Introduction
The 9223-SA is an advanced openGear™ H.264 SD/HD dual-channel encoder, with the following features:
• Video Inputs: support for composite, SD-SDI, HD-SDI, and 3G-SDI.
• Audio Inputs: support for unbalanced analog audio, and SDI embedded digital audio.
• Outputs: 2 ASI ports and 2 Ethernet ports, supporting 100 Mb/s and 1 Gb/s operation.
• Replication: each encoded stream can be replicated on both ASI ports and 4 times on
each Ethernet port.
• Support for UDP/RTP on Ethernet.
• Support for SMPTE 2022 FEC on Ethernet.
• Closed-Captioning support (both EIA-608 and EIA-708 captions).
• AFD extraction and insertion support.
• Audio Encoding support: MPEG-1 Layer II and AAC-LC.
• Support for pre-compressed Dolby AC-3 pass-through embedded in SDI inputs.
• Support for secondary audio.
• Muxing support: each output can be configured to carry either encoder as a Single
Program Transport Stream (SPTS), or both encoders as a Multi Program Transport Stream (MPTS).
Product Overview
The 9223-SA supports up to two H.264 SD/HD encoders. The encoded transport stream can be routed and replicated to Ethernet and ASI outputs. Both SPTS and MPTS outputs are supported. The 9223-SA provides a compact form-factor standalone unit for distribution MPEG-4 encoding. Utilizing the openGear® open-architecture control/monitoring platform, the 9223-SA can be remotely controlled and monitored with the free, easy-to-use DashBoard™ setup and control operator interface.
The following inputs are available:
• Software-configurable Composite or SDI video inputs
• SDI video inputs support SD-SDI, HD-SDI and 3G-SDI
• Analog unbalanced audio stereo inputs
• SDI embedded audio support
• Two internal test packet generators (which can be used to generate ASI or IP test
streams)
The following outputs are available:
• Two ASI outputs
• Two Ethernet outputs, supporting full-duplex 100 Mb/s and 1 Gb/s operation
Basically, configuring the 9223-SA includes the following steps:
Step 1: Setup the 9223-SA to connect to remote control network using DashBoard. Step 2: Configure the encoders. Step 3: Configure the outputs (ASI or IP). Step 4: Make connections between inputs and outputs.
The connections between inputs and outputs can be made as part of the input or output configuration steps. The 9223-SA supports many-to-many connections.
The overall architecture is depicted below.

For the remainder of this manual, the term port for a physical input/output port (such as ASI or Ethernet), and stream for a transport stream present in the port. ASI ports support only one stream, while Ethernet ports support multiple streams.
Connecting 9223-SA To DashBoard Network Remote Control
Note: The 9223-SA is functional with all DashBoard versions, however GUI display response is optimized using version 3.0.0. Current DashBoard versions 4.0.0 and 4.1.0 may result in GUI pages taking more time to update.
DashBoard™ allows openGear® frames and their cards to be remote-controlled using a PC or Mac via a standard Ethernet connection. The DashBoard™ software can be downloaded from the Cobalt Digital Inc. website: www.cobaltdigital.com (enter “DashBoard” in the search window). When connected to your network, the 9223-SA appears in DashBoard just like any other device (similar to a frame).
1. Install the DashBoard software as described above. DashBoard is available for Windows,
Linux, and Mac OSX.
2. By default, the 9223-SA is configured with a factory IP address of 192.168.2.00 and a
subnet mask of 255.255.255.0. In order to perform the initial configuration, you will need to configure the PC/Mac running DashBoard for an IP address in the same network. We suggest you use 192.168.2.0. Once you gain access to the 9223-SA, you can reconfigure its IP address to whatever value you require, or configure it to run DHCP.
3. Connect the PC/Mac running DashBoard and the 9223-SA to the same network. For
simplicity, even running an Ethernet cable between the two devices will work. The 9223­SA has auto-crossover capabilities, so any Ethernet cable will work. Connect the cable to either one of the Control/Monitor ports in the 9223-SA, as illustrated below:
4. The DashBoard application should automatically find the 9223-SA and display it in the
tree view on the left. If the 9223-SA is not automatically found, click on the re-query button at the top of the DashBoard tree view, as shown below:
When the 9223-SA is found by DashBoard, it is identified as Standalone Encoder:
5. In the unlikely case that the 9223-SA is not automatically found by DashBoard, you can
force a manual connection. Select File Æ New Æ TCP/IP openGear Frame, enter the IP address of the 9223-SA, and click on Finish:
6. When the 9223-SA is available on DashBoard, open its user interface (by double-clicking
on Standalone Encoder to open it, and then on the device in slot 0). Go to the Control tab on the right; you can now configure the IP address of the 9223-SA as desired. You can also rename the device if you wish.
7. The two control ports in the 9223-SA are intended for redundancy. You can connect
either one of them (or both) to your control network. The 9223-SA will use whatever port is connected to respond to control operations.

Rear Panel Controls, Indicators, and Connectors
The 9223-SA rear panel is depicted below. It includes two software-configurable Composite/SDI video inputs on standard BNC connectors, two ASI output ports on standard BNC connectors, four unbalanced analog audio inputs on standard RCA connectors, and two 100/1000 Mb/s Ethernet ports on standard RJ-45 connectors.
The VID IN 1 / VID IN 2, ASI OUT 1 / ASI OUT 2, and ENET 1 / ENET 2 ports are equipped with LEDs that mirror the front-panel status respectively described in Front Panel Indicators for these ports.
Note: Unless specified otherwise, “Ethernet” settings, connections, and controls in the remainder of this manual refer to the transport (video stream) Ethernet interfaces carried over the ENET 1 and/or ENET 2 transport ports. The Control/Monitor ports are typically used only for unit network remote control (such as DashBoard).
9223-SA Operation and Management
The 9223-SA is configured using the free DashBoard™ application, which is available for Windows, Apple OS X, and Linux.
The 9223-SA user interface is depicted below. As with any openGear™ device, 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 of the unit. Note that the Card State (device state) alarm indicator is also reflected in the green/red STAT LED on the front panel. The STAT LED will be green when Card State is green or yellow, and will be red when Card State is red.
The following tabs are available:
• Product: this tab provides general information for the unit, 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
transport Ethernet ports. The statistics side of the panel includes some additional
information such as link state.
• Encoder 1, Encoder 2: these tabs are used to configure the two encoder channels.
• ASI Outputs: this tab is used to configure/monitor the ASI ports.
• IP Outputs: this tab is used to configure/monitor the IP Output ports. The configuration
panel provides the facilities to create, manage and delete ports; the statistics panel includes transmission status information.
• Connections: this tab is used to configure/monitor connections. The configuration panel
provides facilities to create, edit and delete connections; the statistics panel provides a table where the status of all the connections in the unit can be inspected at a glance.
• Admin: this tab is used for general administrative functions, such as firmware upgrades,
licensing, logs, and configuration management. The Test Packet Generator configuration is also found under this tab.
Product Tab
The Product Tab contains basic information about the 9223-SA.
The following information is available:
• Build Date: Date the firmware image was built.
• Supplier: Cobalt Digital Inc.
• Product: 9223-SA.
• Software revision: This indicates the firmware revision currently running. The format is
Major Version • Minor Version • Build Number.
• Serial Number: This is the serial number of this particular 9223-SA.
• Card Uptime: Indicates how long the unit has been running since it was last rebooted.
• Ambient Temperature: Temperature, in degrees Cesius, of the unit internal case
ambient temperature.
• Internal Temperature: Temperature, in degrees Cesius, adjacent to the unit PCB rear.
• MDP Core Temperature: Temperature, in degrees Cesius, of the core MediaStorm
processing element.
Network Tab
The Network Tab allows for configuration/monitoring of the two video transport Ethernet ports (Transport ENET 1 and Transport ENET 2).
Network Configuration Tab
The Network Configuration Tab is used to set the individual parameters for each of the Ethernet ports.
• The Interfaces tab is used to set the individual parameters for each of the streaming
Ethernet ports.
• The DNS tab is used to optionally configure DNS servers.
Configurat ion Tabs
Note: RTMP support requires that the device be capable of Domain Name Resolution (DNS support), as many CDNs use DNS-based load-balancing.
The following parameters can be configured:
• Alarm on Link Loss: If set to Yes, the unit will raise an alarm if this Ethernet interface
looses link. The Card State indicator in DashBoard™ and the front panel STAT LED will both be red. If set to No, the unit will still report loss of link in the Statistics page but no alarm will be raised. It is recommended that the alarm for ports that are in use be turned on; only turn it off if you do not plan to connect that port to a network.
• IP Address: Enter the desired IP address for this Ethernet port.
• Subnet Mask: Enter the desired subnet mask for this Ethernet port.
• Default Gateway: Enter the desired default gateway for this Ethernet port, or 0.0.0.0 if
no gateway is available.
• Interface Settings: If you make any changes to the IP Address, Subnet Mask and/or
Default Encoder 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 9223-SA will check the consistency of the data entered and will reject invalid combinations (i.e., combinations where the gateway is outside the interface subnet). Once the Apply button is pressed, a status message appears just below the Cancel button, as follows:
• Interface speed: Configures the speed of the interface. The 9223-SA Ethernet
interfaces only support two modes: 100 Mb/s Full-Duplex and 1 Gb/s Full-Duplex1.
o Auto-Negotiate: The Ethernet port will auto-negotiate the speed. 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.
Notes:
o If the 9223-SA streaming Ethernet interfaces are connected to a 10 Mb/s switch,
hub, or network feed, link will not be established and the port will not recognize the connection.
o If you select 100 Mb/s Full-Duplex or 1 Gb/s Full-Duplex and the
corresponding streaming Ethernet interface is connected to a switch, hub or network feed that does not support the selected speed, link will not be established and the port will not recognize the connection.
o If the interface speed is set to Auto-Negotiate, the streaming Ethernet port will
allow link to be established in 100 Mb/s Half-Duplex mode. However, this will be flagged as a warning.
Network Configuration DNS Tab
The DNS tab allows manual configuration of up to two DNS servers. They do not need to be in the same subnetwork as the streaming ports, as long as at least one default gateway is configured. DNS is only used in conjunction with the RTMP output functionality. If you are not using RTMP, there is no need to configure DNS servers.
1
Support for 10 Mb/s and Half-Duplex modes has been discontinued, as these are unsuitable for MPEG transport
over IP applications. Moreover, any modern switch supports at least 100 Mb/s Full-Duplex.
DNS server configuration takes effect immediately, as soon as the information is entered.
DNS Servers configured in the Control Tab have priority over servers configured here.
Network Statistics Tab
The Network Statistics Tab reports the current IP configuration of each transport Ethernet port, as well as their link state and running status.
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.
• Interface Speed: Reports the current setting for this parameter.
• Port 1/2 Link: This indicator has the following states:
o Link OK: The port has established link with the network connection. o Half-Duplex Link: The port is set to Auto-Negotiate, and it has achieved
100 Mb/s Half-Duplex link with the network connection. We do not consider Half­Duplex links suitable for video communication. The port will operate, but we recommend that this be addressed. If Alarm on Link Loss is set to Yes, the
Dashboard™ Card State will be yellow if there are no higher-priority alarms present.
No Link: The port does not currently have link. If Alarm on Link Loss is set to
o
Yes, the DashBoard™ Card State will be red and the front panel STAT LED 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.
• Port 1/2 Status: This indicator is the port overrun status. It has the following states:
o
OK: The port is operating normally.
o TX Overflow: In the current configuration, the IP outputs are attempting to
transmit more than the port capacity (i.e., the overall output data for this port exceeds the interface speed of 100 Mb/s or 1 Gb/s). The DashBoard™ Card State will be red and the STAT LED will also be red. In this case, reduce the output bit rate (either by reducing the encoder bit rates or by removing output ports). If this
indicator is red, data is being dropped.
• 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.
Encoder 1, Encoder 2 Tabs
The Encoder 1/Encoder 2 Tabs are used to configure/monitor the individual encoder channels. The parameters in these two tabs are identical.
Encoder Configuration Tab
The Encoder Configuration Tab is further divided into the following 3 tabs:
• Basic Tab: contains the more important configuration parameters, which all users are
likely to change.
• Advanced Tab: contains the advanced configuration parameters, which do not
necessarily need to be changed.
• Connections Tab: allows the creation of connections between this encoder and the ASI
and IP output ports.
Confi gurati on Tabs
In general, the encoder user interface will change as a function of the parameter selections made, to remove illegal parameter combinations.
Selections made in any of the encoder configuration screens do not take effect until the Apply button is pressed. If you wish to discard the changes made to the user interface, press the Cancel button. The Apply/Cancel buttons are present in all the tabs and will be grayed out until
changes are made. At any given point in time, the currently running encoder configuration can be inspected in the Encoder Statistics Tab, described later in this document.
Video Input Auto-Detection
The 9223 can be set to auto-detect the video input signal, and self-configure for the incoming resolution and frame rate. This feature allows the encoder to operate in situations where the video signal can change over time (for example, at the output of a video switch). The 9223 is even capable of automatically recognizing whether a signal is SDI or composite, and the video standard for composite signals.
The following points should be considered when using video input auto-detection:
• The available output scaling options are limited, since some options are specific to some
input resolutions.
• If the encoder is not licensed for a given configuration, it will stop encoding if the input
video signal switches to a value that requires this configuration. For example, an SD encoder configured to output the same resolution as the input will stop if the input signal switches to HD.
• If the encoder is configured with auto-detection and SDI embedded audio, it will fall
back to analog audio if it detects a composite video signal. If your input can switch between SDI and composite, either use analog audio for all signals, or make sure that the corresponding analog audio signal is present at the encoder unbalanced audio inputs when the video is a composite signal.
Multiple Audio Support
The 9223 can be licensed to offer up to two additional MPEG-1 Layer II audio channels, regardless of the number of installed encoders. These additional audio channels can be associated with the first or second encoder. Moreover, a dual-channel encoder can be configured as a single-channel encoder with combined audio. The following combinations are supported:
• Single Channel Encoders: support for 1, 2 or 3 audio stereo pairs, as follows: o First stereo pair:
MPEG-1 Layer II, AAC-LC or Dolby Passthrough supportValid inputs: analog unbalanced audio, SDI embedded (SDI signals only)
o Second stereo pair:
MPEG-1 Layer II support onlyValid inputs: second analog unbalanced audio, SDI embedded (SDI
signals only)
o Third stereo pair (only available for SDI inputs):
MPEG-1 Layer II support onlyValid input: SDI embedded
• Dual Channel encoders: support for 1 or 2 audio stereo pairs per encoder channel, as
follows:
o First stereo pair:
MPEG-1 Layer II, AAC-LC or Dolby Passthrough supportValid inputs: analog unbalanced audio, SDI embedded (SDI signals only)
o Second stereo pair (only available for SDI inputs):
MPEG-1 Layer II support onlyValid input: SDI embedded
• Dual Channel encoders can be configured to have one encoder channel with 3 audio
stereo pairs, and another encoder channel with 1 audio stereo pair, as follows:
o Encoder with 1 stereo pair:
MPEG-1 Layer II, AAC-LC or Dolby Passthrough supportValid inputs: analog unbalanced audio, SDI embedded (SDI signals only)
o Encoder with 3 stereo pairs:
First stereo pair:
• MPEG-1 Layer II, AAC-LC or Dolby Passthrough support
• Valid inputs: analog unbalanced audio, SDI embedded (SDI
signals only)

• Valid input: SDI embedded
• Dual Channel encoders with combined audio: support for up to 4 audio stereo pairs per
board, as follows:
o First stereo pair:
MPEG-1 Layer II, AAC-LC or Dolby Passthrough supportValid inputs: analog unbalanced audio, SDI embedded (SDI signals only)
o Second stereo pair:
MPEG-1 Layer II, AAC-LC or Dolby Passthrough supportValid inputs: second analog unbalanced audio, SDI embedded (SDI
signals only)
o Third stereo pair (only available for SDI inputs):

Encoder Basic Configuration Tab
The Encoder Basic Configuration Tab, shown below, is divided into three general areas:
• General Configuration: generic configuration parameters.
• Video Configuration: parameters related to video encoding.
• Audio Configuration: parameters related to audio encoding.
Note that the basic configuration tab may look different from what is depicted below, as the parameters may change (or appear/disappear in the GUI) based on the device’s configuration and the parameter choices made.
Basic Tab – General Configuration
• Name: All 9223-SA encoders and outputs can be assigned a user-defined name. This
name is used to identify the encoder later when making connections. Use any descriptive name suitable for your application, or accept the default.
• Encoder State: This control allows you to start/stop an encoder. This control needs to be
set to Running for normal operation.
• Input Connection: This control selects which of the two rear panel inputs is to be
connected to this encoder. The 9223-SA can run both encoders from the same input. The default is to run Encoder 1 from Video/Audio 1 and Encoder 2 from Video/Audio 2, but all combinations are allowed. Note that the parameters presented in the Video Configuration section may change if this selection changes (for example, if you switch the encoder from a Composite input to an SDI input).

Basic Tab – Video Configuration
The 9223 is capable of automatically identifying the video signal present in the selected input connection. The detected signal is reported in the Encoder Statistics Tab. Additionally, the encoder can also be set to auto-configure its input based on the detected signal:
• Video Input Settings: This parameter selects whether or not the encoder will auto-
configure based on the detected video input signal.
o Manual Selection: The input signal must be correctly selected using the Input
Resolution, Input Source, and Field/Frame Rate controls for the encoder to run.
If the input signal does not match the settings, the encoder will not run.
o Auto Detected: The encoder will auto-detect the input signal, and automatically
configure for it if it is a supported signal. The Input Resolution, Input Source, and Field/Frame Rate controls are not displayed.
The following table lists the supported input video signals:
Composite Signals SDI Signals

720×480i59.94 720×576i50 1280×720p50 1280×720p59.94 1280×720p60 1920×1080p23.98 1920×1080p24 1920×1080i50 1920×1080i59.94 1920×1080i60 1920×1080p50 1920×1080p59.94 1920×1080p60
If Video Input Settings is set to Manual Selection, the Input Resolution, Input Source and Field/Frame Rate parameters are displayed and must be set to match the incoming video signal.
• Input Resolution: Select the resolution of the input video signal. The following four
choices are available:
o SD: 720×480i (this will be presented as 720×576i if Field/Frame Rate is set to
PAL).
o HD: 1280×720p o HD: 1920×1080i o HD: 1920×1080p
• Input Source: Select the input source type. This control is available only if the Input
Resolution is set to SD. In this case, the options will be Composite or SD-SDI. If Input Resolution is set to any of the HD values, this control will not be selectable, and
will show the appropriate type of input (HD-SDI for 1280×720p and 1920×1080i, and 3G-SDI for 1920×1080p).
• Field/Frame Rate: Select to match your source. For all input resolutions, the supported
options always include 59.94 (for NTSC-based systems) and 50 (for PAL-based systems). Some resolutions have support for additional frame rates, as follows:
o If you select the 1920×1080i or 1280×720p resolutions, this field will also include
an option for a field rate of 60, used by same cameras:
o If you select the 1920×1080p resolution, this field will also include an option for a
frame rate of 23.98 (Film):
• Output Resolution: Select the desired output resolution. The values in this drop-down
list are a function of the Input Resolution and the Frame/Field Rate. Also, please note that some resolutions require additional licensing for the encoder. The following resolutions are offered:
o Same as the input (no scaling) o ¾ scaling from the input o Low resolutions: 480×270, 320×240, and 320×180, progressive, at half and
quarter frame rates (not available for 1080p inputs)
o HD inputs can be scaled (and re-interlaced if necessary) to SD resolution,
anamorphic (not available for 1080p inputs)
o 1080i, 720p and SD inputs can be converted to SD resolution, with progressive
frame rates (ideal for computer displays), as follows:
1080i59.94, 720p59.94, and 480i59.94 are converted to 720×480p29.971080i60 and 720p60 are converted to 720×480p301080i50 and 720p50 are converted to 720×576p25
The conversions from HD resolutions are done using anamorphic scaling.

o 1080i, 720p and SD
inputs can be scaled to 640×360, with progressive frame
rates, as follows:
1080i59.94 and 480i59.94 are converted to 640×360p29.97720p59.94 is converted to 640×360p59.941080i50 and 576i50 are converted to 640×360p25720p50 is converted to 640×360p50

By default, SD signals have a 4:3 aspect ratio, unless they are derived from an HD source with anamorphic scaling. The 640×360 resolution is intended for 16:9 content. Scaling SD to 640×360 should only be done if the SD signal is anamorphic to start with, otherwise the resulting encoded signal will have an incorrect aspect ratio.
o HD 1080i inputs can be scaled to ¼ resolution (960×540), with the same
incoming frame rate
o SD inputs can be horizontally cropped to 704 pixels or horizontally scaled to 640
pixels
If Video Input Settings is set to Auto Detected, the following options are offered in this parameter:
o Same as Input: the encoder will produce a signal that has the same resolution and
frame rate as the input (no scaling).
o Scale 3/4 Horizontal: the encoder will scale down the image horizontally by 3/4.
The frame rate will not be changed.
o Scale to 640×360p: the encoder will scale the input video to 640×360. The frame
rate will be the same as the input, but interlaced inputs will be de-interlaced (for example, 1920×1080i60 will yield 640×360p30). This resolution is not available for 1920×1080p inputs at any frame rates; the encoder will fall back to 3/4 horizontal scaling in this case.
o Scale to 480×270p, Scale to 320×240p, Scale to 320×180p: the encoder will
scale the input video to the selected resolutions. Interlaced inputs will be de­interlaced as described above. Progressive inputs will be encoded at half frame rate. This resolution is not available for 1920×1080p inputs at any frame rates; the encoder will fall back to 3/4 horizontal scaling in this case.
• Video Rate Mode: This controls whether the video elementary stream is CBR or VBR.
The video bit rate setting varies according to this selection, as shown below.
• Bit Rate Selection: This field is shown only if the encoder is set to CBR mode, and
allows the user to specify either the video bit rate, or the transport bit rate. The transport bit rate includes audio, video, tables, NULL packets, and various overheads. In some situations, such as for example, RF links of fixed capacity, it is more convenient to specify the transport rate (i.e., the final bit rate “in the wire”), and let the encoder compute the corresponding video bit rate to yield the desired transport rate. In other situations, such as IPTV deployments, it is more convenient to simply specify the video bit rate and let the encoder compute the final transport rate. Note that this control is not available in the OTT protocol modes. The controls displayed vary according to this selection:
• Video Bit Rate: This field is shown only if the encoder is set to CBR mode and the Bit
Rate Selection control is set to Video Bit Rate. It determines the video elementary stream bit rate, expressed in bits/second. Note that the bit rate resolution is 1000 bits/second.
• Transport Bit Rate: This field is shown only if the encoder is set to CBR mode and the
Bit Rate Selection control is set to Transport Bit Rate. It determines the overall transport stream bit rate, with a resolution of 1000 bits/sec; the encoder will calculate the appropriate video bit rate the yield the desired transport rate. Please note that all transport rates are achievable; in particular, the encoder may not be able to achieve very low transport rates if the audio bit rates are high. In these cases, the actual transport rate output by the encoder will be higher than the configured value. The actual transport rate is displayed in the Encoder Statistics Tab, after the Apply button has been pressed. At that point, the actual encoder video bit rate can be found in the Encoder Statistics Tab, under the Basic bottom tab.
• Peak Video Bit Rate, Average Video Bit Rate: These two fields are shown only if the
encoder is set to VBR mode, and determine the desired average and acceptable peak bit rates for the video elementary stream. The peak video bit rate must be between 2.0 and 2 times the average bit rate; the user interface will enforce these limits automatically (i.e., it will update either the average or peak to be consistent with the value being entered). For both of these parameters, the resolution is 1000 bits/sec.
Basic Tab – Audio Configuration
• Audio Source: This parameter selects the audio source. The options are Analog Audio,
directing the encoder will to use the analog right/left audio channels connected to the rear panel, and SDI Embedded Audio, directing the encoder to extract embedded audio from the SDI input. If the video Input Source (see Basic Tab – Video Configuration) is set to Composite, this parameter is grayed out and forced to Analog Audio. It will be selectable only if the video input source is one of the SDI variations. When SDI Embedded Audio is selected, additional configuration options become available, as shown below.
• Group, Channels: SDI embedded audio is typically divided into four groups (denoted by
Group 1 to Group 4); each group has four mono channels (2 stereo pairs), denoted by Channels 1-2 and 3-4. These controls allow the selection of the desired group and channel pair. In the large majority of the cases, the first stereo pair is in Group 1, Channels 1-2, the second stereo pair is in Group 1, Channels 3-4, and so on. The Group selection has one additional choice, labeled Custom DID. This allows the encoder to use a non-standard embedded audio DID (this quite uncommon). If Custom DID is selected, a new configuration option becomes available, where the DID can be entered:
• Group DID: Enter the desired Group DID, in hexadecimal. Note that the entry will be
immediately validated and rejected if invalid. As a reference, the table below contains the standard DIDs built into the system for Groups 1 to 4.
Group SD-SDI DID HD-SDI DID
Group 1 0x2FF 0x2E7 Group 2 0x1FD 0x1E6 Group 3 0x1FB 0x1E5 Group 4 0x2F9 0x2E4
• Language Code: This parameter represents the 3-letter ISO 639-2 language code for the
audio, to be placed in the audio language descriptor in the PMT.
• Audio Encoding: This parameter selects the audio encoding algorithm. The available
choices depend on the Audio Source selection. For Analog Audio, the choices are MPEG-1 Layer II and AAC-LC. For SDI Embedded Audio, the Dolby Passthrough option is offered in addition to the previous choices. Note that AAC-LC requires additional licensing. The two variants for this control are depicted below.
