1. Introduction
The NCast Digitizer Capture Card 3.0 functions as an RGB, DVI, and video capture
device. The DCC-3 card also provides customizable Picture-in-Picture (PiP) capabilities
for video within graphics display. The DCC-3 card supports up to UXGA resolution and
delivers SXGA at 30 fps. The DCC-3 card is primarily designed for applications
requiring high resolution and high frame rates. Example applications include webcasting
over IP, local capture, remote viewing, and replacing dedicated monitors.
The DCC-3 is a PCI plug-in card, and is compatible with Windows XP/2000 and Linux
operating systems. Drivers for both operating systems are available at
www.ncast.com/downloads. The card is designed to work with software such as
Windows Media Encoder for real time streaming, presentation authoring, and archiving
of high resolution/frame rate graphics and video.
2. Hardware Overview
The DCC-3 card is designed to capture high resolution and frame-rate graphics. The card
accepts inputs from DVI and HD15 RGB inputs, and also S-Video and BNC Composite.
The RGB data is transferred using the PCI bus master DMA.
Resolutions
The DCC-3 card supports resolutions up to UXGA (1600x1200) from the RGB and DVI
sources. Scaling options also are available. For instance, a smaller resolution such as
1024x768 can be sent at either the original resolution, or scaled to a different resolution.
For instance, the DCC-3 can accept a 1280x720 input and scale it up to a 1600x1200
resolution. Ultimately based upon user settings, the resolution from the input signal will
be scaled up/down to the selected resolution. For a list of support resolutions by the
DCC-3 card, please reference Appendix A.
Frame-rate
The DCC-3 card is designed to capture a maximum of 30 fps. of 1280x1024 and 18 fps.
of 1600x1200. However, the highest possible frame-rate is dependant upon the signal
frequency, PCI bridge and CPU of the host computer. For instance, the user can expect a
higher frame rate by using an Intel P4 @ 2.0 GHz then a P4 @ 1.06 GHz.

Video Capture
The DCC-3 provides full frame-rate signals from S-Video, Composite and DVI inputs, at
both PAL and NTSC resolutions. Odd and even frames are combined during capture, and
de-interlacing is implemented in the driver code.

4. Software Overview
Windows Driver
The DCC-3 can be installed by downloading the Digitizer Capture Card v 3.0 Drivers
from the NCast website at http://www.ncast.com/downloads.html. Once the driver has
been downloaded, double click on the .zip icon and follow the installation instructions as
outlined later in this section.
The Windows Driver offers the most important functionality to the user applications.
The driver enables the card to be compatible with the Windows 2000 Kernel Streaming
Page 4 of 15
Model, and therefore the DCC-3 should be usable with most Windows video capture
programs.
The DCC-3 and driver have been tested with the following Windows programs:
•
•
•
•
•
•
Windows Media Encoder 9 Series
Real Producer
Windows Movie Maker
Windows Messenger
VLC
MSN Messenger
Functionality
As the DCC-3 captures graphics and video requires constant output resolution, some of
the operations like de-interlacing and scaling must be turned on or off before capture
begins. As the DCC-3 can switch between interlaced and non-interlaced modes and also
modes with different resolutions, the following functionality was placed within the
driver:
•
•
•
•
The DCC-3 tries to capture 30 fps., but most programs (like Windows Media
Encoder) are able to drop frames if the user wishes to capture less than 30 fps.
If there is no signal detected, the DCC-3 will output 30 fps. of black screen.
The DCC-3 is able to switch selected PiP and main inputs on the fly. While
changing input signals or detecting a new resolution, a black screen will be
generated.
To change the selected inputs, get information about the current resolutions,
adjust the PiP size and format, and update the firmware the user can reference the
DCC-3’s property page in Windows, or use the application properties such as in
Windows Media Encoder.

Digitizer 3 Applications
An optional application is available for download at
http://www.ncast.com/downloads.html. The Play Cap Moniker application, the
application currently available, demonstrates to users how to access DCC-3 Inputs using
Direct Show and the provided DLL library. Through these interfaces, users can test
controls for:
• Selecting current inputs on both main and PiP windows
• Switch between PiP and Full Screen modes
• Change size of PiP and Main windows
• Adjust position of PiP and Main windows
The description of access to the API is outlined in “ncastwd1.idl” file, which compiles
with Microsoft IDL compiler (MIDL). The file used to access this functionality is
“ncastwd1_i.c”.
