The VGA or DVI video source
The VGA or DVI video source
Image capture begins with a VESA-compatible VGA, DVI, or
dual-DVI video source. Virtually all personal computers as well
as almost any device that displays images includes a VESAcompatible VGA or DVI video connection that you can connect an
Epiphan Frame Grabber to. To capture the video images from a
VGA or DVI source you connect the video source directly to a
suitable Epiphan Frame Grabber using a suitable cable.
Figure 4: Video source (VGA, DVI, or dual-DVI output)

Grabber.
For example, if your video source is VESA-compatible VGA
source and if you want to capture images with a resolution of up
to 1600 x 1200 at a frame rate of 30 frames a second then you
could choose a VGA2USB HR or VGA2USB Pro. Both of these
Frame Grabbers ship with the VGA video cable and adapters that
you need to connect the video source directly to your Frame
Grabber.

The Frame Grabber
How Epiphan Frame Grabbers operate
The Frame Grabber is a hardware device that captures images
(also called frames) from analog VGA signals or digital DVI
streams. Capturing images means reading data from the VGA or
DVI signal and converting this data into a digital image.
The Frame Grabber synchronizes itself with the video source to
capture images at the resolution and color depth output by the
video source or at the maximum color depth and resolution
supported by the Frame Grabber. The Frame Grabber captures
images at its own frame rate up to the maximum frame rate
capacity of the Frame Grabber.
Epiphan Frame Grabbers perform the following functions to
optimize and compress captured image data. The aim is to reduce
the amount of data required for each captured image and
optimize data transmission to the video capture workstation.
These functions include:
• Pre-compression using technology developed by Epiphan to
clean up and optimize the image. Pre-compression reduces the
amount of data required for each image and improves the
performance of the standard compression algorithms also
built into most Epiphan Frame Grabbers. See Pre-compression
of computer-generated images on the Epiphan Web Site for a
description of pre-compression.
• Lossless image compression using industry standard image
compression algorithms.
• Optional on-board cropping of the image.
• Color space conversion.
• USB transfer acceleration.
The result is the Frame Grabber captures a large amount of image
data, converts the image data to RGB format at the maximum
color depth that the Frame Grabber supports at the operating
resolution, compresses and optimizes the data and then transmits
the data to the video capture workstation.
All Epiphan Frame Grabbers use USB 1.1 and USB 2.0 to transfer
captured images to the video capture workstation. USB 2.0 is
Page 32
Epiphan Frame Grabber
11. About Epiphan frame grabbing technology
The video capture workstation
recommended especially for high resolution and high frame rate
applications because USB 2.0 supports much higher data transfer
rates than USB 1.1. The USB version used depends on the video
capture workstation.
The video capture workstation
The video capture workstation is a personal computer running a
supported operating system such as Windows (2000, XP or Vista),
Mac OS X Panther, or supported versions of Linux. For video
capture workstation system requirements see Chapter 2. “System
Requirements” on page 11.

To be a video capture workstation the PC must include a USB
device driver that can receive images from Epiphan Frame
Grabbers. The video capture workstation must also include video
capture application software for processing captured images
according to your requirements. For example, you may want the
video capture application software to display captured images or
you may also want to record and print captured images, or you
may want to share captured images by broadcasting them across
the Internet to a remote location.
An Epiphan Frame Grabber is compatible with Windows, Mac
OS X Panther or Linux PC platforms. The video capture
workstation components are similar on each of these platforms. A

notable difference is that each platform includes different image
processing application programming interfaces (APIs):
• On Windows 2000, XP, and Vista the Epiphan USB device
driver and video capture application is compatible with the
Microsoft DirectShow API.
• On Mac OS X the Epiphan USB device driver and video
capture application is compatible with the Apple QuickTime
API.
• On Linux the Epiphan USB device driver and video capture
application is compatible with the Video4Linux V4L API.
The following sections describe the video capture workstation
software components and APIs on each supported video capture
application platform.

About kernel mode and user mode
Some video capture workstation software components operate in
kernel mode and some in user mode. Kernel mode programs are
usually always running in the background and are usually not
started and stopped by users. Kernel mode programs are usually
configured from a central location such as the Windows control
panel. Most software that communicates directly with hardware
components operate in kernel mode. On all operating systems the
Epiphan USB device driver is a kernel mode application.
User mode programs are programs that users run to perform a
task such as word processing, drawing graphics, or recording
captured images. Users start, stop, use and configure user mode
programs. User mode programs do not usually communicate
directly with hardware components. They communicate with
kernel mode programs and it is the kernel mode programs that
communicate with the hardware components. The Epiphan video
capture application is a user mode program.

Windows video capture application software
The following software components operate on a video capture
workstation running Windows 2000, XP, or Vista:
• The Epiphan USB device driver
• DirectShow
• The Epiphan capture API
• The Epiphan video capture application
• Video codecs
The Epiphan USB device driver
The Windows 2000, XP and Vista Epiphan USB device driver
receives images from an Epiphan Frame Grabber and delivers the
images to the Epiphan capture API and to DirectShow. 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. See “Configuring image
adjustments” on page 136 for more information about image
adjustments.
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 Frame Grabber 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.

Frame Grabbers connected to the video capture workstation. You
can also configure image adjustments for each Frame Grabber
and configure how the Epiphan USB device driver communicates
with DirectShow. See “Configuring DirectShow options” on
page 143.
If you have successfully installed the Epiphan USB device driver,
when you connect a Frame Grabber, the name of the Frame
Grabber appears in the Windows Device Driver under Imaging
Devices. For example, if you installed a DVI2USB Solo Frame
Grabber the name of the imaging device would be “DVI2USB
Solo by Epiphan Systems Inc”.

Glossary of Terms
This glossary describes many of the terms used in this Epiphan
Frame Grabber User Guide.
Color depth, bits per pixel (bpp)
Color depth or bits per pixel (bpp) (also known as color
resolution) is a computer graphics term describing the number of
bits used to represent the color of a pixel in a bitmapped image or
video frame. Epiphan Frame Grabbers support a number of color
depths:
• RGB 24 bits per pixel, RGB 8:8:8 format: also known as true
color and millions of colors, 24-bit color is the highest color
depth normally used. 24bpp can display over 16.7 million
colors. Most video codecs require a color depth of 24 bpp.
• RGB 16 bits per pixel, RGB 5:6:5 format: also known as high
color and thousands of colors. 16 bpp may look as good as 24
bpp in many applications while using less data. However
more complex images may not look as good with a 16 bpp
color depth. 16 bpp can display over 65,536 colors.
• RGB 8 bits per pixel, RGB 3:3:2, 3:2:3, 2:3:3: uses much less data
than 16 bpp but can only display 256 colors. 8 bpp is usually
only useful for video streams with very low color depth.
User Guide
Page 45
11. About Epiphan frame grabbing technology
Glossary of Terms
• 8 bits per pixel, grayscale 256 levels: uses a similar amount of
data as RGB 8 bpp but images are black, white, and shades of
gray. Usually you would only use 8 bpp grayscale if your
video source or codec used this color depth or to reduce file
size.
• 5 bits per pixel, grayscale 32 levels: a grayscale format that has
fewer levels of gray and uses less data than grayscale 256
levels. Usually you would only use 5 bpp grayscale if your
video source or codec used this color depth or to reduce file
size.
• Black and white: a very low quality and low data format that
uses only black and white. Usually you would only use black
and white if your video source is producing a black and white
video signal.
• 16 bits per pixel, YUY2(422), UYVY: a color format used by
many video sources. Similar to RGB 16 bpp but uses
compression and other techniques to improve the video
signal. Epiphan Frame Grabbers and the video capture
application convert YUY2(422), UYVY video images to RGB,
grayscale or black and white images.
All color depths are not supported by all video codecs or image
file formats. Most video codecs and image file formats support
RGB 24 bpp. It may be difficult to find a video codec that supports
other color depths. Some image file formats do not support all
color depths. Epiphan Frame Grabber web broadcasting operates
at RGB 24 bpp.
Epiphan Frame Grabbers capture images at the color resolution of
the video source up to the maximum resolution supported by the
Frame Grabber. The maximum resolution supported by the
VGA2USB Frame Grabber is 16 bits per pixel (bpp). The
maximum supported by all other Epiphan Frame Grabbers is 24
bpp.
Capture, image capture, frame grabbing
Epiphan products can capture VGA, DVI, or dual DVI images.
Capturing VGA data involves using a Frame Grabber to digitize
analog VGA signals and transmit the digitized images as frames
over a USB connection to the Epiphan video capture application.
Page 46
Epiphan Frame Grabber
11. About Epiphan frame grabbing technology
Glossary of Terms
Capturing DVI or dual DVI data involves using a Frame Grabber
to convert DVI or dual DVI data into frames that can be
transmitted over a USB connection to the Epiphan video capture
application.
Capturing can also compress images before they are transmitted.
Frames must be captured before they are displayed, printed, or
recorded by the Epiphan video capture application.
Color resolution
See “Color depth, bits per pixel (bpp)” on page 45.
DVI
Digital Visual Interface (DVI) is a digital standard for
transmitting visual data from a graphics source (such as a PC
video card) to a display device (such as a computer monitor).
Many devices that output digital visual images use the DVI
standard for transmitting visual data. All Epiphan DVI2USB
Frame Grabbers capture digital DVI frames and convert them to
digital signals that are transmitted to the Epiphan video capture
application using a USB connection. This USB data is then
interpreted and displayed using the Epiphan video capture
application.
Frame Grabber
A hardware device that captures frames from analog VGA signals
or digital DVI streams. Epiphan Frame Grabbers may modify
captured frames and compress them before sending them to a
video capture workstation over a USB connection.
Frame
A frame is one of the many still images which can be combined to
create a moving picture such as a video image. The term frame
comes from the film industry. Film images are recorded on a strip
of photographic film and each image looks like a framed picture.
User Guide
Page 47
11. About Epiphan frame grabbing technology
Glossary of Terms
Record
The process of saving (or recording) captured frames as video
files or as sets of image files. Recording requires that frames are
first captured before being recorded.
VGA
Video Graphics Array (VGA) is an analog standard for
transmitting visual data from a graphics source (such as a PC
video card) to a display device (such as a computer monitor).
VGA originated in 1988. Most PCs and many other devices that
output analog visual images use the VGA standard or extensions
to the VGA standard for transmitting visual data. All Epiphan
VGA2USB Frame Grabbers capture analog VGA frames and
convert them to digital signals that are transmitted to the Epiphan
video capture application using a USB connection. This USB data
is then interpreted and displayed using the Epiphan video
capture application.
VGA modes
A VGA mode describes the timing of the VGA signals sent by a
VGA source to a VGA display device (or Frame Grabber). The
VGA source and receiver (for example a monitor) must agree on
the VGA mode so that the VGA display device can decode the
timing of the VGA signal and display images.
A VGA signal consists of a series of frames. Each frame is a single
image displayed by a VGA display device or captured by a Frame
Grabber. A VGA frame is made up of horizontal lines. Each line is
made up of pixels. The pixels in each line are transmitted from
left to right. The lines in each frame are transmitted from top to
bottom. If the VGA signal is interlaced each frame consists of
every other line of the frame. An interlaced signal contains less
data and so displays faster but also results in a lower quality
image.
The timings in a VGA mode start with the refresh rate; which
defines how often a new frame is sent. A VGA mode also
indicates if the signal is interlaced.
Page 48
Epiphan Frame Grabber
11. About Epiphan frame grabbing technology
Glossary of Terms
Next a VGA mode describes the timing of the horizontal signals.
These horizontal timings define how the data that makes up each
line is transmitted. The line begins with the active area, which
contains the RGB values for each pixel in the line. The active area
is followed by a blanking region that contains black pixels. Inside
the blanking interval, a horizontal sync pulse is transmitted to
keep the signals synchronized. The blanking interval before the
sync pulse is called the front porch, and the blanking interval after
the sync pulse is called the back porch. The time between
horizontal sync pulses is called the sync time. The sync polarity
designates whether the sync pulse is positive or negative.
The vertical timings work the same way to define how the data
that makes up each frame is transmitted. A frame begins with the
active video area that contains all of the lines in the frame. The
vertical signal also includes a vertical synch pulse that is timed
according to the vertical sync time. The vertical blanking intervals
are also called the front porch and back porch. Finally the vertical
synch polarity designates whether the vertical sync pulse is
positive or negative.
Video capture application
The Epiphan software that intercepts the frames (images) sent by
the Frame Grabber over the USB connection. Using the video
capture application you can display, print and record captured
frames. You can also use the video capture application to transmit
captured frames over the Internet.
Video capture workstation
A computer running Windows, Mac OS X or Linux that you can
use to record captured frames. You connect your Frame Grabber
to the video capture workstation with a USB connection. You
must also install the Epiphan video capture application on the
video capture workstation. If the video capture workstation can
connect to the Internet you can use the video capture application
to broadcast captured images over the Internet.

For example, a VGA2USB LR or PRO can capture up
to 60 frames a second (fps). This frame rate may
approach 100% CPU usage, even on a dual CPU
video capture workstation. To reduce load on the

About setting the display format
For best results you would usually set the display format color
depth to match the video source color depth. If the display format
and video source color depth do not match, the device driver or
video capture application converts the color resolution of images
as they are captured. This conversion can put extra demands on
the video capture workstation CPU.
Note: For a definition of color depth, see “Color depth, bits per
pixel (bpp)” on page 45.
In some cases; however, you may want to set the display format
to a different color depth than the video source. There are a
number of possible reasons for doing this. For example:
• You are recording captured images to video and your video
codec is not compatible with the color depth of the video
source. In this case you could set the display format to match
the requirements of your video codec.
• You want to save disk space. Setting display format to a lower
color depth reduces the size of recorded image files or videos.
Using a lower display format color depth means that the video
and image files saved by the video capture application are
smaller and use less disk space.
Page 74
Epiphan Frame Grabber
12. Windows video capture application
Recording, display, KVM and sharing options
• You have special requirements for a color depth that is
different from the color depth produced by the video source.
Set the display format to the color depth that you require.
Epiphan Frame Grabbers capture images at the color depth of the
video source up to the maximum color depth supported by the
Frame Grabber. The maximum color depth supported by the
VGA2USB Frame Grabber is 16 bits per pixel (bpp). The
maximum color depth supported by all other Epiphan Frame
Grabbers is 24 bpp.
Increasing the color depth of captured images
The VGA2USB Frame Grabber captures images at 16 bpp. If
16 bpp is supported by the codec or image file format that you are
using, you should also set the display format to RGB 16 bits per
pixel. Setting the display format to RGB 24 bits per pixel requires
the Frame Grabber device driver to convert the image format
from RGB 16 to RGB 24. This results in extra CPU and memory
usage and larger image or video files but the image quality (or
amount of information) is still the same as in the original RGB 16
images that came from the Frame Grabber.
However, in most cases even with a VGA2USB Frame Grabber
you would usually operate at 24 bpp because this color depth is
required by most video codecs and also for web broadcasting.
In most cases image capture and recording performance should
be acceptable if the video capture workstation meets or exceeds
the hardware requirements described in “Hardware
Requirements” on page 11 and if there are not a lot of concurrent
demands on this PC.
Reducing the color depth of captured images
All DVI2USB Frame Grabbers and the VGA2USB LR/HR/PRO
Frame Grabbers can capture images at RGB 24 bpp. If your video
source is operating at RGB 24 bpp and you set the display format
lower than RGB 24 bpp, you are reducing the quality of the
captured image. You are also causing the Epiphan USB device
driver to consume extra CPU and memory resources to convert
the images to the reduced color depth.

However, in some cases you may choose to reduce the quality of
the captured image for a number of reasons such as reducing file
size, or a custom application that uses a different color depth.
In most cases image capture and recording performance should
be acceptable if the video capture workstation meets or exceeds
the hardware requirements described in “Hardware
Requirements” on page 11 and if there are not a lot of concurrent
demands on this PC.
Converting color images to grayscale or black and white
If the Frame Grabber is capturing color RGB images and you set
the display format to a grayscale or black and white format, the
video capture application converts the color images to the
requested grayscale or black and white format. Conversion from
color to grayscale or black and white causes the greatest demand
on the video capture workstation CPU because the conversion is
performed by the video capture application. If you are capturing
color images, you should only set the display format to grayscale
or black and white if you have a specific need for this color depth.
If you have concerns about performance, you can make some trial
recordings to ensure the video capture workstation has sufficient
CPU and memory resources.
Windows Epiphan USB device driver
On Windows video capture workstations the Epiphan USB device
driver installs a VGA2USB control panel application (Figure 17).
You can use this control panel application to view the status of
the Frame Grabber or Frame Grabbers connected to the video
capture workstation. You can also select Configure Device to
configure the following settings for each Frame Grabber that you
have connected to the video capture workstation:
• Image adjustments, see “Configuring image adjustments” on
page 136
• How the Epiphan USB device driver communicates with
DirectShow, see “Configuring DirectShow options” on
page 143
Page 76

• Customize or limit the VGA modes that the Frame Grabber
can use, see “Configuring VGA modes” on page 145.
Figure 17:Epiphan USB device driver
Note: Changing these settings from this control panel has the
same effect as selecting Configure Device from the Capture menu
and changing the settings there.
Note: You can change and save configuration settings for any
Frame Grabber that you have connected to the video capture
workstation even if the Frame Grabber is not operating or
connected at the time. If you change the configuration of a Frame
Grabber that is not connected, the configuration is stored on the
video capture workstation and applied to the Frame Grabber
when the Frame Grabber is connected and operating.
You can also select Default Configuration to reset a Frame
Grabber to its default configuration. Editing image adjustments
and DirectShow options from the control panel application or
from the video capture application has the same results.

Selecting a Windows video codec
The video capture application automatically finds all of the video
codecs installed on the video capture workstation. Unless you
have already installed a high-speed codec, most of the codecs that
the video capture application finds may be too slow or have poor
compression. If a codec is too slow, the video recording frame rate
may be too low to produce a good quality video without
compromising the performance of the video capture workstation.
If a video codec has poor compression, the recorded *.avi files
could become very large.

Append suffix When you start a video recording session you
are prompted to enter a file name. If the file
exceeds the AVI file size limit, the video capture
application starts another file named with the
original file name appended with a sequential
numeric suffix. Use the append suffix options to
specify format of this suffix.
Each suffix starts with a % 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 use decimal numbers in the suffix.
• X means use hexadecimal numbers in the
suffix.
The suffix %02d means the saved file names
would end with two-digit decimal numbers, for
example: 01, 02, 03, ... 10, 11 and so on. The
suffix %04X means the saved file names would
end with 4-digit hexadecimal numbers, for
example: 0001, 0002, 0003, ... 000A, 000B...
starting with Enter the starting number used in the file name
suffixes in decimal format. If the suffixes
include hexadecimal numbering this decimal
number is automatically converted to
hexadecimal.
For example, if you named the video file VID,
set the suffix to %02d and set starting with to 1,
the video file names would be VID.avi,
VID01.avi, VID02.avi and so on.

Overwrite
If you select overwrite existing files the video
existing files capture application saves files according to the
video file recording options, overwriting
existing files if any are present.
If you do not select overwrite existing files,
every time the video capture application
encounters a file with the same name as it
would have used to save the file it selects the
next file name in the sequence until it can save a
file without overwriting an already saved file.
Recording a video
Before recording captured images as a video you should:
• Set the display format to RGB 24 bits per pixel (see “Setting
display options for recording videos” on page 98)
• Install and configure a video codec (see “Selecting a Windows
video codec” on page 98 and “Installing the ffvfw video codec
pack” on page 100)
• Configure video file recording options (see “Configuring
video file recording options” on page 102
• Review video recording options (see “Configuring video file
recording options” on page 102).
To record captured images as a video file
1 Connect the Epiphan Frame Grabber to the video source that
you want to record from and to the video capture workstation.
2 On the video capture workstation, start the video capture
application.
3 Make sure the video capture application is displaying the
captured images that you want to record.
4 Select Start Recording from the Capture menu or from the
toolbar select

5 Enter the file name, select the location for saving the video file,
and select Save.
As images are captured by the Frame Grabber they are
recorded to the video file. The Status bar shows the name and
location of the video file. The status bar also displays the
amount of time that the video has been recording and the
number of frames (or images) recorded.
When the size of the video file reaches the AVI file size limit,
(see “AVI file size limit” on page 103) the video capture
application does one of the following:
• stops recording.
• starts a new video file and continues recording.
(“Configuring video file recording options” on page 102
describes how to specify the file name.)
• overwrites the original video file and continues recording.
You can pause recording by selecting Pause from the Capture
menu or
from the toolbar.
You can stop recording by selecting Stop Recording from the
Capture menu or
from the toolbar. When you stop
recording the Status bar shows the name and location of the
saved video file, the amount of time that the video file was
recording, and the number of frames (or images) recorded. For
example: Wrote c:\temp\example.avi (85 sec, 464 frames).
Playing back a video file
Depending on the video codec that you used, you should be able
to play back most recorded videos using Windows Media Player.
If you are playing back the video file on a computer other than the
video capture workstation, you may need to install a video codec
on that computer.
You cannot use the Epiphan video capture application to play
back video files.

Using a DirectShow application to
record video files
This section describes how to use the VirtualDub freeware
application to capture images from an Epiphan Frame Grabber
and record the captured images as *.avi video files. You can
download and install VirtualDub from
http://www.virtualdub.org/.
This is not a detailed description of how to use VirtualDub. This
section provides a basic example of how to use a DirectShowcompatible application to capture images using an Epiphan
Frame Grabber. Even though these instructions are specific to
Virtual Dub, you can apply them to any third-party video capture
application that can get images from DirectShow. For more
information about DirectShow, see “DirectShow” on page 37.
Epiphan Frame Grabbers communicate with VirtualDub using
the DirectShow API. Any DirectShow-compatible image capture
application installed on a video capture workstation that is
connected to an Epiphan Frame Grabber can also receive
captured images from the Frame Grabber.
The key to capturing images from an Epiphan Frame Grabber
using a DirectShow-compatible capture application is to find the
Frame Grabber from the capture application. To be able to find
the Frame Grabber, you must install the Epiphan USB device
driver on the video capture workstation and connect the Frame
Grabber to the video capture workstation.
User Guide
Page 107
15. Recording videos
Using a DirectShow application to record video files
If you have successfully installed the Epiphan USB device driver,
when you connect an Epiphan Frame Grabber, the Frame
Grabber’s name appears in the Windows Device Driver under
Imaging Devices. For example, if you installed a DVI2USB Solo
Frame Grabber, the name of the imaging device would be
“DVI2USB Solo by Epiphan Systems Inc”.
You can also find the Frame Grabber from the Windows Control
Panel by opening the Scanners and Cameras control panel
application. The Frame Grabber has the same name in the
Scanners and Cameras control panel application is in the
Windows Device Driver.
From the Scanners and Cameras control panel application, you
can right-click on the Epiphan Frame Grabber icon and select Get
Pictures to save images captured by the Frame Grabber.
Before you start recording images with
VirtualDub
You must have the following components before starting to
record images using VirtualDub:
• An Epiphan Frame Grabber.
• A VGA, DVI, or Dual-DVI video source.
• A video capture workstation running Windows 2000, XP, or
Vista. See Chapter 2. “System Requirements” on page 11 for
video capture workstation system requirements.
Use the following steps to download and install the required
software and make the required connections before starting to
record captured images using VirtualDub.
1 Follow the steps in Chapter 3. “Installing the Windows
VGA2USB/DVI2USB drivers and application” on page 12 to
download and install the Epiphan USB device driver.
Unless you have developed your own USB device driver for
Epiphan Frame Grabbers, you must install the Epiphan USB
device driver, which is part of the VGA2USB/DVI2USB
drivers and application. Windows and DirectShow can then
get images from the Epiphan Frame Grabber.

You can use the information in this chapter to share or broadcast
the images captured by your Epiphan Frame Grabber over the
Internet. 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 Epiphan Frame Grabber that is
capturing the images. The Frame Grabber serial number appears
on the video capture application title bar.
Web broadcasting sends the currently captured image only. You
cannot broadcast saved recordings and Epiphan Frame Grabber
web broadcasting does not include sound.
Note: The Web Broadcasting feature included with the Epiphan
video capture application is intended as a demonstration only
and has a 5-minute time limit. You can contact Epiphan at
[email protected] to permanently enable the web broadcasting
account for your Frame Grabber. This change is made on the
Epiphan web broadcasting server and the change is not visible to
the user.
Caution: The images broadcast over the Internet are not secure.
Potentially anyone can view the web broadcast if they know the
correct Internet address. The web broadcasting supported by the
video capture application is a relatively limited feature. The

Changing web broadcasting
compression and performance
Normally you would not need to change the default web

the amount of Internet bandwidth used for web broadcasting by
applying a combination of lossless and lossy compression to the
images being broadcast.
To change web broadcasting compression, from the Tools menu
select Options and then select Sharing (Figure 32 on page 126).
Select Override default compression settings and adjust the
Lossless and Lossy settings.
User Guide
Page 125
16. Web Broadcasting
Changing web broadcasting compression and performance
Figure 32:Web broadcasting compression options
Lossless
Lossless compression compresses the images
compression being broadcast without reducing image
quality. Increasing lossless compression can use
a considerable amount of the video capture
workstation CPU resources.
The default lossless setting is 5. The range is 1
(Speed, the lowest lossless compression) to 9
(Compression, the highest lossless
compression).
Lossy
Lossy compression compresses the images
compression being broadcast by reducing image quality.
Lossy compression is not as CPU intensive as
lossless compression.
The default lossy setting is 75. The range is 10
(Compression, the highest lossy compression
and lowest quality) to 100 (Quality, the lowest
lossy compression and the highest quality).
Page 126
Epiphan Frame Grabber
16. Web Broadcasting
Changing web broadcasting compression and performance
Troubleshooting web broadcasting performance
Here are three typical reasons for adjusting web broadcasting
compression:
• If you have a slow Internet connection or if receivers of the
web broadcasts notice delays you can increase lossless or lossy
compression to reduce Internet bandwidth usage.
• If receivers 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 receivers 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.
Some examples
Here are some examples of adjusting lossless and lossy
compression for different Internet bandwidth and video capture
workstation conditions.
• If the video capture workstation has a quad-core 3GHz CPU
but connects to the Internet with a dial-up modem, you could
move the lossless slider closer to Compression to increase the
lossless compression to reduce Internet bandwidth usage.
User Guide
Page 127
16. Web Broadcasting
Changing web broadcasting compression and performance
• If you have a high-bandwidth connection to the Internet but
the video capture workstation has an older or relatively slow
CPU (for example, a Pentium III CPU), you could move the
lossless slider closer to Speed to reduce the lossless
compression.
• If the video capture workstation has a relatively slow CPU and
your Internet connection is relatively slow you can move the
lossy slider closer to Compression to increase the lossy
compression.
• If increasing the lossy compression reduces image quality you
can move the lossy slider closer to Quality to reduce the lossy
compression and improve the quality of the image.
Improving performance by lowering the frame rate
You can also improve the performance of web broadcasting by
lowering the frame rate. Lowering the frame rate reduces the
amount of Internet bandwidth usage by reducing the number of
frames broadcast. Lowering the frame rate also reduces the
demand on the video capture workstation CPU resources
(because fewer frames means the video capture workstation uses
fewer CPU resources to capture and compress the frames).
To lower the frame rate, from the Tools menu select Options and
then select Display. Select Limit frame rate to and set the frame
rate to a lower value.

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
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 an Epiphan Frame Grabber to a video source,
the video source sees the Frame Grabber as a monitor. Just like a
monitor, the Frame Grabber contains EDID that is used by the
video source to determine the video signal to send to the Frame
Grabber.

Usually you would operate an Epiphan Frame Grabber using the
factory installed default EDID. However, in some cases when you
connect an Epiphan Frame Grabber 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 Frame Grabber. The EDID
information in the file restricts the video signal that can be
accepted by the Frame Grabber. For example, you can upload a
custom EDID file to your Frame Grabber that reports that the
Frame Grabber only operates at 1040x768. When the video source
reads the EDID from the Frame Grabber, 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 frame
grabbers from the DVI2USB, DVI2USB Solo, DVI2USB Duo
EDIDs 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 Frame
Grabber. This page also contains default EDIDs for each
DVI2USB Frame Grabber. You can use the custom EDIDs to
restrict the video resolution of the video source connected to the
DVI2USB Frame Grabber. You can use the default EDIDs to
return your DVI2USB Frame Grabber to normal operation.

About EDID
Changing the EDID on your Frame Grabber
Use the following steps to upload a new EDID to your Frame
Grabber. The uploaded EDID is permanently installed in the
Frame Grabber and the Frame Grabber 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 Frame Grabber.
Keep the Frame Grabber 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 Frame Grabber.
6 Set the required resolution on the video source.
You may need to disable/re-enable or reset the DVI port. How
you do this depends on your DVI source but could involve
restarting the device, entering a reset command, or pressing a
reset button.
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 an Epiphan Frame Grabber, 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 Frame
Grabber supported 720x400 so the system changed to this
resolution when the Frame Grabber was connected to it.

Configuring image adjustments
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 Frame
Grabber that excluded support for 720x400. When the user
uploaded the custom EDID to the Frame Grabber, the video
source returned to operating at 640x480.
Configuring image adjustments
On Windows, from the Capture menu you can select Configure
Device and then select the adjustments tab to configure image
capture adjustments.
You can also configure image adjustments from the VGA2USB
control panel application. See “Windows Epiphan USB device
driver” on page 76.

Configuring image adjustments
The video capture application automatically adjusts image
capture settings every time it starts up. This image adjustment is
also repeated every 60 seconds during operation. So normally
you would not have to configure image capture adjustments.
However, you may have special requirements or for other reasons
have image quality problems that can only be fixed by making
image adjustments.
If image adjustments are required, you should make them in
small increments to avoid loss of image synchronization. If image
synchronization is lost, the video capture application will stop
capturing images. To start capturing images again you need to
exit from and restart the video capture application.
Note: Because image adjustments are made automatically there
are no default image adjustment settings. Also, changing image
adjustments means making relative adjustments from the settings
auto configured by the system.
Sampling Phase
Adjust the sampling phase to change the horizontal resolution of
the image. In Figure 39, the sampling phase is properly adjusted
for Image A and the sampling phase for Image B is incorrectly
adjusted. As a result Image B is not as clear as Image A.
If the image in the video capture application window displays a
similar quality of image as shown in Image B, then select and
adjust the sampling phase in small steps until a sharper image is
displayed in the video capture application window.

The PLL adjustment adjusts the vertical synchronization
properties of the image. In Figure 40, if the image in the video

Figure 40:PLL adjustment
A good indication that the PLL setting needs to be adjusted is
when there is a repetitive distortion or blurriness on the
horizontal axis of the image as shown in Image C and Image D
above.
Horizontal and Vertical Shift
Using the horizontal and vertical shift adjustments you can offset
the image position on the screen. For example, Image E in
Figure 41 shows a captured image shifted slightly to the right
(horizontally) and slightly downward (vertically). To correct the
image position, minor adjustments to these settings are necessary.

Figure 41:Horizontal and Vertical Shift
Increasing or decreasing the Horizontal setting will cause the
image to be shifted to the left or right respectively. Increasing or
decreasing the Vertical setting will cause the image to be shifted
upward or downward respectively.
Offset and Gain Controls (brightness/contrast)
The offset and gain settings control the image brightness and
contrast respectively. Increasing the offset control causes the
image to become darker. Increasing the Gain control gives the
image more contrast.

This checkbox, when enabled, allows Wide Aspect Ratio VGA
modes to be displayed by the video capture application window.
The Epiphan USB device driver may not be able to determine
whether the video source is sending a wide video mode signal.
You can select this option if your video source uses a wide video
mode to make sure that the Epiphan USB device driver selects a
wide video mode.

Select an image to be sent to DirectShow if the
Frame Grabber is not sending images to the video
capture workstation. This option replaces what
would otherwise be a blank screen with a static
image that would be captured by DirectShowcompatible image capture applications.
Scaling
If Fix Resolution is set to a resolution that does not
match the actual resolution of the video signal you
can select Pixel Resize to have the Epiphan USB
device driver resize the image (either shrink or
expand it) to match the fixed resolution. Pixel
Resize is a simple resizing method that adds or
removes pixels as required to resize an image.
If you set scaling to No Resizing the Epiphan USB
device driver does not resize the image sent to
DirectShow. If the actual resolution of the video
signal is smaller than the fixed resolution, the
image appears in DirectShow compatible video
capture applications with a border around it. If the
actual resolution is larger than the fixed resolution,
the image appears cropped in DirectShow
compatible video capture applications.

Configuring VGA modes
Limit
Select Limit frame rate to and set a frame rate that
frame rate is lower than the frame rate at which your Frame
to
Grabber can capture images. You can reduce the
frame rate to reduce the number of images
captured by the Frame Grabber. You may want to
reduce the frame rate to reduce the load on the
video capture workstation or to reduce the size of
recorded video files.
For example, if the Frame Grabber can capture up
to 60 frames a second (fps), this frame rate may use
close to 100% CPU usage on some video capture
workstations. To reduce load on the video capture
workstation you can limit the frame rate to 30 fps
without loosing very much useful data.
The valid frame rate range is from 0.01 to 60 fps.
The default frame rate is 30 fps.
Fix frame
rate
Select fix frame rate to force the frame rate to
always be the same as the limited frame rate. If the
limited frame rate is less than the actual frame rate
some frames will be missed. If the limited frame
rate is higher than the actual frame rate some
frames will be duplicated.
Configuring VGA modes
For a description of VGA modes that also describes many of the
terms used in this section, see “VGA modes” on page 48.
If you are capturing images from a VGA stream, from the Capture
menu of the video capture application you can select Configure
Device and then select the VGA modes tab to configure the VGA
modes that the Frame Grabber can operate in. You can also
configure VGA modes from the VGA2USB control panel
application.
In most cases you should not have to configure VGA modes.
Usually the Frame Grabber and VGA source can automatically
select a VGA mode.
User Guide

18. Advanced topics
Configuring VGA modes
However, configuring VGA modes can be useful if you have
special requirements or if the VGA source and Frame Grabber do
not automatically select the VGA mode that you want. To resolve
problems like this you can configure VGA modes to either limit
the standard VGA modes that the Frame Grabber can operate in
or you can add one or more custom VGA modes and configure
the Frame Grabber to operate in a custom VGA mode.
Figure 43:Configuring VGA Modes
The Frame Grabber acts like a display device. Many VGA sources
set the VGA mode that they use by checking the VGA modes the
display device can use and then setting their VGA output mode
to match. So if you can control the VGA mode that the Frame
Grabber uses you may be able to control the VGA mode that the
VGA source uses.
If the Frame Grabber and the VGA source cannot automatically
select the VGA mode that you want them to use, you may be able
to resolve this by only allowing the Frame Grabber to operate in
one or some standard VGA modes.
Page 146

Configuring VGA modes
If the VGA source operates in a non-standard VGA mode, you
can use the custom VGA mode settings to add that non-standard
mode to your Frame Grabber. The Frame Grabber can then
operate in that mode.
Adding custom VGA modes
Add custom VGA modes if you want your Frame Grabber to
operate in a non-standard (custom) VGA mode. You may want to
do this if your video source operates in a non-standard VGA
mode.
You can add as many custom VGA modes as you want for each
Frame Grabber. If you want the Frame Grabber to operate with a
single custom VGA mode, then just add one. You can add more if
you need to operate your Frame Grabber in different custom
VGA modes later.
In most cases the Frame Grabber will automatically select the
custom video mode that most closely matches the VGA output. If
you want to make sure that a the Frame Grabber selects a specific
custom video mode you can unselect all standard VGA modes
and all custom VGA modes except for the one that you want the
Frame Grabber to use.
Usually you would configure a custom VGA mode to match the
custom VGA mode of your VGA source. (So you do not need to
understand the details of custom VGA modes to add them to
your Frame Grabber.) The video capture application does not
provide any guidance in configuring custom VGA modes. You
can enter almost any value in any of the fields. So you need to
know the details about the VGA mode settings of your VGA
source then add that information to the custom VGA mode
configuration.
You can add, edit, and delete custom VGA modes. If you add
multiple custom VGA modes you can select one or more for the
Frame Grabber to use.

About the frame rate
The Frame rate at which your Frame Grabber and the video
capture application operates depends on the resolution of the
VGA or DVI source on the Frame Grabber that you are using, and
on the video capture workstation hardware.
For Frame Grabbers that do not support hardware compression,
performance and frame rate is limited mostly by USB throughput.
The theoretical limit for USB 2.0 is 60 MB/sec and the practical
limit for bulk transfers is between 20 and 40 MB/sec.
The theoretical maximum frame rate can be determined using the
following calculation:
theoretical maximum frame rate= (20000000/(n*w*h))
Where:
• w and h are the number of columns and rows in the video
mode (for example, 800x600 or 1024x768).
• n is number of bytes per pixel (from 1 to 3, see below)
The real maximum frame rate is usually lower than the
theoretical maximum frame rate because the real maximum frame
rate is limited by the video capture workstation CPU and
memory or by extra load on the USB bus (for example, if you have
other USB devices on the same USB bus).
User Guide
Page 151
18. Advanced topics
About the frame rate
For the VGA2USB Frame Grabber, n is always 2 (because the
VGA2USB Frame Grabber maximum color depth is RGB16 which
is 2 bytes per pixel).
For the DVI2USB Frame Grabber n can be from 1 to 3 depending
on the capture mode. The DVI2USB Frame Grabber maximum
color depth is RGB24 (3 bytes per pixel) as well as RGB16 (2 bytes
per pixel) and RGB8/Grayscale (1 byte per pixel).
For Frame Grabbers that support hardware compression (the
VGA2USB LR/HR/Pro, DVI2USB Solo/Duo) the maximum real
frame rate very much depends on the entropy (statistical
properties) of the input VGA or DVI signal. In other words, the
frame rate depends on how well the signal can be compressed, or
how much the next frame is different from the previous one. The
frame rate can range, from less than non-compressing VGA2USB
in the worst-case scenario (because the format for compressed
data adds extra overhead) to 60 frames per second (hardwired
limit) if almost nothing changes on the image.
