AV.io SDI User Guide How AV.io SDI works

How AV.io SDI works

Once you’re ready to start capturing, you’ll need either a built-in or third-party application to capture video
and audio content with AV.io SDI.

The application communicates with AV.io SDI and negotiates a frame rate (frequency at which frames in a
video sequence aredisplayed) and frame resolution (sizeof a single video frame in pixels). Higher framerate
means smoother video capture whileresolution determines the aspect ratio of the video output as wellas its
resolution and degree of definition.

With the help of AV.io SDI, the content from your video source is automatically configured and captured on
your computerthrough your selected application. If the application requests a framesize that is smaller or
larger than your video source, AV.io SDI automatically scales the video for you. For consistent and widely
compatible output, audio is automatically resampled to 16-bit 48 kHz stereo audio.

No configuration required!

AV.io SDI User Guide Resolutions, capture ratesand aspect ratios

Resolutions, capture rates and aspect ratios

The resolution (also known as frame size or display mode) of a video signal, digital image, TV screen,
computer monitor or other display device is a count of the numberof pixels displayed horizontally and
vertically. For example the resolution 1920×1080 (which is 1080p) creates an imagethat is 1920 pixels wide
and 1080 pixelstall.

The aspect ratio of an imagedescribes the proportional relationship between its pixel width and height. The
resolution 1920×1080 (1080p) is quite a bit wider than it is tall. Theratio of its width to height is 16 to 9,
represented as an aspect ratio 16:9.

AV.io SDI outputs resolutions in commonly supported aspects ratios. Thetablebelow is a color-coded legend
for interpreting the tableof product resolutions below it:

Aspect

Common Use

Ratio

4:3

16:9

AV.io SDI generates a list of the followingpossible resolutions for your captureapplication to select for output
display:

Standard TV (NTSC/PAL) display and non-widescreen computer displays, SD-SDI
resolution

Widescreen (HD) TV displays (1080p, 1080i, 720p etc)

640×360 960×540 1920×1080

640×480 1280×720

Captured video content is output to your applicationat 15, 30 or 60 frames per second (your application
chooses one of these framerates) when captured over USB 3.0.

11

AV.io SDI User Guide Automatic image scaling & audio resampling

Automatic image scaling & audio resampling

If your source content is larger or smallerthan the frame size chosen by the application, AV.io SDI
automatically scales your source to match the desired frame size! No user configuration required!

AV.io SDI also automatically performsaudio resampling, meaning that no matter the bit depth or frequency
of audio through an SDI audio source, AV.io SDI automatically resamples your audio so that your application
gets a consistent audio sample rateand bit depth, even if you change the video source!

12

AV.io SDI User Guide Third-party applications

Third-party applications

AV.io SDI uses pre-installed drivers on your OS (called UVC drivers and UAC drivers) to communicate with
third-party applications and capture content. Due to AV.io SDI's use of UVC/UAC technology, there is no need
for driver installation. Just like a webcam, your AV.io SDI deviceis immediately recognized as a camera device
(likea web cam) and can be used to capturecontent via any UVC-compatiblethird-party application.

Third-party applications that work with AV.io SDI include, but are not limited to the following list. Try your
favorite capture application!

AV.io SDI User Guide Advanced configuration options

Advanced configuration options

The AV.io Config tool allows you to changeseveral settings to makechanges to your video capture experience
if necessary. Most users won’t need to use this utility for anything other than firmware updates, but advanced
users may find thesetweaks help them get the most out of their AV.io SDI.

These options include:

l Use input signal resolution

l Preserve aspect ratio

l Performance mode

l Audio selector for multichannel inputs

Use input signal resolution (disabled by default)

There are two key descriptors used in the process of video capture using a UVC-based device:

Extended Display Identification Data (EDID): The EDID describes to the video source, video player or
computer which standard video formats (resolutions, frame rates, etc.) aresupported by the capture device
as video input.

UVC Descriptor: TheUVC describes to the capture host computerwhich formats are available at the capture
device USB port.

AV.io SDI does not enforcea direct relationship between the input and output signals. The list of EDID and
UVC descriptionsare identical so that if the input and output formats are the same,the signal can pass
through without scaling. However, if input and output areset to different formats, AV.io SDI will automatically
upscale or downscale video to the format requested as output by the capture software.

The Use Input Signal Resolution option allows you to usea video format that is not included on the EDID
or UVC descriptors. When Use Input Signal Resolution is selected in the AV.io config tool, the input signal
format is added to the UVC descriptor, which allowsa 1:1 capture from the input video source. If the program
you are usingis compatible with the signal, you can capture your sourcein its original format.

For example,if your video resolution was 1680×1200, a resolution which is not on the EDID or UVC descriptor
list, normally you would have to select the closest possible resolution from the provided output descriptor list
in your capture application, and then AV.io SDI would automatically scalethe video up or down to that
format. However, if you select the Use Input Signal Resolution option, your capture application'slist will
have 1680×1200 as an option for output format.

There are two scenariosin which this feature willnot perform as expected.

26

AV.io SDI User Guide Preserve aspect ratio (enabled by default)

1. Not all third-party applicationsare able to support custom resolutions. AV.io SDI will send the custom
resolution to the application, but if it is unableto use the resolution, the application willoverrideany
AV.io SDI custom capturesettings.

2. In a Windows environment, due to restrictionsset by Microsoft’s Windows Hardware Quality Labs
certification, most graphicsadapters or driverswill not output resolutions not included in the EDID file
of the connected display device. In the scenario where a resolution that is not included in the AV.io SDI
standard resolution is requested,the Graphics adapter and driverwill apply the resolution requested
and then upscale it to AV.io SDI’s default resolution. This means the Use input signal resolution
featurewill not add a custom resolution to the UVC descriptor and the capturesoftware willbe limited
to the pre-defined resolutions.

Outside of these restrictions, the feature is recommended in any scenario where you wish the resolution of
your captured video to be identical to the original video source.

Preserve aspect ratio (enabled by default)

When enabled, your AV.io SDI preservesthe aspect ratio of your input signal by adding black barsto the sides
or top and bottom of the frame (only for caseswhen the application using the signalrequests a frame size
with a different aspect ratio). For example, with this option enabled, a 4:3 input signalgets black bars added
to the sidesof the image when viewed in an application that requests a 16:9 aspect ratio. With this option
disabled, the 4:3 image is instead stretched to fit the full 16:9 size.

Performance mode (enabled by default)

When enabled, your AV.io SDI enters and exits system suspend mode (i.e. sleep) fasterby disabling support
for the Suspend/U3 USB power state. This means AV.io SDI starts working again faster after your computer
wakes from a system suspend state, at the cost of increased power consumption. Disablingthis setting is ideal
in situations where powerconsumption needsto be monitored, such as battery preservation in laptops.

Audio selector for multichannel inputs (disabled by default)

YourAV.io SDI can capture one of the (up to) 8 audio channel pairs provided over SDI. Use this option to allow
your third party application to choose which audio pair to capture. By default, this is disabled and the first
audio pair is captured.

AV.io SDI User Guide Set custom resolution user modes

Set custom resolution user modes

The AV.io Config tool gives users the ability to specify custom resolutions. You can make use of up to three at
one time, so you don't have to worry about changing the list every timeyou changewhich source you have
connected. For settings to persist after power cycling, please allow 5 seconds before disconnecting or
restarting device.

To change the custom resolutionswith the AV.io Config tool:

1. If needed, install the AV.io Config tool. For detailsspecific to your OS, see Installthe AV.io Config tool.

2. Connect your AV.io SDI deviceto your computer, laptop or notebook.

3. Open the AV.io Config tool.

4. Select your AV.io SDI device from the list under the Devices heading.

If your video grabber is not displayed,pressthe Refresh icon to refresh the list of connected
devices.

6. To create a custom resolution,click the check box for one of the user modes. The grayed-out area
becomes open for changes.

7. Select the text box labeled Width, erase the numberthat is currently in the box, and type out the width
of the custom resolution you wish to use. Then do the samefor the resolution height in the text box
labeled Height.

8. Click Apply; Thecustom resolution you defined will now be added to the list of output resolutions that
you are allowed to select from the settings menu from the third-party application of your choice.

AV.io SDI User Guide Set custom resolution user modes

9. If needed, you may follow the same process for User mode 2 and User mode 3. If all three are
checked and applied, all threecustom resolutions selected willappear in the list of resolutions. You may
change the definition of any of thesethree resolutions at any time.

There are two scenariosin which this feature willnot perform as expected.

1. Not all third-party applicationsare able to support custom resolutions. AV.io SDI will send the custom
resolution to the application, but if it is unableto use the resolution, the application willoverrideany
AV.io SDI custom capturesettings.

2. In a Windows environment, due to restrictionsset by Microsoft’s Windows Hardware Quality Labs
certification, most graphicsadapters or driverswill not output resolutions not included in the EDID file
of the connected display device. In the scenario where a resolution that is not included in the AV.io SDI
standard resolution is requested,the Graphics adapter and driverwill apply the resolution requested
and then upscale it to AV.io SDI’s default resolution. This means the User modes feature will not add
the custom resolutionsto the UVC descriptor and the capture software willbe limited to the pre­defined resolutions.

Outside of these restrictions, the feature is recommended in any scenario where you wish to use a custom
output resolution.

Environmental Information

The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment. In order to avoid the dissemination of
those substances in our environment and to diminish the pressure on the natural resources, we encourage you to use
the appropriate take-back systems. Those systems will reuse or recycle most of the materials of your end life
equipment in a sound way. The crossed-out wheeled bin symbol invites you to use those systems. If you need more
information about collection, reuse and recycling systems, please contact your local or regional waste administration.
You can also contact us for more information on the environmental performance of our products.
