Quick Start

This section helps you get up and running quickly with your VGADVI Broadcaster:
l Step 1: Physical setup and power on
l Step 2: Confirm signals from input sources
l Step 3: Admin discovery and login
l Step 4: Setup the video source
l Step 5: Configure the channel
l Step 6: Record the stream
Before you get started, make sure you have:
l an HD source (i.e. a computer, a tablet, or a phone)
l the appropriate cables or adapters to convert the output to DVI (if needed)
l optionally, an audio source such as a microphone or the headphone jack from a laptop (note that the audio
signal sent over HDMI cables is not supported)
l ideally, a network with Dynamic Host Configuration Protocol (DHCP)
l a computer with a web browser connected to the same network (this is referred to as the “admin” computer in
the steps below)
These instructions include steps for setting up and configuring audio. Skip these optional steps if you do not want to configure an audio source at this time.

Step 1: Physical setup and power on

Complete the following steps to prepare and power on the system. Refer to the Front and Back Panel View section for your system to locate the appropriate ports.
1. Turn on your HD source and connect the output cable to the DVI-I input port on the front of the device.
2. (optional) Attach a 3.5 mm audio cable from your audio source to the system’s audio input port.
3. If your network connection provides power overEthernet:
a. Connect the Ethernet cable to the system.
b. Connect the Ethernet cable to your network.
If your network connection does not provide power over Ethernet:
a. Connect the PoE injector into a grounded AC power source.
b. Connect an Ethernet cable from the Ethernet switch port on your network to the RJ-45 connector
(labeled In) on the PoE injector.
c. Connect an Ethernet cable from the RJ-45 connector (labeled Out) from the PoE injector to the RJ-45
Ethernet port on the back panel of the VGADVI Broadcaster.
4. Wait for the system to complete the power up sequence. The green power LED is illuminated when boot up is complete.

Step 2: Confirm signals from input sources

Once the VGADVI Broadcaster is powered up, you can confirm that signals from input sources are received by the device.
1. To ensure an input source is properly connected to the DVI input port, connect a monitor to the DVI output port on the VGADVI Broadcaster.
2. View the monitor to confirm a signal is sent to the DVI input port.
3. To confirm high quality data is captured from an S-video input source, connect the source to an S-video or composite receiver, such as a TV or monitor before connecting to the VGADVI Broadcaster and confirm that a high quality signal is generated.
4. To ensure an audio signal is sent to the VGADVI Broadcaster, connect a speaker or headset to the audio output port and listen to the captured audio.
Now you are ready to capture, record and stream.

Step 3: Admin discovery and login

The VGADVI Broadcaster is managed from a web interface. This interface acts as a configuration utility and system monitor. The first time you access the web interface you may not know the IP address of the device.
The steps below use DNS-based service discovery (a type of zero-configuration networking) to access the device. Depending on the operating system on your admin computer you may need to install some software before you can use DNS-based discovery.
Table 5 Installing Bonjour Print Services
System Action Needed
Microsoft Windows You must install Bonjour Print Services:
1. Use the following URL - http://support.apple.com/kb/DL999
2. Click Download.
3. Follow the system prompts to download and install the application.
MacOSX The Bonjour software used for service discovery is built into the Mac OS. No special actions are
needed.
Linux The Avahi implementation used for DNS-based discovery is shipped with most Linux
distributions. If necessary, check with your administrator to ensure you have the Avahi package installed.
This quick start is meant for systems that support DHCP and DNS, however if your system does not support either protocol, refer to Connect to the Admin Interface for other discovery methods. Return here when prompted for the web interface user name and password.
You are able to access the system's web interface on the local network by specifying its serial number in a web browser on your admin computer.
1. Find the system’s serial number. It is printed on a sticker on the back of the device.
2. Type the following string into the address bar of your web browser on your admin computer and press Enter.
(<serial> is the serial number of your VGADVI Broadcaster):
http://<serial>.local/admin For example: http://3D24A1.local/admin
3. Enter the user name and password then click OK. The administrative user is ‘admin’. Initially no password is set.
To set a password follow the procedure outlined in Setting and Changing User Passwords.
4. Optionally, navigate to the Network link under the Configuration heading and note the IP address of the
system.

Step 4: Setup the video source

When a source device, such as a camera or tablet is connected to an input port, the VGADVI Broadcaster automatically recognizes the source and adds the source to the Stream Setup menu in the Web Interface.
1. From the web interface, click on the Info page; the info page opens displaying the live stream and the stream
URL. This is the link you can share with your viewer to view the live broadcast.
Source setup is complete. The system automatically detected and adjusted the image capture settings at start up and will continue to adjust every 60 seconds during operation (interval is configurable). The system’s goal is to produce the best quality captured image given the source equipment used. Generally no further configuration tweaks are needed.

Step 5: Configure the channel

Now that you confirmed the system detected your source and you are satisfied with the captured image, it’s time to configure a channel to share the captured image with your streaming users and prepare the source for recording.
Review and configure the channel:
1. From the web interface, click Stream Setup. The Steam Setup page opens displaying configuration settings for
DVI and S-Video channels.
2. No need to change anything right now. Review some of the default settings. The four most useful settings to
know about are codec, frame size, frame rate and bitrate.
a. The codec is set to H.264 by default.
b. The frame size should reflect the resolution provided by your source. You can set it to something different
by typing in the fields or selecting an option from the different sizes shown. Scaling the image (making it larger, smaller, or different aspect ratio) takes some processing power, so it’s always best to leave this at the value detected by the system unless you know it is wrong or know you need to scale the size.
c. The frame rate limit is set to 30. This means the system won’t spend extra computing time to attempt to
receive more than 30 frames per second. For perspective, NTSC TV signals use 24 frames per second and most hand-drawn animations show only 12 unique frames per second.
d. The bitrate is automatically calculated based on the resolution of the input signal. Raising this value uses
more system processing power and more bandwidth.
You may now optionally add audio to your channel:
3. Scroll to the bottom of the Stream Setup page and ensure the Enable audio checkbox is enabled (enabled by
default) for the audio source to which you connected your 3.5 mm audio cable.
4. Leave the default PCM 22KHz format and audio bitrate.
5. Click Apply.
Your stream setup is complete. Since most of the steps are pre-configured; you are up and running with a stream very quickly. You can share the live broadcast link with your viewers on your local area network (LAN). Depending on your internet connection and upstream bandwidth, you may need to adjust the video bitrate down before sharing over the internet.

Step 6: Record the stream

The device is set up and streaming. This may be all you need, but if you like, you can also record the stream.
To record the stream:
1. From the web interface, click the red Start button at the top of the menu; the text at the top of the screen
changes to indicate the recording is starting, then indicates the length of time since the recording started.
2. Click the black Stop button; the recorder stops.
3. To view the result, click RecordedFiles; the recorded files page loads and a file list appears that displays your
newly recorded stream snippet.
4. Click the file name to download and view your recording.

What’s Next?

Now that you have a source setup and ready to stream, you can fine-tune the system to your exact requirements. You can look at topics such as:
l Customize your channel
l Stream your video
l File and Recording Transfer
l User Administration
When you have completed system tuning, make sure to back up the device configuration using the procedure described in:
l Save and Restore Device Configuration

Understanding User Privileges

The VGADVI Broadcaster has three users: admin, operator and viewer. The user account names cannot be changed and the accounts cannot be disabled. By default, none of the accounts have passwords.
Admin
The admin account is the main operator used for all device configuration. This user has access to all options in the web interface.
Operator
The operator account is a subclass of the admin account. The operator can log in and view all configuration items but may only make changes to a small number of options. This account is intended for an operator to start and stop recordings, download recordings, or perform network diagnostics.
Viewer
The viewer account is for all end-users who are permitted to view the streamed channels. By default, when there is no password, users are not prompted for a username and password when viewing a channel. A username and password prompt appears when there is a viewer password set.

Setting and Changing User Passwords

The VGADVI Broadcaster's three static users are: admin, operator and viewer.
None of the accounts have passwords assigned by default, but since both the admin and the operator user have access to the web admin interface, you should always have a password for both admin and operator accounts. Refer to your system administrator for your organization’s specific password requirements.
21
VGADVI Broadcaster User Guide 1-2 User Administration
Passwords are case sensitive and can use all alpha-numeric keys in the ASCII range. Your password can be up to 255 characters long, but should not include any spaces.
Setting a user’s password causes the user to be logged out. Be ready to log back in with the new admin password or have operators and viewers log in with the appropriate new password. Viewers may need to refresh their browser window or press play in their media player.
If you lose the admin password, refer to the section Overcoming Lost Passwords.
To set a user password:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Access passwords link in the Configuration menu; the password configuration page opens.
4. Highlight and delete the current password for your selected user (the password is currently masked as
dots).
For security reasons, the current password appears as eight dots regardless of password length, and even if there is no password set.
5. Highlight and delete the confirmation password for the selected user.
6. Select the user’s password field and type a new password for the user.
The new password must have between 1-255 alpha-numeric characters or special characters with no spaces. Passwords are case sensitive.
7. Select the user’s password confirmation field and confirm the new password.
8. Click Apply.
9. If you were logged in as the user whose password you just changed, you are logged out and must log
back in with the new password. If you added or changed the viewer’s password, all viewer’s stream will pause until they log in with the new password.
If desired, you may specify multiple account passwords on the same page before clicking Apply.

Removing User Passwords

If you want to remove passwords for one or more user accounts, you may do so via the web interface. If you don’t remember the admin password, refer to the section Overcoming Lost Passwords.
22
VGADVI Broadcaster User Guide 1-2 User Administration
Clearing a user’s password will cause that user to be logged out. Be ready to log back in with the new admin password. If viewers are watching the broadcast when the viewer password is cleared they will be logged out. Viewers may need to refresh their browser window or press play in their media player to trigger the login prompt.
To clear a user’s password:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Access passwords link in the Configuration menu; the password configuration page opens.
4. Highlight and delete the current password for your selected user (the password is currently masked as
dots).

5. Highlight and delete the confirmation password for the selected user.
6. Click Apply.
7. If you were logged in as the user whose password you just cleared, you are logged out and must log
back in without a password. If you cleared the viewer’s password, all viewers’ stream will pause until they log in without a password.

Overcoming Lost Passwords

If you have lost the password for the operator or viewer account, you can log in to the web interface as admin and reset the password using the procedure described in Setting and Changing User Passwords.
If you have lost the admin password you will need to reset the device to factory defaults, which resets to the default blank admin password. See Restoring Factory Configuration.
After resetting to factory defaults, you can restore a configuration file with your known good configuration. Remember to set user passwords after loading a configuration. Passwords are not saved in the configuration file. See Save and Restore Device Configuration.

Changing the logged-in user

When you log in to the web interface as admin or operator, your browser remembers this configuration and automatically logs you in as the same user when you go back to the site.
23
VGADVI Broadcaster User Guide 1-2 User Administration
Sometimes you need to change from operator to admin, or vice versa.
To change the logged-in user:
1. Exit your browser completely, or open a different browser (i.e. Internet Explorer, Chrome, and Safari are
different browsers).
2. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin

VGADVI Broadcaster User Guide 1-5 Restrict Viewers by IPAddress
1-5
The VGADVI Broadcaster permits you to restrict which computers can access broadcasts by building a list of allowed and/or denied IP addresses.
If your viewer account has a password, your viewers must connect to the device from a computer (or gateway) with a permitted IP address and must also supply the username and password before they can view the broadcast.
To restrict access by IP address you need to know the IP addresses, or range of addresses for your viewers. By default all IP addresses are allowed to connect to the broadcast.
If you’re not familiar with creating allow/deny lists, refer to the examples below this procedure for assistance with crafting your lists.
Restrict Viewers by IPAddress
IP address restriction is valid for the viewer only and does not affect the web interface or the mobile configuration interface.
IP Address restriction is not configurable per channel. Restrictions affect all broadcasts / streams from the device.
To restrict viewers by IP address:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Access passwords link in the Configuration menu; the password configuration page opens.
4. Type allowed IP addresses or address ranges in the Allow IP’s field. Separate addresses with a comma.
5. Type denied IP addresses or address ranges in the Deny IP’s field. Separate addresses with a comma.
6. Click Apply.
If a user attempts to connect to the stream from a disallowed IPaddress, access is denied. If connecting by internet browser, the message "IPaddress rejected." is displayed.
The following table describes the applicable fields.

Table 14 IP Based Restriction Fields
Label Description/Options
Allow IP's Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are permitted to view broadcasts from the device, provided their IP address is not in the Deny IP’s list.
To allow all (except IP addresses in the deny list, if any), leave the field blank.
You can use the Allow list by itself, or in conjunction with the Deny IP’s list as an exception to a rule in the allow list.
Deny IP's Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are not allowed to view broadcasts from the device, unless their IP address is in the Allow IP’s list. If a specific IP address is in both lists, access to the stream is denied.
You can use the Deny list by itself, or in conjunction with the Allow IP’s list as an exception to a rule in the allow list.

Examples

Allow List with Distinct IP Addresses
The simplest allow/deny list is to use the list of known IP addresses to craft a list of allowed IP addresses. All other addresses are denied access to the broadcast.
For example if your device is accessible on your local area network (LAN) and you want to make sure only the CEO’s specific desktop, laptop and tablet computers (with IP Addresses 192.168.1.50, 192.168.1.51, and
192.165.1.75, respectively) can connect to the broadcast, construct the following allow list:
Allow: 192.168.1.50, 192.168.1.51, 192.168.1.75
Allow List with a Range of IP Addresses
Sometimes you’ll want a range of computer IP addresses to connect to your device. This may happen when you have one range of IP addresses assigned to desktop computers (i.e. in the range 192.168.1.1 to 192.168.1.100) and another range assigned to boardroom computers (i.e. the range 192.168.1.200 to 192.168.1.250). If you only want the boardroom computers to connect to broadcasts from the device you can specify the range of boardroom IP addresses rather than needing to type in each individual address. The allow list looks as follows:
38
VGADVI Broadcaster User Guide 1-5 Restrict Viewers by IPAddress
Allow: 192.168.1.200-192.168.1.250
Note that we could have specified two of the IP addresses in the previous example as a range.
Allow List with a Range of IP Addresses and One or More Specific IP Addresses
Putting the first two examples together, we want to permit access to IP addresses in the range of boardroom computers (192.168.1.200-192.168.1.250) and also want to add the desktop, laptop and tablet computers of the CEO (IP addresses 192.168.1.50, 192.168.1.51, and 192.168.1.75, respectively). Note the first two IP addresses are consecutive, so they can be added as a second range. Add these IP addresses to the list as follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Your list can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny List with Distinct IP Addresses
Another simple allow/deny list is to use the list of known IP addresses to list specific denied IP addresses. All other addresses are allowed access to the broadcast.
For example imagine your device is accessible on your local area network (LAN) and you want to allow any computer on the LAN can access the stream except your publicly-accessible boardroom (with IP address
192.168.1.211). You can use the following deny list (leave the allow list empty) to permit all computers except the boardroom computer:
Deny: 192.168.1.211
As with Allow lists, your deny list can specify a range of IP addresses, and can specify multiple ranges or distinct IP addresses in a comma-separated list.
Allow List with a Range of IP Addresses, Distinct IP Addresses, and an Exception
Building on the previous examples, consider the situation where you want the CEO’s computers (192.168.1.50,
192.168.1.51, 192.168.75) and all boardroom computers (192.168.1.200-192.168.1.250) to access the broadcast, with the exception of the public boardroom computer (192.168.1.211). Use both allow and deny lists to create the rule as follows:
39
VGADVI Broadcaster User Guide 1-5 Restrict Viewers by IPAddress
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Deny: 192.168.1.211
Both lists can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny List with a Range of IP Addresses
Converse to the previous examples, consider the situation where you want every computer on the network to access the broadcast, with the exception of the CEO’s desktop, laptop, and tablet computers. Additionally, boardroom computers should not be permitted with the exception of the cafeteria computer (IP address
192.168.1.222).
The deny list is an "exception" list for the allow list. So to craft the rule described above we need to allow all the computers in the local subnet, then deny specific sub-ranges including two groups of boardroom computers ensuring the cafeteria computer's IP address is not in the deny list:
Allow: 192.168.1.1-192.168.1.250
Deny: 192.168.1.200-192.168.1.221, 192.168.1.223-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75

In addition to fine tuning channel settings such as frame rate, resolution and bit rate to ensure optimal use of resources while streaming a quality video, there may be circumstance when you must fine tune the video input source.
Fine-tune source configuration
Changing how source images are displayed may cause undesired results, for example experimenting with the PLLsetting may result in the image not being displayed properly. It is a good practice to backup your configuration settings so that you can revert back to a good configuration if the changes that you made are not desirable. See Save and Restore Device

Video is too bright, too dark or washed out
If the video from the source is too light, too dark or washed out, use the offset and gain controls together to optimize image quality. Increasing the gain amplifies weak signals but also increases noise, you must balance offset and gain values to achieve the best quality image.
Adjust these settings by the smallest values possible; compensate for a large change to one by making a large change to the other. Setting both offset and gain to high values can result in poor video quality.
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin

Remove the combing effect on images
When frames are interlaced, artifacts from one frame may appear on the next frame. This occurs when a fast motion video is interlaced. Since each frame is captured from a different point in time, the action captured in one frame is carried over to the next frame. The result is a blurred image and horizontal lines running across the video.
To convert an interlaced source signal to a non-interlaced signal.
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.

Force the video source to use a specific resolution

Extended display identification data (EDID) is data provided by a video display device (usually a monitor) to describe its capabilities to a video source. The video source uses the EDID to determine the capabilities of the monitor to determine the resolution, color depth and other settings that the monitor can support. EDID is crucial for DVI sources but mostly ignored by VGA sources.
When you connect the VGADVI to a video source, the video source sees the device as a monitor. Just like a monitor, the VGADVI contains the EDID that is used by the video source to determine the video signal to send.
Upload a new EDID
In most circumstances the factory installed default EDID, is sufficient. However, there may be some cases where a video source uses resolutions that you do not want to use. In that case you can choose an EDID that forces the video source to use a specific resolution.
The uploaded EDID is permanently installed on your VGADVI and will always share this EDIDwith the video input source.

l Codec and file format compatibility
l Adjust video quality
l Upscale or downscale your video image
l Control the matte (black bars) in the video output
l Unstretch the output video
l Limit the frame rate
l Adjust key frame interval

Choose a codec to maximize your stream quality

Before you begin recording and streaming content from a channel, you must select the codec that will be used to compress the channel’s video and audio content. Deciding on which codec to use depends on how you prioritize the following criteria:
l Compatibility with streaming formats and file playback options
l Size of the compressed file
l Compression speed
l Image quality
For example, if you require a high quality image, the trade-off might be a larger file size, or slower compression speed. If you require live streaming and therefore cannot tolerate slow compression, the trade-off might be a lower resolution. The table below highlights the advantages and disadvantages of supported codecs.
Once you select video and audio codecs a list of available video format and standards specific to the selected codec is generated and displayed. You can provide the URLs and files to participants to view the broadcast, see

Adjust video quality

After sources are connected and channels are created, adjustments can be made to address the different bandwidth and devices used by the sharing destinations. Ideally you want to choose formats that will reach the majority of your participants.
Default values have been carefully selected to provide maximum performance in most environments. In most cases it is not necessary to change the encoding settings.
To encode your video stream:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, click Stream Setup; a Stream setup page opens.
4. Click Video encoding preset to define how a video stream is encoded. Choose one of the following:
Value Description
High quality Choose this option when you are streaming content such as slides or slow moving
video.
High speed Choose this option when you are streaming medium to fast moving video.
Default Factory default is high speed.
66
VGADVI Broadcaster User Guide 3-2 Fine-tune channel configuration
5. Click Video encoding profile to limit or include video formats that are supported. Choose one of the
following:
Value Description
Baseline Choose this option when streaming to an application that requires robustness
and cannot tolerate data loss, for example video-conferencing.
Main Choose this option for standard-definition broadcasts. This is the default.
Default Choose this option when video is viewed for broadcast and disk storage
applications, particularly for high definition television application such as Blu-ray disk storage format and HDTV broadcast service.
Video encoding profile and preset can be set when H.264 codec is selected.
6. Check the check box for Enhanced compatibility mode (h.264 slicing for RTP) to provide operating
stability when the video and audio stream are not supported by the viewer’s equipment. When this feature is enabled, each frame is sub divided into one or more slices. Each slice is self-contained, all information for decoding is available within the slice. This is valuable when packet size exceeds the maximum allowable amount. Therefore losing a slice will not impact the entire frame.
Packet slicing adds to overhead and impacts compression efficiency. A value can be set when H.264 codec is selected.
7. Set the Rate Control mode when H.264 and MPEG4 codecs are set. The values define how strictly the
codec adheres to the specified bitrate. Choose one of the following options from the Rate control mode drop-down menu.
Value Description
Relaxed Choose Relaxed when streaming multimedia content and there is available
bandwidth, the quality of the multimedia stream must be constant and the bit rate can vary.
Balanced Choose Balanced when streaming multimedia content that has periods of high
and low bit rates. The target bit rate is met by averaging the bit rate.
Strong Choose Strong when streaming multimedia content when limited bandwidth is
available and a constant frame rate is required. There may be a decrease in video quality if there is a lot of motion.
8. Click Apply.

VGADVI Broadcaster User Guide 3-2 Fine-tune channel configuration

Upscale or downscale your video image

If your source input is larger than your desired output frame size or if you want to stream a less bandwidth­hungry version of the content, you can downscale the source by specifying a frame size that uses the same aspect ratio. By contrast you can also enlarge the image by selecting a value that is larger than the source resolution.
The VGADVI Broadcaster conveniently provides a list of common aspect ratios and different frame sizes at each ratio on the Stream Setup page.
For example:
l input signal resolution is 1920×1080 (a 16:9 aspect ratio)
l select another 16:9 frame size such as 1280×720
The smaller frame size will downscale the image and use less bandwidth to transmit.
If you select a frame size that is not the same aspect ratio as your source, the result is one of having a matte (bars) appear around the image, or the image is stretched. See Control the matte (black bars) in the video
output for details.
Resizing a video can be more resource intensive rather than leaving the video at a native resolution. Although you can change the resolution at the VGADVI Broadcaster level, it is less of a burden on your system resources if you can change the resolution at the source level. However if that is not feasible, you can download an EDIDto the VGADVI Broadcaster to force the source to send a specific resolution. See Force the video source to use a specific resolution .
To change the frame size of your video, follow the steps below.
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Click Stream Setup; the stream setup page opens.
4. Scroll to the frame size parameter.
5. Deselect Use current signal resolution as frame size, if it is selected.
68
VGADVI Broadcaster User Guide 3-2 Fine-tune channel configuration
6. Choose a resolution from the links on the right, or type a frame size into the Frame size fields.
7. Click Apply.
The final frame size can be larger when Picture in Picture layouts are used.

Control the matte (black bars) in the video output

By default, the VGADVI Broadcaster makes sure that the aspect ratio of input signals is preserved when the output is streamed. If an input video signal doesn't match the encoded frame aspect ratio, bars are added to the sides or top and bottom of the encoded stream when the output is streamed and recorded. The color of the bars is defined by the Background color selected on the Stream Setup page. See Select the background
color for your channel.
For example:
l Input signal resolution is 720×480 (a 3:2 aspect ratio)
l encoded resolution is 640×480 (a 4:3 aspect ratio that is narrower than the input resolution)
Borders are added to the top and bottom of the image to preserve the wider ratio of the input.
69
VGADVI Broadcaster User Guide 3-2 Fine-tune channel configuration
For example:
l Input signal resolution is 720×480 (a 3:2 aspect ratio)
l encoded resolution is 1280×800 (a 16:10 aspect ratio that is wider than the input resolution)
Borders are added to the left and right of the image to preserve the narrower ratio of the input.
The left and right side border are not guaranteed to be of equal width.
If you are seeing bars on your image but would rather have the image fill the whole screen you have to options:
1. Change the output frame size to match the aspect ratio of the input.
2. Stretch the image to fit the output frame size aspect ratio.
These two options are described below.
Match the output frame size to the aspect ratio of the source signal
To change the output frame size to match the aspect ratio of the source:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Click the channel's Stream Setup; the stream setup page opens.
4. Scroll to the frame size parameter.
5. The simplest option is to select Use current signal resolution as frame size and click Apply. You can
alternatively select it briefly to note the current video signal resolution, then deselect it and follow the steps below.
70
VGADVI Broadcaster User Guide 3-2 Fine-tune channel configuration
6. Look for the source aspect ratio in the list of aspect ratios provided.
a. If the source resolution is on the list, choose another resolution on the same line(i.e. with the
same aspect ratio).
b. If the source resolution is not on the list, use a calculator to get a factor of the source resolution
and enter it in the Frame size fields.
7. Click Apply.
Stretch the image
To remove the matte(black bars) by stretching the image to fit your output frame size:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, click Stream Setup; the stream setup page opens.
4. Deselect Keep aspect ratio.
5. Click Apply.
71
VGADVI Broadcaster User Guide 3-2 Fine-tune channel configuration

Unstretch the output video

By default, the VGADVI Broadcaster makes sure that the aspect ratio of input signals is preserved when the output is streamed. If this default was overridden or if the channel was created in a version of the software earlier than 3.11.0, the image is stretched to match the output frame size. The effect may be subtle and may not be problematic for you, but if you want to resolve this it is very simple to do.
To preserve the source aspect ratio:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, click Stream Setup; the stream setup page opens.
4. Select Keep aspect ratio.
5. Click Apply.
Unstretching the image causes a matte (black bars)to appear on the sides or top and bottom of the output. To remove these see Control the matte (black bars) in the video output.

Limit the frame rate

Limiting the frame rate sets a frame rate value that is lower than the maximum frame rate at which the device can encode images (the maximum is 30). Reducing the frame rate reduces the number of images captured by the device and reduces bandwidth usage.
The device's ability to maintain a set frame rate is based on several factors, for example:
l overall system load affects the ability for the device to process pixels;
l available bandwidth;
l the resolution value;
l the type of motion that is captured; and
l number of users accessing the stream.
72
VGADVI Broadcaster User Guide 3-2 Fine-tune channel configuration
When adjusting the frame rate, you may need to try different values to achieve the best outcome. The following table provides the performance expectations when typical settings are used.
Table 16 Performance expectations
Setting H.264 MPEG
Resolution 1920×1200 1920×1080
Video encoding preset: Quality 25-26 fps 13 fps
Video Encoding preset: Speed 27-28 fps 17-18 fps
To change the frame rate:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, click Stream setup; a Stream setup page opens.
4. Enter a value in the Limit frame rate field.
5. Click Apply.

Adjust key frame interval

The key frame interval feature specifies how often a key frame (a frame that contains all the pixels) is used when streaming the video. This setting also impacts how quickly a video moves through the frames when a viewer uses the search function of their media player.
Increasing the number of seconds between key frames can significantly reduce your bandwidth and system resource usage with minor impact to your video quality. A good rule of thumb is to keep the interval between 2 to 3 seconds and decrease the key frame interval as the motion increases. Try different settings and note changes in the video quality. If your video quality is poor and jittery you may need to decrease the interval between key frames. If you have unlimited bandwidth and system resources you can choose an option to stream key frames only.
To adjust the key frame interval:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, click Stream setup; a Stream setup page opens.
4. Scroll to the Key frame interval drop-down menu. Choose the number of seconds before the system
streams a key frame.

Each method of streaming media has strengths and weaknesses depending on your audience location, hardware resources and bandwidth. To help you to decide how to publish your content, you must first identify the number of viewers and how viewers will access your content. Are you streaming live video, or recorded video. Do you need to stream the content to one client (peer-to-peer), deliver a single stream to multiple clients (multicast), or provide web-based streaming where multiple clients can access the broadcast (Content Distribution Network).
The following table gives you a brief outline of the distribution options. A procedure to configure each distribution option follows the table.

HTTP Quickly stream content to viewers simultaneously. No set up is required. The
VGADVI Broadcaster is ready to stream content as soon as it is has power and an input signal. No other settings are required. Your audience need only access the URL of the broadcast and they are instantly connected. This viewing method is ideal for a small number of viewers since streaming uses your system resources and bandwidth. However a small amount of overhead is used for each viewer. For more information about using a HTTP streaming, refer to Stream content using HTTP or RTSP.

Content Distribution Network
Stream web content to many viewers simultaneously to any geographical location. A viewer accesses the broadcast from a website using a user name and password, if required. Using a CDN to host your broadcast is highly scalable and makes financial sense to website owners since you do not pay for additional server hardware or routing should your network traffic increase or decrease.
Using a CDN to stream live content allows you to reach a large geographically diverse audience and because CDNs perform format conversion, the stream is platform independent.
For more information about streaming to a CDN, see Stream content using a
Content Distribution Network.
The following options are available to stream video to a CDN:
Epiphan TV - test your video stream using Epiphan’s portal
using RTSP announce - stream live video to a content delivery network
using RTMP push - stream live video to a content delivery network
RTSP and RTMPstreaming provides the following advantages:
l viewers can watch the action as it unfolds;
l video quality automatically changes to adjust to changes in
bandwidth;
l reduced bandwidth usage since the player maintains a smaller buffer;
and
l viewers can scroll back through later sections of the video while the
video is streaming.

Multicast Streaming Stream content to a multicast IP address where it can be shared with
multiple viewers within the same LAN. All viewers receive the same stream at the same time. Similar to turning on a radio station, all listeners hear the same music at the same time.
This delivery method relies on network equipment that supports multicasting and is usually used in high bandwidth corporate LANs and not on Internet-based architectures.
This delivery method is useful for training sessions, when there is a specific timeframe when the audience will view the content. For more information about using multicasting for streaming your content, see: Stream content
using multicast streaming
l RTP/UDP transport standard is used to stream H.264 video when
unicast or multicast streaming is used. Each viewer retrieves an SDP file. SDP files can be stored on a streaming server, or opened by a media player. For multicast, the destination address is
l MPEG-TS UDP transport standard is used to stream MPEG-4 video
when unicast or multicast streaming is used. Each viewer retrieves a UDP address to add to their media player.
l MPEG-TS RTP/UDP transport standard is used to stream video when a
single port is used to stream video and audio via unicast or multicast. Each viewer retrieves a RTP address to add to their media player.
This option can be used to stream video and audio to an IP TV or set top box playlist.
To stream video outside of your LAN, use a CDN or configure port forwarding on your router. Refer to your Network Administrator; network configuration is beyond the scope of this guide.
The Publish Stream feature is available when the H.264 codec is set.

Retrieve stream URLs

The quickest and simplest way to deliver your content is to send the broadcast's URL to your viewers. You can provide separate URLs for each channel being streamed. Alternatively, one URL can be provided that includes all streams from all input sources. The format of the URL depends on the method you used to access the device, either through network discovery using the serial number or IP address.

VGADVI Broadcaster User Guide 4-1 Stream your video
Serial URLs must be on the viewer's LAN for the viewer to use this option.
Table 18 URL options
Access Method URLFormat
serial discovery http:// (or rtsp://)<s/n>.local:****
s/n is the serial number of the device
IP address http:// (or rtsp://)***.***.***.***:****

Configure streaming ports

For HTTP or RTSP streaming the only information required to view the broadcast is the URL and the port number used to stream the broadcast. Ensure each channel has a unique HTTP and RTSP port number and that the port number is not already being used.
When a channel layout is configured as independent streams, the following values are used for both streams.
To set the HTTP and RTSP streaming ports, follow the steps below.
1. From the web interface, click Stream Setup; a Stream setup page opens.
2. Scroll to Common settings.
3. Set the HTTP Streaming port to specify the port used to stream the HTTP broadcast. This value along
with the URL is used by viewers to access the broadcast.
89
VGADVI Broadcaster User Guide 4-1 Stream your video
The port number must be higher than 500 for HTTP. In the case of RTSP streaming this value is ignored.
4. Set the RTSP Streaming port when you are streaming live video. This value along with the URL is used by
viewers to access the broadcast. The default is 554.
5. Click Apply.

1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
5. From the web interface, scroll to the Info menu option. The Info page for the device opens.
6. Jot down the URL address. This is the address you can send to viewers or to create a link to your
broadcast.
Users must install Bonjour Print Services on their Windows or Mac computer to access the live Preview using the serial number. Log into the admin interface by IP address to see the URLwith the IPaddress instead of the serial number.

Stream content using a Content Distribution Network

A Content Delivery Network relies on geo-diverse CDN servers to receive and disperse web content to the CDN server closest to the user. The closer the server is to the user the faster the content is delivered. Streaming your content through a CDN allows you to stream any time, anywhere, regardless of the viewing device.
