DVI2PCIe Duo Introduction
1. DVI2PCIe Duo Introduction
DVI2PCIe Duo™ is Epiphan's newest internal frame grabber with a DVI-I dual link and
an SDI input . It is installed in a video capture workstation’s PCI Express (PCIe) slot
and transmits captured data to the video capture workstation over the PCIe bus.
DVI2PCIe Duo captures video from any dual or single link DVI, unencrypted HDMI,
VGA, or 3G-SDI, HD-SDI and SD-SDI source. An optional A/V kit can be installed to
capture S-Video/composite, analog audio and balanced or unbalanced TRS audio.
DVI2PCIe Duo captures full HD at 60 frames per second and captures and streams
audio and HD video sources with resolutions up to 2048×2048 when connected to a
DVI-I dual link connector. The DVI2PCIe Duo capture card driver is fully compatible
with DirectShow in Windows, Video4Linux in Linux, and QuickTime in Mac OS X, and
can be used with third party software.
In addition to capturing video from SDI, DVI/HDMI/VGA and S-Video/composite video
sources, DVI2PCIe Duo supports DisplayPort, Mini DisplayPort, and Thunderbolt
sources using a converter cable, sold separately.
DVI2PCIe Duo is part of Epiphan’s complete line of video signal capture products.
For more information about all of Epiphan’s video signal capture products, please

Physical Attributes
2 Physical Attributes
2.1 System Hardware Features
The Epiphan DVI2PCIe Duo frame grabber is a PCIe x4 card that includes a DVI-I
type connector, SDI connector and three activity LEDs. The DVI2PCIe card can be
installed in a 4x, 8x or 16x PCIe slot on the motherboard of the video capture
workstation.
Note: To maintain high performance levels, the DVI2PCIe Duo card requires a
minimum of PCIe x4. Consult your motherboard manufacturer’s support to ensure
your motherboard supports PCIe x4.
Note: PCIe card performance is determined by the length of the card and slot, (x1, x4,
x8 or x16) and the generation of the PCIe card and the motherboard slot. The
DVI2PCIe Duo card is a generation 2 card and is fully backward compatible with first
generation slots; the card will perform at first generation speed. DVI2PCIe Duo card is
compatible with generation 3 slots; the card will perform at generation 2 speed.

Figure 3: PCIe slots (from top to bottom: 4x, 16x, 1x and 16x), compared to a traditional 32bit PCI slot (bottom)
When installed, the DVI2PCIe Duo card adds a DVI IN and an SDI IN port and an LED
indicator. You can connect a DVI-I (single link/dual link) source directly to the DVI IN
port using a standard DVI cable. You can connect an SDI source (3G-SDI, HD-SDI
and SD-SDI) directly to the SDI IN port using an SDI cable with a BNC connector. To
connect a VGA source, use a VGA to DVI cable. To connect an HDMI source, use an
HDMI to DVI adapter.

Linux Video Capture Workstation Software
Epiphan provides the Epiphan USB device driver and the Epiphan capture API for
Linux. Epiphan does not provide a video capture tool for Linux. However, the USB
device driver is compatible with Video4Linux so you can use Video4Linux compatible
applications to receive and process captured images. You can also use the Epiphan
Linux SDK to write your own custom video capture application that receives captured
images from the Epiphan capture API. The following software components operate on
a video capture workstation running Linux:

The Epiphan USB device driver

Video4Linux

The Epiphan capture API

V4L custom video capture applications
7.1 The Epiphan USB Device Driver
The Linux Epiphan USB device driver receives images from an Epiphan DVI2PCIe
Duo 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 DVI2PCIe Duo 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.
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.
24
DVI2PCIe Duo User Guide
Linux Video Capture Workstation Software
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 Video4Linuxcompatible application can receive captured images. You can use a Video4Linuxcompatible 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 receives captured images from the Epiphan USB device
driver. It is optimized for processing Epiphan DVI2PCIe Duo captured images. The
Epiphan Capture API analyzes individual images, performs on-device cropping, and
handles video mode changes. It 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 your own custom video capture application to record
captured images from the Epiphan Capture API.
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 across 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 downloads page of the Epiphan Web Site. To
download the latest version, browse to http://www.epiphan.com/products and
locate the downloads page for your product.

Use the information in this chapter to share or stream the images captured by your
DVI2PCIe Duo over the Internet. Note that web streaming is available on video
capture workstations running Windows.
To stream captured images over the Internet, the Epiphan capture tool sends captured
images to an Epiphan web streaming portal. Each web streaming session is labelled
with the serial number of the DVI2PCIe Duo that is capturing the images. The card’s
serial number appears on the video capture application title bar.
Web streaming sends the currently captured image only. You cannot broadcast saved
recordings and the DVI2PCIe Duo web streaming feature does not include sound.
Note: Web streaming using Epiphan Capture Tool is intended as a demonstration
only and has a 10-hour time limit.
It is important to note that images streamed over the Internet are not secure.
Potentially anyone can view the stream if they know the URL. Web streaming
71
DVI2PCIe Duo User Guide

supported by the Epiphan Capture Tool is a relatively limited feature. Epiphan’s
streaming products provide a richer web streaming feature set.
13.1 To set the display format for web streaming
1.
Open the capture tool on a video capture workstation running Windows.
2.
From the Tools menu select Options.
3.
Select the Display tab.
4.

Display Options for all available display settings.
6.
Select OK to save your changes.
13.2 To start a web streaming session
No special setup is required for web streaming except 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 streaming 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 streaming.
To start a web broadcast:
1.
Connect the Epiphan Frame Grabber to the video source that you want to
stream and to the video capture workstation.
2.
Start the Epiphan Capture Tool.
3.
Select Web Broadcasting from the Tools menu or from the toolbar select
.

Figure 38: Start Web Broadcasting Dialog
13.3 Viewing a web broadcasting session
View a web broadcasting session from a web browser running Windows 2000, XP,
Vista and 7 versions. The following browsers are supported:

Internet Explorer

Firefox

Opera

Chrome

Safari
Mobile browsers are also supported if the mobile device is compatible with Java SE.
The video capture workstation and web browser should be running the most recent
version of the Java plug-in. Download the plug-in’s latest version from
http://www.java.com.
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 vga2web
application as shown on the Figure 38: Start Web Broadcasting Dialog and
can be advertised to potential viewers of the stream.

A second web browser window appears displaying the message Applet is
loading. Please wait… The streamed image should appear within 10 to 20
seconds.
The first web browser window in which the web stream URL address was
entered, displays a message indicating that the web presentation has been
opened in a new window. Use the first window to refresh the stream or reopen the stream window if it is accidentally closed.
13.4 Changing web streaming compression and
performance
Normally you should not need to change the default web streaming compression
settings. The default settings reduce the amount of Internet bandwidth used for web
streaming by applying a combination of lossless and lossy compression to the images
being broadcasted.
To change the web streaming compression, from the Tools menu of the DVI2PCIe
Duo capture tool select Options and then select Sharing. Select Override default
compression settings and adjust the Lossless and Lossy settings.
13.5 Troubleshooting web streaming performance
The following are three typical reasons for adjusting web streaming compression:

If you have a slow Internet connection or when viewers of the web stream
notice delays, you can increase lossless or lossy compression to reduce
Internet bandwidth usage.

If viewers of the web stream notice poor image quality you can reduce the
amount of lossy compression.
74
DVI2PCIe Duo User Guide

If the video capture workstation CPU usage is too high during web streaming
or if viewers of the web stream 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 streaming by reducing lossless compression.
Note: You cannot change web streaming compression during a web broadcast. You
must stop the stream, adjust the settings and then start the stream again.
Changes made to default web stream compression settings are only visible to viewers
of the web stream. Changing these settings does not change how the video capture
application displays, records, or prints captured images.
14 Advanced Topics
14.1 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
determine the resolution, color depth and other settings that the monitor will accept.
14.1.1
About EDID
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.
75
DVI2PCIe Duo User Guide
Advanced Topics
When you connect a DVI2PCIe Duo to a video source, the video source sees the
DVI2PCIe Duo as a monitor. Just like a monitor, the DVI2PCIe Duo contains EDID
that is used by the video source to determine the video signal to send to the DVI2PCIe
Duo.
Usually you would operate a DVI2PCIe Duo using the factory installed default EDID.
However, in some cases when you connect a DVI2PCIe Duo to a video source, the
video source may operate using video settings at which you do not want to operate.
For instance, you can control the video source output settings by uploading a custom
EDID file to the DVI2PCIe Duo. The EDID information in the file restricts the video
signal that can be accepted by the DVI2PCIe Duo. For example, you can upload a
custom EDID file to your DVI2PCIe Duo that limits the DVI2PCIe Duo to operate at
1040x768. When the video source reads the EDID from the DVI2PCIe Duo, 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 DVI2PCIe Duo 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
DVI2PCIe Duo. This page also contains default EDIDs for each DVI2PCIe Duo. You
can use the custom EDIDs to restrict the video resolution of the video source
connected to the DVI2PCIe Duo. You can use the default EDIDs to return your
DVI2PCIe Duo to normal operation.
14.1.2
Changing the EDID on your Frame Grabber
Use the following steps to upload a new EDID to your DVI2PCIe Duo. The uploaded
EDID is permanently installed in the DVI2PCIe Duo and the DVI2PCIe Duo will always
share this EDID with the video source.

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 DVI2PCIe Duo, 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 DVI2PCIe Duo supported 720x400 so the system changed to this
resolution when the DVI2PCIe Duo 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 DVI2PCIe Duo that excluded support for 720x400. When the
user uploaded the custom EDID to the DVI2PCIe Duo, the video source returned to
operating at 640x480.
14.2 Windows command line options
Use the following command line options to control how the Windows video capture
application starts up. You can add as many command line options as you want in any
order. All command line options must start with two dashes. Separate
