A specific produc t is r e fe r r ed by name, i.e. 400, 450, 460, etc.
1.1 Description of IV-460
Integrated VGA
Controller
The Image / VGA-460 (IV-460) is a single slot, PCI Bus frame
grabber and video digitizer with integrated VGA controller. It
captures and displays RGB/monochrome video on a standard VGA
or Super VGA screen. It works as a standard VGA Adapter in any
of the PCI Bus slots. The IV-460 includes device drivers for
Windows 9X, NT and W in2K. Dr ivers for other operatin g system s
may also be available. Please contact the Customer Support
Department of MuTech Corporation for the most up to date
information on drivers.
Standard or Non-
Standard Video
The IV-460 is capable of digitizing video signals from a standard/
non-standard camera. The video can be either monochrome or
RGB color. The timing can come from either composite video or
separate sync/clock. The digitized video data are stored in the onboard video buffer and mixed with the VGA signal for display on
the computer monitor.
Trigger & Expo.
Control
The IV-460 is capable of accepting an external Event Trigger,
generating a general purpose Strobe Signal to control the exposure
/ integration of the camera, and then receiving a Grab Trigger for
capturing single or multiple frames of video.
2 Introduction
Revision 1.0 Image/VGA-460 User’s Guide
Savage4 Pro
Accelerator Chip
from S3
The IV-460 needs a PCI Bus slot. If there is a VGA adapter on the
computer motherboard, the IV-460 can replace it an d become the
primary VGA display controller. The VGA controller of the IV460 is the S3 Savage4 Pro Accelerator Chip (possibly with
different versions and different revisions). The IV-460 is delivered
with onboard VGA BIOS from S3.
Connectors
The IV-460 has three connectors. The first is the Video Input
Connector which takes either Monochrome Video or RGB Color
Video from a camera. This is a High-Density DB-15 male
connector. This connector also provides connections for the Event/
Grab Trigger, the Strobe, and camera power output. The second is
the VGA Output Connector, which provides VGA display signals
to the computer monitor. This is a High-Density DB-15 female
connector. The third is a 50 pin header connector on top of the
board, which can be connected, via a ribbon cable to a DB-50
connector on a second bracket. This connector provides th e
maximum possible connections to the IV-460 board, including 4
monochrome video, 2 sets of RGB video, 2 sets of external sync
and clock, 4 sets of Event-Strobe-Trigger and camera power. For
customers who need to utilize these connection, MuTech provides
an optional Ribbon Cable (MVC-D32). A custom cable from the
DB-50 connector must be made by the customer.
Major
Components
The Image / VGA-460 board consists of the following major
components:
PCI bus interface
VGA graphics controller
RAMDAC
Buffer memory, 8 MB (16 MB optional)
10 bit monochrome A/D Convert e r (only 8 bit data are used)
3 x 8 bit RGB A/D Converter
Input LUT
Grab and Exposure Control Unit
Sync Stripper, Separator and PLL
The auxiliary circuits
1.2 Options
The following options are available for the IV-460:
Introduction 3
Image/VGA-460 User’s Guide Revision 1.0
Options
8/16 MByte Video Buffer Memory
Security Device -a 256 x 8 bit EEPROM (XICOR X24C02)
with write protection jumper is implemented on the board
(must be provided by OEM or software developer)
RS-170 or CCIR Sync Generator to provide standard drive
signals to camera
1.3 VGA Display Modes
Without the video window display, the IV-460 supports all VGA /
SVGA display modes, only limited by the amount of on board
memory.
When the video window is on, the display resolution and/or color
depth are further limited. The IV-460 has shared memory
architecture. In this architecture, the video display, the VGA
overlay, the video capture, and the host access all compete for the
same limited memory bandwidth. This will limit the maximum
spatial resolution and/or color depth. The next table shows the
resolution and color depth tested for the IV-460.
Note
The above listed resolution and color depth are also limited
by the on board memory amount.
1.4 Video Capture
Video Inputs
The IV-460 board digitizes either RGB color or monochrome video
signals. It supports up to 4 monochrome video inputs or up to 2
RGB video inputs. When the default connector (DB-15HD) is
used, the maximum video input combination is limited by the
available connections. The channel switching is under software
control. The monochrome video is digitized into 8 bits which is
further combined with dummy chrominance data to form 16 bit
pixels in YCbCr 4:2:2 format (per the CCIR601 standard). The
RGB color video is digitized into 3 x 8 bits which are either stored

in 24 bit pixel format or combined with a dummy byte to form 32
bit pixel format. Capturing and displaying of the video are real time
(30 fps for RS-170, 25 fps for CCIR).
Video Window
The IV-460 supports only one video window. Software can control
the settings of the Top / Bottom Reference Level of the A/D
Converter, as well as the Clamping Leve l of the video si gnal. A 256
x 8 bit input LUT i s avai lab le for m on ochr ome vide o. Thr ee 256 x
8 bit input LUTs are available for RGB video. In both cases, there
are 16 banks in each of the LUTs. The user may pre-load them with
16 different look-up-tables and switch them during the vertical
retrace periods. All LUTs may b e bypassed.
Scaling
The video scaling is implemented by programming the PLL. For
standard RS-170(CCIR) video, the default PLL setting will
generate 640(768) pixels per line. This corresponds to non-scaled
capture with a 1:1 aspect ratio.
Display Mixing
There are basically three different working modes for displaying
and mixing of video and graphical content. T hey are the:
Opaque Mode
Color Key Overlay Mode
Chroma Key Underlay Mode
Opaque Mode
In the Opaque Mode, the video content is displayed in the video
window and the graphical conten t is di splayed on another part of
the screen.
Color Key
Overlay Mode
In the Color Key Overlay Mode, the graphical content may overlay
the video content in the video window. This overlay is controlled
by the Color Key (or Index Key). If the color of the graphical
content is the same as the Color Key, the user will see-through that
pixel and see the video content under it. Otherwise the user will see
the graphical content.
Chroma Key
Underlay Mode
In the Chroma Key Underlay Mode, the graphical content may
underlay the video content inside the video window. This is
controlled by the Chroma Key Register settings (one set of registers
for each of the R, G, and B channels, in the case of color video). If
the video pixel color is within the Chroma Key color range, the user
will see through the video pixel to the graphical content under it.
Otherwise the user will see the video content.
Zooming
The captured video m ay be zoomed up by an arbit rary ratio, i n both
directions, on the way to being displayed on the monitor.
Introduction 5
Image/VGA-460 User’s Guide Revision 1.0
Trigger &
Exposure Control
The IV-460 is designed for industrial use. It provides a general
purpose Event Trigger Input, a general purpose Strobe Output and
a Grab Trigger Input. The Event signal is used to start the camera
control-capturing sequence. The Strobe could be used to reset the
camera, to control the exposure / integration time, or to strobe a
flash light. When the desired frame / field is ready, the Grab
Trigger is used to capture the desired frame / field. There are 4 sets
of E-S-T signals, selectable by software, so each of the video
channels may have its own control.
1.5 Software
Utility Programs
Several utility programs are delivered with the IV-460 board. They
can be used for testing the installation, simple debugging, and
demonstration purposes. They can also be used as utilities for
capturing video and saving to files. The utility programs provided
support Extended DOS, Windows 9X, NT and Win2K. Also
distributed are VGA drivers for Windows 9X, NT and Win2K
(these drivers are available for down-loading from the S3 home
page as well as from the MuTech home page). All drivers are
directly licensed from S3.
MuTech does provide full customer support for the utility
programs and the Software Devel opment Kits described below.
1.6 Software Development Kits
MuTech offers Software Development Kits (SDKs) for OEMs or

VGA BIOS PROM
3.2 Overview of the Component Blocks
A simple functional description of each of the blocks is given in
this section.
Video Input &
A/D Converters
This unit has the following functional blocks:
Video Input MUX: Selects between 4 monochrome video
and 2 sets of RGB video signals. If only a DB-15HD connector
is used, the selection is further limited.
A/D Converters: Digitize the video signal.
PLL: Generates the video pixel clock which is locked to the
video signal.
Sync Separator: Generates the H+V sync and the field signal
needed by the rest of the board.
Input LUT
The input LUTs are SRAMS. The loading of the LUT is relatively
slow and is not recommended during grabbing. The user should
pre-load the banks with possibly needed LUTs before starting the
grab.
The input LUT may be bypassed by software. This function will
send unmodified data to the display processor.
Monochrome mode has 1 luminance LUT channel, there is no
LUT for chrominance chennel.
RGB mode has 4 LUT channels, three each for R, G and B, the
4th one is a dummy LUT.
In both modes, there are 16 banks of each LUT channel. The
banks may be switched quickl y, duri n g ve r ti cal re t r ac e, by
software.
Grab & Exposure
Control
This unit controls the triggered capturing, and provides the general
purpose Strobe signal to control the exposure. This block includes
the following sub-blo c ks:
Signal Mux: Several MUX control the selection of 4 channels
of E-S-T signals. They may be used to service up to 4 cameras.
Event Trigger Input: This TTL level input controls the enabling/disabling of the event trigger as well as its polarity.
Architecture 21
Image/VGA-460 User’s Guide Revision 1.0
Strobe Generator: This TTL level output strobe (used for
exposure or integration control) can be generated from either
the Event Trigger Input or a software command. The duration/
polarity are also controlled here.
Grab Trigger Input: Controls the starting/stopping the video
capture. The polarity is also controlled by this unit.
Trigger Functions
These trigger functions are available.
Stop acquire on trigger
Start continue acquire on trigger
Grab next frame.
Grab next field.
Grab next odd field.
Grab next even field.
Frame Buffer
The Frame Buffer is described below:
Total Size: 8 MB (16 MB optional).
Organization: As a one-dimensional linear array (data are
stored consecutively).
Locations: The VGA data and video data share the same
memory buffer, but at different segments. Usually, the VGA
data occupies the first segment, and the video data is stored
toward the end of the buffer.
Monochrome Pixel Data Format: The pixels are stored in
the format Y-dummy(0x80)-Y-dummy(0x80).
RGB Pixel Format: The pixels are stored in either 32 bit format - XRGB (X is the MS Byte), or 24 bit format - RGB (R is
the MS Byte).
Bus Interface and
Central Control
Unit
This is the most complicated block. It consists of the following subblocks:
PCI Bus Interface: Provides the interface for CPU access.
Capturing Control: Controls the interface to the A/D
Converter, and the start/stop of the video capture.
Memory Controller: Interfaces with the Frame Buffer,
generating the addresses as well as the control signals for the
22 Architecture
Revision 1.0 Image/VGA-460 User’s Guide
buffer memory.
Display Controller: Controls the data fetching, the timing,
the sync signal generation etc. for the display process.
Other Interfaces: Miscellaneous interfaces, e.g. on board serial interface.
Display Block
This block performs the function of displaying the VGA and video
data on the monitor screen. It consists of:
Streams Processor: Controls the data flow of the VGA and
video streams for display.
LUT: VGA Look-Up Ta bl e, defines the display palette.
Color Space Converter: Transforms the YCbCr video data
into RGB format.
Key & MUX: Generates the KEY from Color/Chroma
information, then uses the KEY to control the selection of the
data to the DAC block.
DAC: Converts the digital data into an analog RGB signal and
drives the monitor.
VGA BIOS
This is an EPROM. The BIOS is read out during boot-up through
the PCI interface block.

Appendix A: Jumper Settings
There are 4 groups of jumpers on the Image/VGA-460 Board. The
first group (JP) is for 75 Ohm termination of the video input
signals. The second (PJ) is for camera power output control. The
third (CJ) group is for user configuration control. The last (WJ) is
for Security PROM write protection. Table A.1 lists the IV-460
jumpers, their functions and their factory default settings. Figure
A.1 shows the positions of the jumpers on the IV-460 board.
