SYMBOLS
In this manual, these symbols will point out
important notes and warnings.
INTRODUCTION
If you already have a working knowledge of the
Osprey cards and their capabilities, you may
want to skip ahead to Chapter 2, Hardware and
proceed with installation.
The Osprey-300 Capture Card is a single-slot PCI
card combining analog and digital video capture
and delivering uncompressed video and audio
real time to media applications. Supporting the
latest in DV capture for IEEE-1394b (800mbs),
the Osprey-300 is an “all-in-one” analog video
capture/IEEE-1394 card that maximizes PCI slot
usage. All formatting and scaling of images
are processed within the hardware, allowing for
maximum system efficiency and speed. The
product also provides on-board audio capture
capability. This product consists of a PCI board
(based on the Conexant Bt87 8A single-chip
video capture device) and DirectShow compliant
software drivers for Windows XP.
FEATURES
The Osprey-300 can provide audio and video
to host applications from any of the following
sources:
• Decompressed DV video and audio from
IEEE-1394b DV devices
• Video from Composite sources
• Audio from Balanced or Unbalanced
analog so u rces
• Gamma correction for YUV and Greyscale
color form ats

Chapter 1: Getting to know your Osprey- 300 Card
The Osprey-300 also offers the following
features:
• OHCI c ompliant
• Cascadable architecture allows for
multiple Osprey-300’s per chassis
• Advanced DMA for ultra-high performance
(30 fps)
• Hardware audio gain control for analog
audio inputs
• Closed Caption extraction
• Hardware Cropping and Bitmap Overlay
• PCI-X c ompatible
• SimulStream ready (analog only)
FIREWIRE 800 FEATURES
The 1394b port on the Osprey -300 functions
at the maximum IEEE-1394b rated speed of
800 megabits per second. The ports are fully
backward compatible with S 100, S200 and S400
rated 1394 devices.
The Osprey card is equipped with two 1394
connectors:
• 6-pin connector for S100, S 200 and S400
rated 1394 devices (standard Fire Wire )
• 9-pin connector for the latest FireWire800
devices.
Up to 63 devices may be connected in a chain
through either of these ports.
NOTE: Although both ports can support highspeed communication, 1394b devices should
always be connected to the 9-pin connector to
ensure that connected devices take advantage of
1394 b com munication protocol en h ancements
and avoid earlier cable length restrictions. Older
1394 devices may be connected to either port
appropriate cables.
FireWire devices are designed to be hotpluggable; it is not necessary to power down
the host PC when connecting or disconnecting
devices to the Osprey 300’ s FireWire ports.

Osprey - 3 00 User ’ s Gui de
SYSTEM REQUIREMENTS
The minimum capability of the computer
required for the capture card itself is fairly
low. I t is typically the application being used
with the capture card that sets the minimum
requirements of the computer. For example,
pure video capture applications typically do
not require hefty machines. Yet the various
streaming encoding applications, for example
RealProducer or Windows Media Encoder, may
require up to dual 2 GHz processor for some of
their challenging encoding profiles.
For x86 PCs, the minimum system requirements
are as follows:
• 300 MHz Pentium II processor or higher
with at least 128Mb RAM
• One available PCI slot
• Windows XP
• Approximately 7.5 megabytes of storage
for system files
For optimum performance, we recommend at
least the following additional features.
• Video display adapter with 4 MBytes
memory minimum (1 6 Mbytes or more
recommended) and Direct Draw capability
• An up-to-date display device with
DirectDraw capabil ity
• DirectX version 9.0a or later
Minimum System Requirements for DV Editing
When using the Osprey 300 1394 ports with
video editing applications such as Adobe
Premiere Pro, the host PC must meet the
following minimum system requirements :
• Intel Pentium III 500MHz or faster
• Microsoft XP, XP Pro, or later operating
system
• UDMA 66 IDE or SCSI hard disk disk array
• 256MB or more of system RAM
• Microsoft DirectX 8.0 or newer
• Sound card capable of 16-bit stereo or
higher
The Osprey 300 F i reWir e ports use
the 1394 driver stack i ncluded in
all vers i ons of Mic rosoft Windows
XP or later operating syst ems . V i e wCast
does not install these drivers as part of the
Osprey 300 insta llation process. The analog
video capture portion of the Ospre y 300
uses drivers supplied b y V iewCast. Use of
this card i n operating systems older than
Windows XP may restrict the user to the
analog inputs only.

If your video source provides only composite
video, connect the source’s output cable to the
Composite Video In connector.
Connecti ng a n S-Video Source
If your video source supports S-Video, connect
the source’s output cable to the S-Video In
connector. Compared to composite signals, SVideo provides a sharper image with better color
separation. S-Video uses a four-pin mini-DIN
connector that provides separate Y (luminance)
and C (chrominance) signals. Refer to Chapter
6 - Osprey-300 Video Control Dialog for
instructions on configuring the driver for S-Video.
Connecti ng an I E E E 139 4/DV Source
The Osprey-300 has two DV inputs, 1394a and
1394b. D V carries digital audio and video and
both can be independently used by the Osprey-

GUIDELINES FOR CONNECTING FIREWIRE
D
EVICES
FireWire devices can be connected in any
combination of branching and chaining . There
are no SCSI-style ID numbers to set and no
termination requirements. The Osprey 300’ s
6-pin FireWire port can support up to 16
consecutive cable hops of 4.5 meters (14.76 feet)
each.
The Osprey 300’ s nine-pin FireWire 800 port
allows the use of various types of cabling
designed for 1394b operation of speeds up to
800 megabits per second. Selection of the proper
interconnect cables allows hop lengths of up to
100 meters.
FireWire 800 / 1394b devices connected to the
Osprey 300 9-pin port communicate over long
connections directly; no hub is required to gain
this added distance benefit in a pure FireWire
800 /1394b connection.
If you need to connect older FireWire devices at
a greater distance than the devices can support
directly, use a Fire Wire800 hub device connected
to the Osprey 300’s 9-pin port. FireWire 800
/1 394b hubs mak e it possible to connect older
FireWire 400 / 1394a devices up to 100 meters
apart. Neither the computer nor the remote
devices need to support FireWire 800 / 1394b
since the selected FireWire 800 /1394b hub and
its associated cables work with FireWire 400 /
1394a devices.
The Osprey 300 is designed to allow the
FireWire network to continue operating even if
the computer is shut down. Loss of power to the
computer will not affect the interoperation of
other devices on the same Fire Wire bus as long
as they are self-powered (i.e., do not require
power from the host PC ).
Pow e rering FireWi re devices via the Osp rey
300’s FireWire ports
The Osprey 300’s two FireWire (1394) ports are
capable of supplying power to certain FireWire
devices designed to receive DC power from the
host PC. There are two options available:
14
Chapter 2: Hardware Overview
• If the total DC power requirement for the
connected devices is 9 watts or less (at 12
VDC) the on-board DC power connector
does not need to be connected to a power
source.
• If the total load exceeds 9 watts, connect
a compatible power source to the DC
power connector at the rear of the Osprey
300 card, as shown below. Typically a DC
power connector from the PC’s internal
power supply of the type normally used to
supply power to a floppy disk drive may
be connected here without modification.
When this method is used the FireWire ports can
supply up to 30 watts of power.
ABOUT 1394 CONNECTORS
All 1394 devices are connected via one of three
connectors specified in the 1 3 94 standards.
• The original 4-pin connector is found on
most consumer Digital Video (DV) devices
such as camcorders. This connector
supports 1 3 94a communication but
does not support later changes to 1394
standards that allo w attached devices to
be powered by the bus.
• The 6-pin connector was introduced to
add the option to power the connected
device via the 1394 bus.
• The 9-pin connector was introduced to
support the bus speeds of FireWire800
and to support enhanced device
identification and control protocol. The
9-pin connector is described as Bi-Lingual
since you are allowed to connect any 1394
device via the appropriate adapter cable.
Cables with appropriate combinations of all of
these connectors are available from most AV
equipment retailers and electronics.

CONNECTING ANALOG AUDIO WITH THE
O
SPREY-300
The Osprey-300 audio connectors are made for
line level audio stereo equipment, such as VCR or
DVD outputs and can also take headphone level
outputs when the volume is adjusted midwa y
between high and low settings. It should be
noted that if you are using a camcorder or VCR
with only a single audio output, the volume
needs a slight adjustment.
Although the Osprey-300 accepts line level
inputs, the standard microphone shipped with
most soundcards is not compatible. You need to
use a powered microphone using connectors with
1-volt pea k-to-peak output.
RCA-style connectors for left and right line-level
audio are used on the Osprey-300.
The selection of audio input to capture is
independent of the video input selection.

TWO INSTALLATION SCENARIOS
There are two main situations that might apply
to you:
• Scenario 1: Osprey Card( s) not Physically
Installed in the PC
• Scenario 2: Osprey Card(s) Physically
Installed, but Osprey Software not
Installed
In all cases, the most efficient and complete
installation method is to run the setup.exe
program on the product CD or in the web
package that you downloaded. The setup
program automates the Plug and Play steps
required to install the drivers and ensures that
they are performed correctly. It also installs the
bundled applets and User’s Guide. I f you have
multiple Osprey capture cards in the system it
configures all of the boards at the same time.
You can skip the detailed instructions if you are
upgrading from one Osprey driver version to
another . Just run the setup.exe file, and all the
updated components will be installed.
Scenario 1: Osprey Card(s) not P hysically
Installed in the PC
This is the method that we recommend if you
are installing an Osprey card for the first time
on a system, and the Osprey software has not
yet been installed. This scenario is called the
“Preinstall Scenario” . After the install is run ,
as soon as an Osprey card is installed in the
PC, it is detected and its drivers are started
automatically.
To preinsta ll the Ospre y drivers:
1. Using Windows Explorer, locate and
access the CD-ROM drive containing
the Osprey Installation CD-ROM .
2. Navigate to the WINXP directory .

After completing the Found New Hardware
Wizard, the applications for the Osprey driver
must also be installed. To do this, navigate to the
directory containing the Windows XP driver for
your Osprey card, and run SETUP.EXE.
For detailed steps , please refer to Option A: Run
the Installation Program ( Recommended).
TESTING THE INSTALLATION
1. Veri fy th e h a rdware in sta l l at i on
is compl ete , in acco rda nce wi th
the directions in Chapter 2.
2. Connect a camera, VCR, or
other video signal source to the
Osprey card’ s con nectors.
3. Open the Osprey Capture
group in the Start menu.
4. Click the SwiftCap icon.
5. Verify the screen displays a still video
frame from the Osprey card. Click the
Preview button. The screen should
display moving video frames.
6. If the video area is a plain blue fi eld , it
could be for one of the following reasons:
• The driver is looking for video on the
wrong input connector. You can either
move the video cable to another
connector, or reconfigure the driver using
its Control Dialog (refer to Chapter 6 Osprey-300 Video Control Dialog).
• The video source is not turned on or
activated.
7. If the video area is scrambled or has bad
color , the signal format of your video
source may be different from the signal
format selected in the driver software.
Since the driver defaults to NTSC-M signal
format, users of PAL and SECAM equipment
always need to change the driver’s signal
format the fi rst time they run the driver .
Please see Video Standard in Chapter
6 – Osprey-300 Video Control Dialog.

It is useful for testing the installation and for
general purpose viewing of video. Refer to
Chapter 8 for instructions on using this applet.
CONFIGURING FIREWIRE DRIVERS FOR

Windows XP will typically install the FireWire
drivers as a “Texas Instruments OHCI Compliant
IEEE 1394 Host Controller”. Successful
installation can be verified in the Windows
Device Manager (see figure 1 in Chapter 4).

CHAPTER
4
The Osprey-300 IEEE 13 94 inputs connect
to standard Microsoft drivers rather
than to the Osprey AVStream driver.
Osprey customers who are familiar with
the Osprey-500, -540, and -560 should
understand that the DV implementation
is completely different. On the Osprey5XX cards, the D V connector and capture
hardware sit behind the Osprey audio and
video capture devices and are controlled by
the Osprey driver. On the Osprey- 300, the
DV is an entirely independent device.
The Windows XP Device Manager
1
If you look at the Windows XP Device
Manager (figure 1) after installing an
Osprey-300 you will see something like
this. Under the category “I EEE 1394 Bus
host controllers” there wil l be a n entry for
the Texas Instruments controller on the
Osprey-300. This device is automatically
activated whenever the card is plugged
into the system. If you plug a DVCam into
the Osprey card, an entry for it will appear
under the “Imaging devices” heading.
Both the 1394 controller and an y devices
plugged into it are logically distinct from
the Osprey-300 analog audio and video
devices shown under Sound, video and
game controllers.
27
Osprey - 3 00 User ’ s Gui de
In theory you should be able to connect any
1394 device to the card, not just a digital video
(DV) source. In this chapter, however, we focus
on using the 1394 connector with DV devices
such as camcorders.
Most major multimedia applications will
recognize DV devices and work with them fully.
For example, we have verified that Windows
Media Encoder 9 supports a DVCam attached
to an Osprey-300. With ma jor applications
the DV connection should “just work” and the
information here is for background and reference
only.
SPECIFICS OF DV CAPTURE
The DirectShow filter used for DV capture is
called the “Microsoft DV Camera and VCR”. This
filter can capture video only, or audio and video
together. I n this respect it is different from the
Osprey analog capture driver, which has logically
distinct modules for audio and video capture.
Unlike the Osprey analog driver, which captures
video into many user-selectable sizes and
formats, the DV capture filter delivers just one
format for each video standard.
For 525-line (NTSC) video, the video size is
720x480 and the video rate is 29.97 frames per
second.
For 625-line (PAL/SECAM) video, the video size
is 720x576 and the video rate is 25 frames per
second.
The video format is always a compressed format
designated w ith th e fo u r-character identifier
“dvsd” (case-sensitive, and lower case). In this
format, one NTSC video frame is 12 0,000 b ytes,
and one PAL./SECAM video frame is 144,000
bytes. By comparison, one uncompressed
YUY2 NTSC frame, requiring 2 bytes per pixel ,
is 691,200 bytes, and one uncompressed YUY2
half-siz ed frame (360x240) is 172,800 bytes;
that is to say, the half-sized YUY2 frame is
significantly larger than the full -s iz ed dv sd frame.
28
Chapter 4: Digital Video on the Osprey-3 00
The dvsd format comes in two flavors - videoonly, and audio + video interleaved. The audio
+ video data rate is slightly higher than the
120,000 or 144,000 bytes per frame quoted
above - for NTSC it is about 129, 000 bytes per
frame, or about 3,866,130 bytes per second.
The dvsd format can be captured directly to
AVI files. There are two subformats - Type 1
and Type 2. The Type 1 format stores the audio
+ video data as a single stream. The Type 2
format stores the audio and video data as two
separate streams. The Type 1 format is more
compact and efficient but is not backwardcompatible with Video for Windows. Osprey’s
SwiftCap application, as described below,
currently supports only the Type 1 format. With
other suitable applications the Osprey-300 D V
conne cto r can cap t ure in e ither fo rmat.
Several additional DirectShow filters support the
DV capture module.
The most important is the DV Video Decoder.
This filter accepts dvsd video-only streams as
input. As output it delivers an uncompressed
YUY2 stream at full, half, 1/4 , or 1/8 si z e. This
filter is alw ays used when rendering v i d eo.
When capturing video without compression, it
is normally not used, but could be useful for
capturing quarter-sized or 1/8-sized video, at
some savings in data rate. (Note that the fulland half-size options would increase the data
rate to no purpose.) When video is captured
with compression , a D V Video Decoder will be
placed in front of the compressor, to deliver the
YUY2 input that the compressor uses.
The other specializ ed DV filter commonly used
in capture is the DV splitter, which accepts a
dvsd audio + video interleaved stream as input,
and outputs dvsd video-only on one pin , and
standard uncompressed audio on the other.
Following the how-to description of SwiftCap,
there are some sample DirectShow graphs that
show some of the ways these components can be
connected together.

SWIFTCAP
This section provides specific information about
how the bundled capture application SwiftCap
supports DV capture on the Osprey- 300 . Note that
this manual also contains a more complete general
reference section on SwiftCap that is oriented
towards its support of the Osprey analog driver.
Note - only more recent versions of SwiftCap work
with DV devices. The “Help -> About SwiftCap”
message should show a version number 3.1. 1.0
or later, and be copyrighted 2004 or later. The
SwiftCap version supplied with the Osprey-300 driver
package is 3.1.1.0.
The main features of SwiftCap’s DV support are
highlighted in figure 2.
If a device such as a DV camcorder is connected to
the Osprey-300, it will appear in the video device list
as a “Microsoft DV Camera and VCR”. The Capture
Settings dialog will appear as shown only when a
DV device is selected ; for analog vidcap devices the
dialog is set u p d i fferently.
SwiftCap’s Digital Video Capture Options
2
Note that even though a DVCam is an audio + video
device, DirectShow classifies and enumerates it as
a video device only . S wiftCap adheres to this logic
by displaying a DVCam as a video device choice, but not as an audio device choice. If you want to capture
both audio and video from a DVCam, you should select “Video” in the Capture group at the right. If you
want to capture DV video, and audio from another analog source, select “Capture Both” and uncheck
“Capture DV Audio” (You can even work to capture both DV audio and analog audio at the same time).
If you select “Preview DV Audio”, S wiftCap will preview audio both in preview-only mode and when capture
is happening. (SwiftCap does not preview audio with analog capture devices.) This capability could be
useful when capturing audio from a remote or recorded source - but you will want to turn it off for capture
from a live source , to a void feedback.
Two checkboxes in the Video group, “Capture DV Audio” and “Preview DV Audio,” control DV audio.
The video Size control affects size of previewed video only, not captured video. As previously explained,
dvsd video from the D V Video Capture Filter is always full sized and in CCIR-601 format, that is, 720x480
NTSC or 720x576 P AL/SECAM. While a DV Video Decoder Filter could be used to downsize the video,
SwiftCap does not currently support this. SwiftCap also does not support compression of DV video at this
time.
As you can see, the rest of the Video Format controls are greyed and read-only. The video format from a
DVCam is always “dvsd”, as described above. SwiftCap will determine for you whether the camera is NTSC
and 30 frames per second, or PAL and 25 frames per second. The aspect ratio from DVCams is alwa ys
CCIR-601, meaning that the pixel width is 720 .

GRAPHS
This section contains more technical information that may give some users helpful insight into DV capture
and rendering operations. The illustrations are DirectShow graphs as displayed by GraphEdit.
For still more advanced information, refer to the DirectX 9 SDK documentation available from Microsoft.
This graph shows the simplest possible video-only DV capture graph.
This is the simplest possible audio + video DV capture graph. The difference is that the DV Capture Filter’ s
A/V Out pin is used, which delivers an interleaved A/V stream rather than a pure video stream. The AVI file
will be “Type 1” - that is, the audio + video will be structured as a single stream; this format is efficient but
is DirectShow-only, not backwards-compatible to Video for Windows.
This is the simplest possible audio + video “Type 2” graph. The AVI file, now Video for Windows compatible,
is now structured as an “auds” stream plus a “vids” stream. The DV Splitter Filter splits the interleaved A/V
stream in to a dvsd video stream plus a PCM audio stream.
