Introduction

DVI2USB 3.0 User Guide

1. Introduction

DVI2USB 3.0™ is Epiphan's external frame grabber uses a single-link DVI input

connection to transmit data to a video capture workstation through a USB 3.0 port.

The video capture workstation can capture, record and broadcast uncompressed

diagnostic-quality images and videos from a VGA and DVI sources. Both audio and

video capture is supported for HDMI sources. No peripheral component interface

(PCI) is required. This product is designed specifically for applications that require the

support of a DVI/VGA/HDMI input.

DVI2USB 3.0 captures video from any single link DVI, unencrypted HDMI, or VGA

video source. Meeting greater demands for transferring larger files at faster speeds,

this external frame grabber supports USB 3.0 technology, capable of transferring

uncompressed data with speeds of up to 5.0 (Gbits/s) - about ten times faster than

USB 2.0.

Note: In practice transfer speeds are dependent on factors such as the task and

hardware configuration.

DVI2USB 3.0 is versatile and can be used with multiple workstation configurations. It

is backward compatible with USB 2.0 connections, however it transfers compressed

video with a lower quality when using USB 2.0.

DVI2USB 3.0 supports full HD capture rate of 30 frames per second for 1080p video

and video sources with resolutions up to 1920x1200. When DVI2USB 3.0 is

configured to capture and transfer video to a third-party software, such as Windows

Media Encoder using YUV 4:2:0 color format, video can be captured and recorded up

to 60 frames per second.

For more information about increasing the frame rate when capturing, recording and

streaming video using third-party applications, refer to the How to Record Video using

Window Media Encoder tutorial on Epiphan’s website.

Physical Attributes

DVI2USB 3.0 User Guide

The DVI2USB 3.0 frame grabber is fully compatible with DirectShow in Windows,

Video4Linux in Linux, and QuickTime in Mac OS.

In addition to capturing video from DVI, VGA, HDMI (video and audio) sources,

DVI2USB 3.0 supports DisplayPort, Mini DisplayPort, and Thunderbolt sources using

a converter cable, sold separately. Resolutions of up to 1920x1200 are supported,

with a minimum capture rate of 30 frames per second.

DVI2USB 3.0 is part of Epiphan’s complete line of video and audio signal capture

products. For more information about all Epiphan’s video signal capture products,

2.2 USB 2.0 Backwards Compatibility

DVI2USB 3.0 is USB 2.0 backwards-compatible; you can connect it to the USB 2.0

port in situations when a laptop or workstation has a USB 2.0 port only. It will not

prevent you from using the frame grabber in these circumstances. DVI2USB 3.0 uses

green and blue LEDs to indicate whether it is connected to a USB 2.0 or 3.0 port.

Refer to section System Hardware Features for information on LED indicators.

Configuration Tips:

 The DVI2USB 3.0 cannot transfer uncompressed video when connected to

the workstation’s USB 2.0 port. This standard provides lower transfer speed

than the USB 3.0 standard therefore the frame grabber will compress the

captured data before transferring.

Physical Attributes

DVI2USB 3.0 User Guide

 The DVI2USB 3.0 must be connected to the USB 3.0 port on the video

capture workstation when capturing video and audio from an HDMI source,

otherwise only video is captured. For information about configuring a video

capture workstation to capture video and audio from an HDMI source, refer to

section Windows Capture Application.

2.3 Cables, Connectors and Adapters

High speed data transfer (up to 1.5 GB/s) is supported by USB 3.0 when you connect

your DVI2USB 3.0 to the USB 3.0 port on the video capture workstation.

The DVI2USB 3.0 can be connected to different types of equipment using a variety of

cables, and adapters. This section describes a subset of compatible connectors,

cables and adapters.

Whenever possible, when splitting the VGA signal, use an active VGA splitter rather

than a passive VGA splitter (also called a Yadapter). This will help maintain a cleaner

video signal.

If the capture application cannot find the frame grabber:

 Confirm that the frame grabber is connected to a video capture workstation

USB port and has power connected and the device LEDs are lit.

 Disconnect and re-connect the frame grabber. This prompts Windows to

install the device drivers for the frame grabber if they haven’t already been

installed.

 Observe the behaviour of the frame grabber LED indicators.

The Linux Epiphan USB device driver receives images from an Epiphan DVI2USB 3.0

and delivers the images to the Epiphan capture API and to Video4Linux. Before

delivering the images the Epiphan USB device driver also performs image adjustment

to improve the quality of the image. Image adjustments include setting the sampling

phase, PLL adjustments, and Horizontal shift. The USB device driver can also change

the color depth of the captured image before sending the image to the video API. For

example, if the DVI2USB 3.0 is capturing the frames at a color depth that is different

than that required by the video capture application, the USB device driver converts the

images to the required color depth.

Linux Video Capture Workstation Software

DVI2USB 3.0 User Guide

The Epiphan USB device driver may not be available for your version of Linux.

Epiphan does not provide source code for the Epiphan USB device driver. But you can

contact Epiphan if you need an Epiphan USB device driver compiled for a specific

Linux kernel version or kernel setting. Using the Epiphan software development kit

(SDK) you can also create custom USB device drivers that incorporate the functions

you need.

7.2 Video4Linux

Video4Linux (V4L) is a Linux video capture API. The Epiphan USB device driver can

send captured images directly to Video4Linux. This means that any Video4Linux-

compatible application can receive captured images. You can use a Video4Linux-

compatible application to record a series of captured images as a video in the video

format supported by the Video4Linux application. You can also create your own

custom Video4Linux-compatible video capture application to record captured images

from Video4Linux.

7.3 The Epiphan Capture API

The Epiphan capture API also receives captured images from the Epiphan USB

device driver. The Epiphan capture API is optimized for processing Epiphan DVI2USB

3.0 captured images. The Epiphan capture API analyzes individual images,

performs on-device cropping, and handles video mode changes. The Epiphan capture

API is an alternative to using Video4Linux to capture images on Linux video capture

workstations. You can use the Epiphan software development kit (SDK) to create

custom video capture application to record captured images from the Epiphan capture

API.

Connecting DVI2USB 3.0

DVI2USB 3.0 User Guide

7.4 V4L Custom Video Capture Applications

Epiphan does not provide a video capture application for Linux. However, you can use

Video4Linux-compatible applications to perform many video capture operations such

as recording images or video, copying, printing and saving images, or broadcasting

images over the Internet. You can also use the Epiphan Linux SDK to create your own

custom video capture application. The SDK along with some example applications is

available from the product’s Downloads page (http://www.epiphan.com/products/dvi-

frame-grabbers/dvi2usb-3-0/downloads/).

8 Connecting DVI2USB 3.0

This section describes how to connect a DVI/VGA/HDMI source and video capture

workstation to the DVI2USB 3.0. Ensure the Epiphan capture software is installed on

the video capture workstation before connecting the DVI2USB 3.0.

1. Connect the DVI2USB 3.0 to the video source. Perform one of the following: a) Connect a DVI source directly to the DVI IN port using a standard DVI cable. b) Connect a VGA source, use a VGA to DVI cable. c) Connect an HDMI source, use an HDMI to DVI adapter.

2. Connect the DVI2USB 3.0 to the video capture workstation. Connect the USB

AM-BM cable from the DVI2USB 3.0 to the workstation’s USB 3.0 or 2.0 port.

If you installed the drivers and application software, the video capture workstation

should automatically recognize the DVI2USB 3.0 and install drivers for it.

Note: You can use a high-quality VGA or DVI splitter to split the VGA or DVI signal

between an external monitor and the frame grabber.

13 Web Broadcasting

You can use the information in this chapter to share or broadcast the images captured

by your DVI2USB 3.0 over the Internet. Note that web broadcasting is available only

on video capture workstations running Windows.

To broadcast captured images over the Internet, the video capture application sends

captured images to an Epiphan web broadcasting portal. Each web broadcast session

is labelled with the serial number of the DVI2USB 3.0 that is capturing the images.

The card’s serial number appears on the video capture application title bar.

Web broadcasting sends the currently captured images or video only. You cannot

broadcast saved recordings and the DVI2USB 3.0 web broadcasting feature does not

include sound, even when audio and video is captured for HDMI sources.

Note: The web broadcasting feature included with the Epiphan video capture

application is intended as a demonstration only and has a 10-hour time limit.

Web Broadcasting

DVI2USB 3.0 User Guide

It is important to note that the images broadcasted over the Internet are not secure.

Potentially anyone can view the web broadcast if they know the correct URL. The web

broadcasting feature included with the Epiphan video capture application is a relatively

limited. Epiphan’s broadcasting products provide a richer web broadcasting feature

set.

13.1 To set the display format for web broadcasting

1. Open the DVI2USB 3.0 capture tool application on a video capture

workstation running Windows.

2. From the Tools menu select Options.

3. Select the Display tab.

4. Set Display Format to RGB 24 bits per pixel.

5. Optionally limit the frame rate to reduce the number of images sent over the

Internet reducing the amount of bandwidth being used. Depending on your

requirements you may not have to change any other display settings. Refer

to section, Configuring Display Options for all available display settings.

6. Select OK to save your changes.

13.2 Starting a web broadcasting session

No special setup is required for web broadcasting except that the video capture

workstation must be able to connect to the Internet. The video capture workstation can

be connected directly to the Internet or to a LAN that is connected to the Internet.

Before broadcasting captured images over the Internet you need to set the display

format to 24 bits per pixel. Please refer to the previous section, To set the display

format for web broadcasting.

To start a web broadcast:

1. Connect the Epiphan frame grabber to the video source that you want to

broadcast and to the video capture workstation.

13.3 Viewing a web broadcasting session

You can view a web broadcasting session from a web browser running under

Windows 2000, XP, Vista and 7 versions. The following browsers are now supported:

Internet Explorer, Firefox, Opera, Chrome, Safari. Mobile browsers are also supported

if the mobile device is compatible with Java SE. The workstation and web browser

should be running the most recent version of the Java plug-in. You can download the

latest plugin from http://www.java.com.

Web Broadcasting

DVI2USB 3.0 User Guide

To view a web broadcast:

1. Open a web browser and browse to the required URL, for example:

http://www.vga2web.com/D2P00000. This URL is supplied by the vg2web

application and can be advertised to potential viewers of the broadcast.

A second web browser window appears displaying the message Applet is

loading. Please wait… The broadcasted image should appear within 10 to 20

seconds.

The first web browser window in which the web broadcast URL address was

entered, displays a message indicating that the web presentation has been

opened in a new window. You can also use the first window to refresh the

broadcast or re-open the broadcast window if it is accidentally closed.

13.4

Changing web broadcasting compression and

performance

Normally you should not need to change the default web broadcasting compression

settings. The default settings reduce the amount of Internet bandwidth used for web

broadcasting by applying a combination of lossless and lossy compression to the

images being broadcasted.

To change the web broadcasting compression, from the Tools menu of the DVI2USB

3.0 capture tool select Options and then select Sharing. Select Override default

compression settings and adjust the Lossless and Lossy settings.

13.5 Troubleshooting web broadcasting performance

Here are three typical reasons for adjusting web broadcasting compression:

Advanced Topics

DVI2USB 3.0 User Guide

 If you have a slow Internet connection or if viewers of the web broadcasts

notice delays you can increase lossless or lossy compression to reduce

Internet bandwidth usage.

 If viewers of the web broadcast notice poor image quality you can reduce the

amount of lossy compression.

 If the video capture workstation CPU usage is too high during web

broadcasts or if viewers of the web broadcasts notice delays and you have

determined that the delays are not caused by low Internet bandwidth. The

delays could be caused by high CPU usage on the video capture workstation

resulting in the video capture workstation not being able to process all image

data. Lossless compression increases CPU usage, so you can reduce CPU

usage during web broadcasting by reducing lossless compression.

Note: You cannot change web broadcasting compression during a web broadcast.

You must stop the broadcast, adjust the settings and then start the broadcast again.

Changes made to default web broadcast compression settings are only visible to

viewers of the web broadcast. Changing these settings does not change how the

video capture application displays, records, or prints captured images.

14.1 EDID

14.1.1 About EDID

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 and, therefore, to

Advanced Topics

DVI2USB 3.0 User Guide

determine the resolution, color depth and other settings that the monitor will accept.

EDID is defined by a standard published by the Video Electronics Standards

Association (VESA). The EDID includes manufacturer name, product type, phosphor

or filter type, timings supported by the display device, display size, luminance data and

(for digital displays only) pixel mapping data. EDID is crucial for DVI sources but

mostly ignored by VGA sources.

When you connect a DVI2USB 3.0 to a video source, the video source sees the

DVI2USB 3.0 as a monitor. Just like a monitor, the DVI2USB 3.0 contains EDID that is

used by the video source to determine the video signal to send to the DVI2USB 3.0.

Usually you would operate a DVI2USB 3.0using the factory installed default EDID.

However, in some cases when you connect a DVI2USB 3.0 to a video source, the

video source may operate using video settings that you do not want it to operate at.

For instance, you can control the video source output settings by uploading a custom

EDID file to the DVI2USB 3.0. The EDID information in the file restricts the video

signal that can be accepted by the DVI2USB 3.0. For example, you can upload a

custom EDID file to your DVI2USB 3.0that reports that the DVI2USB 3.0only operates

at 1040x768. When the video source reads the EDID from the DVI2USB 3.0, the video

source will reset to operate at 1024x768 as set in the EDID.

You can obtain custom EDID files from Epiphan Support. You can also download

custom EDID files for DVI2USB 3.0 frame grabber from the frame grabber product

page of the Epiphan web site. This page contains custom EDIDs for single video

resolutions (for example, 640x480 only, 800x600 only, and 1024x768 only) for each

DVI2USB 3.0. This page also contains default EDIDs for each DVI2USB 3.0. You can

use the custom EDIDs to restrict the video resolution of the video source connected to

the DVI2USB 3.0. You can use the default EDIDs to return your DVI2USB 3.0 to

normal operation.

Advanced Topics

DVI2USB 3.0 User Guide

14.1.2 Changing the EDID on your frame grabber

Use the following steps to upload a new EDID to your DVI2USB 3.0. The uploaded

EDID is permanently installed in the DVI2USB 3.0 and the DVI2USB 3.0 will always

share this EDID with the video source.

1. Download an EDID file from the Epiphan web site or obtain an EDID file from

Epiphan Support.

2. Disconnect the DVI cable from the DVI2USB 3.0. Keep the DVI2USB 3.0

connected to the video capture workstation USB port.

3. From the video capture application Tools menu, select Upload EDID and select

the EDID file.

4. Wait for the EDID update to complete. This can take several minutes.

5. Reconnect the DVI cable to the DVI2USB 3.0.

6. Set the required resolution on the video source. You may need to disable/re-

enable or reset the DVI port.

14.1.3 An EDID example

In this example, a user was viewing the video output from a system using a flat panel

monitor. The monitor displayed video images at a screen resolution of 640x480. When

the user replaced the flat panel monitor with a DVI2USB 3.0, the system changed to

produce video images at a screen resolution of 720x400.

It turned out that the video source preferred to output 720x400, but because the

original monitor did not support 720x400, the video source was forced to operate at

640x480. The DVI2USB 3.0 supported 720x400 so the system changed to this

resolution when the DVI2USB 3.0 was connected to it.

The user wanted to return the video source to operating at 640x480 but could not

manually adjust the screen resolution. To solve the problem, Epiphan created a

custom EDID for the DVI2USB 3.0 that excluded support for 720x400. When the user
