]://servername/app
34
A stream name
The first part of the URL defines the protocol, as follows:
rtmp: standard RTMP with no security
rtmpt: RTMP tunneled over HTTP
rtmpe: encrypted RTMP using proprietary security
rtmps: encrypted RTMP over SSL
rtmpte: encrypted RTMP using proprietary security, tunneled over HTTP
rtmpts: encrypted RTMP over SSL, tunneled over HTTP
The servername field is the host name or IP address of the RTMP server to be contacted. The
app field is the application in the server that should receive the data being transmitted. Note
that, depending on the service, the app field may contain a complete path or even a set of
parameters.
The RTMP Client configurable parameters are:
RTMP Protocol: Select the protocol variant, as discussed above.
RTMP Server: Enter the host name or IP address of the RTMP server to be contacted. If
you want to use host names instead of IP addresses, make sure to configure at least one
DNS server. DNS servers can be specified in the Network Configuration Tab, or, for the
GOSTREAM BRDc stand-alone unit, also in the Control Port Configuration Tab or
obtained by DHCP.
RTMP Port Selection: If your RTMP server is using the default TCP ports for the
protocol variant, select Use Default. If your server is using a non-standard port, select
Specific Port. When Specific Port is selected, an additional field is displayed:
35
Port: This field is only displayed if RTMP Port Selection is set to Specific Port.
Configure a non-standard TCP port here.
RTMP App: Enter the application name in the server, as discussed above. Consult your
CDN or server documentation to find out what should be entered in this field.
RTMP Server URL: This informational field is automatically updated as you configure
the RTMP parameters. It displays the full RTMP URL for the primary server.
RTMP Stream: Enter the stream name for the server. Consult your server
documentation or CDN to find out what should be entered here. Some servers allow
arbitrary stream names, while others use this field for authentication and thus require
specific names.
Authentication: Some RTMP servers require username/password authentication for
access. If your server does not require authentication, select No, otherwise select Yes. If
you select Yes, additional fields are presented.
Username: Enter the username to be used for authentication.
Password: Enter the password to be used for authentication.
RTMP Server
In RTMP Server mode, the decoder waits for a publishing RTMP client to connect to it and
publish a stream, which the decoder will then play. Please note that with the current version
of the decoder firmware, Niagara Video only guarantees compatibility with the GoStream
B264 series encoders in this mode.
The configuration parameters are as follows:
RTMP Protocol: This is an informational field. The only supported variant is
rtmp://.
RTMP Port Selection: If Use Default is selected, the decoder will listen on the default
RTMP Port (TCP Port 1935). If a custom, non-standard port is desired, select Specific
Port, and a new field will appear for the TCP port.
36
Port: This field is only displayed if RTMP Port Selection is set to Specific Port.
Configure a non-standard TCP port here.
RTMP App: any arbitrary name can be used here. Configure the exact same name in the
encoder.
RTMP Stream: this field is fixed at livestream. Configure this name in the encoder.
RTSP Client
In RTSP Client mode, the decoder will connect to an RTSP server (specified by an rtsp://
URL), request a stream, and play the stream. This mode is intended primary to support devices
such as IP Cameras. The configuration parameters are as follows:
The parameters are:
RTSP URL: Enter the full RTSP URL to access the RTSP server. Please consult the
RTSP server vendor to find out what to enter here. A comprehensive list of URLs from
the various IP Camera manufacturers can be found in this link.
TCP Transport: Standard RTSP uses a TCP connection to negotiate the streaming, and
RTP/UDP on a dynamically-allocated port for the video content. This mode of operation
is compatible with all RTSP devices, but it does not work well over the Internet nor can it
go across most firewalls. Many RTSP cameras support tunneling the video over the
control TCP connection, which works a lot better in complex networks, at the expense of
increased latency. If this box is checked, the BRD will request this tunnel mode. If this
mode works with your camera, it is preferred.
Authentication: Some RTSP devices can be configured to require username/password
authentication. Select Yes if this is the case. The following additional options are
displayed.
Username: enter the username expected by the RTSP device.
Password: enter the password expected by the RTSP device.
RTSP Reconnect: if this button is clicked, the BRD drops the RTSP connection and re-
creates it.
RTSP support in the BRD has the following limitations:
No audio support.
For video, only H.264 compression is supported.
No support for encrypted passwords.
37
Color Bars
No additional parameters are required for Color Bars. Use the Decoder Output Configuration
controls to specify the desired output, frame rate, and other video output parameters.
Decoder Program and Audio Selection
This section is only displayed if the Source parameter in Decoder Input Configuration is set to
either ASI Input or UDP/RTP Stream. It allows the following selections to be made:
If the stream being received by the decoder is a Multi-Program Transport Stream
(MPTS), the program to be decoded can be chosen here.
If the program being played by the decoder has multiple audio PIDs, the audio PIDs
being decoded can be selected here.
The parameters are:
Decoded Program, Available Programs: These two parameters work together, and are
used to select the program to be decoded in an MPTS. The program can be specified by
number in the Decoded Program field, or selected in the Available Programs drop-
down menu. If Program Auto-Select is checked, and a non-existing program number is
entered in the Decoded Program field, the decoder will ignore the setting and stay on the
current program.
Available Programs: This control is pre-populated with a drop-down list of the
programs available in the transport stream. If the program name can be determined, it
will be shown, with the program number in parenthesis. If not, the program is shown as
Program X, where X is the actual program number. In the example below, Program 1
has a name (NBC), so it shown as “(1) NBC”, and Program 2 does not have a name, so it
is shown as Program 2.
38
Program Auto-Select: If checked, if the decoder does not find the configured program,
it will automatically play the first program in the MPTS. Otherwise, it will not play any
programs
5
.
Audio 1 Service, Audio 2 Service: The BRD has two independent audio decoders.
These controls allow the selection of the audio service for each of the audio decoders.
The selection is a drop-down menu with the audio PID values. If a language descriptor
can be found for the audio service, the language code is displayed here as well. It is also
possible to disable audio decoding altogether, by selecting the Disabled option. An
example with three audio services (English, Portuguese and French) is shown below.
Decoder Output Configuration
This set of controls configures the video outputs. The appearance of the controls depends on the
selection made on the Digital Output parameter:
The following parameter is always available:
Buffering Latency (ms): the buffering latency through the decoder can be configured
using this parameter. The range is from 0 to 700 milliseconds. It can be used to reduce
overall end-to-end latency depending on stream delivery conditions. Values below
200 milliseconds must be used with care. If this value is set too low for the network
and encoding conditions, the BRD will stop decoding audio. Increase the value in this
case.
Digital Output: Disabled
No additional parameters are displayed in this case. Both the SDI and the HDMI outputs will be
disabled, and video will be present only in the composite output. The composite output will
present either an NTSC or PAL signal depending on the program being decoded.
5
In the current firmware version, this control is not available and is always checked.
39
Digital Output: SDI
This selection enables the SDI output. The composite and HDMI outputs will be disabled. Note
that, in this mode, the decoder may output a garbled signal on the HDMI output. Do not
use the HDMI output when SDI is selected, even if there is a signal present.
The available parameters are:
Resolution: Select the SDI output resolution. The decoder can convert between formats
and frame rates, so this selection can be made independent of the decoded signal. The
available formats are:
SMPTE-334 Closed-Caption Type: The decoder supports Closed-Caption injection if
the incoming bitstream has captions. The options are:
o Off: no Closed-Captioning injection.
o EIA-608: Inject Closed-Captioning in EIA-608 format.
o EIA-708: Inject Closed-Captioning in EIA-708 format.
40
Audio 1 Embedded Group: Select the group to embed the first decoded audio service.
Groups 1 through 4 can be selected, or audio embedding can be disabled:
Audio 1 Embedded Channels: Select the channels to embed the first decoded audio.
The available choices are Channels 1-2 or Channels 3-4.
Audio 2 Embedded Group, Audio 2 Embedded Channels: These controls are similar
to the corresponding Audio 1 controls. They select the embedding of the second decoded
audio pair.
Format: This selects the output format. It is only relevant if the BRD is decoding a
Standard Definition (SD) signal and up-converting it to HD. Setting format to 4x3 will
produce a pillarbox image (a 4x3 image with black bands on both sides). Setting format
to 16x9 will stretch the image to full screen – this is recommended if the SD signal is
anamorphic.
Enable Genlock: If this box is checked, the SDI output can be genlocked to a reference
signal. The following controls become available:
GOSTREAM BRD card
GOSTREAM BRD stand-alone
Genlock Source: This control is displayed only for the openGear version of the decoder.
The openGear chassis has two reference inputs, marked Ref 1 and Ref 2. The
GOSTREAM BRD card will accept the genlock reference signal from either input.
41
DFR-8321 Frames OG3-FR Frames
Reference Inputs
Genlock Line Offset: By default, the BRD will align the beginning of the video frames
between the genlock reference and the SDI output. This control allows the offset to be
changed by an integral number of lines. The available range for this parameter depends
on the SDI output selection, as follows:
Genlock Sample Offset: By default, the BRD will align the beginning of the video
frames between the genlock reference and the SDI output. This control allows the offset
to be changed by an integral number of samples (pixels). The available range for this
parameter depends on the SDI output selection, as follows:

Digital Output: HDMI
This setting enables the HDMI output. The SDI output will be disabled. Depending on the
HDMI resolution settings, an SD version of the signal may be present in the composite output.
Resolution: select the desired HDMI output resolution. You can choose a specific
resolution, or select Auto. In Auto mode, the decoder will communicate with the HDMI
monitor, determine its optimum resolution, and provide a signal of that resolution. Note
the following for Auto mode:
o If the monitor requests a non-standard resolution, the decoder will comply, but the
composite signal will be turned off. If a composite signal is required, select one
of the standard modes.
o If the monitor does not complete the negotiation with the decoder, no video will
be displayed. Select a standard resolution in this case.
Format: This selects the output format. It is only relevant if the BRD is decoding a
Standard Definition (SD) signal and up-converting it to HD. Setting format to 4x3 will
produce a pillarbox image (a 4x3 image with black bands on both sides). Setting format
to 16x9 will stretch the image to full screen – this is recommended if the SD signal is
anamorphic.
Decoder Analog Audio Configuration
This area configures the analog audio stereo output. It includes the following controls:
Analog Audio Source: Selects between the first and the second decoded audio services
for the analog output.
Mute Left, Mute Right: these controls will mute the corresponding audio analog output.
43
Gain Right, Gain Left: these controls can provide independent audio gain or
attenuation for the left/right channels. The range for these controls is from -12 dB to
+12 dB, in steps of 0.5 dB.
Output Level: This control is only displayed if the decoder is fitted with balanced audio
outputs. Select between SMPTE and EBU output levels.
Decoder Apply/Cancel Buttons
When the Apply button is clicked, the decoder configuration takes effect. All changes cause
interruption to the video stream, except for changes related to audio – namely any changes in the
Analog Audio Configuration or the Audio Service Selection.
If there are no errors, the Decoder configuration area closes. If any errors are detected, an error
message is displayed by the Apply button. The possible error messages are:
Error: no available IP License: the Source parameter in the Decoder Input
Configuration is set to one of the IP protocols, and the unit does not have the IP License
(check the Admin License Keys Tab). Contact Niagara Video if you need to acquire this
license.
Error: no available Dolby License: the incoming stream has Dolby audio, and the unit
does not have the Dolby decoding license (check the Admin License Keys Tab). If the
program has other audio services, select an alternate audio PID in the Decoder Program
and Audio Selection area. Contact Niagara Video if you need to acquire this license.
Error: no available Genlock License: the Enable Genlock parameter in the Decoder
Output Configuration is enabled, and the unit does not have the Genlock License (check
the Admin License Keys Tab). Contact Niagara Video if you need to acquire this license.
If the Cancel button is clicked, all changes are discarded, and the parameters return to their
original values.
Decoder Program Info Tab
The information available in the Program Info tab depends on the setting of the Source
parameter in the Decoder Input Configuration.
Program Info Tab for ASI Input and UDP/RTP Stream
For ASI Inputs and UDP/RTP Streams, the Program Info tab displays the information about the
transport stream being received:
44
Header Information: The top header indicates the Transport Stream ID (TSID). For
each program, an individual header is provided, showing the Program Number and the
PMT PID.
Program Name: If available, the Program Name is displayed. If the transport stream
contains a Service Description Table (SDT), the Service Name is displayed here. If the
transport stream contains a Virtual Channel Table (VCT – used in terrestrial ATSC
broadcasts), this field will show the major and minor channel numbers, and the short
channel name (as depicted above).
Elements: For each program, a list of elements is provided. The list contains the
Element PID, the element type (Audio/Video/other), and the type of compression if
appropriate. For audio streams, if a language code is present, it is displayed here as well.
Transport Stream ID
PMT PID
Element PIDs
Program Info Tab for HLS Stream
For HLS Streams, the Program Info Tab shows the available profiles and their bit rates. It also
shows which profile the decoder is currently downloading.
The controls available in this tab are:
Profile Switch: If this is set to Automatic, the decoder will select the highest bit rate
profile supported by its Internet connection. If this is set to Manual, the Load buttons in
the Select column will become available, and a specific profile can be selected.
45
Load: these buttons can be used to manually select one of the available profiles. If a
button is pressed, the State entry next to it will indicate Requested until the decoder
starts downloading that profile.
The table will also show the bit rate for each profile (as informed by the HLS server) and will
indicate which profile is currently being downloaded – marked as Selected in the State column.
Program Info Tab for RTMP Client and Server
For RTMP Streams, the Program Info Tab shows the RTMP Metadata, if it has been provided by
the client or the server.

Program Info Tab for Color Bars
No additional information is presented in the Program Info Tab when the decoder is in Color
Bars mode:
Decoder Statistics Tab
The Decoder Statistics Tab is divided into three bottom tabs:
The Status tab displays the current decoding status and information.
47
The Network tab displays network statistics. It changes according to the decoder source
selection.
The Configuration tab is a mirror of the Configuration Tab and displays the current
decoder configuration.
Status Tab
The Status Tab provides basic information about the state of the decoding (whether it is decoding
or not) and information about the stream being decoded, if available. If the Enable Genlock
control in the Digital Output: SDI section of the decoder configuration is checked, additional
fields related to the genlock function are displayed.
The Status Tab includes the following information:
Decoder State: if this indicator is green, the content is being decoded normally.
Otherwise, it will be red and the state of the decoder will be displayed.
Program Information: this section contains general program information: program
number, name (if available), and the PMT and PCR PIDs.
Video Information: this section contains information about the video stream: PID,
CODEC (H.264 or MPEG-2), resolution, and whether it is progressive or interlaced.
Audio Information: if audio decoding is enabled, this section contains information about
the stream being decoded. There are two audio information sections, one for each audio
decoder. If the audio decoder is enabled, it contains the PID, CODEC, and language
code (if present in the stream).
48
If the Enable Genlock control in the Digital Output: SDI section of the decoder configuration is
checked, two additional information items are included in the Status Tab:
Genlock Status: this field can show the following values:
o OK: The genlock function is operating normally, and the output is genlocked
to the reference.
o Incompatible Reference: The BRD has detected a valid genlock signal, but
the decoder output is incompatible with this genlock signal. Please consult the
49
genlock compatibility matrix below to confirm the supported combinations. The
SDI output is NOT genlocked to this signal and is free-running.
o Unlocked: The BRD is not detecting any genlock signal. The SDI output is
free-running.
Genlock Signal: this field indicates the resolution and frame rate of the detected genlock
signal.
Not all combinations of SDI output standard and genlock signal are supported. The matrix
below indicates what combinations are legal.
Genlock Compatibility Matrix
Network Tab
The Network Tab contains protocol-specific statistics and changes according to the decoder
source selection.

Received Rate (b/s): indicates the measured rate in bits/second at the input of the
decoder. This does not include FEC bit rate or UDP/IP overhead – it is the transport
stream rate.
Protocol: indicates the detected protocol, either UDP or RTP.
Stream Source IP Address: indicates the current IP address from which the stream is
being received.
SMPTE 2022 FEC: Indicates the detected FEC mode, as follows:
o None: SMPTE 2022 FEC transmission is not being detected by the BRD.
o Column Only: The BRD is detecting SMPTE 2022 FEC in Column Only mode.
o Row and Column: The BRD is detecting SMPTE 2022 FEC in Row and Column
mode.
o Not Licensed: The SMPTE 2022 functionality is not licensed in this unit (see the
Admin License Keys Tab). If SMPTE 2022 FEC is present, it is being ignored by
the BRD.
Columns: If SMPTE 2022 FEC is being received, this indicates the number of columns
detected.
Rows: If SMPTE 2022 FEC is being received, this indicates the number of rows detected.
Received Packets: This indicates the number of packets received since the last time the
statistics were reset. This count does not include the FEC packets, if any.
Lost Packets: This indicates the total number of lost packets since the last time the
statistics were reset. Note that the BRD can only detect lost packets if the incoming
protocol is RTP. It is not possible to detect lost packets with UDP as it lacks a sequence
number.
Recovered Packets: This indicates the total number of packets recovered with SMPTE
2022 FEC since the last time the statistics were reset.
Unrecovered Packets: This indicates the total number of lost packets that could not be
recovered with SMPTE 2022 FEC (either because of excessive loss or because SMPTE
2022 is not present).
51
The counts for Received Packets, Lost Packets, Recovered Packets and Unrecovered Packets can
be reset at any time by clicking on the Reset Network Statistics button in the UDP/RTP Stream
area of the Decoder Input configuration, also reproduced below:
Network Tab for HLS Stream
The Network Tab statistics for the HLS Stream are show below:
Type: This field will contain the following values:
o Unknown: the stream type is unknown.
o VOD: the stream is VOD content. This means that it is finite, it has a well-
defined end. The BRD will stop playing the content at the end, use the Restart
HLS Playback button in the HLS Stream configuration area to play it again.
o Live Stream: the stream is live.
o Event: the stream is an event. This means that it is finite, it has a well-defined
end. The BRD will stop playing the content at the end, use the Restart HLS
Playback button in the HLS Stream configuration area to play it again.
Profiles: indicates the number of profiles advertised by the server. You can get more
information about the profiles in the Program Info Tab for HLS Stream.
Profile Rate: indicates the bit rate of the current profile being downloaded, as advertised
by the server.
Segments Loaded: indicates the number of segments downloaded from the server since
the connection was made.
Segment Duration (s): Indicates the segment duration, in seconds, advertised by the
server.
52
Network Tab for RTMP Client and Server
The Network Tab Statistics for the RTMP Client and Server modes is depicted below:
Received Rate (b/s): indicates the measured rate in bits/second at the input of the
decoder.
Stream Source IP Address: if there is an RTMP connection, it indicates the IP address
of the source. In RTMP Client mode, this is the IP address of the RTMP Server from
which the decoder is pulling the stream. In RTMP Server mode, this is the IP address of
the publishing client.
RTMP Connection: this shows the RTMP connection state, as follows:
o Connected: The decoder has established a connection with the RTMP server
or client and is transferring data.
o Not Connected: The decoder has not been able to connect to the RTMP server,
or there is no RTMP client connected to it. If the decoder is in RTMP client mode,
check the Admin Event Log Tab for possible reasons why it is unable to connect.
Network Tab for RTSP Client
The Network Tab Statistics for the RTSP Client is depicted below:
Received Rate (b/s): indicates the measured rate in bits/second at the input of the
decoder.
Stream Source IP Address: if there is an RTSP connection, it indicates the IP address of
the source.
RTSP Connection: this shows the RTSP connection state, as follows:
o Connected: The decoder has established a connection with the RTSP server
and is transferring data.
o Not Connected: The decoder has not been able to connect to the RTSP server.
53
Video Protocol: RTSP creates a separate connection to transfer the video bitstream. This
field contains a textual representation of the protocol name, obtained from the RTSP
server.
Video UDP Port: RTSP creates a separate connection to transfer the video bitstream, and
the UDP port used in this transfer is dynamically negotiated with the server. This field
reports the UDP port number being used. Note that if the protocol is RTP, two
consecutive ports are used. In the example above, port 59970 is being used for the video,
and port 59971 is being used for RTCP.
Video CODEC: This field contains a textual representation of the video CODEC, as
reported by the server. The BRD only supports H.264 in RTSP mode, but this field will
always be updated.
Video Frame Rate: This field contains the video frame rate, as reported by the RTSP
server.
Network Tab for Color Bars
No additional information is presented in the Network Tab when the decoder is in Color Bars
mode:
54
Configuration Tab
The Configuration Tab shows the current running configuration of the decoder. When the Apply
button is pressed, the changes made in the configuration area are reflected here. It follows the
same layout as the Decoder Configuration Tab. An example is shown below:
55
IP Outputs Tab
The BRD is capable of doing ASI to IP turnaround, if it equipped with the optional IP Output
license (see the Admin License Keys Tab). The output streams can be sent using UDP or RTP,
and, if the unit has the SMPTE 2022 FEC license, it can also transmit a FEC stream.
The IP Output function is independent of the decoder source selection and is always available.
For example, the decoder may be displaying a stream received from Ethernet, and at the same
time transmitting an ASI stream over IP.
The IP Output function of the BRD has the following capabilities:
Protocol support: UDP, RTP and SMPTE-2022 FEC (if licensed)
Full transport transmission
MPTS splitting into multiple SPTS streams
NULL-padding of SPTS streams
Support for up to 16 IP flows
Transmission always uses the streaming Ethernet port
IP Outputs Configuration Tab
The IP Outputs configuration tab is depicted below. It contains 16 pre-defined IP output streams,
managed as follows:
Stream 1 is always the full transport stream received from the ASI input.
Streams 2 to 16 are SPTS streams, automatically pre-populated with the programs present
in the ASI input, in the order they appear in the PAT.
The most common settings and statistics for each stream are shown in the table below. Note that
changes in the table take effect immediately. The columns are:
Program: This column shows the program number for the specific stream. The possible
values are:
o All: this will only be shown for Stream 1, to indicate that it is the full transport.
o 1 to 65535: these are program numbers, read from the PMT.
o None: this will be displayed for streams for which there are no available
programs. These streams can be configured, but will only actually transmit if the
transport changes and more programs appear.
Enable: Checking this box enables transmission of a particular stream. This operation
will fail if the BRD does not have an IP Output license.
Destination Address: Enter the desired destination IP address for the stream. Both
multicast and unicast are supported.
UDP Port: Enter the desired UDP port for the stream.
RTP: If this box is checked, the RTP protocol is used. If not checked, the UDP protocol
is used. Note that RTP requires that the UDP port be an even number. Checking this box
will change the UDP port to the next even number if it is an odd number.
56
NULL Pad: If this box is checked, the stream is made CBR by padding it with NULL
packets. The padding rate can be controlled by using the Advanced Edit button. This
function is not available for Stream 1 as it is already padded from the ASI source.
Input Rate: This field reports the instantaneous measured input rate for the stream.
Peak Rate: If the stream is enabled, this field reports the peak rate observed in the stream
since it was enabled.
Output Rate: This field reports the output rate of the stream. If NULL padding is
disabled, it will match the input rate. If NULL padding is enabled, it will correspond to
the padding rate.
Advanced Edit: When the Edit button is clicked, the Advanced Edit area opens at the
bottom of the table. This allows for detailed configuration of the port, including the
NULL padding parameters, IP parameters, and FEC parameters. A more detailed
description of the edit area is provided below.
When the Edit button is clicked for a stream, the following message appears at the top of the
table:
57
At the bottom of the table, the Advanced Configuration area opens:
Changes made in this configuration area only take effect when the Apply button is clicked. If
the Cancel button is clicked, the changes are discarded. The configuration area closes when
either button is clicked.
The Enable, Destination Address, UDP Port, RTP and NULL Padding fields correspond to
the fields in the table, described above. The following additional parameters are available:
TOS: This parameter allows the configuration of the Type-Of-Service (TOS) byte in the
IP header (also known as the Differentiated Services – DS – field). Valid values are
between 0 and 255. Configuring this is only useful if the downstream router is
configured to honor the field.
TTL: This parameter allows the configuration of the Time-To-Live (TTL) byte in the IP
header. Valid values are between 0 and 255. If not explicitly configured, it defaults to
128. This field controls how many hops the packet can traverse before it is dropped by a
router. The default value of 128 is suitable for virtually all applications.
If the RTP box is checked, the following additional control becomes available:
58
SMPTE 2022 FEC: Select the FEC mode, as follows:
o Disabled: No SMPTE 2022 FEC packets are transmitted.
o Column Only: The BRD will send a single FEC flow, corresponding to the
column protection data, using a UDP port number corresponding to the media
UDP port number plus 2.
o Row and Column: The BRD will send two FEC flows, the first corresponding to
the column protection data, and the second corresponding to the row protection
data. The row protection data will be sent using a UDP port number
corresponding to the media UDP port number plus 4. Note that not all receivers
support Row and Column mode; such receivers will only use the FEC Column
data and discard the FEC Row data.
If either Column Only or Row and Column are selected, the following additional
controls are displayed:
Columns: Number of columns in the FEC matrix. This variable must be between 1 and
20 if SMPTE 2022 FEC is set to Column Only, and between 4 and 20 if it is set to Row
and Column.
Rows: Number of rows in the FEC matrix. This variable must be between 4 and 20.
If the NULL Padding box is checked, the following additional control is displayed:
Auto Bit Rate: If this box is checked, the BRD will automatically determine the NULL
padding rate for the stream, based on the measured peak rate. The auto rate may change
over time if the stream peaks at higher rates. The current auto bit rate can be read in the
