Getting Started
Before you can use your Osprey Talon encoder, you first need to set up and configure
it. This chapter is dedicated to providing you with the details and step-by-step
instructions you need to make your installation as quick and easy as possible.
Here are three starting requirements:
AC power source (100 - 240 V)
IP connection and/or Internet connection on a dynamic host configuration protocol/domain name
server (DHCP/DNS) network.
A ‘configuration host’ system
A configuration host is a networked PC computer running a compatible HTML browser. The
browser on the host will be used to access the configuration web page on the Talon encoder.
There is also a small application called ‘Osprey BOSS’ that is used to locate and identify
Talon on the local network. BOSS works with PC and Linux. Once Talon has been identified
on the network any HTML browser can be used to configure your encoder.
The Osprey Talon encoder, an easy-to-use streaming device, allows you to:
Connect to a compatible browser on a dynamic host configuration protocol/domain name server
(DHCP/DNS) network.
Configure and connect your audio and video source to the Osprey Talon.
Select your output formats and streaming settings.
Enter your streaming server information.
Start streaming your media.
You can configure and use the Osprey Talon straight from the box for any streaming
activities. Use the web interface for setting options and controlling your Osprey Talon
from another networked computer.
This section addresses the high-level actions you must perform to physically connect
and set up your Osprey Talon video encoder.
Prerequisites
Before connecting the Osprey Talon encoder, ensure you comply with the following
prerequisites:
All packaged items are undamaged and in working order.
Your environment meets all starting requirements.

Using Talon for the First Time
All configuration of Talon is done via the internal web server. If you already know the IP
address of your Talon, simply type that address into a web browser on a computer that
has access to your network. You should proceed to the “Login” portion of this guide.
If you do not know the IP address of Talon, the Osprey BOSS utility is the best way to
determine the network location of Talon and connect with it. As an alternative to
installing Osprey BOSS, you can insert a Flash drive into the USB port on Talon. After a
minute, remove the Flash drive and insert it in an available PC. On the drive you will find
a file named “TalonIP.txt” that contains the IP address.
Osprey BOSS and DHCP
The easiest way to configure the address of Talon is to attach it to a network that
automatically assigns IP addresses via DHCP. Simply connect the network cable and
power up the Talon. DHCP will assign the IP address, Netmask, and Gateway. Then you
can use Osprey BOSS from a PC on the same local network to locate Talon and
connect to the web GUI. For best results, be certain your network is connected before
switching on your Talon.
Osprey BOSS Without DHCP
If your network does not support DHCP, it is still possible to use Osprey BOSS to discover
your Talon and assign a static IP address. As in the example above, connect Talon to
the network and power it on. Because there is no DHCP on the network, Talon will assign
the static IP address of ‘10.10.10.10’. From a PC on the same network, open Osprey
BOSS. BOSS will locate the Talon and display the IP address. It is most likely that this
address will not be compatible with your network. Use BOSS to assign a temporary
address to your Talon. Be certain that address is compatible with your network. Then
you can use BOSS to access the web GUI of your Talon. As soon as you log in on Talon,
navigate to the “System Control” tab and assign the correct static IP address in the
“Talon IP Setup” dialog. Be certain that you include a Default Gateway in the setup.
Talon will not be recognized unless it has a default gateway assigned. If your network is
small and does not require a default gateway, simply repeat the IP address in the
“Default Gateway” location. Do not leave it blank.
IMPORTANT NOTE: When Talon powers up it waits for a DHCP address. If it doesn’t
receive one immediately it will assign the 10.10.10.10 address. If Talon is set to wait for
DHCP and the power and network go down, it is possible that Talon will power up and

assign an address before the DHCP server can respond. If Talon powers up fully and the
encoder is set to auto-start the encoder could fail. If this happens, wait until the network
recovers and then power cycle your Talon to receive the DHCP address.
Osprey BOSS With an Invalid Static IP
You might find that you have configured Talon for a static IP on one network and then
moved it to a network where that address is invalid. Simply connect Talon to the current
network. Then start Osprey BOSS on a PC on that network. BOSS will identify the address
of the Talon even though it will not be able to connect with the web GUI. Similar to the
scenario above, use BOSS to change the invalid static IP to one that is valid on the
current network. Then access the web GUI and complete the updating of the address
on Talon.
Unknown IP Address Without Osprey BOSS
In this scenario, Talon is installed on a network and already has an IP address. You find
yourself without access to Osprey BOSS. With Talon powered up and attached to the
network, insert a thumb drive in the USB port of Talon. The thumb drive needs to be
formatted with either FAT or FAT32. After about minute remove the thumb drive and
insert it in another computer. On the drive, there will be a file called “TalonIP.txt” that
will contain the IP address and MAC address of your Talon. You can then use the IP
address to connect via a modern browser. Any time you insert a thumb drive into Talon
a “TalonIP.txt” file will be created.
IMPORTANT NOTE: Talon is only compatible with IPv4 addresses. Never connect an
Osprey Talon system to the Internet through a direct connection. We recommend
taking precautions against unwanted access such as installing systems behind a router
or firewall. The speed of the router or switch should match or exceed the speed of the
system’s network card. See your network administrator for recommendations.

4.0 Operating Mode
Talon has three operating modes. The current operating mode is indicated in the upper
right corner of the webpage along with the serial number and device name. The mode
can be changed from the menu just below the Device Management box on the
System Control tab.
1x3 MBR Mode
As the name suggests, MBR mode allows the user to select one of the available inputs
and then create three output streams. This is useful for Multiple Bit Rate streaming or for
streaming one input to several server locations at the same time. Users can create three
streams to a single RTMP server, or stream RTMP and UDP at the same time while saving
to file.
2X2 LC Mode
This mode is designed for Lecture Capture and similar uses. Users may select 1 SDI input
and 1 of either HDMI or Composite and stream each separately. This is useful for
streaming classroom situations where you need to stream a camera and an additional
input such as a scan converter or a laptop output for Lecture Capture. However, be
aware that LC mode is Progressive Only. This means that it does not apply any
DeInterlacing to the incoming signal. For this reason, it is not recommended to use
Composite (CVBS) in this mode.
1X1 3G Mode
In order to support streaming of full 3G-SDI video Talon must be set to this mode. 1X1 3G
mode allows for a full 1080p input to be encoded into a 1080p stream. This is also called
pass-through mode as it does not allow for any modification of the video other than
compression. The input resolution and frame rate will always match the output. Scaling
or deinterlacing is not supported in 1X1 3G mode.

Changing Operating Modes
On first startup, Talon will use 1x3 MBR mode. If you need to change modes, select the
desired mode from the dialog at the bottom of the page. Talon will reset itself into the
desired mode and reboot. Previous settings will not be retained.
5.0 Status
The Status page provides information about inputs and outputs. From this tab you can
get specific statistics about the incoming video, and outgoing audio and video
streams.

Stream Control Buttons
The five buttons in the Stream 1 Control box control the Stop and Start of the encoder
labeled Stream 1.
Stop/Start
Stop and Start buttons will start this particular stream only. Note that the button color
changes to indicate the status of the encoder.
Save
The Save button can be used to save the changes you make in the encoder
configuration below. Use Save if you are going to leave the configuration page without
starting the encoder. Once the encoder is started, all changes are automatically
saved.
Clone
Often a user wants to create second stream that is very similar to the first, with only
minor differences. You may use the ‘Clone” button to make a second stream
configuration that is exactly like the first. Then it is a simple matter to make the minor
change such as address in the second stream without having to recreate the whole
thing.
Delete
Delete completely removes the selected stream configuration.

Encoder Setup
By default the encoder setup dialog is presented in its simplified state with the
‘Advanced Settings’ button set to ‘Hide’. The user can take advantage of pre-set
Encode Profiles that configure the advanced settings for you. To see the full range of
available settings set the ‘Advanced Settings’ to ‘Show’.
Autostart
Autostart is available for each individual encoder. When Autostart is enabled that
encoder will automatically start as soon as Talon boots. This is useful for lights-out
encoding operations that need to come online automatically in the event of power
outage recovery. Other uses include single purpose encoders that will start on powerup without intervention.
Video Source
The choices in the pull-down menu vary depending upon the Operating Mode you
have selected.
In 1x3 MBR mode you may select from the three available input sources. Once
selected, the same input will be re-used for any additional streams.
In 2x2 LC mode the video source for Stream 1 must always be HD/SDI. The source
for Stream 2 can be either HDMI or Composite.
In 1x1 3G mode any input can be used. The encoded output will always be the
same as the input. This mode is required for 3G output.
NOTE: Composite is not recommended in 2x2 Mode.
NOTE: It is recommended in 2x2 Mode that the audio originate either from the SDI
source or the Analog source.

Encode Profiles
There are nine Encode Profiles available on Talon.
These range from ‘Low’ which creates a low
bitrate stream with a video resolution of 480x270,
to ‘HD 1080 60fps” which creates a robust 3G
stream. There are specialty profiles for Facebook®
and YouTube® that conform to the published
suggestions of those platforms. When an Encode
Profile is selected, Talon configures the advanced
settings. The Video Bitrate and Maximum Delay
can be adjusted without changing the profile.
Video Bitrate
Video Bitrate (vrate) is the desired encoded rate of
the outgoing video. Settings are expected in
Kilobits per second. For example, you may use
100000; 100k; 100K etc. You may also use 1m; 2m,
etc representing Megabits per second. 1G, etc is
not accepted.
NOTE: If a setting is out of bounds for the encoder
you will receive the message “status: !Error: Bad
vrate xK”. This only indicates that the setting is not
acceptable to Talon. It is possible to set a value
that is acceptable to Talon, but is not adequate to
support quality video.
Maximum Delay
This setting adjusts the amount of internal buffer the encoder is allowed to use. Larger
buffer gives the encoder more time to produce more accurate video. The default of
2000 is generally adequate for most streaming. A setting of 0 will result in blocky video. A
setting above 5000 does not usually provide a significant improvement.
In technical terms the Maximum Delay setting controls how much time is allowed for the
bitrate to reach the average set by the ‘Video Bitrate’. A longer buffer allows the
bitrate to rise and fall more with the complexity of the video. Some live encoding
applications do not tolerate large fluctuations in the bitrate. If you encounter such
problems set the Maximum Delay to the 100-300ms range. This will provide better results
for applications requiring a constant bit rate.

Advanced Settings
When an Encode Profile is selected, Encoder Setup displays a shortened menu. To view
all of the encoder’s settings select ‘Show’ from the Advanced Settings pull down.
If you are using an Encode Profile, many of the menus will be grayed out as the profile
overrides several of the settings. If you would like to start with an Encoder Profile, but
want to change some of the settings, first select the profile that best suits your need.
Then select ‘Custom’ from the bottom of the profile menu. If you have not already
opened the Advanced Settings, this will open them and all of the variables will be
available to you. Below are some of the settings available from the Custom menu.

resolution for the outgoing stream. To
make the stream the same resolution
as the input imply select “Follow
Input”. Otherwise select an outgoing
resolution from the list.
NOTE: Up-Scaling, (creating a stream
larger than the incoming resolution) is
not recommended as it usually results
in severely reduced quality.
Frame Rate
This is the frame rate of the encoded video. ‘Full’ will result in the same frame rate as the
incoming source. ‘1/2’ will be half the incoming frame rate.
Video Profile
Talon supports three h.264 encoding profiles; Baseline, Main and High. Profile selection
should be based on the target audience of the encoded video.
Baseline is the lowest level profile and is suitable for streaming to a broad
spectrum of internet connected devices including most older smart phones.
Main is the default setting. It is suitable for most web streaming including HD. It is
also good for most modern smart phones.
High is primarily used for broadcast, or for saving high-quality HD to file. It
supports up to 1080p/60 video.
GOP Size
GOP size refers to the distance between i-frames in a stream or file. Live streaming
generally uses shorter GOP sizes than saving to file. For live streaming a setting of 2 x
(frame rate) is a good starting point. If your encoded stream will be 30 fps, set the GOP
to 60 frames. Some server based transcoders prefer GOP up to 10 seconds.

Number of B Frames
B Frames provide encoding information to the i-frame. Talon supports from 0 to 2 B
Frames. When using Baseline profile use 0 B Frames. For most situations, a setting of 1
frame is best.
DeInterlacing
Most streaming video is destined for delivery to a computer or smartphone screen. Such
screens can only display progressive video. Most analog video and 1080i HD video are
delivered as Interlaced video. These sources must be de-interlaced before they can be
encoded for progressive delivery. Talon supports three settings.
OFF: No DeInterlacing will be applied.
DEINTERLACE: Standard DeInterlacing will be used.
DEINTERLACE HQ: This level is suitable for some save to file HD video.
NOTE: When encoding multiple streams, the same DEINTERLACE method is used across
all streams. Be certain to select a method that is applicable for all streams. Once a
stream has started the DEINTERLACE method cannot be changed on subsequent
streams until all streams are stopped.
Audio Enable
When set to “True” audio inputs are made available for embedding in the video
stream. Set this to “False” if this input will not be using audio.
Note that in 2x2 LC mode, only one input can supply audio at a time. Make certain the
audio is enabled on the input delivering audio and disabled on the rest or the video
may not start correctly.
IMPORTANT: If Audio Enable is set to “True” but there is not an audio signal present the
encoder will fail to start correctly. It may indicate streaming is occurring when in fact it is
not. You may see black video in your player but nothing else. To fix, restart the video
with “Audio Enable” set to “False”.

Audio Info
When “Audio Enable” is set to “True” the web
interface exposes the “Audio Info” fields.
Available options change to reflect the
Output Format as set in the Output Setup
area. Only the audio features used by the
particular input will appear.
Enable (all formats)
For Web streaming, only 1 pair of audio inputs
may be used at a time. Enable the input from
“Sub Channel 1” by selecting “yes”. When UDP
is selected, a total of 4 Sub Channels become
available.
Source (all formats)
Select from HD/SDI, HDMI, or Analog.
Codec (all formats)
For live streaming select from AAC-LC (low complexity) or AAC-HE (high efficiency). The
audio codecs labeled MPEG2 and MPEG1L2 are only used for MPEG2 TS streams.
Mode (all formats)
Select Stereo or Mono. Stereo is the default. When using Mono, you may select which of
the incoming pair contains the audio. Mono output will either use the left or right
channel, or in the case of a stereo input you may select to average the two channels.
Rtp Port (RTP only)
Select the audio port for the RTP stream. Default setting is 8900, but any port can be
selected. Common usage is from 4000 to 40000.
Pid (UDP only)
Identifies the UDP Process ID for this port.
Max PTS-PCR (UDP only)
Sets the maximum deviation for Presentation Time Stamps and Clock
Reference in UDP and MPTS delivery. Default is 250.
Format (UDP only)
Values are ADTS and LATS. Use the default ADTS for RTMP streaming.
Jumbo PES (UDP only)
Enables Jumbo PES and allows specification of number of AUs. Default is None.

Output Setup
The Output Setup dialog allows you to choose the Output Format and configure the
options necessary for each.
Output Format
This pull-down menu exposes the available streaming formats. The menu changes
depending on the Output Format selected.
RTMP
RTMP has become the most common delivery protocol for internet based video. RTMP
streaming requires a source, and encoder, and a streaming server. The resulting video is
then played in a browser window or via web based player. Many users us a Content
Delivery Network (CDN) do distribute their Live and On Demand video. The CDN then
also becomes the web server. CDN can also add value by recording and storing live
video for later delivery as Video on Demand (VOD).
XML file
Some CDN providers provide users with a .XML file the contains their encoding
parameters. You can download this configuration file to the host control computer and
select it from the “Choose File” dialog. At this time, only the RTMP address will be
populated. Other encoder settings such as Resolution and Bit Rate must be set
manually.

Product specifications and availability may change without notice <20161223
URL
This is where you manually insert the URL for the RTMP server. For complex addresses it is
preferred to copy and paste the address from the host control computer. You must add
the “RTMP://” in the address when you enter it.
Authentication
If your CDN uses a user name and password, then enable Authentication. A dialog box
will appear below to receive your username and password.
Frame Alignment
When creating multiple bit rate (MBR) streams it is preferred that all streams use the
same GOP length and the frames be sent at the same time. Frame Alignment “True” will
allow you to apply the same frame settings to all outbound streams.
NOTE: When creating multiple streams to the same source, be certain to enable “Frame
Alignment” on all streams.
UDP
UDP is a connectionless protocol often used in live video streaming. Most often it is used
to create a Multicast; a single stream that is shared across an entire network over a
Multicast IP address. This type of stream is accessible via set top boxes and other IP

devices. It is often used for digital signage. It can also be used for limited IP satellite
video.
Destination Address
Enter the Multicast address for your assigned video. It is only necessary to enter the IP
address, as the port number will be specified in the next menu.
Dest Port
This is the assigned port for your broadcast. The default is assigned in the 5000 range,
but any port can be used.
Video Settings
These are the video settings required by the network to deliver a stream to a particular
location. If this is the only stream you may use the defaults. Otherwise insert the values
given by your network administrator. Settings include Video PID, PCR PID and PMT PID.
TS Rate
In order to support the overhead of a Transport Stream the TS rate must be set greater
than the Video Bit Rate. As a rule, 125% of the Video Bit Rate is a good starting point.
Enable Save to File
When streaming with UDP it is possible to simultaneously save a copy to file using the
same encoding settings as your UDP stream. To save a copy of your broadcast as a .TS
file set this menu to “True”. When “True” is selected, the option appears to choose either
USB Flash Drive or Network Share as a location. For detailed information see the “Save
to File” instructions below. (p.34)

RTP
RTP is a delivery protocol similar to UDP. It is simple to configure as it only requires a
Destination Address and a Destination Port.
Destination Address
This address can be either Multicast or Unicast address depending upon your
requirements. You need only enter the destination IP address here.
Destination Port
Enter the destination port for your video stream. Default is 5004, but nearly all ports from
4000 to 40000 are available.
NOTE: Be certain to check the port on your Audio Configuration and set that port
accordingly as well.

About SDP files
Some RTP/RTSP connections may require a Session Description Protocol (SDP) file that is
placed on the media server to direct users to the stream. Talon does not support
creation or automatic injection of SDP files. Should your media server require such a file,
it can be created using notepad. The expected format for delivering video from Talon
is:

Save to File
Saving to file can be configured in two different places in Talon. If you select “Save to
File” under the “Output Format” menu one of your “Stream” tabs will be dedicated
exclusively to saving encoded output as a .TS file. After entering all of the proper
encoding settings select Save to File from the Output Format options in the Output
Setup dialog. This will create a stream from the selected input that will be saved in the
chosen location as a .ts file. Files can be saved either to a USB Flash Drive or to a shared
network location via the Network Share dialog. It is also possible to enable “Save to File”
as a simultaneous operation as part of a USB stream.
Destination: USB Flash Drive
Talon has no internal storage. In order to save a file via the USB port you must insert a
Flash drive or USB hard drive. Drives should be formatted in FAT32 or EXT2. The size of the
file you can save is determined by the file system on the drive. FAT32 can save a file up
to 4GB. EXT2 is capable of saving files up to 2TB. Obviously longer events will require
more storage. For example, a .ts file captured at 5Mb will require 2.2GB of storage per
hour. Larger files can be more easily accommodated by saving to a network share
rather than portable media.
Talon will not create folders or sub-folders on the Flash drive. In order to place a file in a
sub-folder be certain the folder exists before inserting the drive into Talon. In the “Path

and filename” dialog box enter the intended filename followed by ‘.ts.’ i.e.
“SavedFile.ts”. To save the file to a particular folder enter “foldername/filename.ts”.
NOTE: Talon does not determine if a device is plugged into the USB port. Be certain that
you have a storage device plugged into the USB before writing the file. Do not attempt
more than one Save to File operation to a flash drive at a time. Do not use a USB hub
with Talon.
Destination: Network Share
For larger files, or for saving to a Content Management Server, you can elect to save to
a Network Share. When this is selected, the dialog allows you to enter the Share Path
along with the necessary Username and Password. While there are practical limits to
the size of file you wish to handle, the technical file size on a network share is virtually
unlimited.

Locating Talon with Osprey BOSS
Talon is managed via a web based GUI that can be accessed over the network by
most web browsers. All you need to do is type the IP address of the Talon you wish to
access into the address bar of the browser. The simplest way to determine the IP
address is to power up Talon and connect it to the LAN. Once it is fully booted up and
on the network, Osprey BOSS will locate it and notify you of the IP address.
BOSS can be used if you do not know the exact IP address of your Talon systems. BOSS discovers Talon
devices on the network by broadcasting data packets to all IP addresses within your PC’s subnet (i.e. the
IP range that your PC is currently in). This means that the computer that is hosting BOSS should be on
the same IP subnet as Talon.
To locate all Talon devices on your subnet, click the “Locate Devices” button on the BOSS interface.
BOSS will populate with the Serial number, Device name, IP and MAC Address along with the Description
for all Talon encoders on this subnet.
To access a particular Talon, click on its Serial Number and you will be taken to the web GUI.
The “Always Listen” check box is only valid for Talon versions 1.6.0.212 and above. Checking will cause
BOSS to continually refresh Talon information without pressing “Locate Devices” again.

Clear Configuration
When this check box is selected, Talon will remove all encoder configurations from memory. You will not
be able to recover them.
Clear System
When this check box is selected, Talon will clear the encoder name and IP address from memory.
Selecting both “Clear Configuration” and “Clear System” will clear all settings and restore Talon to its
factory state.
Set a Temporary IP
Usually a Talon on the network receives its IP address via DHCP. It is possible to assign a static address.
Occasionally, when a static address is used an error can occur whereby the address doesn’t match the
correct specification for that network. When the address is wrong, it is not possible to access the Web
GUI of the Talon. BOSS is still able to locate and identify a Talon with an unreachable IP address, but will
be unable to connect to the Web GUI. For that reason, BOSS includes a utility to assign a temporary
address to allow access to the Web GUI.
To use this utility:
Click on the icon to the left of the Talon you need to change.
Select “Set IP” from the dialog box
In the “Set Device IP Address” dialog, enter valid IP information.
Press “Locate Devices” to refresh BOSS
Access Talon by clicking on the name of the Talon you want to reach
IMPORTANT NOTE: The IP address that BOSS assigns is only for accessing the web GUI. Upon
successfully reaching the GUI, use the Talon’s IP configuration to set it to DHCP or manually enter a valid
IP address. If you reboot Talon without first resetting its address in the web GUI you will return to the
situation where you started. You will once again have a Talon with an unreachable IP address.
Troubleshooting Note: BOSS will not locate Talon if:
Network Discovery is turned off on your Windows PC
Your Talon is not in the same network segment (VLAN/subnet) as your PC
Your network is firewall-protected. The UDP broadcast may not be permitted unless Port 10024
is open.
If you are unable to locate Talon, have your network administrator ensure it is on the same physical
and logical section of your network and that broadcast traffic is allowed on port 10024 with a
broadcast address of 224.0.0.212
