Ref In LED: this LED is on if a valid reference signal is detected at the reference input.
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-software3 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.
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.
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.
Network Tab The Network Tab allows for configuration/monitoring of the streaming Ethernet port. Network Configuration Tab The Network Configuration Tab is used to set the individual parameters for the streaming Ethernet port. The following parameters can be configured: Alarm on Link Loss: If set to Yes, the card will raise an alarm if this Ethernet interface loses link. The Card State indicator in Dashboard™ and the front Status LED will both be red.
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.
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. IGMP Version: Reports the current setting for this parameter.
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.
Click here to configure 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.
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.
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.
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.
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.
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).
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).
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.
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.
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.
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.
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 programs5. 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.
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.
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.
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.
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.
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.
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.
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 RTSP Streams No additional information is presented for RTSP streams in the Program Info Tab: 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.
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, 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Output Rate column of the table. If this box is unchecked, the following additional control is displayed: Bit Rate: Enter the desired NULL padding bit rate, in bits/second. Note that if the stream data rate peaks over the configured value, data can be dropped, depending on the peak duration (the BRD will buffer the data for short periods of time, but the MPEG buffer models may be compromised).
Monitoring Tab The BRD is capable of doing basic stream monitoring, if it equipped with the optional Monitoring license (see the Admin License Keys Tab). It will monitor the stream being decoded. This function is only available for transport streams received from ASI or UDP/RTP (with or without SMPTE-2022 FEC). The Monitoring function of the BRD has the following features: Capable of displaying instantaneous bit rate for up to 32 PIDs in the incoming transport stream.
The following controls are available: PID Display: selects Hexadecimal or Decimal display for the PID values. Hexadecimal PID displays are prefixed with “0x”. Reset PID Statistics: if this button is clicked, the CC Error counts are reset to zero. Also, the list of detected PIDs is also reset, and PIDs are re-discovered from the stream. The PID monitoring results are displayed in a table with the following columns: PID: discovered PID value. Only PIDs present in the stream are displayed.
This table allows up to 8 alarms to be configured, as follows: PID: Enter the desired PID value to be monitored. This field accepts both decimal and hexadecimal entries. For example, the PID value 256 can be entered either as 256 or as 0x100. Trigger (s): Enter the desired timeout for the PID, in seconds. If the PID disappears for a period of time greater than what is configured in this field, the alarm is raised. Enable: Check this box to enable the alarm.
Admin Tab The Admin tab contains a number of general administrative functions, each on its own tab. The general layout is shown below: The Admin tabs are: General: Manages a number of general card parameters; provides an SNMP MIB download. Firmware: Manages firmware images. Config Files: The BRD has the ability to store multiple configurations, and it has a number of pre-set configurations as well. These are managed in this tab.
Admin General Tab The Admin General Tab includes the following parameters: Card Name: This field defaults to GoStream BRD but can be set to any descriptive name. The name provided here will also appear in the Dashboard™ Tree View. SNMP Traps: This allows SNMP traps to be enabled or disabled6. Note that this setting does not take effect immediately – it will become active the next time the card is rebooted. MIB File Download: The BRD provides an up-to-date copy of its MIBs.
managed – the unit will never replace a DSP image required by any of the loaded firmware images. BRD firmware and DSP images are updated in the same fashion as with any standard openGear™ card. Once you obtained the upgrade image from Niagara Video, place it anywhere in your computer and click on the Upload button, as shown below. A dialog box allows you to select the upgrade file. Note that you can simultaneously upgrade all of your BRD cards and stand-alone units over multiple chassis if you wish.
Factory Image, Image 1, and Image 2: These contain version and release date information for the corresponding firmware images. If no image is present, this field will indicate No Image. This field also shows the required DSP image for each of the firmware images. Upload Location: This field contains the location where the image upload will go. The BRD automatically chooses a location that will not overwrite the currently running image.
User-Saved Configurations The fields in the user-saved configuration are: Status: This indicates whether there is a saved configuration on that particular slot. It will contain the words Saved or Empty. Name: This is an optional name for the configuration. It is not required but highly advisable. The name can be edited at any time (even when there is no saved configuration). Config Load Button: If you click on this button, the corresponding configuration is loaded in the BRD card.
3. Select the Data Safe tab in the configuration area. 4. Uncheck the Disable checkbox corresponding to the card you wish to restore the configuration. This step is depicted below. 5. On the Dashboard Tree View, right-click on the card, and select Restore Configuration. Follow the prompts and navigate to the file you wish to restore.
This process is discussed in further detail in the Dashboard User Manual, chapter 5, section Restoring Configurations to Devices. Pre-defined Templates The BRD offers 5 pre-defined configuration templates, as indicated below. To load a template, just click on the Load button next to it. The pre-defined templates are; Decode ASI to HDMI/Composite: This template assumes a signal present in the ASI Input, decode it, and simultaneously outputs it to the HDMI and composite ports.
The button does not affect the following areas: The settings in the Network tab are not changed. The settings in the Admin General tab are not changed. Saved configurations are not modified in any way. Dashboard will take a few seconds to reload (longer if you are accessing over a wide-area network), but the actual configuration in the BRD is virtually instantaneous. The Status Message Area will indicate the result of the operation.
IP Output: This field indicates whether the unit is licensed for ASI to IP Output. If it has the SMPTE 2022 FEC license, it will also be able to generate FEC on the output streams. Monitoring: This field indicates whether or not the unit is licensed for stream monitoring. If you want to request a license key from Niagara Video, you will need to provide the card serial number. It can be found in the Product Tab and in the Admin License Key Tab as well.
Date: The calendar date in which the event occurred. Time: The time at which the event occurred. Severity: The severity of the event. The BRD defines three severity levels: o Error: These are events that affect the operation of the device. For example, an ASI Input losing lock. An error will impact service until addressed. o Warning: These are events that may produce visible glitches, but they do not have a continuous service impact. o Info: These are informational events.
If your frame controller has access to the Internet, you can point it to one of the public NTP servers for your region. You can find more details on this link: http://psp2.ntp.org/bin/view/Servers/WebHome The full Admin Event Log tab is displayed below: The fields are: Log Download: The user interface only displays the last 10 events of each type. If you would like to see the whole event log, it can be downloaded to your computer by clicking on the Save button.
Current Time: This field indicates the BRD view of what the current date and time is. If your frame is not NTP-synchronized, this is useful to figure out “how long ago did this event happen”. Clear Log Display: If you click on this button, it clears all log views. This is useful to quickly identify any new events after the unit has been set up. Note that this action does not clear the logs stored in non-volatile memory. The BRD will store up to about 400 kBytes of logs in non-volatile memory.

Control Tab The Control Tab is used to configure the management Ethernet ports in the GOSTREAM BRD stand-alone. This includes both the IP information, as well as the SNMP parameters. The Control Tab is only displayed for the GOSTREAM BRD stand-alone. The management port supports operation at 10, 100 and 1000 Mb/s, both half-duplex and fullduplex, with auto-negotiation and auto-crossover detection. The Control Tab has two bottom tabs: Control Port is used to configure the IP parameters of the control port.
o DHCP: This option selects control port IP address configuration by DHCP. If this option is selected, the IP Address, Subnet Mask and Default Gateway fields are not shown. IP Address: This field is only shown if IP Configuration is set to Static IP. Enter the desired control port IP address. Subnet Mask: This field is only shown if IP Configuration is set to Static IP. Enter the desired control port subnet mask. Default Gateway: This field is only shown if IP Configuration is set to Static IP.
SNMP Configuration Tab The GOSTREAM BRD stand-alone includes a built-in SNMP agent with support for SNMP V1 and V2C. It will respond to SNMP transactions only on the control port, for security reasons. This tab includes the parameters for the SNMP configuration. Changes to these parameters take effect immediately.
The SNMP parameters are as follows: Read Community: this is the SNMP Read-Only community string. Write Community: this is the SNMP Read-Write community string. System Contact: this configures the value for the MIB-II System variable System Contact. Whatever value entered here is returned for SNMP queries to that variable. System Location: this configures the value for the MIB-II System variable System Location. Whatever value entered here is returned for SNMP queries to that variable.
