Getting Started
Before you can use your Osprey Talon encoder, you first need to set up and configure it. This chapter provides 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
The Osprey Talon encoder, an easy-to-use streaming device, allows you to:
been identified on the network any HTML browser can be used to configure your encoder.
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.

Osprey Talon User Guide
Introducing Osprey Talon
Osprey Talon G2, G1 and G1H hardware-based streaming contribution encoders are designed for A/V and broadcast customers tasked with delivering quality video via RTMP, RTP, and UDP over the unmanaged internet.
Talon G1 and G2 can ingest video via 3G-SDI, HDMI, or Analog Composite (CVBS)
Talon G1H supports HDMI and CVBS.
Each Talon encoder uses the same web interface and Osprey BOSS utility to access and configure their features. Functions that are not part of that model are not visible in the web page.
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 thumb drive into the USB port on Talon. After a minute, remove the thumb 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 computer 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 for the first time 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.

Talon G2 H.264 Encoder
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.

2.0 System Control
This tab accesses most of the administrative functions of the Talon.
Talon IP Setup
By default, Talon receives its IP address via DHCP. If you need to use a static address it can be set in the IP setup dialog box on the System Control page. If you are not familiar with the settings found here check with your system administrator before changing any settings.
Feature (default) Description
IP Address Automatically Assigned Sets the IP address
Netmask Automatically Assigned Sets the netmask
Gateway Automatically Assigned Sets the gateway
Use DHCP Checked Enables/Disables DHCP
DNS Server IP (1 and 2) Automatically Assigned Specifies Domain Name Server
NOTE: When configuring static IP addresses, Talon requires all variables to be filled in. Static addresses without Netmask, Gateway and two DNS servers may fail. Osprey Boss may not be able to find a Talon with a failed address.
15
Osprey Talon User Guide
Firewall Configuration
By default, Talon’s configuration and control webpages can be accessed by any web browser that can reach it on the network. To add another level of security, users can enable the Talon firewall. Enabling the firewall effectively prevents any browser from connecting to Talon unless it is included on the “Management IP Address” whitelist. Simply add the IP address of the computer you wish to configure or control Talon. [Example:192.168.1.124] Additional addresses can be added, separated by a comma.
CAUTION: Before enabling the firewall, be certain that the Management IP Address box contains at least one address, and that address is the one you want to use for access. Activating the firewall with an empty address box will result in losing access to Talon.
Session Timeout
To prevent accidental unauthorized access, the Talon webpage will timeout after five minutes of inactivity. To rejoin the session you will need to login.
16
Osprey Talon User Guide
3.0 Device Management
Device management tasks allow the configuration of operating system features. These features aren’t accessed on a regular basis because they are not involved in the configuration of the encoder itself.
Set Name
The model designation for Talon is loaded as the default device name. To easily distinguish multiple Talons, you can create a new name here.
Set Password
The default password is “osprey”. To maintain device security, it is recommended you change the default password.
Reboot
Reboot performs a complete power reset of the device. Make sure you save all your settings before rebooting.
Update Firmware
Osprey provides periodic firmware updates for Talon. There are two methods to perform the update.
17
Osprey Talon User Guide
Updating via the Talon Web Page
From the DOWNLOADS section of the Osprey Video webpage, download the most current Talon update file.
Login to the Talon via the web page and click the System Setup tab.
Click the Update Firmware tab.
From Explorer select the Image file you downloaded from Osprey Video.
Click Upload and Update
Talon will install the new image and automatically restart.
You may receive a warning depending on the size of the update file. Simply wait until the upload completes.
18
Osprey Talon User Guide
Talon will display this upload success screen and begin the actual update process. This could take several minutes. When the process is complete, Talon will display the Login screen.
Updating via Thumb Drive
If you cannot access the Talon web page, it is possible to update directly from a USB thumb drive.
IMPORTANT: Because you will be updating from a pre-boot environment, the thumb drive must not be larger than 2GB.
Insert a thumb drive in your host computer. Format the thumb drive as FAT (do not use FAT32). Paste the image file to the root of the thumb drive. Insert the thumb drive in the Talon USB port. Restart the Talon. Wait until Talon shows a steady blue light beneath the On/Off switch. Remove the thumb drive. If you do not remove the thumb drive, Talon will update again on reboot.
NOTE: For all image updates
Passwords and encoder settings are not preserved by the update process.
19
Osprey Talon User Guide
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 up to 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
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.
20
Osprey Talon User Guide
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.
21
Osprey Talon User Guide
6.0 Encoder Configuration
All configuration for actual encoding is found under the tab marked “Stream (1)”. If your interface doesn’t have a tab marked “Stream” simply click on the tab marked “+” and one will be created automatically. Additional streams may be created by clicking the “+” up to the limits of the Operating Mode.
Stream Capacity
Although the interface will allow the adding of a stream, this does not mean that the encoder will support all the configured streams simultaneously. Capacity is dictated by the size of the input signal.
Input Size Stream Capacity
1080p60 1 x 1080p30 or less Only 1 stream allowed
1080i 1 x 1080p30 & 1 x 720p or 3 x 720p30
3 x 720p
NOTE: Exceeding recommend capacity will result in dropped frames and audio problems. NOTE: Stream capacity is not affected by bitrate. For best results, don’t exceed 20Mbps.
22
Osprey Talon User Guide
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 stream only. Note that the button color changes to indicate the status of the encoder.
Clone
Often a user wants to create second stream that is very like 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.
Status
Below the buttons is a status message. Encoder status including error messages is displayed here.
23
Osprey Talon User Guide
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 power-up 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. (not available on AH models)
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 LC Mode that the audio originate either from the SDI source or the Analog source.
16:9
If your input is SD, checking this box will set the aspect ratio of the bitstream to 16:9. If the input is HD this setting is ignored.
24
Osprey Talon User Guide
Encode Profiles (RTMP/RTP only)
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.
Video Rate Control
Select VBR for Variable Bit Rate. (default) Select CBR for Constant Bit Rate. (only recommended when your CDN requires it)
NOTE: CBR is only supported for progressive output. Talon CBR does not allow the use of B frames.
Maximum Delay
This setting adjusts the amount of internal buffer the encoder can 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.
25
Osprey Talon User Guide
Advanced Settings
When an Encode Profile is selected, Encoder Setup displays a shortened menu. To view all 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 the variables will be available to you. Below are some of the settings available from the Custom menu.
26
Osprey Talon User Guide
Video Resolution
This pull-down menu sets the video 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. ¼ will be one quarter 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.
27
Osprey Talon User Guide
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.
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 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/RTMPS
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 video 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.
URL
This is where you manually insert the URL for the RTMP server. You must add the “rtmp://” in front of the address when you enter it. The entire URL should be entered in the box, i.e. “rtmp://Servername(or IP address)/ApplicationName/StreamName”. For complex addresses it is best to copy and paste the address from the host control computer.
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.

Osprey Talon User Guide
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, 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 or Unicast 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 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.
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 thumb drive or Network Share as a location. For detailed information see the “Save to File” instructions below.
TS LowLat Mode (default FALSE)
When set to “True” this mode reduces encoder latency by roughly 30%. Low latency can result in exchanging video quality for speed. For most high motion video, consider using the default setting “False”.
30
Osprey Talon User Guide
RTP
RTP is a delivery protocol like 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:
v=0 o=- 653 1 IN IN4 TALON_IP s=Osprey Talon streaming video t=0 0 m=audio USER_SELECTED_PORT(audio) RTP/AVP 97 a=tool:Talon a=recvonly a=type:broadcast c=IN IP4 DESTINATION_IP a=rtpmap:97 mpeg4-generic/48000/2 a=fmtp:97 streamtype=5; profile-level-id=14; mode=AAC-hbr; config=0990; sizeLength=13; indexLength=3; indexDeltaLength=3; constantDuration=1024 m=video USER_SELECTED_PORT(video) RTP/AVP 102 c=IN IP4 DESTINATION_IP a=rtpmap:102 H264/90000 a=fmtp:102 packetization-mode=1 b=AS:200

NOTE
:
Save to File
Talon does not have internal file storage. To save video to file there are two options available. You may save to a USB device, or a shared network location.
Select “Save to File” under the “Output Format” menu and one of your “Stream” tabs will be dedicated exclusively to saving encoded output as a .ts file. Enable “Save to File” under the UDP output format tab to create a UDP stream and simultaneously save a .ts file to your selected location.
Maximum available file size varies depending on the formatting of the drive. To avoid creating oversized files, Talon creates files in 2GB segments. Talon appends a _0 to each filename. When the maximum file size is reached, Talon creates an additional file of the same name and appends _1, and so forth.
File Naming
In the “Path and Filename” dialog, enter the filename. The _0.ts will be added automatically. Users may also specify parameters to automatically be replaced in output file name. This allows save to file without overwriting the previous file or to name files in a more convenient manner. %d (date YY-MM-DD), %t (UTC formatted time THHmmssZ), & %v (video bitrate) are all supported. For example: MyFile_%d would become MyFile_2017-13-02_0.ts MyFile_%v would become MyFile_1500K_0.ts MyFile_%t would become MyFile_T131800Z_0.ts test_%d_%t would become test_2007-13-02-T121800Z_0.ts
NOTE: Talon will not create folders or sub-folders on the drive. To place a file in a sub-folder, be certain the folder exists before inserting the drive into Talon. To save the file to a folder enter “foldername/filename”.
Destination: USB Flash Drive
A thumb drive must be properly mounted for a Save-to-File encode to work. When the words "USB Device" appear in the
"Output Device" pull down menu, a thumb drive is mounted and available. To ensure the device is properly unmounted when the stream is over click the icon to the right of the "Output Device" box before removing your thumb drive. A ‘save to file’ stream must have the thumb drive in place or the encode will fail.
Do not attempt more than one
‘Save-to-File’ operation at a time. Do Not use a USB hub.
33

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 specific 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.
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

Appendix A: Encoding Profiles
Encoding profiles serve as a guideline for the selected resolution. The bitrates are set near the minimum end of the spectrum. You may find that your encode requires a higher bitrate. The bitrate can be changed without changing the rest of the profile settings. All presets use H.264 video codec, main profile and AAC-LC audio with the exception of LOW which uses Baseline profile. All GOP sizes are 2 seconds.
