DVI2PCIe Duo Introduction

DVI2PCIe Duo User Guide

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.

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.

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.

Linux Video Capture Workstation Software

DVI2PCIe Duo User Guide

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 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.

Each suffix starts with a % sign and can include

the following characters:

02, 04, 06, or 08 indicates the number of digits to

use in numbering the suffix. You can specify 2, 4,

6, or 8 digits.

“d” means decimal numbers are used in the

suffix.

“X” means hexadecimal numbers are used in the

suffix.

The suffix %02d means the saved file names end

with two-digit decimal numbers, for example: 01,

02, 03, ..., 10, 11 and so on. The suffix %04X

means the saved file names end with 4-digit

hexadecimal numbers, for example: 0001, 0002,

0003, ..., 000A, 000B and so on.

13 Web Broadcasting

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

Web Broadcasting

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. 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 bandwidth. 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 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

Web Broadcasting

DVI2PCIe Duo User Guide

The Start web broadcasting dialog box appears.

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.

DVI2PCIe Duo User Guide

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 re-

open 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.

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.

Advanced Topics

DVI2PCIe Duo User Guide

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.

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

Epiphan Support.

Advanced Topics

DVI2PCIe Duo User Guide

2. Disconnect any input cables from the DVI2PCIe Duo. Keep the DVI2PCIe Duo

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 input cables to the DVI2PCIe Duo.

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

enable or reset the DVI or SDI input 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 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

command line options with spaces.
